Climate change is altering the geographic distributions of species and compositions of ecological communities across the globe. In nature, species interact with each other in ways that deeply affect their viability. Yet models predicting the effects of climate change on species exclude these important species interactions (e.g., competition, predation, mutualism) and only focus on direct effects of climate. This project aims to improve current predictions by explicitly adding these important species interactions into both data-driven and theoretical modeling approaches. Focal communities include breeding birds across the United States, and fish communities in Arctic freshwater lakes.
