Book excerpt: The Blanding's Turtle (Emydoidea blandingii), a species at risk, is expected to become extirpated in urban environments without anthropogenic mitigation. Rouge National Urban Park, along with the Toronto Zoo, is working to create wetland habitat, and is supplementing the existing population with head-starts; turtles raised for two years at the Zoo then released into the wild. The selection and availability of appropriate overwintering sites can minimize turtle mortality. This research examined environmental conditions influencing site selection by head-starts in an artificial wetland complex, 2014-2017. Temperature was determined to significantly influence site use by the turtles. Head-starts preferred cold water (2.16 oC Âą 0.37), close to the shore (

This book was released on 1996 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reports a study conducted to: document the movement patterns of young Blandings turtles (Emydoidea blandingii); and identify areas used by young turtles as rearing grounds and hibernation sites. The study area was located in a park in south-western Nova Scotia. The turtles were hand-reared to an age when they could be fitted with radio transmitters and were then released at four sites, three located on small brooks and the fourth at a small pond. All release sites had boggy floodplain areas dominated by shrubs, grasses, and sphagnum moss. Tagged turtles were tracked daily for the first few days after release to determine whether they would move significantly after release. When determined they would not move significantly, they were positioned by telemetry every 3-7 days and recaptured every 3-14 days. Recaptured turtles were measured and examined to determine their condition. Results are presented and discussed related to turtle survival, movement, predation, behaviour, and habitat use.

This book was released on 2004 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: These studies address the ability of hatchling Blanding's turtles (Emydoidea blandingii Holbrook, 1838) to overwinter in terrestrial and aquatic environments. Currently, it is not known where these hatchlings overwinter or how they survive different environmental stresses in each habitat. In addition, this is the first on antioxidant responses to freezing and anoxia in hatchling turtles, and survival times during freezing and anoxia among species of turtles. First, cold-hardiness and dehydration resistance were studied to determine if hatchlings could overwinter in a terrestrial environment. Hatchlings were susceptible to dehydration and could not rely on supercooling because of a lack of resistance to inoculation. However, hatchlings had a well developed ability to survive freezing at -3.5°C for 72 h. If hatchlings overwinter in terrestrial environments, they probably overwinter in moist areas that limit dehydration and promote freezing at a high sub-zero temperature. The second study examined whether hatchling Blanding's turtles could overwinter in aquatic habitats. The average survival time was 13 d for hatchlings submerged in anoxic water. Approximately one third of the hatchlings died during 75 d of normoxic submergence, but the cause of mortality was unclear. Mortality during hypoxic submergence was likely caused by metabolic acidosis, which resulted from accumulated lactate. Unlike the case with adult turtles, our hatchlings did not increase plasma calcium and magnesium, nor did they sequester lactate within the shell. Our results suggest that hatchling E. blandingii are not particularly well suited to hibernation in hypoxic aquatic habitats. The third study examined relationships between anoxia tolerance and freeze tolerance among several species of hatchling turtles. Freeze tolerance capacity was not necessarily associated with anoxia tolerance. Although lactate concentrations increased during freezing, they were much lower than the concentrations reached during anoxia. Also, liver catalase activity increased in most species following anoxia and freezing exposure, which suggests that constitutive activities of antioxidants are probably insufficient to metabolize increased reactive oxygen species formation during reoxygenation. In conclusion, although a functional anoxia develops during freezing, the accumulation of lactate does not limit survival.

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: With an estimated population of 350 adults, the population of Blanding's turtles in Nova Scotia is listed as Endangered both federally and provincially. Headstarting is used in Nova Scotia as part of the recovery program and is designed to improve the survivorship of turtles at an early life history stage. In 2009 and 2010, the largest Blanding's turtle headstarting effort to date in Nova Scotia was undertaken with eggs collected from Kejimkujik National Park and National Historic Site (KNP). These eggs were incubated and hatched at Oaklawn Zoo, Aylesford, Nova Scotia, and the hatchlings were subsequently raised in captivity for two years. A total of 154 headstarted turtles were re-introduced into KNP during the summers of 2011 and 2012. A total of 29 headstarted turtles released at Atkins Brook were tracked using radio telemetry to study growth and movement. For comparative purposes, 7 wild incubated turtles were also collected and tagged for radio tracking. Turtles were tracked weekly from April to November 2012 to collect movement data and were measured the first week of every month. For the purpose of analysis, turtles were divided into 4 groups: 2009-headstarts, 2010-headstarts, wild (3yrs), and wild (5-7). A pairwise comparison found a difference in movement rates between groups. Wild (5-7) turtles were found to have higher movement rates than all other groups (P

Available in PDF, EPUB and Kindle. Book excerpt: Once a familiar backyard visitor in many parts of the United States and Mexico, the box turtle is losing the battle against extinction. In North American Box Turtles, C. Kenneth Dodd, Jr., has written the first book-length natural history of the twelve species and subspecies of this endangered animal. This volume includes comprehensive information on the species’ evolution, behavior, courtship and reproduction, habitat use, diet, population structure, systematics, and disease. Special features include color photos of all species, subspecies, and their habitats; a simple identification guide to both living and fossil species; and a summary of information on fossil Terrapene and Native uses of box turtles. End-of-chapter sections highlight future research directions, including the need for long-term monitoring and observation of box turtles within their natural habitat and conservation applications. A glossary and a bibliography of literature on box turtles accompany the text. All royalties from the sales of this volume will go to the Chelonian Research Foundation, a nonprofit foundation for the conservation of turtles.

Download or read book Snakes written by Stephen J. Mullin and published by Cornell University Press. This book was released on 2011-08-15 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: Destruction of habitat due to urban sprawl, pollution, and deforestation has caused population declines or even extinction of many of the world's approximately 2,600 snake species. Furthermore, misconceptions about snakes have made them among the most persecuted of all animals, despite the fact that less than a quarter of all species are venomous and most species are beneficial because they control rodent pests. It has become increasingly urgent, therefore, to develop viable conservation strategies for snakes and to investigate their importance as monitors of ecosystem health and indicators of habitat sustainability. In the first book on snakes written with a focus on conservation, editors Stephen J. Mullin and Richard A. Seigel bring together leading herpetologists to review and synthesize the ecology, conservation, and management of snakes worldwide. These experts report on advances in current research and summarize the primary literature, presenting the most important concepts and techniques in snake ecology and conservation. The common thread of conservation unites the twelve chapters, each of which addresses a major subdiscipline within snake ecology. Applied topics such as methods and modeling and strategies such as captive rearing and translocation are also covered. Each chapter provides an essential framework and indicates specific directions for future research, making this a critical reference for anyone interested in vertebrate conservation generally or for anyone implementing conservation and management policies concerning snake populations.
