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.

This book was released on 2010 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Author's abstract: The alligator snapping turtle (Macrochelys temminckii) is a highly aquatic turtle only found in Gulf of Mexico drainages. The biology of this species remains relatively unknown, despite years of harvest and use as a zoological attraction. The purposes of this study were to (1) determine gender size classes and assess sexual size dimorphism, (2) delineate the reproductive cycle of M. temminckii, particularly their sex steroid seasonality, and (3) evaluate possible genetic divergence between M. temminckii found in southwest Georgia and northern Florida. Alligator snapping turtles exhibit pronounced sexual size dimorphism as adults. However, determining sex in smaller individuals is difficult. The purpose of this study was to assess gender size classes and sexual dimorphism in Macrochelys temminckii. Alligator snapping turtles in southwest Georgia were trapped from March 2008 to April 2010. Captured turtles were bled, sexed based on size and ultrasound, and measured for multiple characteristics. For all measurements, adult males were larger than females. The relationships between carapace length, plastron-to-vent length, and testosterone levels were used to determine gender of smaller individuals. To ensure accurate sexual assignment when studying M. temminckii, data from multiple methods (morphological measurements, ultrasonography, testosterone levels, and, laparoscopy) should be used. To delineate the reproductive cycle of M. temminckii, blood samples were taken from captured individuals, and plasma testosterone and estradiol were measured using enzyme immunoassay. Males exhibited seasonal changes in testosterone levels, with maximum levels occurring in October. Mating behavior was elucidated from the appearance of wounds on males that only occurred in April. Females displayed seasonality in testosterone and estradiol levels, with relative peaks occurring in March and April (mating and ovulation) and September and October (follicular development). Genetic structure between M. temminckii populations separated by a dam and under different hunting pressures was assessed using microsatellite loci. Average number of alleles per locus and number of unique alleles was higher for the Florida population. Genetic structure was detected between the populations (FST = 0.043, p = 0.001). The rapid development of structuring between Florida and Georgia M. temminckii warrants further investigation into the effects of fragmentation and overexploitation on this species.

Book excerpt: The objective of this study was to gather data concerning home range, movements, and habitat use of hatchling Alligator Snapping Turtles ... in order to better manage for this species. Nineteen hatchlings were tracked at Black Bayou Lake National Wildlife Refuge during 2006. Ten animals were successfully tracked during the spring and nine during the fall. Hatchlings that were incubated in the laboratory or naturally on the railroad causeway were heavier and had longer carapace lengths than those naturally incubated along the forest-old field edge of the peninsula (p

Book excerpt: This volume presents 5-year results of silvicultural treatments associated with ecosystem management research in the Ouachita Mountains of Arkansas. Results from stand-level treatments include regeneration dynamics of pine and hardwood species, effects of treatment on birds and small mammals, mast production, visual quality, oak decline, and organic matter. Pretreatment landscape findings include measurements of woody vegetation; birds, mammals, and herpetofauna; fish communities and trophic structure; hydrology; and evaluation of susceptibility to gypsy moth outbreaks.
