Functional traits underlying species distributions



in Ecological Monographs and Ecology Letters

​  
​     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 incorporates physiology and biophysics into simulation-based models to identify the mechanisms that determine a species geographic range. I have primarily used these methods to identify the importance of water loss physiology in structuring the geographic range of salamanders. These approaches can then used to answer questions about the ecological impact of climate change. Read more here.

Plastic responses to environment




in Ecosphere and Functional Ecology

   
​    Animals can adjust their physiology in ways that helps them live in different environments. My research explores the potential for animals to adapt or acclimate to stressful environments by adjusting physiological traits. I began studying geographic variation in water loss rates in salamanders to identify whether salamanders could reduce water loss rates in drier climates. My studies suggest that salamanders are very capable of acclimating to their environment by adjusting water loss rates and metabolic rates in ways that improve their ability to tolerate harsh climatic conditions. Further studies like these will help to make more realistic predictions on the capacity to avoid extinction under climate change. Read more here.
