Introduction

Previous studies on amphibians and reptiles in Ceará, northeastern Brazil, have focused on the Caatinga and relictual tropical rainforests (“Brejos de Altitude”) (e.g., Borges-Nojosa et al., 2010; Loebmann and Haddad, 2010; Ribeiro et al., 2012). The lack of studies on the coastal zone is illustrated by the fact that some large reptiles with apparently stable populations (Eunectes murinus and Paleosuchus palpebrosus; Mendonça et al., 2009; Lima et al., 2011), which are well known to the locals, have been only officially reported recently.

The state of Ceará has about four phytophysiognomies: Atlantic rainforest, Caatinga, Cerrado and Coastal

vegetation complex (Figueiredo, 1997). Although studies involving herpetofauna of Ceará started around the nineteenth century (Lopes and Silva, 2003), not all of these physiognomies were fully prospected. Specifically, the coastal region has been poorly investigated, with only a general study, which only reports some species of the Coastal region, without providing a list (Cascon and Borges-Nojosa, 2003).

The Northeast Coast of Ceará has a warm and dry climate. Its closeness to both the Cerrado and Caatinga allows the occurrence of species from these two domains, forming a vegetation complex (Castro et al., 2012). Both are savanna formations with shrubs and two well-defined seasons (dry and rainy; Coutinho, 2006). Additionally, rain forest areas nearby could also influence this vegetation complex.

The coastal area of the city of São Gonçalo do Amarante, Ceará, has been subject to land speculation and is being developed into a Port and Industrial Complex. This enterprise is contributing to rapid changes in local conditions and may cause a strong impact on local wildlife. Given the lack of research in the area, it is difficult to propose a management plan for the conservation of local fauna. As a result, an available list of the herpetofauna of this coastal area in Ceará is lacking.

Here, we surveyed amphibians and reptiles of the coastal region of São Gonçalo do Amarante, reported geographic distribution extension for some species found in the area and tested their similarity with other

Abstract. We surveyed amphibians and reptiles in São Gonçalo do Amarante, Ceará, Northeastern Brazil, from December 2007 to May 2009. We recorded 23 species of amphibians from six families and 37 species of reptiles from 15 families (one amphisbaenid, one freshwater turtle, 14 lizards and 21 snakes). The distributions of Scinax nebulosus and S. fuscomarginatus were expanded to the coastal region of Ceará. Species accumulation curves for reptiles and amphibians reached an asymptote. Richness estimators predicted 25 species of amphibians and 42 of reptiles. The herpetofauna of the study area is very similar to that of Caatinga areas of Ceará and is less similar to that of nearby areas of Atlantic rainforest.

physiognomies of Ceará. We compare the study area with surveys in Ceará in order to make a general characterisation of the diversity of this coastal region in comparison to nearby areas.

Material and Methods

Study area

São Gonçalo do Amarante, Ceará, Brazil has an area of 834.39 km², and the predominant vegetation is semi-deciduous coastal forest (Figueiredo, 1997). The study area includes floristic elements of Caatinga, Cerrado, and Restinga, corroborating the idea that the plant community of the coastal region of Ceará has an ecotonal nature (Castro et al., 2012). The mean annual maximum temperature is 28 °C and minimum is 26°C, and the mean annual rainfall is 1,026 mm, mainly concentrated from January to June (FUNCEME, 2014).

Sampling occurred in three sites (Figure 1 and 2) chosen randomly with similar vegetation and climate: Dunas (-3.545527°, -38.857833°; 7 m a.s.l. hereafter datum WGS84), Jardim Botânico (-3.574194°, -38.888694°; 28 m a.s.l.), and Taíba (-3.515250°, -38.918805°; 13 m a.s.l.).

Data collection

We conducted fieldwork during 18 months, four days per month, from December 2007 to May 2009. In December 2007 and in April 2008, the effort was greater with two sampling periods of four days in each of these months.

Specimens were collected using five stations of pitfall traps with drift fences in each sampling site (Cechin and Martins, 2000; Heyer et al., 2001), consisting of four 60-L plastic buckets, disposed in a “Y” arrangement in each station. This methodology was applied in each sampling site, totaling 15 traps/day. We also used time-constrained searches (transects; Heyer et al., 2001) lasting one hour in an area of 600 m² during the daytime, totaling 108 person/hours of sampling effort. We used unlimited active search at night near lakes (Heyer et al., 2001).

Voucher specimens were euthanised by injection of lidocaine hydrochlorid, fixed in 10% formalin and preserved in 70% ethanol (Auricchio and Salomão, 2002). Specimens were deposited in the Coleção de Herpetologia da Universidade Federal do Ceará

(CHUFC; Appendix 1). Nomenclature followed Frost (2014) for amphibians and Uetz (2014) for reptiles.

