Migratory Ecology of Sea Turtles
… true for migratory species, such as sea turtles, whose long-distance movements form a major component of their life history. In this thesis, I investigated which factors are driving the migratory behavior of the leatherback turtle<em>Dermochelys coriacea. </em>Firstly, I examined whether …

Seed Dispersal by Aquatic Turtles
… dispersal capabilities by several common aquatic turtles in Southwestern Missouri were investigated. Fecal matter was first obtained during a summer seed survey in which stinkpots (Sternotherus odoratus), river cooters (Pseudemys concinna), spiny soft-shell turtles (Apalone spinifera), and common …

Geographical Distribution and Morphometrics of South Dakota Turtles
… information has been published on South Dakota turtles compared to the neighboring Midwest states. This study was conducted to compile literature relevant to the species of turtles that occur in the state; develop proper protocols for field collection, morphological measurement, live animal …

Reintroduction Biology of Head-Started Ornate Box Turtles
… I tested the null hypothesis that reintroduced turtles exhibited equal reintroduction success when, 1) released at a site that is known to support a viable ornate box turtle population, 2) ‘soft-released' in a fenced enclosure at a site where very few ornate box turtles persist, or 3) …

Locomotor kinematics of turtles moving in shallow water environments
… may open insight into new locomotor strategies. Turtles are an interesting study subject to study water-land transitions, as their spines are fused to their carapace, isolating any movement generation to their limbs only. In this thesis, I chose different size red-eared slider (Trachemys scripta …

The Distribution and Ecology of Two Kinosternid Turtles in Iowa
… habitat preferences or behavior of Illinois mud turtles and stinkpot turtles in Iowa, at the extreme edge of the species' ranges. The mud turtle is restricted in Iowa to ephemeral ponds associated with Sparta sand or Chelsea loamy fine sand. The stinkpot is restricted to permanent water with Colo …

Molecular ecology of hawksbill turtles Eretmochelys imbricata in the Seychelles
Molecular genetics are an invaluable tool in whole-organism biology, allowing the indirect investigation of life history traits and evolutionary processes that are otherwise unobservable. In this thesis, I apply molecular genetic techniques to the study of the hawksbill sea turtle Eretmochelys …

Effects of Habitat on Physiology and Infection in Aquatic Turtles
Finally, Salmonella infections in slider turtles were not significantly affected by the host or habitat characteristics measured in this study. No turtles out of 100 were shedding Salmonella. Dissections of 73 turtles, however, revealed that turtles in the region had a moderate prevalence (11%) of …

Ecology and Genetics of Blanding's Turtles in an Urban Landscape
… potential effects of urbanization on Blanding's turtles are not well established. To develop a better understanding of how Blanding's turtles respond to urban development, I initiated an investigation of the ecology and genetics of Blanding's turtles in the intensely developed Greater Chicago …

The Ecology and Evolution of the Freshwater Turtles of Southern Mississippi
<p>Turtles are one of the most threatened group of animals in existence today. The Southeastern United States is one of two global biodiversity hotspots for turtle species, including the state of Mississippi, where over 30 species can be found. However, very few studies have occurred within the …

Nesting Ecology of Hawksbill Sea Turtles (Eretmochelys imbricata) on Utila, Honduras
… to two nesting hawksbills, and found the turtles migrated to different countries. One turtle traveled 403 km to a bay in Mexico, and the other traveled 181 km to a Marine Protected Area off Belize. This study presents the first description of hawksbill migration routes from Honduras, …

Bycatch and foraging ecology of sea turtles in the Eastern Pacific
<p>Sea turtles are long lived marine species that are currently endangered because their life history and population dynamics hinder them from withstanding modern anthropogenic threats. Worldwide, fisheries bycatch in on the major threats to the survival of sea turtles and that is also the case in …

Demography of Alligator Snapping Turtles (Macrochelys Temminckii) Along a Fishing Pressure Gradient
<p>Passive fishing gear is a threat to the alligator snapping turtle (<em>Macrochelys temminckii</em>). The spatio-temporal persistence of this threat and its impacts on <em>M. temminckii</em> populations has not been quantified. I quantified the density of passive fishing gear and the demographic …
