THE ROLE OF RECENT MAMMAL SYSTEMATICS AND TAXONOMY RESEARCH IN ESTABLISHING THE NATIONAL BIODIVERSITY CONSERVATION

STRATEGIES IN ROMANIA

Keywords: mammals, systematics, taxonomy, conservation, publications.

Despite the fact that mammals were among the first animals known to humans both for their curiosity to understand their way of life, and especially for economic benefits (food, clothing, traction, various industries, the recreational side of hunting), they are still scarcely studied from a systematic and taxonomic, biological, physiological, ethological, etc. point of view. Clarifications are still needed on the systematic and taxonomic positions of some mammal species in the Romanian fauna. An adequate methodology for assessing mammal populations in general and those of hunting interest in particular, has not yet been adopted. That is why there are long debates when it comes to the conservation status of some species, regarding the establishment of restrictive measures to restore the populations of other species. In order to understand the need for more in-depth knowledge of mammals, this article delves into their knowledge in the times of antiquity and the evolution of this knowledge throughout history. We also illustrate the need for theriological research through the Bibliographic List of 462 articles and books published about mammals in Romania's fauna in the last two decades.

Keywords: policy tools, biodiversity, spatial planning, ecological corridors, benefits.

In Romania, the uncontrolled expansion of built-up areas

contributes to the loss of biodiversity and fragmentation of land, and appropriate policy instruments must be developed or improved in order to avoid this situation. Green infrastructure can prevent the negative effects of development and therefore it should be included in territorial development plans and policies. However, although the importance of green infrastructure is widely recognized, putting in practice these policies is still difficult. The article assumes that due to the different scales of application, green infrastructure must and can be applied in spatial planning policies and in other related public policies. The way in which green infrastructure and its associated aspects (such as connectivity, ecological corridors, benefits, measures, planning) are referred to in the Romanian legislative framework is analysed, in order to find which political tools promote their implementation. The method consists in reviewing the most important national policy documents and identifying their references to 7 keywords that are related to the establishment and management of green infrastructures. To the obtained results were added the conclusions drawn from workshops in which representatives of decision-makers in the fields of environment and spatial planning debated on this issue. The final results confirm that there are currently many legislative instruments promoting green infrastructure in Romania, but these are not enough, requiring a

multidisciplinary approach for their improvement. A favourable situation is that of ecological corridors, components of green infrastructure, for which steps have already been taken, including at political level, the environmental legislative framework going to be accordingly adapted. Thus, after the legal identification of ecological corridors, they are going to be implemented into territorial planning documents at different scales.

THE GRANODIORITES WITH BIOTITE NODULES IN THE NORTHERN SEBEȘ MOUNTAINS

(SOUTH CARPATHIANS)

Geological Institute of Romania, 1st Caransebeș Street, 012271 - Bucharest, Romania.

E-mails: ionstelea@yahoo.com; monica_ghenciu@yahoo.com

Keywords: granodiorites, biotite nodules, Sebeș Mts., Romania.

A large swarm of rhyodacite dykes and some granodiorite bodies outcrop along the Rășinari Shear Zone in the northern Sebeș-Cibin Massif. The rhyodacites are Cretaceous in age and the granodiorites are older (Liasic probably) since they frequently occur as lithic restites in rhyodacites. Two granodiorite bodies on the central sector of the shear zone contain spheroidal biotite nodules, a rare petrographic feature found only in granitoid rocks. The typical internal structure of the nodules is quasi-concentric, with thick shells of biotite arranged around a central core consisting of intergrowth of biotite-quartz and biotite-plagioclase. The large nodules of 3-5 cm are polycentric, with two or three secondary cents around the core. According to Van Diever (1970), the biotite nodules in the granite of Craftsbury (Vermont, US) were formed by the adhesion of biotite sheets around some gas bubbles to which additional bubbles were attached during the ascending migration through a low viscosity, volatile-rich magma. The nodules float until the collapse of the gas bubble and the nodules with uncollapsed bubbles agglomerate in the ceiling of the magmatic chamber. The pegmatitic segregations in the granodiorites with biotite nodules from the north of the Sebeș Mountains corroborated with our microscopic observations support this hypothesis.

Keywords: arfvedsonite, Cotmeana Piedmont, source area.

The Cotmeana Piedmont consists of large deposits of Lower

Pleistocene gravels, with a great petrographic variety and multiple source: Carpathian, Subcarpathian and Intracarpathian. During the research for the doctoral thesis, regarding the petrographic composition of gravels, we identified two pebbles of quartz-feldspathic gneisses with arfvedsonite. The protolith of the two gneissic samples (3743 A-1 and 3744 A-6) is a porphyritic granite. In addition to arfvedsonite, the mineralogical association of sample 3743 A-1 also contains quartz, oligoclase (porphyroclastic) microcline, biotite, muscovite, magnetite, epidote, allanite, clinozoite, apatite, zircon and sphene. The mineralogical association of the sample 3744 A-6 also contains oligoclase, albite, quartz chlorite, hematite and apatite. Porphyritic granites with arfvedsonite, of Liasic age, outcrop in the north-eastern Făgăraș Mountains, inside the Codlea Basin. This is the provenance area of the two granitic gneisses with arfvedsonite in the Cotmeana Piedmont.

Keywords: Cotmeana Piedmont, gravels, boulders.

During the field research for the doctoral thesis of the first author, the pebbles inside the Cotmeana Piedmont were described using the following terms: boulders, for the pebbles with dimensions of 20-50 cm, coarse gravels, for pebbles of 10-20 cm, gravels, for pebbles of 3-10 cm, small gravels, for pebbles of 1-3 cm and fine gravels, for pebbles under 1 cm. Boulders were found in 22 observation points, 8 on the north-eastern edge of the piedmont and 14 on its western edge. By order of frequency, the petrographic types of boulders are: quartzo-feldspathic gneisses, quartzites, siliceous rocks, quartz, pegmatites, amphibolites, eclogites, augen gneisses, red sandstones, rhyolites, granites and granodiorites. Specific for the western zone are the red sandstones, amphibolites and jasper boulders. Boulders of rhyolite and augen gneisses appear only in the north-eastern zone. The presence of boulders in the northern part of the piedmont is explained by the proximity of this zone to the Carpathian source area, but their presence in the south-western zone is somewhat surprising, this zone being further from this source area. The boulders along the western edge represent the clastic material input, Carpathian and Intracarpathian, of a torrent with high transport power (the Olt paleo-River).

Keywords: chalcedony, jasper, opal, silicified wood, moganite.

From a geological point of view, the southern slopes of the Apuseni Mountains are mainly composed of Jurassic and Cretaceous ofiolites and laramic volcanites, along with quaternary detritical deposits. Microcrystalline and amorphous silica gems were studied along with different varieties of common silica-bearing rocks, i.e., agate, chalcedony, jasper, opal and silicified wood. The optical microscopy studies revealed grainy to fibrous textures in the case of chalcedony and agate and reticular textures in the case of silicified wood. The analyses showed that the red colour of the gemstones is due to the presence of iron oxides and sesquioxides. X-ray diffractometry pointed out a main peak at 26.64 degrees/2θ, characteristic to quartz, a main peak at 22 degrees/2θ, assigned to cristobalite, and another peak around 20 degrees/2θ, specific for moganite. In addition to α quartz, Raman analyses showed the presence of moganite, with a strong band located around 501 cm-1, and also of graphite, with bands around 1360 cm-1 and 1576 cm-1 in the silicified woods. Moganite was identified during this study for the first time in Romania. Based on the transformation, at a microscopic scale, of moganite into microcrystalline quartz, we can establish the degree of diagenesis of the sediments, with direct indications regarding the age or maturity of agates from Romania. In spite of the common opinion that the silica gems only result from volcanic processes, an important role of diagenesis was inferred, based on the analysis of the bentonitization of the volcanic clasts.

