A Fossil and Zooarchaeological History of the Gopher Tortoise (gopherus Polyphemus) in the Southeastern United States
Specimens of fossil gopher tortoises (Gopherus) were collected from five late Pliocene, two early Pleistocene, five middle Pleistocene, and 52 late Pleistocene sites in 18 counties in Florida, one county in Georgia, three in South Carolina, and one in Mississippi. Occurrences of fossil Gopherus polyphemus in Lowndes County, Mississippi, and Charleston, Colleton, and Horry counties, South Caroli...
متن کاملMultiple paternity and breeding system in the gopher tortoise, Gopherus polyphemus.
Little is known about the reproductive behaviors and the actual outcomes of mating attempts in the gopher tortoise (Gopherus polyphemus). We examined the mating system and reproductive behaviors of a population of gopher tortoises in central Florida. Using microsatellite markers, we assigned fathers to the offspring of seven clutches and determined that multiple fathers were present in two of t...
متن کاملSalmonella from gopher tortoises (Gopherus polyphemus) in south Georgia.
From 2002 to 2006, gopher tortoises (Gopherus polyphemus) were collected at Moody Air Force Base, Lowndes/Lanier counties, Georgia, USA, and opportunistically surveyed for the presence of Salmonella species. Four of 155 (2.6%) cloacal swabs collected from 80 tortoises were positive for the presence of Salmonella enterica, and the following serovars were identified: Give, Hartford, Javiana, and ...
متن کاملTranslocation as a conservation tool: site fidelity and movement of repatriated gopher tortoises ( Gopherus polyphemus )
Efforts to evaluate the efficacy of translocation as a conservation tool have mostly been inadequate, particularly for reptiles and amphibians, leading many biologists to discount translocation as a viable management option. Nevertheless, with two-thirds of the world’s tortoise and freshwater turtle species at risk, translocation may be one of the few remaining options for re-establishing extir...
متن کاملThe effects of constant and fluctuating incubation temperatures on sex determination, growth, and performance in the tortoise Gopherus polyphemus
Temperature-dependent sex determination is one of the best documented yet evolutionarily enigmatic sexdetermining systems. The classical theoretical framework suggests that temperature-dependent sex determination will be adaptive when males and females benefit differentially from development at certain temperatures. Empirical evidence has not provided convincing support for this “differential-f...
