Assembling the Neotropical Tree Flora: Andean Uplift and the Historical Biogeography of the Brazil Nut Family (Lecythidaceae) Aim The assembly of tropical tree floras is complex, involving many lineage-specific histories; however, focusing on the biogeographic history of diverse clades can reveal general patterns. We inves...

Predicting the fate of tropical forests under intensifying heat Intense droughts have caused water stress and elevated mortality for trees in the Amazon, foreshadowing the future of tropical forests as the climate changes.

This is a nice (but grim) summary of the Chambers et al. paper that I was fortunate to work on.... Predicting the fate of tropical forests under intensifying heat www.nature.com/articles/d41...

Critical part of the President's new $100,000 charge for H1-B visas: The Administration can also offer a $100,000 discount to any person, company, or industry that it wants. Replacing rules with arbitrary discretion.

Want visas? You know who to call and who to flatter.

cypress tree with 30 foot diameter trunk

Following the fantastic #ATBC2025 meeting in Oaxaca I visited the Tree of Tule, a Montezuma cypress (Taxodium mucronatum) with the world's stoutest trunk. It's highly buttressed but even after smoothing it is thicker than the largest sequoia with a smoothed diameter of 30.8 feet. #bigtrees
