Research Interests

The unifying theme of our lab's research is to understand how human stressors to the environment affect biodiversity and how to mitigate those impacts. These stressors include changes to landscapes, climate change, and species introductions. We often study spatial and temporal dynamics and use field studies at large spatial and long temporal scales to test theory and link ecological pattern with process. Areas of research include landscape connectivity/corridors, habitat fragmentation, plant-pollinator networks, insect community ecology, stable isotope ecology, and conservation biology. We work on a variety of taxa but have a particular fondness for insects. Settings for our field work include the longleaf pine ecosystem of the southeastern US and forests and meadows of the Rocky Mountains.
