Excited to share our new paper in which we test how competition alters adaptation at a warming range edge @science.org
We find that competition can increase adaptation to warming when there is a shared evolutionary response to both biotic and abiotic drivers of selection:

New #ecoevo paper @pnas.org: Evolution of species’ range and niche in changing environments. I show that feedback between evolutionary and population dynamics can create a tipping point where genetic variance erodes, and species’ ranges contract or fragment www.pnas.org/doi/10.1073/... #popgen 🧬🧪 🌎
New paper out today in Ecology Letters! We use Modern Coexistence Theory and Metabolic Theory to get general predictions for the effect of temperature on competition. Led by brilliant postdoc @kaleighedavis.bsky.social and @joeybernhardt.bsky.social, with Po-Ju Ke, Patrick Thompson and Mary O'Connor

What have we actually learned from empirical applications of Modern Coexistence Theory? We reviewed 84 studies from the last two decades to find out. Read our new synthesis in Ecology Letters here:

Why we’re concerned about “Getting Major Projects Built in Canada” 👀 and its impact on nature and a healthy environment. Have your voice heard - read the govt’t proposal www.canada.ca/en/one-canad... and email feedback to [email protected] by June 7, 2026 🙏@baumlab.bsky.social
Excited to share our new paper: Predictions from evolutionary theory for urban environments. We brought together empiricists and mathematical theorists to find common ground on where and how we can work together to better understand urban evolution onlinelibrary.wiley.com/doi/abs/10.1...
Most predictions of whether populations will adapt to warming range edges ignore species interactions. We experimentally tested whether range-edge populations can adapt to warming within a competitive...
Been waiting for someone to write a paper on expectations of how warming impacts Lotka-Volterra-type competition! A great example of how revisiting a classic derivation (consumer resource -> Lotka-Volterra competition) with slight modifications can yield interesting findings. Excited to read it :D .
We combined two major theories in ecology to investigate whether warming may have general effects on competition for shared resources. We found that species' niche and fitness differences both decrea...
Urbanization drives rapid and extreme environmental change, profoundly shaping the ecology and evolution of populations. In this Perspective, we call for the integration and development of evolutiona...

Preprint finally out! I show that eco-evo feedback can drive a tipping point where genetic drift overwhelms adaptation. This can result in a contraction of a species' range border or range fragmentation. Fragmentation is abrupt and arises readily under rapid temporal change. doi.org/10.1101/2025...
