Climate Change


In recent years, I have become more involved in climate change research given its potential to have large impacts on ecosystem processes. My lab is working in conjunction with other labs in our department to examine various effects of climate change at Whitehall Forest and Coweeta LTER. We offer a year-long undergraduate program, "Investigating and Modeling the Potential Effects of Climate Change on Ecological Systems," that will involve the cooperation of several of my graduate students to intergrate their longer-term research with summer coursework designed to teach undergraduates how to design ecological field experiments. In addition to designing field experiments, students will learn how to develop and test predictive models, estimate model parameters, assess model fit, and improve models using adaptive feedback. This is a rare opportunity for undergraduates to become intimately involved in climate-change research.

Many of the effects of climate change on birds are largely unknown; however, there is a growing body of research that indicates birds are already being affected by warming temperatures and seasonal shifts. For example, arrival times on the breeding grounds are advancing and this may lead to asynchrony between prey availability and food sources required for nesting. Additionally, warming at higher elevations could lead to large shifts in species' ranges or elimination of suitable habitat for species that require habitats at higher elevations. Understanding the potential impact of climate change can guide conservation strategies to ensure the persistence of many of the species that may be affected by changing global climate.
