I don’t get a lot of opportunity to share the peacock-turkey battle photo I took last year, it looked like a dinosaur showdown:
New paper by Ph.D. student Melvin Vankelst in Proc B. We modified our semi-automated high density 3D geometric morphometrics protocol to fit carnivoran molars, and test the shape-diet links of these teeth. Check it out! @universitedeliege.bsky.social royalsocietypublishing.org/rspb/article...
Decoupling geometry and topography reveals contrasting ecomorphological signals in carnivoran carnassial teeth
Abstract. The lower carnassial tooth (m1) is a key innovation underlying the ecological diversification of Carnivora. However, their exceptionally diverse

Velvet worms shoot rapid-hardening glue at their prey (other invertebrates). Within seconds, the sprayed liquid hardens to plastic-like consistency, trapping or slowing the target. This marvelous glue has possible human applications in recyclable bioplastics & surgical sutures that dissolve.

I appreciate all the love for my previous post, so, here's a little more velvet worm / Peripatus cuteness to start your weekend off right! Beneath that adorable little eye, you can see the stumpy glue cannon, which it uses to subdue prey! #Macrophotography #TheWorldBeneathOurFeet 🧪
It's Trilobite Tuesday! Trilobites, while commonly seen fossilized as single individuals, were highly social animals—gathering together to mate, molt, or feed. On occasion, fossils are unearthed featuring multiple trilobites on a single slab, like these ornate 1-in- (2.5-cm-) long Devonian lichids.
Whew... my student's acknowledgement section of their thesis just made me cry.
Dear microbiome enthusiasts: I'm excited to be moving my lab to New York University this fall (& the NYU Institute for Engineering Health); with joint-appointment @isbscience.org I'm hiring a postdoc @ NYU to look at diet-driven evolution in the gut: apply.interfolio.com/189980 Please share! 🦠🤓

Who at #botany2026 is thinking about which talks to see tomorrow? Maybe I humbly recommend our talk on Physalis phylogenomics where we ask the question, why are there so many tomatillo species 50 million years after a (famous to Solanologists) bottleneck? Tomorrow 1:30pm in San Ignacio!
🚨NEW PAPER 🚨 "Deconstructing empirical fitness seascapes across scales of granularity" published in #G3 (@genetics-gsa.bsky.social) 1/2 The fitness landscape has been among the most influential instruments in evolutionary theory for nearly a century. But we often treat them as fixed and static.
I'm looking for PhD student to join my lab at the University of Arkansas at Little Rock (Fall 2027)! If you're interested in evolutionary genomics, conservation genetics, or biogeography, please reach out. I'll also be at #AOS2026 this week talking about sexual selection in small populations.

This Film often has the piss taken out of it for being a rather sedentary piece about 2 people just talking a lot — BUT — it has one of the most brilliantly prescient monologues in the history of Movies imho. MY DINNER WITH ANDRE (1981) Have a listen.
Okay, I am going to tell a little story. It's one I have saved for the last couple years, almost nobody knows about it. But it lives in my heart. I don't know how others will feel about it, maybe something, maybe nothing. It's about the Uncanny X-Men. 1/
Major #Botany2026 FOMO, but the drive MA->OR starts this week. So, sharing from afar: I’m recruiting grad students for my new lab at OSU! Info: www.mckenzie-lab.org . We're going to have FUN with systematics, speciation genomics, methods, natural history, and more in North Am angiosperms. Reach out!

Sympatric species often exhibit permeable reproductive barriers, yet many of them coexist as phenotypically distinct entities. One way to account for this apparent paradox is that selection on loci th...

I've been to _tiny_ conferences (n~30). I've been to HUGE conferences (n>1000). I've been a conference focused on a single species. I've been to ornithology, paleontology, methodological, and various evolution conferences. But I've never been to a Botany conference. I feel I missed out :/
Wanna hear about introgression and pollination syndromes? Boy, do I have a talk for you! I'll be presenting my last dissertation chapter in the Cooley Award session on Monday, 8:45am in room Tucson C-D! #botany2026
