2000 Grant Program

TItis year the board of directors selected four of nine total requests for funding through the annual Grant Program, which has been in operation since the last Midwestern Herpetological Symposium that Minnesota hosted in 1997. The total amount given was $3,431. The following were funded by the Society for this year:

Andrew M. Simons, The Bell Museum, U of M - requested a storage tank for preserved turtle specimens. This tank will be used in the herpetology collection and will replace deteriorating five-gallon buckets. TItis donation should help by contributing to the viability and usefuJoess of the collection that is currently undergoing a major update and renovation. The collection currently has a limited budget for their operations from the University.

Robert Hay, WI DNR - requested for public education programs. Twenty workshops were performed in the southwestern area of Wisconsin in 1998. These were designed to educate landowners of the conservation needs and importance of snakes, identification of the serpents and prairie management guidelines. The funding will bring the workshops into southeastern MN this year in addition to ones to be performed in Wisconsin.

Tony P. Murphy, MN Frog and Toad - funding for survey program. The funding provided will go toward the production of education materials for the Frog and Toad Survey materials and for distribution and solicitation of volunteer participants. The MNDNR is also contributing to this program and is now active in the administration.

Dan Keyler, Leslie Tannahill, Kimberly Fuller, independent study -MN Timber Rattlesnake Transient Movements. This study will assess the movement, gene flow and population viability along with producing management strategies for Timber Rattlesnakes in southeastern MN.

TItis year the board entertained many worthwhile projects submitted through the Grant committee. The purpose of this committee is to solicit and to insure submissions to the society for Board consideration. It is not intended to limit submissions nor to set a yearly timetable. If any person or organization has a need for funding at any point in time, they are encouraged to submit their request to the society. Moreover, if anyone knows of others 50 in need~ please inform them of our program or refer them to any Board member or to the Grant Committee chair. The SOciety has given many grants prior to the current program and will continue to do so as long as funding is available and the membership considers it a priority. -REBIasus

Note: New Library Books

Two books were received late last year and are: from the Herpetological Library Series of Advanced Vivarium Systems Essential care of Chameleons, (1999) by Philippe de Vosjoli and What's Wrong with My Iguana? (1998) by John Rossi. TItis month, March, the book received was the Field Guide to Amphibians and Reptiles of Illinois (1999) by Christopher A. Phillips, Ronald A. Brandon and Edward O. Moll. An article donated by our March speaker, Bruce Means, will be available; it is found in the BBC Wildlife, February 2000 issue.

One of the missing books has been replaced (at cost) Minnesota's Endangered Flora and Fauna (1988) Barbara Coffin, Lee Pfannmuller ed. However, all the missing books are still outstanding.

Next months arrivals will include; Timber Rattlesnake (Crotalus horridus) DNA: Haplotype and Lineage in the Upper Mississippi River Valley (2000) Daniel E. Keyler funded from a 1998/99 MHS grant Another publication by Bruce Means was purchased this is Diamonds in the Rough (1994) and is an excerpt from a book that he is currently working on. -REBlasus

The Animal Humane Societies

WALK FOR ANIMALS

On Saturday, May 6th the area Humane Societies are having Walks for fund raising. These are their largest fund raising events of the year. There are walks in Hennepin County (Golden Valley), Ramsey County (Woodbury and Como Park). These are great opportunities to get out with other pet owners and show off your Herps as pet too. I have been doing this for 5 years and enjoy bringing my alligators to this walk.

People don't believe that there are these types of animals here in Minnesota. The last couple of years there have been more and more unusual (reptiles) animals at these events. Having very short legs or no legs, most reptiles will need to ride in wagons or be carried. Wagons work best because you can still walk and others can still look at your pets. In the past I have had my gators photos in the paper and on the news because they are some of the most unusual animals there.

There are over 7000 people at the Golden Valley walk, with over 4000 animals- horses, goats, rabbits, mice, rats, ferrets, iguanas, birds, and many dogs and cats. I know that some herp owners also have dogs or cats and may have even gotten them at the Humane Sodety, this is an opportunity to show others that we care about all unwanted and abandoned animals.

A Review of Albinism By Tony Gamble

Originally published in "Olit Glat: Newsletter of the Global Gecko Association, Number 3"

When most people get face to face with an albino reptile the first question out of their mouth is usually, "Why isn't it white?"

When placed side by side, an albino mouse certainly does look different than an albino com snake (a situation that unfortunate albino mice are put in very frequently). The mouse has white fur, pink skin and the characteristic pink eyes. The corn snake, on the other hand, does possess the pink eyes but the skin has a bright orange and red pattern. How can they both be called albinos?

