I use field observations extensively and integrate understanding of revealed natural history patterns with experiments conducted in both the field and lab.

Adult wood frog

One of the clearest insights from these studies has been the realization that even a generalist species such as the wood frog that is broadly distributed over much of North America is highly sensitive to spatial gradients that can operate on scales of centimeters.  Reconciling an understanding of this small scale sensitivity with ecological success of broad geographic scales is a large part of my research focus. My current research activities are centered on understanding how suburban landscapes and associated land use impact amphibian populations.
