Research Interests
Our lab primarily focuses on understanding how human-induced stressors impact biodiversity and exploring ways to reduce those effects. These stressors include landscape changes, climate change, and species introductions. We often study spatial and temporal dynamics, using field studies at large spatial and long temporal scales to test theory and link ecological patterns with processes. Areas of research include landscape connectivity and corridors, habitat fragmentation, plant-pollinator networks, insect community ecology, stable isotope ecology, and conservation biology. We study a range of taxa, but especially insects. Settings for our fieldwork include the longleaf pine ecosystem of the southeastern US and forests and meadows of the Rocky Mountains.