The term albino is typically used to define an animal 1/ deficient in pigmentation." Since mammals have only one kind of chromatophore (pigment cell), the melanin producing melanophore, you end up with a white and pink animal (the pink color comes from blood vessels under the skin).

Reptiles, on the other hand, have four types of chromatophores (pigment celIs): melanophores-synthesize melanin and are responsible for black and brown colors as well as some yellow and red colors; xanthophores- store carotenoids which are yellOWiSh to reddish pigments that are taken in tluough food; erythrophores­synthesize the pteridine pigments that make most red and orange colors; and iridophores-cells that produce color by reflecting and refracting light off of stacks of purine platelets, they are responsible for many of the green colors in reptiles and for the iridescence in many snake species. A fifth kind of chromatophore, the mosaic chromatophore, is also known. These types of celIs are like hybrids of the above mentioned chromatophores and can possess, potentially, any combination of these pigments. Currently, these celIs are fairly rare (they are found for example, in the

II A Whiter Shade of Pale"

dorsal stripe of Thamnophis proximus) but as more research is performed on reptilian skin, they will probably shown to be more common.

Chromatophores are found primarily in the dermis, the underlying base of the skin that aIso contains blood vessels, temperature and pain receptors, and connective tissue. The epidennis, the outer layer of skin, contains only epidermal melanophores. Dermal melanophores (melanin producing celis in the dermis), by the way, are the celIs that are responsible for most of the rapid color change that occurs in many lizard species.

An albino reptile could have a problem producing pigment in any one of these four types of cells yet still have the other three to produce some color. A good example is the albino com snake again. They do not produce melanin (so no blacks or browns) but still have healthy xanthophores and erythrophores to produce the yellow, orange, and red colors that make albino com snakes so distinct.

Some common tenns used to explain these pigmentation defects are:

Amelanistic-Iacking melanin Anerythristic-Iacking red color Axanthic-Iacking yellow color Hypomelanistic-reduced melanin I..eucistic-white Melanistic-excess black color Xanthic-excess yellow color Keep in mind that often, no One

knows exactly what the underlying cause of a color defect may be so these terms are used somewhat loosely.

Figure 1

How is Melanin Produced?

Another source of variety in color mutations is that prodUCing pigments is a process that occurs in steps and that a defect can occur at anyone of those steps. The amelanistic tyrosinase+ /tyrosinase- mutations are a good example of this. Tyrosinase is an enzyme that is essential to the production of melanin (see figure 1) and tyrosinase- albinos cannot produce melanin as a result. Tyrosinase+ albinos can produce tyrosinase but, for whatever reason, still cannot produce melanin. There is, in most instances, a difference in color between the two varieties.

Humans, possessing only melanophores, have had six· distinct types of albinism identified and each one is the result of a different, defective gene. Each type also looks a little different The increased complexity of reptilian coloration would then, naturally lead to an increased complexity in the problems that afflict their integument As a result, each case of aberrant coloration in a reptile needs to be examined independently and a level of understanding needs to be reached regarding the terms that describe these differences. Our understanding of these mutations will hopefully continue to grow and so will our appreciation of the animals.

THE ROOT RIVER NATURALIST

"SNOW SNAKES" Despite the positively balmy last

days of March, lingering patches of snow still adorn the landscape throughout most of southeastern Minnesota. Indeed, wherever one goes in the blufflands this persistent reminder of the season just past yet blankets north facing hillsides and fills the valleys and gullies below. Our trees too, perhaps awaiting the arrival of April's fabled showers, seem reluctant to awaken and still stand silent, forlorn and naked in their drab winter clothes.

This fleeting, all too brief season when winter melts imperceptibly away into spring, howevert is perhaps the best time to take a walk in the woods. Certainly the very bareness of the trees, the absence of low growing foliage and the disappearance of autumn's carpet of fallen leaves allows us an unobstructed view of our woodlands unavailable at any other time of the year. Ponds, rocks and other topographic features, so efficiently hidden by the grass, shrubs and leafy trees of summer, now all plainly visible and so readily explored. Better still, no stinging, noxious plants and no pesky biting insects yet expect to extract their painful payment for all this outdoor fun.

