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.

Happy to share this commentary on our new paper in @pnas.org, led by William Farhan-Rios, exploring responses of tropical tree communities to climate warming from the Amazon to Andes Mountains 🌴 ⛰️ 🌐 An uphill struggle for tropical forest trees | PNAS www.pnas.org/doi/10.1073/...

Excited to share a new paper! "Sorting of ancestral polymorphism and its impact on morphological phylogenetics and macroevolution". Part of some work I've been doing on modelling the evolution of polymorphic traits in fossil echinoderms. academic.oup.com/evolut/advan...

MSU Plant Bio is hiring a new herbarium director! Our herbarium is a wonderful resource on campus and I'm excited to have the opportunity to make it even better by bringing in a new director. Details here: plantbiology.natsci.msu.edu/job-postings...

Come join us in Corvallis! Great colleagues, a wonderful location for plant science of all types, with the added benefit of the beautiful surroundings of Oregon!

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

Herbarium director position opening at Oregon State University ‪@osu-herbarium.bsky.social‬ Great opportunity for herbarium- and field-trained botanists at any rank. bpp.oregonstate.edu/bpp/about/op...

Heading to Oaxaca for #ATBC2025 ? Make sure you stop by our symposium for all things leaf temperature, heat tolerance, and tradeoffs across climate gradients 🌿💧🌡️

#NExTropics symposia at #ATBC2025 find out the latest from nutrient addition experiments from across the tropics

#ATBC2025 started. More than 1000 participants are in the room.

I'll be talking about hyperdominant tropical tree species at #ATBC2025 in #Oaxaca, including some recent work on Eschweilera coriacea, which despite being possibly the most common tropical tree in the world (~5 billion trees in the Amazon basin) can be hard to identify and is poorly studied.

To Whomever vandalized the Peony Garden at the Nichols Arboretum at the University of Michigan in Ann Arbor last night: There is so little beauty in our world right now. You are making the world a more cruel and ugly place. You are not helping. www.instagram.com/reel/DKXFSz5...

This is an absolute disaster. If we don't stop this, they will turn NSF into a pawn of the Trump administration. There will be no research on climate, biodiversity, or anything that isn't eugenics or AI or how to more efficiently destroy the planet for profit. This cannot be allowed to happen.

The legendary USGS Bee Lab is being shut down. The 2026 budget proposal defunds the Ecosystem Mission Area, which supported the lab. If their science helped your work, there’s still time to make your voice heard. Read below. (1/4) 🧪 #pollinators #Pollinators #USGS #Entomology #Hymenoptera 🪲🪳

I continue to be awed by the Blanding's turtles at the ES George reserve #ESGR. A U-M grad student first tagged them in 1953. At 95 years old, our oldest marked female shows no sign of aging and reproduces with as much vigor as a 20 yr old! lsa.umich.edu/herbarium/ne...

Fully on board with dems running for office promising to reinstate fired federal employees and jail this administration’s various criminals, but let’s go ahead and add “we will seize by eminent domain any national parkland sold to developers”

Thais Vasconcelos @tvasconcelos.bsky.social will be the new Director of the Univ. of Michigan Herbarium starting in January -- and the first woman to fill this role in our herbarium's >100 year history. Congrats Thais!

Finally catching up with the hard copy of @andrewlhipp.bsky.social's latest. Beautiful book! A meditation on oaks--and what they tell us about ecosystems, evolution, and Earth history.

finally read the small print in this poster-- #botany power!

Osculate is a literary word meaning to kiss. Inosculate is when two trees accidentally become grafted to each other and exchange sap. Our #WoodyPlants class found this pair of osculating maple trees near Milan— note the smaller tree is so well fed that its trunk is larger above the graft. #botany
