The PhUnFETTy lab will have four presentations at #ESA2025. These will cover plant ecophysiology, trait ecology, eutrophication, water availability, mycorrhizae, demography, theory, modeling, and more!
Check out the flyer and replies below for more details. Hope to see you in Baltimore!

This work (w/ @alissarcheaib.bsky.social) explores the power of traits to predict plant population growth as expected from components of Eco-evolutionary optimality theory. The results are new and exciting and I would love to chat with y'all about them!