CONTROLLING FACTORS IN THE DEVELOPMENT OF THE CAVES IN NORTH-WESTERN OLTENIA (ROMANIA)

GHENCIU Monica

Geological Institute of Romania, 1st Caransebeș Street Bucharest, Romania.

E-mail: monica_ghenciu@yahoo.com

Keywords: Oltenia, caves, faults, stratification.

The karstification processes of carbonate massifs are controlled by two main factors, tectonic and stratigraphic, both implying the presence of discontinuities inside the rock, respectively tectonic planes and stratification. Their role is differently assessed by various authors. Our structural research in north-western Oltenia, correlated with the main development directions of ten caves in the region, shows that the tectonic factor is decisive. The karstification directions for six caves (Fușteica, Apa Moiștii, Cloșani, caves no. 1 and 3 in Steiul Orzeștilor and Cave no. 9 on the Motru Sec Valley) are strictly tectonically controlled by faults (the Obârșia Cloșani and Izverna faults, the Balta-Baia de Aramă tectonic corridor and the Motrului Fault) and associated fissure systems. For the formation of three caves (Lazului Cave, the Podul Natural Cave and the Cave no. 8 on the Lupșa Valley) both factors competed. Only one cave, the one near the Tismana Monastery, developed on the limestones stratification.

Keywords: Piatra-Neamț, Paleontological Reservation, Cozla, Oligocene, Fish fossils.

The city of Piatra-Neamț is dominated to the north, east, and

south by the Cozla, Pietricica, and Cernegura Mountains. From a geological point of view, these mountains are integrated into the Bistriţa Half-Window of the Marginal Folds Nappe (Eastern Carpathians); stratigraphically, the geological formations from the Cozla Mountain, belong to the Upper Eocene (41.3-33.7 M.A.) and Oligocene (33.7-23.8 M.A.). The fossil fish-bearing outcrops from the Cozla Mountain are founded in the Bituminous Marls and Lower Dysodilic Shales of tje Early Oligocene age. Historically, the first fossil fishes from Romania were collected by Leon C. Cosmovici in 1883, 1884, and 1885, from the Cozla Mountain, and were described in 1887 in the first palaeoichthyological scientific paper in Romania. Starting in 1957, Mihai Ciobanu began to excavate fossil fishes from the Oligocene deposits of Cozla, Pietricica, and Cernegura Mountains, collecting over 1000 specimens over ten years. Parenthetically, most of the type specimens from the Piatra-Neamț area as well as numerous additional materials from the Eastern Carpathians were deposited in the paleontological collections of the Natural Sciences Museum of Piatra-Neamţ. Aware of the need to protect fossil sites, Mihai Ciobanu prepares the necessary documentation and proposes the declaration of the Cozla, Pietricica, and Cernegura Mountains as protected areas; today, these mountains are on the list of protected areas of the Romanian Academy holding

the status of of "fossiliferous place" Cozla, Pietricica, Cernegura and Agârcia. The first legislation on the protection of the Cozla fossiliferous site is represented by Decision no. 290/1971 of the Neamț County People's Council. Subsequently, the natural reservation was reconfirmed by the Decision of the Neamț County Council, no. 15 of 23.12.1994, regarding the protected natural areas in Neamț County. The Cozla Paleontological Reservation was registered on the list of protected natural areas of national interest from Law no. 5/2000, Section III - Protected areas - Annex no. 1, point 2.0 code 2.651 and frame, according to OUG no. 154/2008, in category IV IUCN. The paleontological researches carried out during the last years in the area of the Cozla Mountain have led to the identification of two new fossiliferous points, which requires maintaining the current status of the paleontological reservation.

The Neogene depositional area that connected the Caransebeș-Mehadia sub-basin with the Pannonian basin since Badenian (Middle Miocene) is known as the Lugoj sub-basin. The importance of this area is outstanding, firstly from a biostratigraphic viewpoint, because these rocks are rich in transitional faunal assemblages that share representatives from both Central and Eastern Paratethys domains, and secondly, because these fossils are extremely well preserved, allowing fairly detailed studies. An area that could be considered iconic for this sub-basin is situated around Delinești. The fossils described over the years from Delinești are numerous and diverse and include either fish otoliths, or by far much more numerous invertebrates such as: bryozoans, brachiopods, molluscs, ostracods etc. Most of them should now be updated to recent systematics, a problem that is otherwise well known in Romania. The goal of this research is to reclassify some Badenian “annelid” representatives found at Delinești and bring them to the actually correct international systematics, as a first step towards an improved systematic nomenclature for the fossils found this region.

The climate cooldown that occurred at the end of the Eocene

resulted in several turnover events that involved both fauna and flora on the terrestrial and marine realms of Eurasia. These events spread around the Eocene/Oligocene boundary are known as the “Grande Coupure”. In Romania, evidence of these climate cooling results can be found mainly among the Paleogene terrestrial mammal communities, with intruding newcomers of Asian origin. In the marine environments, this time span is challenging for studying the changes that occurred in the biodiversity and distribution of the invertebrate communities. The transgressive tendency recorded in the Transylvanian basin around the Eocene/Oligocene boundary (the Brebi Formation Priabonian portion, until the Pycnodonte gigantica marker level), was followed by the Merian (lowermost Rupelian) deposits (the Merian regional substage: time span between the end of Priabonain and Kiscelian). Recent surveys in the Mera locality revealed an outcrop that could complete the data related to the Berecoaia Valley type section of the Merian, which exposes the Brebi Formation. As a first clue, we discovered a taxon – namely Pycnodonte oligoplana – that is here in described for the first time in the fossil record of Romania, and that has a fossil pearl incrusted in a valve.

Keywords: Sharks, Cenomanian, Mesozoic, South Dobrogea, Romania.

The Cenomanian outcrops belonging to the Peștera

Formation yielded numerous fossil remains of Mesozoic sharks, however due to the environment in which they were deposited, most of the material is fragmented and indeterminable at the species level. Here we report two fossil shark teeth from this formation belonging to Ptychodus mammillaris and Cretalamna sp., based on comparisons with descriptions of similar specimens in published literature. We provide descriptions and discussions based on this material. The aim of this work is to bring to attention new specimens related to Mesozoic sharks, a branch of palaeontology that is still poorly studied in Romania.

Keywords: terrestrial deposits, Maastrichtian, microvertebrates, Transylvanian Basin.

The latest Cretaceous terrestrial deposits that yielded

microvertebrate accumulations are rather scarce in the south-western side of the Transylvania Basin (Metaliferi sedimentary area). In fact, to date, there are only two localities where such fossils were unearthed: Oarda de Jos (with two main sites) and Petreștii de Jos. Recent surveys and field-works carried-out during the spring of 2021 led to the discovery of new terrestrial Maastrichtian sedimentary rocks rich in microvertebrates at Oarda de Jos (Alba County, Romania). Only few dozens of kilograms of the sampled rocks were screen-washed to date, but the results are already very promising. The mudstones hosting the fossils are dark-coloured (grey-blueish), while the bones and teeth are black or dark-brown. This is indicative for an environment of origin with a low content of oxygen, probably an ‘ox-bow’ deposit. Invertebrates are also present, various terrestrial or lacustrine gastropods shells being recovered until now. We preliminarily report here the presence of at least four groups of microvertebrates: theropods, crocodiles, albanerpetontids and fish. Moreover, various egg-shells were recovered (Pseudogeckoolithus in dominance). Besides microvertebrates, there are also macro-fossils. We confirm the presence of sauropods and dortokid turtles in these deposits. The study of these sediments is ongoing, and there are

perspectives that other groups of vertebrates will be added to this assemblage. Based on the available data, we may assume that these remains accumulated in a swamp or small lake, but future work will enlighten our knowledge about the Oarda de Jos Maastrichtian environments.

