Insects/arthropods are powerful tools for ecological research. This session showcases research using insects as model systems, their roles in ecosystem functioning, and their use as sentinels of environmental change. We invite presentations from any disciplinary focusing on insects in ecological processes and innovative methods for studying biodiversity and environmental shifts.

Presentations:

• 2:00 PM - 2:10 PM Pacific
