Check out this new pre-print that covers a survey-based study of Plant Awareness Disparity! This work was led by undergraduate researcher Ari Hoffman, who was supervised by my postdoc advisor @TNCVasconcelos and me:

Our new pre-print (with @erichagen.bsky.social, @latinorchidbot.bsky.social, @jameswclark.bsky.social , Elizabeth Forward and Nick Priest) reveals rapid pollinator evolution in orchids, but no clear impact on diversification. Perhaps pollinator specialisation is not such a powerful force. 🐝🌱

Polyploidy Webinar 2 April 2025 YouTube video by Mike Barker

The recording of last week's #PolyploidyWebinar featuring @raymondcast.bsky.social and @erichagen.bsky.social is now up! youtu.be/zmUyTO3jN6s

A flyer for the next Polyploidy Webinar on Wednesday, April 2, at 11 AM PDT. Featuring Raymond Castillo from Washington University presenting "Phylogenetic methods for modeling chromosome size and count" and Eric Hagen from the University of Toronto on "Using -SSE models to study diversification after neopolyploidy and paleopolyploidy"

Join us on Wednesday, April 2 at 11 AM Pacific Time for the next #PolyploidyWebinar! The last webinar of the 24-25 season will feature @raymondcast.bsky.social and @erichagen.bsky.social! Sign up (if not already!) to get the zoom: www.barkerlab.net/polyweb

It's here and ahead-of-print at @asn-amnat.bsky.social ! 🎉 Our 22-page polyploid coexistence model is now available: doi.org/10.1086/734411

This work wouldn’t be possible without NSF support—including funding from an NSF GRFP, an NSF PRFB, and NSF DMS & DBI grants. @soltislab.bsky.social l

🚨New #phylo paper alert!🚨 🌲+🔥= speciation? This one has been a bit of a journey, but thanks to lead author Dan Turck's expertise on #conifers it has turned out as quite the treasure-trove of conifer evolution! (reading-access link on my website)

Conceptual diagram of historical biogeographic patterns expected to be observed under the ‘centers of arrival’ hypothesis (on the left) and the ‘centers of polyploidization’ hypothesis (on the right). Under the ‘centers of arrival’ scenario, polyploidization occurs across the globe but is followed by higher rates of antiequatorial movement relative to diploids. Under the ‘centers of polyploidization’ scenario, we expect to see higher rates of polyploidization in poleward environments.

a potential nasty consequence. these are profile likelihoods for a default model (b/d) and a more model (a/c). (b/d) is what you'd get fitting a standard Pagel model with ARD. You get these horrible likelihood ridges for parameter estimates (e.g., b. theta4). But for the same dataset, there is a slightly non-standard model (non-standard in the sense of it's not ER/SYM/ARD) that has really nice statistical behavior

I wrote this about finding the optimal discrete character model structure. I hope this will be useful for empiricists. The main point is that relying only on the package default models is bad and can have nasty consequences or parameter estimates and ASR.