Keywords: Solar Cycle, geomagnetic storm, planetary geomagnetic indices, wavelet analyses, Fourier analyses.

Based on the planetary geomagnetic indices in the 23rd and

24th Solar Cycles progression, which corresponds to the period 1996-2008 respectively, 2008-2020 we performed some considerations at the beginning of 25th Solar Cycle.

The most important event in this new solar cycle was the geomagnetic storm of May 12, 2021. Based on data from three geomagnetic observatories from INTERMAGNET, we performed Fourier and wavelet analyses.

For this analysis of the geomagnetic data sampled at one minute, we used the North component of each observatory and comparison with physical parameters related with this geomagnetic storm, available on many sites. Also, we used wavelet coherence between observatories, both for the North and East geomagnetic components, for May 12, 2021.

Keywords: gravity anomalies, geomagnetic anomalies, tectonics, volcanic structures.

A vast bibliography is available on the volcanic structures in

Calimani-Gurghiu-Harghita, from which we could extract tectonic and geological information that can be corroborated with geophysical data.

The geomagnetic field maps were built on the data contained in the measurement catalogues in the archives of the Geological Institute of Romania. The data contained in these catalogues is not uniformly distributed, and high-density measuring areas (in areas of interest on valleys and accessible areas) alternate with areas with a very poor coverage (in areas of low interest and areas with a hard-accessible relief), leading to the need for mediations and filters made before interpolation.

The gravimetric maps built on the published data and the data available at the International Gravimetric Bureau were filtered according to mobile mediation procedures and trend surfaces of different degrees.

This paper is a preliminary geophysical and geological study in the project “The realization of 3D geological / geophysical models for the characterization of some areas of economic and scientific interest in Romania”.

Keywords: Flora, Fratoștița, Oltenia, Romania, vegetation.

The flora of Oltenia, so varied and rich, thanks to the site

conditions, has served as an attractive area for a lot of botanists for so many years. Nevertheless, there remained some surfaces which deserve to be studied in order to have a very detailed actual image, referring to the flora and vegetation of this amphitheater ranging from Danube, Olt River and Parâng Mountain. One of these areas is Fratoștița village and the surroundings. The research carried out for five years, has emphasised an area with a richness in flowers and vegetation. From the floristic inventory of the studied area, some rare taxa can be distinguished (Digitalis ferruginea, Cirsium creticum, Hordeum bulbosum, Lathyrus sphaericus), some of them being represented here very well (e.g. Cirsium creticum).

The vegetation from the area of Fratoștița is diversely grouped depending on the diversified site conditions. This highlights the presence of phytocoenosis of some associations Quercetum frainetto – cerris – on the southern, western and eastern slopes, Helleboro odori – Fagetum – along the village and on the north – eastern and north – western slopes and Potentillo micranthae – Quercetum dalechampii on the hills, close to the Turkey oak and Hungarian oak forests.

The meadows are framed at Medicagini minimae – Festucetum valesiacae – on the dry coasts, Agrostietum stoloniferae – in the immediatae vicinity of the slope rivers and Caricetum hirtae subass. cirsietosum cretici – along the slope streams, in the swamps.

Keywords: chorology, Oltenia, vascular plants.

This paper presents some issues related to the chorology of

some vascular plants in the area of Oltenia, on the basis of actual information in the specific literature and on the basis of the practical data on the field too, all collected by the authors of this work. The corroboration of the information from the literature with those from the field has resulted in the reconsideration of the status of these taxa on the territory of Oltenia. For some species, a broadening of the area is observed (e.g. Cirsium creticum), and, on the contrary, for others, we can observe the disappearance from certain stations mentioned in the specific literature (e.g. Rindera umbellata, Plantago maxima), which is explained by the advanced stage of ruderalisation of big areas and by the quick climate changes.

All things considered, we have to take into account that the areas where there are valuable species from a scientific point of view must be protected, and all the required mechanisms must be used to this purpose.

Keywords: biochemical composition, feed value, Onobrychis arenaria, Onobrychis viciifolia, renewable energy.

The aim of this study was to evaluate some agrobiological

features, the quality of fresh mass, hay and residual phytomass after harvesting the seeds of the leguminous species O. arenaria (Kit.) DC. and O. viciifolia Scop., grown in an experimental field of the National Botanical Garden (Institute), Chişinău, Republic of Moldova. In the first year of life, O. arenaria and O. viciifolia were characterized by optimal growth rate and regenerative capacity after being cut, making mowing possible twice per growing season. The productivity reached 2.71-3.15 kg/m2 green mass or 0.69-0.78 kg/m2 dry matter. It was determined that the dry matter content and its biochemical composition varied depending on the species and harvest time: 153-177g/kg CP, 196-231 g/kg CF,112-125 g/kg ash, 248-278 g/kg ADF, 372-412 g/kg NDF, 50-6 g/kg ADL,131-155 g/kg TSS, 192-219 g/kg Cel and 124-140 g/kg HC. The nutritive and energy values of fresh mass fodder: 67.32-69.68 % DDM, RFV=152-184, 10.81-11.16 MJ/kg ME and 6.83-7.15 MJ/kg NEl. The hay prepared from O. arenaria contained 176-179g/kg CP, 266-272 g/kg CF,116-126 g/kg ash, 284-285g/kg ADF, 381-387 g/kg NDF, 45-48 g/kg ADL, 108-109 g/kg TSS, 237-239 g/kg Cel and 97-102 g/kg HC with 66.70-66.78 % DDM, RFV=160-163, 10.7 MJ/kg ME and 6.8 MJ/kg NEl. We found that the fresh mass substrates for anaerobic digestion had C/N=17-20 and optimal amount of lignin and hemicelluloses, the biochemical methane potential of the studied substrates varied from 265 to 289 l/kg ODM. The sainfoin

Keywords: biochemical composition, biomethane potential, Coronilla varia, fodder quality, fresh mass, hay.

This research was aimed at evaluating some agrobiological

peculiarities and the biochemical composition of the harvested fresh mass and hay prepared from a local ecotype of crown vetch, Coronilla varia, grown in monoculture in an experimental field of the National Botanical Garden (Institute), Chişinău, Republic of Moldova. It has been found that the studied local ecotype of crown vetch can be mowed 2-3 times per season starting with the second year of life. The dry matter of harvested plants contains 157-167 g/kg CP, 85-110 g/kg ash, 292-342 g/kg CF, 303-353 g/kg ADF, 450-519 g/kg NDF, 51-58 g/kg ADL; the fodder value is 61.42- 65.30 % DMD, RFV=110-135, 9.95-10.53 MJ/kg ME and 5.97- 6.54 MJ/kg NEl. Crown vetch hay has pleasant smell and contains 160 g/kg CP, 90 g/kg ash, 340 g/kg CF, 349 g/kg ADF, 507 g/kg NDF, 56 g/kg ADL, 61.21 % DMD, RFV=113, 9.93 MJ/kg ME and 6.02 MJ/kg NEl. The substrate of crown vetch fresh mass used for anaerobic digestion is characterized by an optimal carbon-nitrogen ratio – C/N = 18.5-20.2, contains 147-166 g/kg hemicellulose, 51-58 g/kg lignin and the biochemical biomethane potential reaches 281-286 l/kg ODM.

Coronilla varia can be used to re-cultivate permanent grasslands and to establish temporary grasslands in order to prevent soil erosion, in monoculture or associated with other grasses, and the harvested mass can be used as natural feed or hay for ruminants, or as a substrate for the production of biomethane and renewable energy.

Keywords: Lucanus cervus, protected species, population dynamics, nature protection, Transylvania, Romania.