Data analysis

We built species accumulation curves separately for amphibians and reptiles to analyse monthly sampling effort (Gotelli and Colwell, 2001). These curves were based in the Mao Tau’s method for species accumulation in the software EstimateS (version 8.0.0) (Colwell, 2006), with a confidence interval of 95%. The richness of amphibians and reptiles was estimated with the first-order Jackknife.

We compared the herpetofauna of São Gonçalo do Amarante with data from other physiognomies (Caatinga, Cerrado and Brejos-de-altitude) from the state of Ceará with Jaccard’s Similarity Index and represented using the UPGMA clustering method. The herpetofauna of Caatinga areas were obtained from

Borges-Nojosa and Cascon (2005), Borges-Nojosa et al. (2010), Loebmann and Haddad (2010) and Ribeiro et al. (2012); Brejos-de-altitude from Borges-Nojosa (2007), Loebmann and Haddad (2010) and Ribeiro et al. (2012); and Cerrado from Loebmann and Haddad (2010) and Ribeiro et al. (2012). The herpetofauna of Serra da Ibiapaba (Loebmann and Haddad, 2010) and Chapada do Araripe (Ribeiro et al., 2012) were divided in those three physiognomies according to information presented in these papers. We did not include unidentified or introduced species. These analyses were made using the free software Past v. 2.10 (Hammer et al., 2001).

Results

We recorded 23 species of anurans from six families (Table 1), 36 species of squamate from 14 families and one species of chelonian (Table 2). Accumulation curves based on monthly sampling effort (Figure 3 and

Figure 2. Study areas A- Taíba; B- Dunas; and C- Jardim Botânico.

4) showed that the richness of amphibians and reptiles reached an asymptote. The richness estimator predicted 25 species of amphibians (Jackknife = 25.85 ± 2.08) and 42 of reptiles (Jackknife = 42.7 ± 2.79), considering chelonians and squamates as one group.

The herpetofauna of the study area is very similar to that of Caatinga areas of Ceará (Figure 5 and 6) and most likely represents a mixture of species from these three physiognomies, Caatinga, Cerrado and rainforest. The study area is more similar to distant Caatinga areas, such as Serra da Ibiapaba and Chapada do Araripe than to nearby areas of rainforest such as Serra de Baturité. It is also different from the Cerrado areas of Serra da Ibiapaba and Chapada do Araripe.

Discussion

The study area has species broadly distributed over Ceará such as Tropidurus hispidus, Ameiva ameiva, Rhinella jimi, which were found in all physiognomies. Ameivula ocellifera, Salvator merianae, Iguana iguana, Rhinella granulosa, Leptodactylus vastus, Leptodactylus macrosternum and Proceratophrys cristiceps were also present in almost all physiognomies in Ceará.

Anurans recorded in the studied area, in general, were generalist species regarding habitat use, and most of the species were typical of Caatinga areas (Arzabe, 1999; Borges-Nojosa et al., 2010; Loebmann and Haddad, 2010; Ribeiro et al., 2012). The reptiles, in general, also were habitat generalists, and were also representatives of the Caatinga herpetofauna (Rodrigues, 2003; Borges-Nojosa et al., 2010).

Herpetofauna of a coastal region of northeastern Brazil 409

The distribution of Scinax nebulosus and S. fuscomarginatus were extended to the coastal region of Ceará. Despite being described as widely distributed (Peters and Orejas-Miranda, 1970), Mastigodryas bifossatus was recorded for Ceará in only two studies (Lima-Verde and Cascon, 1990; Mesquita et al., 2013). According to national (MMA, 2014) and international (IUCN, 2014) lists of endangered species, no endangered species were found in this study.

Previously, the coastal region of Ceará was classified as physiognomically distinct from Caatinga (Fernandes, 1990; Figueiredo, 1997), but recently it has been suggested that its flora has ecotonal characteristics that include species from Cerrado and Caatinga (Castro et al., 2012). Our comparisons of similarity index and cluster analyses indicate a similarity between the study area and Caatinga and reinforce the ecotonal view of the Vegetational Complex of Ceará which has amphibians and reptiles found in Caatinga, Cerrado and Rainforest areas (see Table 1 and 2, and Figures 5 and 6). The higher similarity between the herpetofauna of the study area and distant Caatinga regions than to nearby areas of Brejos de Altitude suggest that physiognomies have higher influence in similarities between herpetofauna of different areas than geographic distance.

To conclude, the herpetofauna of the study area is similar to Caatinga areas, but it also shares species with Rainforest and Cerrado areas. Moreover, this coastal herpetofauna presents evidence of having ecotonal characteristics. Environmental impacts observed in this

area due to the installation of the Port and Industrial Complex underscore the need to implement conservation measures to ensure biodiversity protection. Even if we have not listed threatened species in this municipality, we extended the distribution of two species of anurans and found at least two taxa not yet defined. New studies are required to improve the characterisation of the biodiversity in the region and thus be able to develop a management plan and take appropriate conservation measures.
