Finally! Here is our perspective on why cooperation maximizes diversity and how it promotes additional coexistence mechanisms that do not occur under competition journals.uchicago.edu/doi/abs/10.1... This is a hard topic with strong opinions... Thanks @asn-amnat.bsky.social for publishing it! 🧵👇

Our paper on how to use niche theory (MacArthur's minimization principle) to understand eco/evo limits to diversity got a shout out from Quarterly Review of Biology: www.journals.uchicago.edu/doi/10.1086/... The paper is hard to access but a copy can be found here drive.google.com/file/d/14EGZ...

#PhD Position: Interested in the evolutionary and ecological impacts of whole genome duplication? Join Dr. Tia-Lynn Ashman @drtialynn.bsky.social and I at the U. of Pittsburgh, to test what drives the competitive outcomes between diploids and #polyploids Details: shorturl.at/nQ8UW

In community ecology, this is called the "Appendix XVII of a Peter Abrams paper" effect

🚨postdoc opportunity at UBC🚨 applications are now open for the Killam Postdoctoral Fellowship, due internally Oct. 15 - www.postdocs.ubc.ca/award/killam... I can nominate 1 person and give feedback on that nominee's materials - if interested plz email me by Sept. 10 - join us!

Our special feature/passion project at AmNat, "Demystifying fundamental theories in ecology", co-organized with @sebastianschreiber.bsky.social is out now 🤩 www.journals.uchicago.edu/toc/an/2025/...

New special feature available ahead of print! Jawad Sakarchi & Rachel M. Germain break down MacArthur’s consumer resource model with insights on the mechanistic understanding and biological intuition of how competition and coexistence operate. www.journals.uchicago.edu/doi/10.1086/...

Today, I am excited to share our new paper in The American Naturalist’s (@asn-amnat.bsky.social) special feature: Demystifying Fundamental Theories in Ecology. Check out “MacArthur’s Consumer Resource Model: A ‘Rosetta Stone’ of Competitive Interactions.” doi.org/10.1086/733516 DM for a copy!