Lucanus cervus (Linnaeus, 1758), known as the stag beetle, is a large Coleoptera species found all over Europe. Due to habitat loss and/or fragmentation, IUCN (International Union for Conservation of Nature) considers it to be “Near Threatened and in need of monitoring”. The purpose of this paper is to bring up-to-date information about the spreading of Lucanus cervus, by signaling its presence in several habitats in the Sibiu and Hunedoara counties as of 2020. The presence of this species this year can also be an important contribution in its monitoring and may be a reference point for researchers who will also address in the future topics related to the area of spread of Lucanus cervus L., 1758. The paper includes information related to the collection site, GPS co-ordinates, collection data, observations related to mating rituals, the number of specimens reported and the ecosystem where the species was observed or captured, in two counties, Sibiu and Hunedoara. Considering the importance of studying this species in Romania, this paper brings new data related to the spread of the species.

In the Miercurea Sibiului Forest District, the study of the

evolution of the pest L. monacha has been a concern for over ten years. During the years 2011-2020, a control system for the population of this pest was implemented and monitored in order to avoid a mass attack. This work is a summary carried out following the centralization of all the collection data of the defoliator Lymantria monacha, produced with ferromonal traps from 2011 to 2020 in the Sibiului forest byte. This forest fund in the county of Sibiu is made up of production units (UP Bistra, UP IV Ciban, UP V Pode) covering an area of 14,911 ha. As a result of the centralization of the collection data from the years 2011 to 2020, 18,663 specimens were taken from the 81 collection points. 2905 specimens were taken in 2020, the highest number in the last ten years, which is why we are proposing to increase the number of ferromonal races and their location, especially in the affected areas, in order to avoid a massive pest attack in 2021.

On 25 October 2020 we studied the diet of two Salamandra

salamandra populations from the Domogled - Valea Cernei National Park. In total, we collected 37 individuals from two habitats, one situated near a brook, and another without a permanent water course. The number of prey taxa consumed in those two habitats was equal (18), as the prey taxa were generally the same in both habitats. The highest percentage abundance and frequency of occurrence was registered for Gastopoda Limacidae. Near the brook, prey taxa related with humidity were dominant. Unlike these, in the other habitat, fire salamanders consumed more preys not related with humidity, smaller in size, with a hard and more chitinous body, which increased the number of preys / individual and food diversity. This indicates that habitat differences (even if both are favourable for S. salamandra) modify the species’ food composition, which, as it is opportunistic, feeds with the more accessible preys in each habitat. Although the study was performed at the end of October, all fire salamanders had stomach contents, and the prey taxa were generally the same consumed in other periods and regions from the country.

Keywords: protected species, tortoise, railway ecology, human impact, habitats, region.

Spur-thighed tortoises (Testudo graeca) are protected in Romania, where they are at the limit of their distribution range. Because tortoises are negatively affected by transportation networks, we supposed that this impact would also be obvious in an area from Romania where they are present. For these, we chose to study the fauna mortality on three railway segments from Dobruja, south-eastern Romania, during the 2020 summer. We identified 75 animals killed on railways, belonging to 20 taxa. Among them, four were tortoises (Testudo graeca). Dead tortoises were identified both between the rails, but also outside them. Thus, it is difficult to know if they were victims of the railway traffic (directly or indirectly) or died from other causes near the railway. We encountered significant railway mortality differences between the studied sectors, probably influenced by the aspect of surrounding habitats. The survey season (summer) and region have a prominent impact on railway wildlife mortality. Many victims were killed long before the study, thus the railway impact upon the fauna may be less severe.

Keywords: probiotics, bifidobacteria, lactobacteria, bacteroids, pathogenic microbes, birds.

The identification of new probiotics as antimicrobial agents

is important in connection with the evolution of antimicrobial resistance of pathogenic bacteria as a result of intensive use of antibiotics. In experiments on gnotobiotic chickens, the ability of monocultures and associations of bifidobacteria, lactobacteria and bacteroids to inhibit and replace pathogenic bacteria – Escherichia and Salmonella was tested. It has been established that monocultures and combinations of useful bacteria in a single dose (1 million bacterial cells for each animal) do not significantly influence the inhibition of pathogenic microbial agents. In order to eliminate them from the intestines, a new scheme was applied, which provided the additional administration of useful bacteria in a dose of 100 billion microbial cells for 15 days, over a day. The administration of beneficial bacteria according to the proposed scheme resulted in the obvious suppression of the pathogens of colibacteriosis and salmonellosis in experimental chickens. Also, the tested microorganisms positively influenced the growth and development of experimental animals and contributed to the general resistance of the organism and protection against gastrointestinal diseases. The obtained results can be applied not only to poultry industry, but also to the captive-breeding of pet and wild birds.

Keywords: woodcock in Romania, synchronized observation, spring migration, non-linear regression.

We have only little information on features of woodcocks’

spring migration in the territory of Romania – apart from certain hunting data. The research method was to count the features of spring migration both in flat and hilly areas on 10 observation stations. We supposed that the number of observed (seen or heard) woodcocks was in proportion with the temporal change of the number of migrating birds, so the temporal alterations of observation numbers would reflect the dynamism of migration. The non-linear regression method was used to model the conformation of the witnessed or heard data and the general observations (n=253). We see that, during spring migration (between the second decadal of February and middle of March), the observed number of birds showed a growing tendency – in varying degrees. On the grounds of our model we calculated the observational maximum and it came out that the peak of migration was on 14th March. The analysis of variance showed a statistically appraisable difference in peaks of migration between the observation points in flatlands and hilly areas. In mountainous areas the peak of migration was on 10th of March whereas on flatlands it was on the 20th of March. It verifies the shift in the process of migration in these different geographical elevation types. In accordance with expectations in the case of seen and heard birds’ numbers we experienced significant differences (p=0.000),

whereas the interaction between the areas and observations was not significant (p=0.135). During the analysis of the relationship between the observations and the observation places we concluded that the number of observed birds is independent from the areas, so there is no significant discrepancy (p=0.461). We must mention that we saw differences between areas in the frequency values, though the experienced frequency distributions can be considered the same in each observation point. It is true that drawing statistically based conclusions on examination of territorial and temporal differences of migration needs a lot of observation data collected through years. Well, the results of our non-representative study with a small item number can be valuable when seeking to expand the knowledge of woodcock migration.

Keywords: bird fauna, migration time, Nature 2000 network, Siret River.

Our ornithological study presents data on the diversity of

bird species recorded during the migration time on the territory of ROSPA0063 Buhuși - Bacău – Berești, starting from May 2011 until May 2020. We identified 172 bird species, part of them being vagrant species with only one or two observations in the area during our study. We also present quantitative data for observed bird species. The typical forest species are dominant by diversity but the aquatic birds present the significant populations. We notice the relevance of this territory for the migration of diurnal raptor bird species, white stork (Ciconia ciconia) and some waterfowl species in the Eastern Romania. We identified 45 bird species that appears in Annex 1 of Birds Directive in the perimeter of Nature 2000 site. We mention the presence of 31 birds species included in the Romanian Red Book of Vertebrates, including four critically endangered species: Pelecanus crispus, Haliaeetus albicilla, Milvus migrans and Sternula albifrons.

Keywords: birds of prey, migration, Mateiaș.

The main aim of this paper was to reveal the amplitude of

the migration of diurnal birds of prey through a pass of the Southern Carpathians, known as the Rucăr-Bran Corridor, although, as we saw, at least a small part of the individuals used a lateral branch of it, on the North-South direction, the Tămaș Corridor. A low passage was discovered at the points of observations centered on the Mateiaș Mountain, situated toward the southern opening of the corridor, 16 species, represented by 645 individuals, being recorded between 2008 and 2020. A few individuals, that were not considered migratory, of other species can be added. However, the study represents only a sample, because of the limited days of survey, and we expect that the real number of individuals that seasonally migrate over the location to be much higher. Differences were seen between the spring migration and the autumn one. Buteo buteo (Linnaeus, 1758) was the dominant species in the spring and Circus aeruginosus (Linnaeus, 1758) in the autumn. Most of the individuals were observed during the week April 2-8, respectively September 24-30 and, as hourly intervals, between 10:00 and 10:59, in spring, respectively between 13:00 and 13:59, in autumn. Their direction of flight was generally on the North-South axis, with deviations depending on the season and species.

