This book was released on 2012 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: The alligator snapping turtle (Macrochelys temminckii) is a large freshwater species that has experienced population declines throughout much of its range. In an effort to reestablish an extirpated population in southern Oklahoma, adult M. temminckii were released at Tishomingo National Wildlife Refuge in 2007. I investigated several aspects of M. temminckii reproductive biology within this reintroduced population, including nest-site selection, reproductive and nest predation rates, and patterns of temperature-dependent sex determination (TSD) in natural nests. Water depth two meters from the shoreline and percentage ground cover were important factors in nest-site selection. The nest predation rate was 76% when efforts were made to protect nests and the average clutch size in intact nests was 22.4 eggs. The overall sex ratio in 2010 recruits was strongly female-biased (91.8% female) and a strongly skewed population sex ratio may become a serious threat to this reintroduced population if this trend continues. I also developed a technique to reliably estimate clutch size from predated M. temminckii shell fragments which will improve estimates of mean clutch size (and therefore annual fecundity) for the population. The persistence of several adult M. temminckii and evidence of successful reproduction and recruitment are positive signs, but post-release monitoring will need to continue for several more years in order for this reintroduction to be considered a success.

This book was released on 1997 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The alligator snapping turtle (Macroclemys temminckii) is an uncommon turtle of the Southeast that is a former candidate species for listing as threatened or endangered by the U.S. Fish and Wildlife Service. The species is found in the south-central and southeastern United States throughout the Mississippi River Valley and Gulf Coast States. Alligator snapping turtles utilize a variety of aquatic habitats having permanent water and abundant aquatic vegetation, including rivers, streams, canals, lakes, oxbows, and sloughs. Nests usually are located near water on high and well-drained sites such as natural or artificial berms bordering aquatic environments. The alligator snapping turtle has 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 alligator snapping turtle includes status, life history and ecology, habitat requirements, impacts and cause of decline, management and protection, and inventory and monitoring.

Book Synopsis TURTLE CONSERVATION by : KLEMENS MICHAEL W
Download or read book TURTLE CONSERVATION written by KLEMENS MICHAEL W and published by Smithsonian Books (DC). This book was released on 2000-09-17 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Turtle Conservation provides a comprehensive analysis of threats to turtles and tortoises worldwide. Considering the most significant problems facing the group, Michael Klemens and eighteen international experts on turtle biology and conservation chart successes and failures of past conservation programs, discuss the use of genetics and demography in turtle conservation, and propose more effective strategies that take into account chelonian biology as well as the economic and social situations affecting turtle conservation efforts. They review the outlook for marine, freshwater, semi-aquatic, and terrestrial species; show how turtles make poor candidates for most wild-harvest programs; and propose that turtle and tortoise conservation efforts be integrated into more broadly focused, locally supported land-use projects." "For land and wildlife managers as well as herpetologists and conservation biologists, this book provides a wide-ranging survey of efforts to conserve one of the world's most ancient and endangered groups."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Available in PDF, EPUB and Kindle. Book excerpt: Winner, 2011 Book Award, The Wildlife Society2009 Outstanding Academic Title, Choice Ernst and Lovich’s thoroughly revised edition of this classic reference provides the most updated information ever assembled on the natural histories of North American turtles. From diminutive mud turtles to giant alligator snappers, two of North America’s most prominent experts describe the turtles that live in the fresh, brackish, and marine waters north of Mexico. Incorporating the explosion of new scientific information published on turtles over the past fifteen years—including the identification of four new species—Ernst and Lovich supply comprehensive coverage of all fifty-eight species, with discussions of conservation status and recovery efforts. Each species account contains information on identification, genetics, fossil record, distribution, geographic variation, habitat, behavior, reproduction, biology, growth and longevity, food habits, populations, predators, and conservation status. The book includes range maps for freshwater and terrestrial species, a glossary of scientific names, an extensive bibliography for further research, and an index to scientific and common names. Logically organized and richly illustrated—with more than two hundred color photographs and fifty-two maps—Turtles of the United States and Canada remains the standard for libraries, museums, nature centers, field biologists, and professional and amateur herpetologists alike.

Book Synopsis Ecology of Hatchling Alligator Snapping Turtles (Macrochelys Temminckii) by : Sarah Spangler
Download or read book Ecology of Hatchling Alligator Snapping Turtles (Macrochelys Temminckii) written by Sarah Spangler and published by . This book was released on 2017 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Little is known about the first year of life for many of the world’s freshwater turtles. This is due in part to their cryptic nature and the difficulty of locating hatchlings in the wild. The lack of information about this demographically important age group has led researchers to draw conclusions from indirect inferences about survival rates and ecological roles of hatchlings that may or may not be accurate. To begin filling in some of these gaps, I focused on the first year in an alligator snapping turtle’s life. I studied: (1) circadian and circannual patterns of activity, (2) growth rates and how they are related to activity rates, (3) habitat preferences, (4) fall movement patterns, and (5) predation patterns. My study site was within the species’ natural range in southeastern Oklahoma. Unlike adults, hatchlings followed a predominantly diurnal activity pattern for much of the year, with peak activity occurring during the mid-hours of the day. The diurnal habit of hatchlings may be a strategy to temporally partition themselves from nocturnal predators. There were no significant relationships between growth rates and activity rates during any period, potentially due to small sample size. Hatchlings were located in areas of increased cover and shallower water depths, when compared to random locations. Their movement patterns were characterized by an initial movement away from the site of release to a location with suitable habitat characteristics, and they tended to stay at these locations for extended periods. I documented depredation by fish, but not by terrestrial predators such as raccoons.

Book Synopsis Population Status, Distribution, and Home Range of the Alligator Snapping Turtle (Macrochelys Temminckii) in the Suwannee River, Florida by : Travis M. Thomas
Download or read book Population Status, Distribution, and Home Range of the Alligator Snapping Turtle (Macrochelys Temminckii) in the Suwannee River, Florida written by Travis M. Thomas and published by . This book was released on 2013 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The alligator snapping turtle (Macrochelys temminckii) has experienced population declines throughout much of its range because of extensive harvest. Little is known about the genetically and morphologically distinct population of Macrochelys in the Suwannee River. In Georgia, efforts failed to capture Macrochelys in the Suwannee River, creating concern about this species status. To determine the status of Macrochelys in the Suwannee River, a mark-recapture and telemetry study was conducted between 2011 and 2013. In total, 132 individual Macrochelys were captured (21.2% juveniles, 17.4% females, and 61.4% males). Sex ratio was male-skewed (3.5:1) and 41% of males weighed \U+2265\45kg. Relative abundance and density estimates revealed an uneven distribution of turtles throughout the river, with more productive river sections maintaining higher population densities and larger turtles. Mean linear home ranges were 1,896 m ± 252 m for males and 1,615 m ± 301 m for females. Telemetry data revealed habitat use patterns not previously reported for Macrochelys, with individuals making overland movements between the floodplain and river channel. Side-scan sonar maps paired with turtle locations indicated coarse woody debris, undercut banks and large rocks are important habitat during low water levels. Bush hook surveys and radiographs revealed a positive correlation between bush hook abundance and number of ingested hooks. Macrochelys in the Suwannee are more numerous than previously thought; however, several threats exist including fish hook ingestion, boat propeller damage, and the removal of woody debris.
