The gharial is characterised by its extremely long, thin jaws, which are regarded as an adaptation to a primarily piscivorous diet. Males reach up to 6 m (20 ft) with. 2017-04-26 Gerry Salmon -Prey Selection in Western Copperheads (Agkistrodon laticinctus) This presentation is an overview of research being conducted on the diet of. The Crocodilia (or Crocodylia) is an order of mostly large, predatory, semiaquatic reptiles, known as crocodilians. They first appeared 83.5 million years ago in the. Broad- snouted caiman videos, photos and facts - Caiman latirostris. Due to a lack of field studies, very little is known about the behaviour and ecology of the broad- snouted caiman, and much of what is known about its reproduction has come from captive individuals in zoos (6). The broad- snouted caiman nests during the rainy season (August to January in Brazil, January in Uruguay, and January to March in Argentina), when decaying vegetation is collected from around a nest site and scraped into a mound (2)(5). The male assists with constructing the mound nest, but the female becomes more aggressive as incubation continues, and only the female tends the nest (5). Around 2. 0 to 5. This layering of the eggs may help to create a slight difference in temperature within the nest and a slightly different sex ratio in the embryos (7), since only females are produced between 2. Celsius, only males are produced at 3. Celsius, and both males and females are produced at 3. Celsius (8). After an incubation period of around 6. For their first year, the hatchlings cluster in the water close to the nest, all the time being closely attended by both the adults as protection from predators (5). The broad- snouted caiman has a varied diet that includes shrimp, fish and birds (7), but in some parts of its range it feeds mainly on snails (6). To maintain its body temperature, it basks for about 3. It is only active on sunny days during the winter. The broad- snouted caiman can apparently survive colder temperatures than other crocodilians in the region, and its dark colour may be an adaptation to this, as darker colours are better at absorbing light which is converted to heat (5).

Gerry Salmon - Prey Selection in Western Copperheads (Agkistrodon laticinctus)This presentation is an overview of research being conducted on the diet of copperheads (Broad- banded and Trans- Pecos populations) based on field observations, and work in museum collections and in captivity. The two formerly recognized subspecies (now recognized as A. Results reveal a varied diet that may follow seasonal trends. Additionally this highly evolved ambush predator exhibits foraging behaviors that allow it to capitalize on seasonally available insect and amphibian prey. This study (conducted in collaboration with Harry Greene) has recorded several novel species included in the diet, and is relevent in captive management of wild specimens (consistent feeding) and for eliciting feeding in neonates and juveniles which may refuse typically available rodent prey. Presented by Gerry Salmon, Member of SSAR, Southwestern Center for Herpetological Research (current VP), South Texas Amphibian and Reptile Society, Austin Herpetological Society, Chicago Herpetological Society and East Texas Herpetological Society. He has been an avid naturalist with a strong interest in Herpetology and geographic distribution of North American reptiles. He has been doing natural history research for more than 3. He is a retired New York State Police Sergeant, a former state park naturalist for New York and South Carolina, and has worked as an endangered species monitor on pipeline and wind farm construction projects. He resides in Boerne, Texas. Dr. Hileman - Demography and Life History of an Imperiled North American Rattlesnake (Sistrurus catenatus)The Eastern Massasauga (Sistrurus catenatus) is a small, cryptic North American rattlesnake with a distribution centered on the Great Lakes. Ongoing population declines due to habitat loss, habitat fragmentation, and harvest led to the species being listed as threatened and endangered in Canada and threatened in the United States under the U. S. Endangered Species Act in 2. Population estimates are essential for identifying population trends, assessing extinction risk, and elucidating the effects of land management practices on population persistence. However, conservation of Eastern Massasauga populations has been hampered by data gaps related to how the species varies in life history and demography across the range. For example, key demographic estimates are lacking for populations near the range center of the species where the largest number of Eastern Massasauga populations may still persist. Consequently, realistic extinction risk models and management guidelines related to the timing of habitat management activities have been difficult to develop. Hileman will discuss research he and fellow collaborators are doing that will inform conservation efforts for this imperiled snake. Eric T. Hileman is a postdoctoral fellow in the biology department at Trent University in Peterborough, Ontario, Canada. He is interested in traditional and spatially explicit capture- recapture models, population ecology, life- history evolution, and conservation biology. Eric is the former Director of Conservation, Education, and Animal Welfare at the Racine Zoo in Racine, Wisconsin. He has taught field- based tropical herpetology courses in Costa Rica for the last decade. Rich Crowley - Passionate Journey With Short- tailed Pythons. Keeping short- tailed pythons since 1.

Crump - What Amphibians and Reptiles Mean to Us: Lore, Mythology, and Conservation Throughout time and worldwide, humans have loved and hated amphibians and reptiles. Marty was born in Madison, Wisconsin. Radio- telemetry, visual encounter surveys, and trapping were used to study the ecology of this species living on a barrier island off the coast of New York. Snakes on the island were found to be lacking color polymorphisms, feed exclusively on Fowler's Toads, and to occur in extremely dense populations. The snakes also nested and denned communally, and used smaller home ranges than those in other populations. John earned an MS in Biology from Hofstra University in NY, where he studied the ecology of Eastern Hog- nosed Snakes on a barrier island. He also has a BS in Wildlife Science from The State University of New York College of Environmental Science and Forestry (which has the longest name of any university in the United States). Throughout his career, John has had the good fortune to work with Eastern Hellbenders, Timber Rattlesnakes, Black Bears, Red Wolves, Gopher Tortoises, Peregrine Falcons, and a suite of other species. His current research at NIU focuses on the distribution of reptiles, amphibians, birds, and mammals in Lake County, IL. Ted Levin - America`s Snake: The Rise and Fall of the Timber Rattlesnake. Of all the rattlesnakes in the Western Hemisphere, the timber rattlesnake has evoked the widest, most controversial constituency. The first venomous snake encountered by European colonists, it was the first New World snake classified by Linnaeus, who gave it the Latinized name Crotalus horridus, which translates to scaly beast with musical rattle. Levin's book captures the snake's natural history and unique behaviors, and looks at the people who love them, loathe them, and have abused them through illegal trade. A former Bronx Zoo zoologist, Levin is the author of Blood Brook: A Naturalists Home Ground, Backtracking: The Way of the Naturalist, and Liquid Land: A Journey through the Everglades, which won the Burroughs Medal in 2. He has written for Sports Illustrated, Audubon, National Wildlife, National Geographic Traveler, and other publications. For many years he has led tours to the rattlesnake- rich landscapes of the Southwest and Southeast. In the summer of 2. Ted organized and led a team of eleven- and twelve- year- old Little League all- stars on a goodwill baseball tour of Havana, Cuba, the first trip in more than fifty years to be sanction by both the United States and the Cuban government's.
