However, captive animals can exhibit unnatural behaviors and experience high preda- tion following release, which can limit reintroduction success and the inferential value of studies that use released animals. Soft-release measures (e.g. penning) can acclimate individuals and limit interactions with predators but can also require considerable resources. We reared hatchling gopher tortoises Gopherus polyphemus in the laboratory for physiology experiments and subse- quently hard-released them as yearlings to assess the efficacy of this low-cost release method and to explore possible captivity effects on tortoise behavior, growth, and survivorship. Hard-released yearlings exhibited limited dispersal; most constructed burrows soon after release, and, like wild juveniles, exhibited a preference for burrowing under deadwood. Video observations at burrows indicated natural behavior, including overnighting in burrows, extensive basking directly in front of burrows, and limited time away from these important refugia. Basking tortoises responded to simulated predator approach by rapidly entering burrows, with flight initiation distances and hid- ing times equivalent or similar to those of wild individuals.

Specifically, turtles and tortoises are generally perceived as providing no nest protection once the eggs are laid. Here, we describe observations of nest guarding by female gopher tortoises (Gopherus poly- phemus). Nest guarding among reptiles is considered uncom- mon (Reynolds et al. 2002).

  • Turtles, Tortoises, and Terrapins by Sandie Lee
    Name: _______________________ Turtles, Tortoises, and Terrapins by Sandie Lee Are You a Turtle, a Tortoise, or a Terrapin? For 215 million years, our shelled friends have lived with a mistaken identity. It’s understandable. We think – if it has a shell, it must be a turtle…right? Not quite. There’s actually around 300 different species of turtles, tortoises and terrapins. So what’s the difference? To Be or Not To Be a Terrapin An easy way to tell a terrapin from a turtle is from its coloring. Terrapins have bright yellow and green patterns on their shells and bodies. These animals live in fresh or brackish (partly salted) water. They are commonly found in ponds and river beds where they will bask in the sun on rocks and logs. Their feet are designed both for swimming, with webbed toes and sharp claws for climbing. This small group includes the Slider and Red-Eared Slider which has jaunty This Red-Eared Slider is a terrapin. red stripes along its face and is also commonly sold in stores. Do you know someone who keeps a terrapin as a pet? Built Tortoise Tough Like a sturdy truck, tortoises are built for the rugged terrain and live strictly on land. They have thick, stumpy legs and claws that help propel them forward and dig deep holes. The Gopher Tortoise is able to dig underground tunnels over 40 feet long and 10 feet deep. No meat is required in a tortoise’s diet, they’re purely vegetarians. But that doesn’t stop the Galapagos Giant Tortoise from weighing This Galapagos Giant Tortoise lives only on land.

Castellano, Director, Turtle Conservation Initiative, The Orianne Society The Orianne Society was established in 2008 for the conservation of the Eastern Indigo Snake (Drymarchon couperi) in the southeastern United States. Since its inception, however, it has expanded its mission to the conservation of threatened reptiles and amphibians worldwide. Most recently, the Society created the Turtle Conservation Initiative (TCI) in response to the extinction crisis that is threatening the survival of more than half of the world’s turtle species. The vision of the TCI is healthy and sustainable populations of turtles in the wild, living alongside human societies that value them. The TCI will include a diversity of programs that promote science-driven conservation action for turtles by focusing on six key action areas: applied science, community-based conservation, human-wildlife conflict, Radiated Tortoise (Astrochelys radiata) of environmental education, professional development, and public Madagascar, a focus of the Orianne Society’s Turtle Conservation Initiative.

TEMPERATURE-DEPENDENT SEX DETERMINATION IN MANOURIA EMYS EMYS, THE ASIAN FOREST TORTOISE by SHERRI EMER Under the Direction of Matthew Grober ABSTRACT Captive husbandry programs in zoos have documented nesting behavior and have successfully hatched Manouria emys emys, but data on sex determining mechanisms and sex ratios are absent. A total of 30 M. e. emys eggs were artificially incubated at five different temperatures in constant humidity. Mean incubator temperatures were 24.99°C, 25.06°C, 27.18°C, 28.00°C, and 30.79°C. Incubation duration ranged from 60 days to 92 days, and hatching success was 50%. Sex determined by histology and laparoscopy resulted in male differentiation at low temperatures (24.99°C, 27.18°C) and female differentiation at high temperatures (30.79°C). Pivotal temperature was estimated to be 29.29°C. The following investigation into temperature-dependent sex determination (TSD), including its presence or absence, pattern, and pivotal temperature, has implications for studies of adaptive significance of reproductive behaviors and of chelonian phylogenetic history.

Slide 1 *Ask kids if anyone has seen a gopher tortoise and where.* NOTE: ‘*…*’ will indicate a suggestion for interaction with the kids in the audience. Slide 2 Gopher tortoises have flat, shovel like front feet for digging long burrows, and stumpy elephant- like back legs. They have a broad head with flat snout. * ”Did the tortoises you’ve seen look like this?” * Slide 3 Baby gopher tortoises are called juveniles. Juveniles are less than 5 inches long and have a soft shell with a yellow/orange color. Their shells will get hard at about 7 years of age. Since adults do not look after the hatchlings, and since their shells are soft for so long, juveniles are quite vulnerable to their environment and other species that live in it. They may use an existing burrow or even dig their own tiny one for shelter. *Pass around ping pong ball for size comparison of tortoise eggs.* Slide 4 Adult gopher tortoises will have a gray/brown color.
