Book Biology and Conservation of North American Tortoises

Download or read book Biology and Conservation of North American Tortoises written by David C. Rostal and published by JHU Press. This book was released on 2014-08-01 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most comprehensive book ever published on North America's native tortoises. Tortoises, those unmistakable turtles, evolved from a lineage that split off from the familiar pond turtles roughly 100 million years ago. Over time, these plant-eating land turtles spread around the world, growing to an enormous size (depending on the species) and living so long that they have become the stuff of legends. By most accounts, they are indeed the longest-lived of the turtles, with good records suggesting individuals may live as long as 180 years (anecdotal records suggest that some reach ages of 200 years or more). Providing the first comprehensive treatment of North America’s tortoises, Biology and Conservation of North American Tortoises brings together leading experts to give an overview of tortoise morphology, taxonomy, systematics, paleontology, physiology, ecology, behavior, reproduction, diet, growth, health, and conservation. The contributors carefully combine their own expertise and observations with results from studies conducted by hundreds of other researchers. The result is a book that belongs in the library of every herpetologist. Contributors Gustavo Aguirre L. Linda J. Allison Matthew J. Aresco Roy C. Averill-Murray Joan E. Berish Kristin H.

Book The Effects of Gopher Tortoise Gopherus Polyphemus Translocation on Movements Reproductive Activity and Body Condition of Resident and Translocated Individuals in Central Florida

Download or read book The Effects of Gopher Tortoise Gopherus Polyphemus Translocation on Movements Reproductive Activity and Body Condition of Resident and Translocated Individuals in Central Florida written by Susannah Christina Riedl and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Human-caused destruction of xeric habitats in Florida that support gopher tortoises (Gopherus polyphemus Daudin) is occurring at a rapid rate. One conservation strategy that has been used for numerous taxa is translocation. The effects of translocation on the health, reproductive activity, and movements of translocated and resident telemetered individuals was evaluated for a population of gopher tortoises in central-Florida from 2001 to 2004. Only one of the 13 individuals released left the site during the study. The home range estimates of resident individuals were not significantly different before and after the release of the translocated individuals on the site, and all mean home ranges fit within the range of estimates reported in the literature for natural populations of gopher tortoises. Habitat use of several individual resident gopher tortoises was significantly different after the translocation events. The degree that the home ranges of the residents were overlapped by other individuals in the study was not significantly different. The spatial locations of the home ranges of resident and translocated individuals were significantly different. There was evidence of reproduction for both resident and translocated females a year after the release of the translocates. The body condition of the resident individuals was higher at the end of the study relative to the start, although this may be explained by other factors. This study illustrates some of the problems associated with studies designed to assess translocation success, namely the lack adequate baseline data for the population and the challenge of balancing the sample sizes necessary for acceptable statistical power with the mechanics of translocation. The results of this study suggest that translocation is a potentially useful conservation strategy, although there are other potential consequences of translocation that need to be considered prior to its implementation.

Book Species Profile Gopher Tortoise Gopherus Polyphemus on Military Installations in the Southeastern United States

Download or read book Species Profile Gopher Tortoise Gopherus Polyphemus on Military Installations in the Southeastern United States written by and published by . This book was released on 1997 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: The gopher tortoise (Gopherus polyphemus) is the only tortoise that occurs east of the Mississippi River. The U.S. Fish and Wildlife Service has separated the species into two main populations. The western population (southwest Mississippi and southeast Louisiana) is Federally listed as threatened; the eastern population, which occurs in southern Alabama and Georgia, extreme southwestern South Carolina, and most of Florida, is a former candidate for listing as threatened. Gopher tortoises occupy a wide range of open, upland habitats with a well-drained, deep sandy substrate, primarily longleaf pine-xerophytic oak woodlands (sandhills). They have been documented on several military installations in the Southeast. This report is one of a series of 'Species Profiles' being developed for threatened, endangered, and sensitive species inhabiting southeastern United States plant communities. The work is being conducted as part of the Department of Defense (DoD) Strategic Environmental Research and Development Program (SERDP). The report is designed to supplement information provided in plant community management reports for major United States plant communities found on military installations. Information provided on the gopher tortoise includes status, life history and ecology, habitat requirements, impacts and cause of decline, management and protection, and inventory and monitoring.

Book Maternal Effects and Offspring Behavior

Download or read book Maternal Effects and Offspring Behavior written by Aaron Lee Holbrook and published by . This book was released on 2015 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Federally threatened in Mississippi, gopher tortoise (Gopherus polyphemus) populations within the state have strongly variable recruitment and are generally in decline. Hatching success is significantly lower in Mississippi than in any other part of the species' range, and most hatchlings die within the first year. There are few refuges where survival and hatching success is high. Here I compare two populations that differ in recruitment and offspring survival for differences in corticosterone. Corticosterone is a hormone that influences energy availability and is released in elevated levels during stressful events, like living in poor quality habitat. Prolonged corticosterone elevation can impede growth and immune responses and result in early death. To assess adult stress, I utilized leukocyte profiles as they are influenced by prolonged elevation of corticosterone. A viable yolk sampling technique was used to collect yolk samples to determine levels of yolk CORT. Hatchlings were then kept in captivity for two years to observe growth rates and burrowing behavior before being released and monitored via radiotelemetry to monitor dispersal and survival. I found no differences in adult stress or egg yolk CORT between populations. This suggests adults are not excessively stressed. Survival of hatchlings did not differ between sites. Captive-reared hatchlings were larger and may have better survival than similar aged wild hatchlings. Overall, the poor survival of gopher tortoises may be more strongly linked to environmental variables such as soil structure than physiological ones. --Page ii.