The Comparative Anatomy Collection of the “Grigore

Antipa” National Museum of Natural History in Bucharest currently includes over 1700 pieces. The first six pieces were collected by Carol Walstein, director of the museum from 1834 to 1859. In the beginning the collection was named ”Zootomy Collection” and it contained anatomical preparations represented by complete or incomplete skeletons, skulls, various organs preserved in formalin or alcohol. Carlo Ferreratti continued to add preparations to this collection, so more than 76 preparations had been noted in the 1867 catalogue of the Zootomy Collection.

The collection of embryos, vertebrate cubs and hatchlings was donated in 1906 to the Museum of Natural History in Bucharest by Robert Dombrowski. The 66 pieces reunite embryos, foetuses, cubs and chicks from various groups, mammals, birds, reptiles, preserved in formalin and alcohol. Specimens of large vertebrates (fox, wolf, bear) were obtained from various hunters, and the chicks were collected sporadically, during his expeditions in Romania, from predated or abandoned nests, or found dead on the ground. Today this donation is part of the Comparative Anatomy Collection of the “Grigore Antipa” National Museum of Natural History in Bucharest, which currently includes more than 90 specimens preserved in alcohol and another 35 jars with 241 pieces which illustrate the stages of development and growth of different species of reptiles, birds, mammals and invertebrates.

Keywords: Common Pelican, Pelecanus onocrotalus, P. o. roseus?, Bistreț Lake.

The study highlights the role of the Bistreț Lake located

within the Danube Floodplain (southwestern Romania) as an important wetland for Pelecanus onocrotalus, as well as for many other species of aquatic birds. Based on personal observations and specialized literature, we try to contribute to the knowledge of the territorial dynamics of the common pelicans and of the dynamics of the flocks that stop on Bistreț Lake for feeding. In 2020, juvenile specimens of P. onocrotalus appear in large numbers, along with adult specimens. The large number of young specimens (who should have been in their wintering places) and the unusual coloration of some specimens may suggest certain changes in the behaviour and phenology of West Palearctic pelicans, or even the hypothesis, yet undocumented, that among the pelicans present on the Bistreț Lake there might have been present specimens belonging to the African taxon P. o. roseus. Although the explanation regarding the origin of these young pelicans and the mechanism of their occurrence in large numbers can only be drawn up after complex international studies (genetic research, massive ringing, satellite tracking, etc.), it is certain that, for feeding and, implicitly, for the sustainable conservation of this species, the Bistreț Lake is among the wetlands of major importance for the Lower Danube.

Keywords: very warm winter, monthly temperature averages, Hellmann criterion, warm winter phenomena, winter heat waves, vegetative processes.

After the warm and dry autumn of 2020, in which the

secondary maximum of precipitations was registered in October, the winter of 2020-2021 was as a whole very warm (FC) with a general seasonal average of 2.55°C and a deviation from the normal of 3.5°C. December 2020 was warm and exceptionally rainy (EP). January 2021 was warm (C), and from a pluviometric point of view it was excessively rainy (EP). February was warm (C) as a whole and excessively dry (ES), but the water supply in the soil remained almost optimal due to the autumn rainfall and especially the rainfall from December and January. The climatic variability of this winter was particularly high, and global warming continued. Solar activity was close to a minimum and the new solar cycle (25th) began in January 2020. The La Niña climatic process from 2020-2021 peaked in October-December 2020 as an event of moderate intensity. The latest forecasts from the WMO World Center for Long-Term Forecasts indicate a moderate probability (65%) that La Niña climatic process will continue in February-April. At the level of Oltenia, the winter of 2020-2021 was the fourth warmest winter in the history of climatic records so far with a seasonal average of 2.55°C, the first being 2006-2007 (with an average of 3.44°C), the second 2019-2020 (with an average of 2.89°C), and the third 2015-2016 (with an average of 2.88°C). The paper is part of an extensive series of studies on climate variability in southwestern Romania and climate change at the regional level and is useful to all those interested in climate issues and its evolution in this part of Romania.

Keywords: biohydrometallurgy, platinum metals, acidophilic chemolithotrophic bacteria, Romania.

The potential enzyme evaluation of the acidophilic,

chemolitotrophic and heterotrophic bacteria specific to the mining biotope is of high interest in the solubilization, recovery and / or removal of platinum metals from industrial waste car tires. The obtained data show that the formation of extracellular polymeric substances plays an important role in the attachment of the chemolithotrophic bacteria on the surface of minerals, as well as sulphur. In this sense, a direct interaction between the bacterial cells and the solid surface is mandatory for an efficient mobilization of platinum metals from waste car tires. These occur at two levels: (a) physical sorption due to electrostatic forces with low pH in the leaching media; (b) chemical sorption is carried out only in the type of chemical bonds between the bacterial cell disulphide bond and minerals. The optimization of the technological process such as solubilization and the recovery of platinum metal ions contained in ferrous and non-ferrous industrial waste was materialized through a series of laboratory experiments based mainly on the affinity of bacterial cells for certain organic and / or inorganic surfaces. It is based on the results of the physical-chemical characterization of the liquid samples taken. This study deals with the optimization of the solubilization process of metal ions contained in such samples.

Keywords: microorganisms, noble metals, bacterial oxidation, enzymatic reduction, Romania.

The development of processes based on the activity of

micro-organisms is very important to increase the efficiency of processes for the recovery of noble metals from industrial wastes by two beneficial effects: (1) the bioremediation of polluted environment with inorganic waste, such as heavy metals that are toxic to most forms of life, including humans; (2) recovering the amounts of metal ions in order to reuse them for the economic purpose. The evolution of technology, the deepening of the knowledge of the microbial diversity and the action of the microorganisms on the different natural substrates allowed the realization of some economic technological processes. Among them, the use of microbiological methods for the recovery of noble metals from industrial wastes presents a particular importance due to the depletion of rich ore stocks, as well as the accumulation of waste poor in metals due to their processing by hydrometallurgical methods. The biodegradative action of microorganisms is the result of the alternative intervention by heterotrophic and chemolithotrophic bacteria in a positive sense in the economy of human society.

Keywords: coal, inorganic sulphur, bacterial oxidation, ecological valence, Oltenia.

The enhanced environmental pollution determined the

increase of the interest regarding microbial resistance to heavy metal ions and especially on the extension of the potential of biotechnological applications of acidophilic microorganisms. Physical methods for coal desulfurization, developed nationally and internationally, involve the separation of pyrite (FeS2) from coal, by means of flotation processes, hydrogravitational processes, and magnetic separation. The case study was conducted for crude coal taken from mining operations in the Valea Jiului coal basin, Romania. In order to determine the content of granulometric class less than 1 mm, analyses were performed for coal from the Vulcan, Lupeni, Lonea, Paroşeni and Petrila mines. The distribution of sulphur on densiometric fractions for coal in the Jiu Valley is on average 1.9% and different in coal fractions, for example: 2.65% for densiometric fractions -1.36 t / m3, 1.36 ÷ 1.73 t / m3 1.19% for the densiometric fractions 1.73 ÷ 2.2 t / m3 and +2.2 t / m3. The physical processes for removing inorganic sulphur from coal are(1) ׃ the concentration in the hydrogravitational field - sulphur extraction was

