Detect and predict change in refugia

My research is currently working to develop new tools to detect and predict changes in wildlife refugia. Especially in near-northern regions, new tools can be used to guide management decisions and inform policy on threatened reptiles and landscapes.

Collaborative research projects quantify and assess resilience of wildlife habitats such as those used for reproduction, overwintering, and migration. A key objective is understanding the resilience of reproductive and overwintering reptile habitat to increased spatiotemporal variability in flooding, drought, and wildfire.

Quantifying relationships between measures of reptile health and environmental conditions are necessary to understanding ecosystem and population response to multiple stressors. For this work, we use multidisciplinary techniques to monitor reptile reproductive success and winter survival in response to changes in soil moisture, soil/water temperature, and water chemistry parameters.
