New paper out! Limited evidence that butterflies are capable of changing their thermoregulatory performance or thermal tolerance in response to local climatic conditions. Instead, poorer thermoregulators have shown stronger upwards elevational range shifts in response to climate change rdcu.be/fuSJE

Butterflies with low thermoregulatory capacity show greatest upwards range shifts along an elevational gradient

Communications Biology - Lack of variation in thermoregulatory capacity or thermal tolerance in butterflies across an elevational gradient suggests limited adaptive capacity. Poorer...

I am incredibly thrilled to announce that I will be starting as an Assistant Prof at Yale EEB in January 2027!! 🎉🎊 Stay tuned for student and postdoc openings, and please feel free to reach out to me if you are interested in eco-evo, range dynamics, species interactions, and global change! 🌐🌱🦠🧬

For colonization success, should hosts 🌱 and microbes 🦠 travel alone, together, or swap partners along the way? Excited to share a new paper with Jerry Yu and @mfrederickson.bsky.social in which we test how microbial partners alter plant performance upon natural introductions: tinyurl.com/8u4268n6

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 .

General Predictions for the Effects of Warming on Competition

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....

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

Many biotic interactions occur via chemical compounds released in the environment. Here the authors review the field of chemical ecology & discuss the importance of investigating landscape-scale chemodiversity as an emergent, dynamic property of biological communities www.nature.com/articles/s41...

Canada’s ‘major projects’ should not come at the cost of the environment

What an incredible new paper out today in @science.org, led by Frederickson Lab member @usuitakuji.bsky.social (from his PhD work with Amy Angert)! Competition increased adaptation to warming across replicated miniaturized "landscapes" using duckweeds as a model plant community

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: tinyurl.com/3j8s9t8b

Competition enables rapid adaptation to a warming range edge in a model plant community

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...

"The need to transition towards a clean energy future demands investment in new infrastructure. However, the way to do it is not to hollow out the scientific processes designed to safeguard communities and the environment." 🌎 theconversation.com/canadas-majo...

Canada’s ‘major projects’ should not come at the cost of the environment

Impact assessments prevent harm before it occurs. Circumventing the process before we understand the risks is misguided and a gamble with our collective future.