At the same time, the milder weather and gradually melting snow has stimulated our long slumbering wildlife. Early woodland wildflowers sprout and expose their colorful, fragrant blossoms to the soon to be stolen sun. Swanns of hatching midges and other aquatic insects feed ravenously hungry trout, who in tum may soon feel the sting of the hook and end up in some angler's frying pan. Raccoons and opossums, now fully aroused from their long winter naps, busily forage for food, while squirrels of all shapes and sizes angrily scold and chase after neighbors as they seek to re-established the boundaries of their territories. Birds, including many species that haven't been seen for months, arrive in ever increasing numbers as well.

Of all these early spring anirnals, the Common Garter Snake is surely among the more interesting and is the one species I am always most happy to see. Occurring in virtually every county of the state, Garter Snakes are certainly the most common and readily recognized of all of Minnesota's 17 or 50 resident snake species.

Widespread throughout the rest of the continental United States as well, these inoffensive serpents are often and perhaps more appropriately called 'Garden Snakes' due to the frequency with which the species are found in both rural and urban gardens and yards. While their presence in such situations may be somewhat disconcerting, Garter Snakes are not venomous and are therefore completely harmless to humans. Like most wild animals, however, these snakes will bite in self-defense if molested but are incapable of inflicting more than superficial scratches that cause relatively little if any pain.

Unlike most terrestrial reptiles, Common Garter Snakes are quite tolerant of cooler weather conditions and the species is nonnally active well before winter's snow has fully melted. In fact, here in southeastern Minnesota I have personally observed these supposedly 'cold-blooded' animals rapidly crossing snow-covered patches of ground on numerous occasions. Other researchers have reported the utilization of snow as a source of fresh drinking water by these snakes as well.

This almost uncanny ability to not only survive, but actually thrive in adverse climates has allowed the Common Garter Snake to colonize areas inhospitable to most cold­blooded vertebrates. Not surprisingly, the species is found much farther north than any other reptile in the New World with colonies of literally thousands of Garter Snakes known to occur at least as far north as central Manitoba. There, in one of the most spectacular sights in the animal kingdom, huge aggregations composed entirely of this species gather annually for mating each spring. In the frenzied orgy of activity that follows, dozens of male Garter

6

By John P. Levell Snakes may all be attempting to mate with a single, much larger female. Males that successfully breed deposit a 'post-copulatory' plug in the female's cloaca or vent:, which minimizes the chances of fertilization by other competing males. In an even more bizarre evolutionary twist,. some 'feminized' males secrete a glandular substance that mimics the scent of female Garter Snake pheromones, which theoretically confuses potential rivals and increases the chances of breeding success.

Again unlike most reptiles which lay eggs, Garter Snakes give birth to fully formed living young typically in late summer or early fall. This is yet another adaptation to colder climates, as it allows females to select the environmental conditions most advantageous to the embryonic development of her offspring. Litter size averages betvveen 15 to 20, although some exceptionally large females have been known to give birth to as many as 100 young.

Although often found near water, Garter Snakes are highiy adaptable and will inbabit a tremendous assortment of habitats including marshes, praInes, woodlands, pastures, vacant city lots, cemeteries and even golf courses. By no means finicky feeders, Common Garter Snakes consume virtually any animal that can be captured and subdued. Worms, insects, fish, frogs, salamanders, birds and small mammals are all included in the extensive list of prey species eaten by these snakes.

While certainly widespread and numerous, the behavior, adaptability and success of the Cornman Garter Snake makes it far from commonplace indeed!

New Book On Deformed Frogs due out

in March

From a review by Tom Meennan of the Star Tribune, March 8, 2000, page A16.

nyou wouldn't think that a book about frogs would be all the interesting. Herpetology is after all, "the filmy, dank science of slithery things living in dark, wet places," according to Minnesota writer, William Souder. But, "A Plague of Frogs" - Souder's first book- is not about ordinary frogs. "The Horrifying Tme Story," as the subtitle says, begins with an incident that cast Minnesota as a principal player in a continuing national and international scientific mystery.u

More Notices

The article goes on to cite when schoolchildren near Henderson, Minn. noticed young frogs with missing and shortened hind legs in 1995. Souder chronicles the next four years of research and speculation. Covering the story as a writer for the Washingtem Post, he became an active participant, wading through wetlands, peering through microscopes and seeing the politics involved in scientific research and hypotheses.

"It's a complicated mystery with more questions than answers. After four years of research, writes Souder, no one can say with certainty why frogs in Minnesota and elsewhere have occurred or what that could mean.

William Souder's book "A Plague of Frogs: The Horrifyillg True Story" (Hyperion, 299 pages, $23.95) will be published Mard.15.
