New study from my lab! Led by prior student Sasha Bishop, along w/ co-author @johnstinchcombe.bsky.social 🌸 We performed a resurrection study on morning glory and found that within 9 years, adaptive potential declined by 96%

A resurrection experiment reveals reduced adaptive potential in a common agricultural weed

Adaptive evolution is essential for populations facing rapid anthropogenic change, yet realized evolutionary responses often fall short of expectations. Us

1. A bit of evolutionary biology. I'm really intrigued by a new perspective piece from Steve Frank that explores connections between how natural selection creates systems that generalize and recent work in machine learning about the surprising capabilities of massively overparameterized systems.

Generalization as the great leap in evolvability: insights from machine learning

Abstract. Natural selection encodes learned information in the genome. Learned solutions may be tuned specifically to past challenges, failing in altered e

My contribution to the ongoing "1%" science discourse is this picture you can send to your favourite preprint author(s) after reading their papers to tell them you liked their work! #SciArt #PawReview

I know it seems like a heretical idea, but one way to figure out if a preprint is really interesting (to you) is... to read the preprint. Then, in the spirit of sharing, send a note to authors: a simple kudos or a more detailed question. I do this a dozen times a year. It's awesome. Try it.

I’ve been thinking a lot about the shifting baseline concept as applied to everyday life. People in their 20’s now have no memory of highly functional systems, products (from blenders to sweaters) that were so well made you could hand them down across generations, or even helpful customer service.

Biological invasions are among the most pressing ecological concerns of the Anthropocene. We're pleased to present our latest #VirtualIssue: Linked plant–fungal invasions: nph.onlinelibrary.wiley.com/doi/toc/10.1... Edited by Ian A. Dickie, Marc-André Selosse and Maarja Öpik. #PlantScience

Writing a very controversial scientific paper is academia’s version of social media rage bait

Last week we had the VI International Young Researchers Conference on Invasive Species and as always it was a great conference! You can find all presentations and posters on their youtube channel, but here goes a 🧵 of the ones I liked the most. 🧪🌐 #IRYCIS www.youtube.com/@iyrcisconfe...

I’ve been experimenting with embedding a Shiny app directly inside my Quarto presentations. Instead of moving through static slides, the audience can now actively engage with data in real time. It changes the dynamic from “here’s what I found” to “let’s explore this together.” #RStats #Quarto

"Together we must reestablish the idea that older people are advocates and protectors for those beginning their careers. In an era when young people are being treated like meatware in an anonymous employment algorithm, we need to bring them all the wisdom, encouragement and connections we can."

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.

I knew Canada was angry but didn’t realize it was this bad: “more Canadians flew to overseas destinations than drove to the U.S.”

The System That Decides What Science Gets Published Is Breaking Down

The peer review system that validates scientific research is trapped in a self-defeating cycle. A new mathematical model shows why—and what comes next.

Hi all. I am very excited that after 6 years I finally got my phylogenetic comparative methods book and online exercises online. Feel free to use and share. The book is here: nhcooper123.github.io/pcm-primer/. Note that it is not finished, we had to abandon it before the sunk costs fallacy broke us
