I look forward to the first partridge phylogeny rendered in PearTree.

So I pleased to announce the conceptual spawn of FigTree: PearTree (acronym still to be finalised). If you want to dive right in it is hosted as a web app here: artic-network.github.io/peartree (click the “Example...” button for immediate candy and then click every button you can find).

Register for Theory across Biology 2026: 12 June, Bern.
One-day meeting on mathematical & theoretical approaches in biology with chalk talks and flip-chart sessions. Ideal for theorists, modelers, and interdisciplinary biologists.

Reposting this because I'll never pass up an opportunity to introduce people to the wonderful world of sheoaks.

To be clear, this is family of ANGIOSPERMS with feaux needles/cones most closely related to BIRCHES.

Oh, and they also fix nitrogen to boot! Then again, so do the closely-related alders.

seminar announcement with photos of speakers and talk titles

The integration of speciation seminar series is restarting, with the first session coming up on *Tuesday March 3rd @ 5pm CET*, featuring two talks by @naturalselection.bsky.social and @andreaestandia.bsky.social + career Q&A with @markravinet.bsky.social as part of the ECR in Speciation theme.

A covarion model for phylogenetic estimation using discrete morphological datasets Abstract. The rate of evolution of a single morphological character is not homogeneous across the phylogeny and this rate heterogeneity varies between morp

Our new paper 'A covarion model for phylogenetic estimation using discrete morphological datasets,' is out in SysBio!
We introduce the "covariomorph" model in RevBayes to capture character and lineage specific rates of morphological traits.

Excited to share our new paper in @natcomms.nature.com We synthesize causal discovery & inference approaches across traditions (regression adjustment, quasi-expts, SEMs, Granger causality, convergent cross-mapping, and more) into a unified workflow for ecologists. www.nature.com/articles/s41...

I'm not really big on awards in academia but my students got together and put in a successful nomination packet to give me an outstanding mentor award from my college and it's the most meaningful and humbling recognition I've received in my career. 🥹

"Palaeontology is a science and these days you need some maths and computer skills and the more the better...[which] will be of far, far more use to you at university and beyond in a career than learning the names of dinosaur species or the exact age of a given formation."

I worked on euphorine braconids for my PhD but I haven't really touched it since, so it was nice to be included and help contribute in this updated version of the dichotomous key. Hope it will be useful to people as the old version was to me.

Taxonomy and phylogeny are two sides of the same coin, but that doesn't mean they are always in agreement. I wrote a blog post on why the new Phylogeny Explorer in @birdsoftheworld.bsky.social is such a big deal in that regard, and what's in store next for us.

This Research Experiences for Undergraduates (REU) program is funded by the National Science Foundation to create "points of entry" for students interested in research. Students apply from across the country to spend 10 weeks in Bozeman, Montana this summer (May 26, 2026 - August 1, 2026). Admitted students are paired with a faculty mentor, who serves as an advisor for a student's summer project. Each student receives a stipend ($7000 for 10 wks). Travel compensation, room, and board are also provided. Our program leverages MSU’s unique microbiology expertise, focusing specifically on microbes living with little or no oxygen (like those in the hot springs of nearby Yellowstone). Low oxygen microbes are essential to human and ecosystem health. They influence (or control) such processes as the breakdown of food in the GI tract, removal of toxins from our bodies and the environment, and production of greenhouse gases. They are also models for understanding the origins of life on this planet, and the potential for life on other planets. A key goal of our program is to recruit students from schools with limited research infrastructure. Being in Montana, a state with a vibrant Native American community, we are particularly interested in applications from students at tribal colleges. However, ANYONE with an interest in microbiology - or biology/science in general - can and should apply. If willing and able, please share/tweet/spread the word far and wide. Applications are due February 14, 2026. Full details can be found through our website http://www.montana.edu/mbi/reu/

Friends, please help spread the word about our microbiology REU program at Montana State University.

How many different trees can be generated by just one duplication event? It turns out A WHOLE LOT, if you consider the coalescent process.

Our new paper is online! We found that 1) today's shark & ray diversity was already reached ~100Ma; 2) that the K/Pg extinction was not catastrophic; 3) that the max diversity was reached ~50Ma; and 4) that today's diversity is depleted compared to the past.

As we all settle back in at home after an amazing #ssb2026 in Baton Rouge, it seems fitting to share this recent pub from @mbomaaaron.bsky.social where he writes about the utility of taxonomic education. Aaron was a @systbiol.bsky.social mentee and so it is very exciting to see this work of his out!

Very excited for this incredible lineup of talks at #SSB2026!