25 ÷ 30% in the concentrate and mixtures resulting from the separation, with the Gemini mass. Also, there was an improvement in the quality of coal, by increasing the ppc content in the table waste, but also a loss of coal in the mixture from gravitational separation, up to 15% ÷ 20%; (2) separation in magnetic field – the content of sulphur in the magnetic product, extracted with the lift magnet separator, for mining exploitation perimeters, was: 11.48% Lupeni; 8.34% Paroşeni; 6.4% Vulcan; 5.85% Lonea and 3.09% Petrila; and the sulphur content in the non-magnetic product (76-94%) was: 1.14% Petrila, 1.12% Lonea, 0.57% Vulcan, 0.51% Paroşeni and 0.48% Lupeni. In the non-magnetic product (desulfurized coal) there is still 40-54% sulphur existing in the original coal, which means that sulphur is not only related to pyrite, but also to sulphates without magnetic properties. In the bacterial desulfurization experiments of coal by bacterial cultures of Acidithiobacillus ferrooxidans, two types of coal were used: (1) coal from Lupeni and (2) lignite from Turceni. In order to study the increase in the yield of the bacterial oxidation process of inorganic sulphur from coal, the experiments were accompanied by chemical and biological controls. At the end of the experimentation period, the weight loss of coal under the action of A. ferrooxidans cultures was determined, which solubilizes pyrite by transforming ferrous iron from sulphide into soluble ferric sulphate. Also, for the treated coal samples, the amount of inorganic sulphur was determined by the gravimetric method with BaSO4, at the chemistry laboratory from the National Research-Development Institute for Metals and Radioactive Resources.

Keywords: Turceni and Rovinari Energy Complexes, environmental protection, energy blocks, water quality.

The present study consisted in monitoring the Turceni and

Rovinari Energy Complexes, consisting of thermal energy blocks with very high installed capacity - 330 MW, which operate on lignite fuel. These blocks are located on the bank of the Jiu River, near the coal mines. Due to this technological process that pollutes the water, we monitored some of the physico-chemical parameters of the captured and discharged water, establishing that temperature is the most affected factor with implications on the ecosystems of the Jiu River. The evolution of the temperature in the operating system - open circuit - affects the Jiu waters at the maximum allowable limit. The monitoring of the physico-chemical parameters, especially of the temperature, determines the diminution of the thermal effects on the waters of the Jiu River, respectively the maintenance of an unpolluted fauna and flora. The electric energy produced by the thermoenergetical blocks is 65%. A feature of these energy complexes is the use of the Jiu River for both water capture and discharge. If the energy groups worked at full capacity, the technological waters discharged into the Jiu River would be heavily polluted, affecting flora and fauna.

Research conducted in lake ecosystems representative of the

Romanian territory of the Oltenia Plain has highlighted the fact that invertebrate species make up populations with high numerical densities and biomass. The phytophilic fauna is dominated by the larvae of chironomids, coleoptera, ephemeroptera, heteroptera, gastropods. In the areas near the banks, where the facies is composed of plant detritus and mud, there are a large number of chironomids, ephemeroptera, plecoptera, oligochaetes and gastropods. A smaller diversity of benthic invertebrates has been observed in deep areas where the facies is sandy-muddy. Numerous protozoa, gastropods, tendiped larvae, trichoptera, odonata, chironomids and gamarids have been identified in areas abundant in macrophytes and plant detritus. Under current conditions, an important role in the biological production of lake ecosystems in the lower Jiu sector is played by populations of gastropods, predominantly benthic organisms that actively respond to the heterogeneity of the microhabitats they populate. Following research conducted on 16 species of gastropods identified in lakes, depending on biomass, it was found that the

largest share belongs to the populations of Viviparus acerosus, Lymnaea stagnalis, Stagnicola palustris, Radix balthica and Planorbarius corneus, between 147 g / m2 and 649 g / m2. Also, the performed studies showed the increased tolerance of the lung snail species Radix balthica, Lymnaea stagnalis, Planorbarius corneus to the presence in the environment of bivalent metal ions coming from the industrial activities of solid waste processing. These species are bio-indicators of contaminated environments in the industrial sector of the lower Jiu, due to early signals of emergence of negative changes in lake ecosystems. According to the above considerations, selected Acidithiobacillus ferrooxidans chemolithotrophic bacteria with a high tolerance to high concentrations of iron, copper and zinc may be used in the solubilization of sulphur ores (pyrite, arsenopyrite) from gold concentrates, especially those refractory to classic cyanide processes Also, acidophilic heterotrophic bacteria of the Acidiphilium genus and yeasts, with increased resistance to copper, zinc, nickel and chromium will be able to be used with increased efficiency for the depollution of residual liquid effluents and sediments with high concentrations of heavy metals. The results regarding the effect of physico-chemical factors on the growth and oxidation / reduction capacity of some compounds specific to acidophilic microorganisms led to the establishment of optimal growth and activity parameters, as well as the identification of populations of interest for further experiments. Also, the obtained results demonstrated the superiority of the removal efficiency of metal ions in the conditions of using acidophilic microorganisms, heterotrophic bacteria of the Acidiphilium genus and yeasts. These experiments performed in laboratory conditions allowed to compile a collection of acidophilic microorganisms, chemolitoautotrophic and chemoorganotrophic, with important properties in terms of involvement in technological processes of recovery / removal of metal ions from harsh environments.

The limnological peculiarities of the dam lakes are largely

dependent on the pulsating character of the stationary water circulation, as well as on the economic needs. The ecological balance of the Olt River in the lower sector was drastically affected after the arrangement, there were a number of changes in the morphology of the riverbed and river banks, as well as important changes in the flow of surface and groundwater, soil cover and biotic environment. All these have led to profound changes in the structure of aquatic biocenoses, by reducing some populations to the limit of survival, replacing rheophilic populations with pelophilic, pelophytophilic or phytophilic populations, or even leading to the disappearance of some species, the most affected being the benthic and nectonic fauna. The complex development of the Olt River determined its structural and functional characteristics. The structures of biotopes and biocenoses are specific to both typical rheophilic and stagnophilic ecosystems. In accordance with the determined characteristics of the arrangement, all the specific ecological compartments (planktonic and benthic) can be identified in the structure of the biocenoses. Benthic fauna is represented by 10 groups of invertebrates, dominated by oligochaetes, bivalves, chironomides, gastropods. Gastropods have an important role in the transfer of matter and energy to higher consumers - fish.

The IOR Lake is located in the eastern part of Bucharest, in

the Alexandru Ioan Cuza Park of the 3rd district and, based on the available data, is considered a lake of artificial origin, anthropogenic, resulting from the extraction of construction materials from its current perimeter. In relation to the water supply sources, they are included in the category of lakes fed by precipitation (rains, melting snow) but also through some underground springs, having a variable depth. The quality of the lake water is influenced by the organic and inorganic material leached from the slopes that border it, the organic matter accumulated in the sediment, the vegetation that develops on the shores and the presence of economic units (terraces, restaurants, food outlets, etc.). Between October 2020 and April 2021, the colour of the lake water presented a brickish appearance throughout the table, which decreases in intensity in small volumes of water (1-2 litres). The purpose of the obtained analyses and results, as presented in this paper, was to establish a possible cause of this phenomenon. The obtained results showed the presence of mesophilic aerobic heterotrophic bacteria. Of all coliforms in all water samples, colonies characterized by the presence of E. coli bacterium, of fecal steptococci and the absence of total coliforms are highlighted. Colonies of ferrobacteria have been identified and from a chemical point of view the presence of iron oxides in larger quantities is noticeable. Physico-chemical data were within normal values.

