Global Change Biology

Action Groups

The IGCB supports two Action Groups, which are university think-tanks that address critical global change issues.

Action Groups bring together key disciplines and interdisciplinary research teams to facilitate multifaceted research, enabling science-based decision-making frameworks for management of natural ecosystems and human-dominated systems adversely impacted by global change drivers. Action Groups involve scholars from across campus with a passion to address key issues in global change biology.

IGCB Action Group: Characterizing the magnitude, time course, and risk factors of pollen-associated health effects in the industrial Midwest in a changing climate


Goal: To inform future efforts and grants to characterize the present and future burden of pollen-associated health effects and design interventions to reduce pollen-associated health effects.

Blue Bird

IGCB Action Group: Predicting the limits to adaptive shifts in range and phenology in migratory birds

Goal: To understand the consequences of warming-induced changes in body size and allomentry for migratory species’ abilities to track recent and forecasted changes to the spatial distribution and phenologies of their resource bases.
