Any forest ecology types out there have experience with "Swedish Tree Grippers"? Seriously considering acquiring some for canopy work but they are costly.

A giant in plant biology. Truly grateful for his research and influence.

Herbarium Spotlight: Tracing the Evolutionary Journey of the Brazil Nut Family | U-M LSA University of Michigan Herbarium

A recent paper by U-M researchers uncovers how these iconic tropical trees spread across South America, diversified through time, and adapted to new environments and elevations.

A landmark study following 15+ years of collaboration by researchers at the Arboretum, @duke-university.bsky.social, @harvard.edu, and partners in Mexico published this week on @pnas.org. It reveals what made the mountains of Mexico and Central America a hotspot for oak biodiversity: arb.eco/4tVWclh

Open letter for UMich profs + students to protest President Grasso's cowardly reproach of Dr. Peterson's Spring Commencement speech acknowledging those—women, Jewish students, Black students, pro-Palestinian student activists—who "refused to accept the enclosures and orthodoxies of their time."

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.

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
