Is speciation usually allopatric? Genomic analyses of 93 Drosophila species pairs show that gene flow during divergence is common—even among allopatric species—challenging the classic allopatric model of speciation. academic.oup.com/evlett/advan...

Things are pretty awful in the US right now, so I am trying to channel my nervous energy into creative and educational things... So I'm designing a new geoscience education game for my freshman class. It's a quick play card game about the geological timescale... Anyone want to play this semester?

Another responses to the recent sponge/ctenophore paper in Science. . .also worth a read!

👇 Exciting post-doc with a fantastic PI!

We are raising funds to help support international students attend our next conference. If you are able to donate, any amount, is greatly appreciated. Details can be found here: www.dropbox.com/scl/fi/hziez...

It was great to meet so many other Early Career Researchers at our #TIBS2026 mixer last night - both catching up with old friends and meeting new ones. To celebrate all the ECR Biogeographers, we have created a starter pack so you can follow all the exciting work being done: go.bsky.app/KvnmdnK

Come join me in Canada 🍁! I'm recruiting a funded PhD student for fall 2026. My lab answers questions about how snails actually grow their shell using evo-devo techniques. More info: artsandscience.usask.ca/profile/NWeb...

I am still optimist, but...

Sponges are notoriously difficult to understand in evolutionary biology terms. I think this paper is a big step forward : www.science.org/doi/10.1126/...

This delicate sponge has a remarkably clever survival strategy.🪝✨️⁠ ⁠ Most sponges filter small plankton and bacteria from the water and pump them through their bodies. But the harp sponge (Chondrocladia lyra) uses small hooks along its vertical branches to trap and eat larger prey.

I look for a New Years Bug as a little omen of the year to come - finding an Embiid (webspinner) is VERY good. I didn't know about webspinners until I became an entomologist, and this one was found in my childhood backyard! 2026 is the year of the little dudes who get overlooked #bugsky 🧪

I'm looking for postdoc positions in freshwater biogeochemistry! Interested in any projects investigating nutrient and carbon cycling, phytoplankton coupling with dissolved organic matter cycling in human-altered landscapes, or hydrology and spatial modeling!

So happy to see this published! Led by the very talented @marinamoser.bsky.social who also did all the line drawings, a valuable and increasingly rare skill. Congrats team!
