Vertebrates respond to seasonal changes and environmental stressors by modulating their circulating glucocorticoid levels. Fluctuations in glucocorticoids alter various aspects of an organism's physiology and mediate behaviors such as appropriate rea

The mechanisms that mediate the interaction between the thermal environment and species ranges are generally uncertain. Thermal environments may directly restrict species when environments exceed tolerance limits (i.e. the fundamental niche). However

Many wild animals are subjected to anthropogenic stressors in the form of direct human disturbances from recreational activities. However, for many species it is unknown how these stressors affect individual fitness and behavior. We tested whether pa

Historically, egg-bound reptile embryos were thought to passively thermoconform to the nest environment. However, recent observations of thermal taxis by embryos of multiple reptile species have led to the widely discussed hypothesis that embryos beh

Maternal stressors can play an integral role in offspring development and ultimate behaviors in many vertebrates. Increased circulating stress avoidance hormones can be reflected in elevated concentrations in ova, thus providing a potential mechanism

Tissue samples used for genetic analyses are increasingly necessary for proper management of rare or endangered species, yet growing evidence suggests that traditional methods used to sample or mark amphibians have detrimental fitness effects. We use

Although many turtle species are exposed to anthropogenic stressors, how these stressors impact circulating stress hormone levels in these species is widely unknown. I compared circulating levels of corticosterone in two populations of painted turtle
