Come work with me! We are hiring a Research Program & Operations Coordinator to administer a new CREATE training program and support other EEB initiatives at U of T. Please circulate to great people in Toronto looking for an academic admin position: jobs.utoronto.ca/job/Toronto-...

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! 🌐🌱🦠🧬

To the #Evol2026 folks, I am recruiting MSc/PhD students (with or without their own funding) - please send people my way if you know of anyone interested in blending ecology & evolution!

Now out in @newphyt.bsky.social, led by postdoc @usuitakuji.bsky.social with former undergrad Jerry Yu. Plant microbiomes affect colonization success in the wild!

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

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

It was fun to work on this meta-analysis of resurrection studies involving plants with Lillie Pennington, Steven Franks, Jill Anderson, and @elenahamann.bsky.social! doi.org/10.1002/ajb2...

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

"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...

New to bsky, trying to (re)connect with eco-evo folks. I'm an evolutionary ecologist who studies how rapid evolutionary dynamics shape community and ecosystem processes. My work integrates experimental evolution, population genetics, and community ecology, with an emphasis on biological invasions.

📢 New Research Alert! No organism can be the best at everything—and now we know why. A new study by our own Dr. @jasonlaurich.bsky.social reveals the hidden limits shaping evolution itself: tinyurl.com/yc8j3434 @integrativebiology.bsky.social @uofgcbs.bsky.social @joeybernhardt.bsky.social

Microbial communities can harbor many species that do not coexist in pairs, yet can coexist in the full community. Here we provide the mathematical foundations of emergent coexistence, and explain why it can't be predicted from pairwise tests journals.plos.org/ploscompbiol...

EDITORS WANTED AT ECOLOGICAL MONOGRAPHS -QUANTITATIVE ECOLOGY -THEORETICAL ECOLOGY -ECOSYSTEM ECOLOGY -EVOLUTIONARY ECOLOGY -MARINE ECOLOGY -PLANT ECOLOGY EDITORS FOR OTHER DISCIPLINES NEEDED TOO

Big congrats to former Lowry Lab postdoc Daniel Anstett, who's paper: "Rapid evolution predicts demographic recovery after extreme drought" is out in Science today. www.science.org/doi/10.1126/...

Don't miss today's Dynamic Ecology interview with @clsong.com. Jeremy wasn't lying when he wrote "Reading this is going to be way more entertaining and thought-provoking than whatever you were planning to spend the next 15 minutes doing." dynamicecology.wordpress.com/2026/03/11/i...

Thrilled to share that my first dissertation chapter is now published at Ecology! dx.doi.org/10.1002/ecy.... We embed TPCs into population dynamics to show how changing temperatures' ordering — not just its distribution — increases extinction risk (i.e. heatwaves matter!) @esajournals.bsky.social

Just a few days left to submit the ASN student research award (due March 13th)!!!! This is an AWESOME opportunity for students to get some grant writing experience!!! We LOVE reading your grants and giving feedback!!!!!!!!!!! Apply, Apply, Apply!!!!!! www.amnat.org/announcement...

In case you missed it: our review titled "Spatial structure: shaping the ecology and evolution of microbial communities" is out! 🚨 Let me hit you with some highlights on why spatial structure matters. (and why you should care!) Sharing is appreciated 🙏 🧵👇 doi.org/10.1093/fems...

New in @natecoevo.nature.com, we show that nonlinear dynamics like oscillations & chaos occur in 81% of marine fish populations worldwide. Nonlinearity was correlated with the magnitude of fluctuations & amplified by temperature variation & in fast-lived species. 🌍🌐 Link: doi.org/10.1038/s415...

Follow up to our work on eco-evolutionary dynamics of host parasite systems in complex landscapes up in Evolution @journal-evo.bsky.social. This work was done during Ruthvik's Erasmus M1 project @ruthvikpsi.bsky.social with me and @efronhofer.bsky.social. academic.oup.com/evolut/artic...

My annual "DO IT!" encouragement post! Selfishly, my time on CSEE council was the highlight of my PhD, it opened doors and opportunities that research alone did not. And I think we accomplished some good things for the society! 🧪🌎

Excited to share the first two publications from our PERSIST (Predicting Evolutionary Rescue of a Species in Space and Time) project. Thanks to NSF-DEB for supporting this work! (1/3)

Incorporating realistic ecological interactions changes our understanding of which traits are optimal in different environments, including the temperature-size rule. Awesome paper by David Anderson, outstanding former postdoc with me and Mary O'Connor.

Fabulous society. Join! And not just Canadians. The annual meeting is my favourite of all conferences and we love to have our non-Canadian friends join us.

Looking forward to the Modern Coexistence Theory workshop tomorrow. Please repost :)

Newly published in @globalchangebio.bsky.social, we look within seeds of historic herbarium specimens for changes in the prevalence of beneficial fungal symbionts in response to climate change drivers. onlinelibrary.wiley.com/doi/10.1111/...

New paper out today in Ecology Letters! In this synthesis we dive into the equilibrium assumption in ecology - why it's everywhere in ecological theory, the evidence for it in nature, when meeting the assumption is important, how to achieve it in empirical research, and more! tinyurl.com/yh6kyysm

The deadline is one week away! Don't miss out on submitting your symposium and workshop proposals 🎉

A universal thermal performance curve arises in biology and ecology doi.org/10.1073/pnas...

Fun to synthesize some exciting future directions for spatiotemporal genomics in this Tansley perspective. Check er out!

Plasticity in climate change responses - just published in Biological Reviews What in the role of phenotypic plasticity as an adaptive response to climate change? Looking at mechanisms from the subcellular to the community and ecosystem levels. With Stollewerk, @davidboukal.bsky.social, et al.

Do you like to think about temporal niches and coexistence theory? Or perhaps you want to hear some really quirky natural history of marine insects & the moon? Or both? Read on: a mystery & its potential solution in two papers!

"The myth of meritocracy in science collapses under the financial sacrifices expected at every career stage. From unpaid internships and self-funded conferences to underpaid positions, these hidden costs disproportionately exclude those without generational wealth, compounded by race and gender."

So excited to share our paper on facilitation thinking. Facilitation Thinking for Coexistence Theory - James - 2025 - Ecology Letters - Wiley Online Library onlinelibrary.wiley.com/doi/10.1111/...

maybe my favorite paper I've written, I have a synthesis out today early access in @asn-amnat.bsky.social today that attempts to answer a simple but slippery question: what is an elevational range? doi.org/10.1086/737130

Macroecological patterns in experimental microbial communities, led by Will Shoemaker & Jacopo Grilli journals.plos.org/ploscompbiol...

Preprint of our first manuscript from the PERSIST project (Predicting Evolutionary Rescue of a Species In Space and Time), with @lucasjalbano.bsky.social and many other co-authors not on BlueSky

really cool new paper showing species across the globe are NOT moving upslope any more than you'd expect based on a null model www.science.org/doi/10.1126/...

A very nice and clean test of the meta-population theory for range limits!
