Using water loss to improve mechanistic species range models
in Ecological Monographs

​  
​     A fundamental problem in ecology is to explain the uneven distribution of a species through space and time. To tackle this problem, ecologists use species range models to understand where and why organisms are found in certain areas. My research focuses on improving these methods by adding realistic physiological traits and biophysical processes involved in water loss. The project has demonstrated that the microclimates that surround all organisms, termed the boundary layer, can improve the predictions made by species range models. I use a combination of empirical and theoretical approaches to identify the best approaches for modeling the ecological impact of climate change. Read more here.

Geographic variation of water loss rates suggest salamanders respond to climate
in Ecosphere

   
​    Animals can adjust their physiology in ways that helps them live in different environments. I studied variation of water loss rates within abundant, fully terrestrial salamanders in the Blue Ridge Mountains to understand how salamanders respond to warm, dry environments. The project found that the Southern grey-cheeked salamander (Plethodon metcalfi) and the Southern Appalachian salamander (P. teyahalee) adjusted water loss rates to compensate for warm, dry environments throughout their elevational range. Lower water loss may improve habitat suitability by increasing the amount of time that salamanders can be active in their environment. Read more here.