Endolytic habitats are characterized by a diversity and

abundance of microorganisms that show their ability to accumulate energy from substrates of different nature, organic or inorganic, and the ability to grow in a wide range of natural conditions. The present paper refers to an integral approach of the distribution of microorganisms in the analysed field and of the characterization of the investigated habitats in subsequent conditions. The most widespread forms of endolytic communities colonize gaps, cracks, fissures (being called cosmoendolytic) or porous spaces in the mineral structure (the so-called cryptoendolytic). Preliminary results show a high diversity of such microorganisms in the two categories of volcanic tuff studied but also the presence of a wide spectrum of extracellular hydrolases that allow the microorganisms to survive in these extreme conditions.

A range of economic agents of different industrial importance but also a range of residential complexes with high anthropogenic impact on the river waters are established along the river. This paper addresses some aspects of pollution in the perimeter between the Dimieni Bridge and the Tunari Dam, with sampling points established at the beginning and at the end of the perimeter. The results obtained during four sampling campaigns covering the four seasons showed some changes from the normal parameters specific to unpolluted flowing water. Also, the analysis of the chemical composition by WD-XRF spectrometers shows a different content in the two sampling points, with significant amounts of barium oxide being noticed in the cold temperature seasons.

Keywords: invertebrates, gastropods, Tinca, Romania.

The observations presented in this paper are the result of

research conducted in terrestrial ecosystems representative of north-western Romania, the Tinca area, from the south-western Bihor County. The invertebrate fauna of the area is varied, being represented by molluscs, myriapods, spiders, insects and gastropod molluscs, which have an important role in trophic relationships, constituting a factor of accumulation of mass and energy to higher consumers. 27 species were identified, the dominant ones being those belonging to families Clausilidae, Limacidae, Helicidae. The main determinants of the distribution of gastropod species are soil characteristics and vegetation type. The analysis of the age structure highlighted the fact that most species are dominated by breeding and pre-breeding individuals, which demonstrates a growth tendency of the population. Following the analysis of the chemical composition of the shells of Helix pomatia, the presence of radioactive metals was not revealed, which proves that the Tinca area is not polluted from this point of view.

The paper presents studies on predatory mites realized in Romania. The method used for highlighting the subject is a comprehensive literature survey. We concluded that studies performed before 2006 provided scarce information about the ecology of predator soil mite communities from different types of ecosystems, highlighting mostly the taxonomical aspects. Later studies provided information about the ecology of the predator soil mite populations from different types of terrestrial ecosystems (shrubs, cliffs, urban, grasslands, etc), and about the correlations between these invertebrates and different environmental variables from natural or anthropic areas from Romania.

This review analyses the interactions of lichens with in the

ex vitro and in vitro environment, with an emphasis on structural and functional features, and factors that sustain their favourable evolution in the context of disturbance of certain parameters. An extensive bibliography highlights the lichens’ tolerance to desiccation, heavy metals accumulation from polluted environment, cryoprotection mechanisms, by inducing repair mechanism as secondary metabolites production. The in vitro conservation of lichens is an efficient alternative reproduction strategy in the context of environmental changes and offers the possibility to understand this type of close symbiosis by promoting new studies of interactions between symbionts.

Keywords: endophyte, Ensifer sp., bitter melon, root-knot nematode.

Endophytes are plant-associated microorganisms adapted to

live inside plant tissues without causing harms to their hosts. Genomic studies showed that plant tissues, especially roots, are colonized by a wide spectrum of endophytic bacteria. Symbiotic associations are mediated by complex molecules released both by the plant and microorganisms. Such natural mechanism is already known in the endophytic association of rhizobia with compatible leguminous plants. Although host specificity for rhizobia is a known aspect, in nature, particular cases can be found. Indirect endophytic association can be possible when third parties are involved. Particular endophyte colonization can be found among symbiotic rhizobial-like bacteria and atypical host plants. This paper presents a particular case of endophytic association between bacteria of the genus Ensifer and the roots of Momordica charantia plants. The access of these bacteria to the plant is considered to be mediated by the attack of bitter melon caused by the root-knot nematode.

In recent years, the Natural Sciences Museum Complex of Constanta has received numerous specimens of birds of prey: red-footed falcon (Falco vespertinus), Eurasian hobby (F. subbuteo), long-eared owl (Asio sp), common buzzard (Buteo buteo), etc.). Excluding natural causes, many specimens are orphaned chicks, fallen from nests, but we also have specimens of birds electrocuted on power lines or that have suffered collisions with cars. Given the increased number of such specimens arriving in our institution, our activity aims at raising the public’s awareness of the role of living heritage museums as well as zoos, in rescuing, treating and, where possible, reintroducing those animals into their natural environment, thus contributing to educating the general public on how to act when they find such wild animals in difficulty, but also on what rehabilitation work means.

Keywords: Bacillus subtilis, biocontrol, Fusarium, sweet potato.

The sweet potato, Ipomoea batatas (L.) Lam., is a highly

productive crop, successfully acclimatized in Romania. Worldwide, in countries where sweet potato is a traditional crop, a wide range of plant pathogens is mentioned. In Romania, a few phytopathogenic infections have been encountered for this culture. However, the incidence of Fusarium on sweet potato increased in the last years. In the present paper the symptomatology of sweet potato fusariosis is described. The aim of the study is to reveal the biocontrol potential of a Romanian native strain of Bacillus subtilis in reducing Fusarium spp. growth. Bacterial physiologic studies have shown that the strain uses several mechanisms to inhibit fungal growth. In vitro tests showed an efficiency of 31.3 to 51.4% for the inhibition of the growth of phytopathogenic fusaria.

The paper presents the results of studies on attraction of

Heteroptera towards two types of light traps – ultraviolet and white during 2012-2020. In total, more than 31,000 bugs were caught, belonging to 151 species from 15 families, of which three are prevalent – Corixidae, Miridae and Anthocoridae. The terrestrial heteroptera from the family Miridae and Lygaeidae were almost equally attracted by white and ultraviolet light – the ratio of caught bugs in traps was 1:1.2-1.6, respectively. On the other hand, aquatic (family Corixidae) and palustre (family Saldidae) heteroptera in 2.4-2.6 prevail in the trap with ultraviolet light, compared with white, and predatory heteroptera from family Anthocoridae were more numerous (2.4 times) in traps with white light. Twenty-one species present in all years of investigations make up 13.9 % of the list of species recorded and the majority (93.8 %) of the total specimens captured. Thirty-nine species of heteroptera were attracted exclusively by ultraviolet light, and only 15 species flew in white light, both groups accumulating only 1-7 specimens during the entire research period.

Few data are available on the diet of the juvenile Pharaoh Eagle

Owl in North Africa. The diet of the juvenile Pharaoh Eagle Owl was analysed in a semi-arid environment in Djbel Tarf (Oum El Bouaghi) which is located in the North-Eastern part of Algeria, through the analysis of 93 pellets of juveniles that were collected from the same nest during the breeding period (spring) during three successive years of study (2016, 2017, and 2018). The trophic menu of the juvenile Pharaoh eagle-owl in the region of Oum El Bouaghi is composed of 5 prey categories with a relative abundance of mammals occupying the first rank during the three successive years (43.48%, 47.47%, and 41.54%); followed by insects (29.23%, 28.09%, and 26.70%) and birds (15.70%, 13.76%, and 14.49%). In terms of relative biomass, lagomorphs (Lepus sp., 35% ≤ B % ≤ 51%) were the main prey species, while birds (Columbidae sp., 17% ≤ B % ≤ 23%) were the second most important prey species. In terms of abundance, the dominant prey species was Meriones shawi for the three years of study with 14.49%, 14.33%, and 12.22% respectively. It was followed by Jaculus orientalis (8.70% ≤ AR % ≤ 11.80%), Gerbillus campestris (8.45% ≤ AR % ≤ 11.24%); Oryctes nasicornis (6.11% ≤ AR % ≤ 8.45%); Tapinoma sp.

