Very sorry to hear this and for your loss. I met him once in a GRC where he presented his very important paper on African cichlids. Excellent presentation, and he was very welcoming. My deepest condolences to his colleagues and family.

Are you (or do you know someone) recently graduated from undergrad looking to beef up your skills and experience prior to starting grad school/career? Do you like social drama and parakeets? Come join my team! I'm looking for two people to start very soon!! tinyurl.com/59rf8jcy

An angiosperm‐wide perspective on reproductive strategies and floral traits Flowering plants have many modes of sexual reproduction, notably varying from selfing to outcrossing, and from bisexual flowers to individuals with separate sexes (dioecy). These reproductive modes ...

New paper showing clustering of the many traits across reproductive strategies of angiosperms. Lots of interesting discussions that gave raise to this piece. But only possible thanks to the hard work of Andrew Helmstetter, Sylvain GlΓ©min, and Jos KΓ€fer.

Came to #ssb2026 for the original chicken figers and to pet the most adorable yellow lab ever #RocotoManzano.
See you this afternoon in the "Rev the Bayes and Q the matrix" workshop, get ready for graphical models, math, and trait evolution!

I understand the need for documentation, but a lot could be clarified simply by speaking directly to an administrator. This gives me flashbacks of trying to claim mileage from a trip and getting into a loophole because the typical road was closed due to landslides = 4 meetings totalling 3 hours.

Check out our review/perspective piece on phylogenetic diversification analysis, intended for the 75th anniversary of

This is a small review of recent diversification methods (for molecular phylos), what they have achieved, their challenges, and a small opinion on where they are going. We are hoping this is useful for people trying to understand the myriad of methods available.

Really good summary of our work on poricidal anthers! I am printing this phylo in a big poster!

This work is the result of a lot of persistence, my co-authors especially @draverbee.bsky.social and @nicrodemo.bsky.social, greatly improved by reviewers and handling editors. Poricidal anthers evolved multiple times but this phenotype stayed in lineages 50 my after the origin of all angiosperms.

Series B: Biological Sciences Data from palaeontology and biodiversity suggest that the global biota should produce an average of three new species per year. However, the fossil record shows large variation around this mean. Rates...

It's outdated in so many ways but Sepkoski's 1998 Rates of Speciation in the Fossil Record is such a classic and highly influential paper

I'm a little bit late, but happy to see this new paper led by @imillercrews.bsky.social and anchored by @rosvall-lab.bsky.social now out on bioRxiv.

G.G. Simpson is the most mentioned paleontologist at #eseb2025. These are 3 different talks from two separate sessions. But there are more! adaptive landscapes, adaptive radiations and horotely (rates) are in! So is the fossil record! @roszenil.bsky.social @ignacioq.bsky.social and others!
