Corticosterone secretion in response to capture and handling in free-living red-eared slider turtles.

Effects of exogenous corticosterone on locomotor activity in the red-eared slider turtle, Trachemys scripta elegans.

We investigated the effects of exogenous corticosterone on the locomotor activity of captive red-eared slider turtles, Trachemys scripta elegans. An increase in plasma corticosterone often increases locomotor activity in mammals and birds, but there are no reported findings for turtles. In this study turtles implanted with corticosterone-filled Silastic((R)) implants showed a significant increa...

Estradiol and incubation temperature modulate regulation of steroidogenic factor 1 in the developing gonad of the red-eared slider turtle.

Red-eared slider turtles are genetically bipotential for sex determination, with incubation temperature of the egg determining gonadal sex. At higher incubation temperatures, females are produced, possibly due to increased biosynthesis of estrogen. Exogenous estrogen causes the formation of ovaries, and prevention of estrogen biosynthesis results in the development of testes. In mammals, steroi...

Prevalence of Gastritis and Enteritis in Red-Eared Turtles Diagnosed by Radiology

Objective: Recently, Red-Eared turtles are kept as pets in Iranian houses; however, because of lack of knowledge about their caring, they are in risk of lots of diseases.  Turtles of all ages should be fed with a diet that contains a wide variety of both animal and plant based items but they are usually fed by one item diet which may make gastrointestinal (GI) sickness. They are also several ba...

Stable Isotopes of C and N Reveal Habitat Dependent Dietary Overlap between Native and Introduced Turtles Pseudemys rubriventris and Trachemys scripta

Habitat degradation and species introductions are two of the leading causes of species declines on a global scale. Invasive species negatively impact native species through predation and competition for limited resources. The impacts of invasive species may be increased in habitats where habitat degradation is higher due to reductions of prey abundance and distribution. Using stable isotope ana...
