Information about demographic rates and habitat use are crucial for effective management and protection of species-at-risk. Demographic rates are integral to assessing population viability, identifying causes of endangerment, and quantifying the effects of recovery actions, while identifying critical habitat is key for informing regulatory tools designed to protect species-at-risk. Despite the importance of demographic and habitat information, lack of knowledge about these variables can often hamper conservation efforts, especially in amphibians. Amphibians have been in an alarming state of decline for decades and are currently one of the most vulnerable taxa globally. Delays in protection and conservation of amphibian species are often attributed to lack of basic species knowledge, including population demographic data. For my MSc, I am investigating survival and movement of the endangered Jefferson salamander (Ambystoma jeffersonianum) and their unisexual dependents (A. laterale-(2) jeffersonianum) to provide baseline information for conservation management.
