Benning Lab
Department of Ecology and Evolutionary Biology
Cornell University
Our research group seeks to understand the interplay between evolutionary processes and ecological patterns. We’ve worked on things like
- the importance of biotic interactions in constraining species’ geographic distributions
- the role of temporal gene flow in constraining rapid adaptation
- how environmental gradients control the spread of biological invasions
- how temporal environmental variation mediates the formation of species’ range limits
We make use of manipulative field experiments, long-term observational data, controlled laboratory experiments, and theoretical models to gain a more complete understanding of the mechanisms underlying ecological and evolutionary patterns.

New preprint: Expansion load reduces fitness at the range margin of an invasive plant, with Ryan Briscoe Runquist and Dave Moeller. Across a ~150-year invasion chronosequence in common tansy, drift — not adaptation — dominates: range-edge populations carry expansion load and show reduced fitness.

Farewell and thank you to Anna Cohen, our first lab manager, whose last day is today. Anna built this lab from an empty room. We’ll miss her!
