Seasonal Testosterone and Reproductive Cycles in Yellow-Bellied Slider Turtles (Trachemys Scripta Scripta)
<p>The yellow-bellied slider (Trachemys scripta scripta) is one of the most common species of freshwater turtles in the southeastern United States, yet little information pertaining to its reproductive biology and seasonal hormone cycle has been documented. The major purposes of this study were to: …

The Renin-Angiotensin System in The Freshwater Turtle Pseudemys Scripta
… in this species. It was shown that Pseudemys scripta possess renal renin, renin substrate in the plasma, angiotensin converting enzyme activity, and vascular receptors specific for angiotensin. Kinetic analyses were performed on the turtle renal renin (kidney extract) plus turtle renin …

Studies of atrial natriuretic peptide in the freshwater turtle Pseudemys scripta
Attempts to purify further the active component using reversed-phase HPLC techniques and the radio-receptor assay resulted in the isolation and sequencing of two ANP receptor-binding peptides. These peptides were not homologous to ANP but rather were homologous to the muscle protein fragments …

Elucidating the conservation status of Michigan's red-eared slider (trachemys scripta elegans): A phylogeographic approach
<p>The geographic origin of Michigan’s Trachemys scripta elegans has been a contentious subject since its first description in 1934. At that time two explanations were proposed: 1) populations of T. s. elegans are native to Michigan and naturally expanded their range from Ohio and Indiana; or 2) …

Passive Electrical Properties of Horizontal Cells in the Retina of the Turtle, Pseudemys Scripta Elegans
A core conductor analysis was applied to the passive relaxation of the transmembrane potential in response to 20 ms pulses of current in luminosity-type and chromaticity-type horizontal cells. The time course of the relaxation was described by the sum of two exponentially decaying processes. The …

Growth, Diet, and Reproduction of the Red-Eared Slider (Trachemys Scripta) Inhabiting a Reservoir Receiving a Cold Effluent
Red eared sliders, Trachemys scripta, were collected from two habitats at Lake Taneycomo from April 1992 to July 1993. One site was a hypothermic cove near Rockaway Beach, Missouri, and the second site was a normothermic cove in a tributary of Lake Taneycomo known as Bull Creek. The diets of adult …

Nest Emergence and Chemosensory Mediated Predator Avoidance: Two Studies of Behavior in the Red-Eared Slider (Trachemys Scripta Elegans)
Predator avoidance is a key to the survival of any species. The emergence of offspring in a single event (mass emergence) aids early in life, while the ability to detect predators by olfactory means aids throughout. In one experiment, the effect of constant versus changing surface temperature on …

Invertebrate Fauna of the Carapaces of the Texas River Cooter (Pseudemys texana) and the Red-Eared Slider (Trachemys scripta elegans)
… texana) and the Redeared slider (Trachemys scripta elegans) at Spring Lake, Hays County, Texas. Turtles were captured from August through November 2002 using hoop nets, basking traps, and dip nets. Invertebrate samples were obtained by scraping a small area of the carapace to completely …

The mechanism and function of transient pressure fluctuations occurring in the lungs during diving in the turtle, Trachemys (=Pseudemys); scripta elegans
… voluntary dives in the aquatic turtle, Trachemys scripta elegans. LPTs were studied to determine if they could enhance pulmonary gas exchange. Skeletal muscle is the primary mechanism responsible for creating these pressure fluctuations, based on their persistence following inactivation or smooth …

Cell Cycle Regulation by Post-Translational and Post-Transcriptional Mechanisms in an Anaerobic Extremist- the Anoxia Tolerant Turtle, Trachemys Scripta Elegans
As a model for vertebrate long-term survival in oxygen restricted environments, the red-eared slider turtle (T. s. elegans) can adapt at the biochemical level to deal with hibernation occurring in oxygen-free (anoxic) cold water (<10°C). In this thesis I hypothesized that the mechanisms which …

Influence of Ultraviolet Light, Righting Response, and Community Structure in Aquatic Turtles
… bulbs on growth in slider turtles (Trachemys scripta: N = 243) from hatching to eight months of age. Growth was defined as the difference between initial and final carapace length and mass and was analyzed against treatment and row via analyses of variance (ANOVA). A significant effect from …

Invasive species: fundamental and applied science
… of four commonly traded pet turtles – Trachemys scripta scripta, T. s. troostii, Sternotherus odoratus, Kinosternon subrubrum – using Relative Invasion Risk, an adapted version of RIP that incorporates propagule pressure. T. s. scripta was found to have high impact, corroborating its now banned …

Effects of Senescence on Vascular Smooth Muscle in the Yellow Mud Turtle "Kinosternon flavescens" (Family "Kinosternidae")
… acetylcholine, a feature typical of "Pseudemys scripta" and not of mammals. Isoproterenol did not produce contractions suggesting "K. flavescens" lack beta-2 receptors or these receptors do not operate similarly to mammals. The lack of decrease in arterial responsiveness in senescent arteries …

Locomotor kinematics of turtles moving in shallow water environments
… chose different size red-eared slider (Trachemys scripta elegans) turtles to investigate their locomotion during discreet water depth, as well as during shallow water locomotion and investigated whether bone shape can be predictive of the environment they live in.
