Parasite Burden and Potential Virus Exposure in the Gopher Tortoise <em>(Gopherus polyphemus)</em>
<p>Long-lived reptiles such as the gopher tortoise (<em>Gopherus polyphemus</em>) may serve as hosts for arboviruses, especially Eastern Equine Encephalitis Virus (EEEV), in the southeastern United States, and such a role may be related to endo- and ectoparasite loads in the tortoise. To assess …

Home Range, Reproduction, and Habitat Characteristics of the Female Gopher Tortoise (Gopherus Polyphemus) in Southeast Georgia
The relationship among female gopher tortoise home range, size, reproduction, habitat characteristics and season were studied for a two-year period (May 2002-May 2004) on Fort Stewart Army Reserve (FSAR) in southeast Georgia. Tortoises were studied in four sectors or regions on Ft. Stewart that …

Gopher tortoise nest-site selection at burrows and the influence of nest environment on hatching success
… sites (canopy, understory, and soil) influences gopher tortoise nest-site selection at burrows and 2) how that nest environment both directly (nest microclimate: temperature and moisture) and indirectly (nest characteristics: nest depth, distance from burrow, canopy and understory cover, percent …

The Role of Gopher Tortoise Burrows (Gopherus polyphemus) in Shaping Herpetofaunal Diversity in the Sandhills of Southeast Georgia
<p> Author's abstract: Gopher Tortoises (Gopherus polyphemus) are known to have large numbers of invertebrate and vertebrate species associated with their burrows. I compared herpetofaunal species diversity and richness at Gopher Tortoise burrows and random points not near burrows on a sandhill in …

Terrestrial Movements and Habitat Use of Gopher Frogs (Rana capito) at Fort Benning, Georgia
<p>Gopher frogs (Rana capito) were radio-tracked between the 2000 and 2001 breeding seasons to study their terrestrial movements and habitat use in a longleaf pine- sandhill area on the Fort Benning Military Reservation, Georgia. The telemetry research was conducted in response to the need for …

Use of environmental variables to infer gene flow and population structure in the gopher tortoise (Gopherus polyphemus) and predict the seroprevalence of an emerging infectious disease
… and gene flow in a federally threatened reptile, Gopherus polyphemus. I also utilize approaches from the field of spatial epidemiology to examine the extent to which environmental variables can be used to predict the seroprevalence of an associated pathogen Mycoplasma agassizzi in gopher tortoise …

Habitat use and activity patterns of Gopher Tortoises (Gopherus polyphemus) inhabiting military test ranges and forested sandhills at Eglin Air Force Base, Florida
The Gopher Tortoise is an important component of a number of upland ecological communities throughout the southeastern U.S., but populations have experienced significant declines over the past century, largely in conjunction with the loss of longleaf pine (Pinus palustris) forests. Military …

Influence of Diet on Growth and Health of Captive Hatchling Gopher Tortoises (Gopherus polyphemus)
<p>Accelerated growth in tortoises has traditionally been associated with potential health risks, however empirical evidence in the literature is lacking. In captivity, growth rates of tortoises are generally expected to exceed those of natural populations and the main cause is probably due to …

Maternal Effects and Offspring Behavior: Potential Contributors to the Lack of Recruitment in Mississippi Gopher Tortoises (<i>Gopherus polyphemus</i>)
<p>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 …

Patterns in the Presence of Respiratory Tract Mycoplasmas in Four Species of North American Tortoises
… tract disease (URTD) in some species of tortoises. Here, we sought to determine the presence and frequency of these bacteria among four North American tortoise species: Gopherus polyphemus (gopher tortoise), G. berlandieri (Texas tortoise), G. morafkai (Sonoran desert tortoise), and G. …
