Each year, I teach "Evolution of Plant Form and Function" to undergraduates - I've struggled to find good synthetic out-of-class materials - until recently. This is such a superb overview of the functional and physiological overview of land plant evolution www.youtube.com/watch?v=ZSch... 🧪🌾🌐 #botany

New study from Ty Loft’s PhD thesis. We used an energetic approach to quantify, acr sub-Saharan Africa, how mammal- and bird-mediated ecosystem functions have changed. We found that overall trophic energy flows have decreased by more than one-third, but this change varies across biomes and land uses