The Șura Mare Cave is part of the karst complex located in South-Western Romania, which contains the most important (winter) shelters for bats. These caves are considered one of Europe’s major chiropteran hot spots. The Șura Mare Cave has some peculiarities: it is a fully active cave, it is located in a difficult gorge (limiting speleotourism), and has an opening height of 42 m and a length of over 13 km. This cave shelters one of the largest hibernacula in Europe (about 120,000 specimens), including 11 identified species: Pipistrellus pipistrellus (63,000 specimens / 19.12.2009), Miniopterus schreibersii (50,200 specimens / 14.02.2010), Myotis myotis, M. oxygnathus, M. daubentonii, M. nattereri, Rhinolophus ferrumequinum, R. hipposideros, Barbastella barbastellus and Nyctalus noctula. This paper presents the results of over 17 years of monitoring. This cave also shelters one of the few Nyctalus noctula cave hibernation colonies in Romania, about 850 specimens. The cave also houses a mixed nursery colony, consisting of 1000 M. myotis/oxygnathus individuals (02.06.2015) and 200 M. schreibersii individuals. This bat shelter has attracted both Romanian and foreign speleologists and chiropterologists, as early as the 1950s. The colonies are less vulnerable due to their cluster locations, at heights of 15-35 m. It is worth noting that there is a remarkable multiannual stability of ecological conditions in the cave and in its vicinity, as the size of the hibernaculum has been quasi-constant in the last 60 years.

The research aimed at isolating and examining the

Trichinella spp. larvae from samples of muscle tissue collected from wild animals from the forest environment in the Dolj County (Radovan Forest): fox Vulpes vulpes (Linnaeus, 1758), (2 samples), wild boar Sus scrofa (Linnaeus, 1758), and common rat Rattus norvegicus (Berkenhout, 1769) (a sample).

The experiments were performed using the equipment and apparatus of the parasitology laboratory within the L.S.V.S.A – Dolj, by two methods: the artificial digestion method and the Trichinella spp. parasite detection method by trichinelloscopic examination. Trichinelloscopic examination allows the differentiation of Trichinella and Sarcocystis cysts, the latter being arranged among the muscle fibers not being delimited by fibrillar layers that form a secondary cystic wall.

The distribution of Trichinella spp. parasite globally is wide, including in the Arctic, temperate and tropical countries. The disease was reported in 1999 in other species of wild animals raised in captivity: Panthera leo (Linnaeus, 1758) – The Zoo from the "Nicolae Romanescu" Park in Craiova, and the causes that led to the death of the animal were frequent feeding with infested horse meat.

Keywords: mineral premix, calves, resistance, adaptation.

The main task of digestion physiology in animals is to

maintain body's homeostasis within normal limits, which is possible by determining the type of influence of the food factor on homeostasis, development and realisation of the genetic potential of animals. This paper presents the mineral premix testing results made at the Institute of Physiology and Sanocreatology of the Republic of Moldova on some indices of calves’ metabolism in postnatal ontogenesis for determining the parameters that can condition the resistance and adaptive capacities of animals against environmental action and the acceleration of fore-stomach functionality formation. When supplementing the food ratio with ”PMVS”, by using physiological, biochemical and microbiological methods in the dynamics of age periodization (7, 30, 60, 90 days) of calves in the experimental researches, original data was obtained referring to the functional condition, resistance and adaptive capacities of the body. The elaborated premix stimulated the functional formation of the rumen, which was seen in the development of fermentation processes. A positive effect of calcium, phosphorus and their ratio was found, which indicates a moderate intensification of the metabolism of macroelements. The enhanced adaptive capacities of the body and the optimal maintaining of osmotic balance of extracellular and interstitial fluid were influenced by the K+ and Na+ properties of premix. The microelements (Fe2+, Cu2 + and Zn2+) influenced the composition of oxidoreduction ferments, thus contributing to the prophylaxis of anaemia and increasing the immunological reactivity and the body weight of calves. During the

experimental period, changes were recorded in the metabolism of proteins and protein fractions expressed by the reduction of content of proteins and redistribution of their fractions. The enhanced biological value of the ratio, by including the mineral premix “PMVS”, had a positive impact on the cellular and humoral link of the natural resistance of animals in early postnatal ontogenesis.

Keywords: stress, antioxidant, reproductive cells, cryopreservation.

The reproductive system is permanently subjected to the

action of a number of factors, which influence it positively or negatively. Therefore, the purpose of the research whose results are presented in this paper was the study of the influence of oxidative and nociceptive stress on semen and the reproductive system of breeder bulls and estimating the possibility of diminishing the consequences of the influence of these factors. In order to achieve the proposed purpose, microscopic, physiological, biochemical and statistical methods were used. These research methods enabled to determine that during the technological stages of preservation and cryopreservation of the bull sperm, the oxidative stress of spermatozoa causing morphological changes and decreasing the indices which characterize the functional state of reproductive cells takes place. In the case of the animals’ nociceptive stress, a spermatogenesis disorder occurs, which is expressed by the tendency of spermatozoa to develop in the typical or atypical direction. Also, under the stress, the indices which characterize the functional state of spermatozoa (mobility and longevity) are decreased, and antioxidants of natural provenance can be used to reduce the negative consequences of stress. The research results have shown the action of stress at the technological stages of cryopreservation of semen and the fact that oxidative stress is one of the essential deteriorating factors in the process of sperm cryopreservation; the animals’ nociceptive stress negatively influences the spermatogenesis process

Keywords: Metarhizium anisopliae, fifth instar larvae Schistocerca gregaria, biological control.

The desert locust is potentially the most dangerous of agriculture, because of the ability of swarms to fly rapidly across great distances. The locust control strategy has so far mainly consisted of the application of synthetic insecticides, which can be harmful to the environment. Therefore, research institutes are turning to other methods, including biological control, particularly microbiological control in its various forms, to try to control swarming locusts. Due to its persistence in the soil and its harmlessness to humans and animals and in the context of biological control, we tested an entomopathogenic fungus Metarhizium anisopliae on fifth instar larvae of the locust Schistocerca gregaria (Forskål 1775). Preliminary tests have been done in the laboratory on locust larvae. Cryptogam was administered by direct spraying on the treated individuals, and three doses were used, namely: D1 =1,46x107

spores/ml, D2= 1,46x106 spores/ml, D3= 1,46x105 spores/ml. At the same time, the witness was sprayed with sterilized distilled water. We obtained 100% mortality between the 6th and the 8th day of treatment. Therefore, no mortality was observed in the control. In parallel, moulting disruption was observed preventing the larvae to become adult.

Keywords: peat bog, flora, vegetal associations, Valea Rea bucket, Făgăraș Massif.

The south-eastern Carpathian peat bogs are a widespread

habitat in the subalpine floor of the Făgăraș Mountains. They are found in the area of glacial lakes and on valleys and slopes near the streams. On the smooth plateau with excess moisture of the Valea Rea there is a peat bog on an area of about 1 ha. Located at the base of Viștea Mare and Moldoveanu peaks, the Valea Rea Bucket, modulated by glaciers that dug into the rock of the mountain, sheltered a plateau on which the place of gravel is taken by a swamp area with the appearance of a small delta, with an area of about one square kilometre and several small lakes and islands of vegetation. On the left, the Valea Rea Bucket is guarded by Galbena Mountain and Roșu Peak (2465 m), on the right by the Valea Rea Edge and in front by the Viştea Mare (2527 m) and Moldoveanu (2544) Massive, Moldoveanu being the highest peak in the country. Under the Moldoveanu peak there is a large lake, the Triangular Lake of Moldoveanu, which received this name due to its shape. Located at 2159 m altitude it is located at the top of the glacial bucket and is fed by underground springs. From the Triangular Lake of Moldoveanu (Iezerul Moldoveanu) the water flows through the Budurile Văii Rele, in the most spectacular waterfalls in this area, to the Valea Rea stream, the main tributary of the Doamnei River.
