1 week left to get your image in for Evolution 2026 logo contest! www.evolutionmeetings.org/2026-logo-co...

UPDATE: The 2025-2026 list of faculty and postdoc positions in ecology and evolutionary biology is out! Be sure to check out this active and helpful community run resources! docs.google.com/spreadsheets...

For #FossilFriday, a visit to the Truckee Formation of Nevada: sticklebacks and a grebe in UMMP. Annual layers in these lake sediments give a precise relative chronology for fossils from different levels, providing kyr resolution essential for bridging paleontological and biological perspectives.

Brazilians at #Evol2025! @mjanuario.bsky.social and I are planning ab informal meetup tomorrow after the poster session (~7:30pm) at Creature comforts, a brewery 10 min from the conference center. Non-Brazilians who want to mingle and hear some Portuguese are always welcome!! 🇧🇷🇧🇷🇧🇷

Check out evolved on CRAN (cran.r-project.org/web/packages...) and GitHub (github.com/mjanuario/ev...)

Hope you were able to catch @mjanuario.bsky.social’s #Evol2025 talk about his evolution education package, evolved! My friends are so smart

Come watch my talk at #Evol2025 this Monday @ 9:45am, at the Phylogenetic Methods Development I section. I'll be talking about methodological considerations on inferring a complete phylogenetic tree of Canidae. Who doesn't want to hear about dogs??? (and fossilized birth-death models, obviously...)

Congrats to two paleontological recipients of the prestigious Rackham Predoctoral Fellowship: Jerónimo Morales Toledo and Sanaa El-Sayed! 🌿🐟

Here's a collage of specimens scanned and segmented at the UMMZ for the bluesky community to enjoy!

Its an honor to be awarded the ProQuest Distinguished Dissertation Award by the University of Michigan for my PhD work 🐟🧠 rackham.umich.edu/discover-rac...

It's GRFP season again, so I thought I'd share my rejection letter (from 1999!). Hang tough--it doesn't determine your future.

Went all the way to the Middle East to try for Northern Wheatear and didn't see a single one, only for one to show up in the middle of New Mexico. Probably a leucorhoa (Greenland) ssp?

Speaking as a paleontologist, we don't need to bring back species long lost to extinction. Modern ecosystems are already stressed without introducing bioengineered monstrosities. Celebrate biodiversity by appreciating & conserving the endless forms most beautiful & wonderful alive in the world today

Eric Hilton and I are busy handling other papers for this volume--keep your eyes peeled for a diverse range of contributions on fossil fishes!

Do you want to learn how to contribute to and use the Paleobiology Database? 🌎🦕🐚 Look no further - we're now welcoming applications to the 2025 edition of our introductory workshop! More details here: forms.gle/xQqDEQwwXeTH...

I love the way the paper is all "we were like WTF, why did they do that, so we tried this and OMFG. And then we figured what the hell, we should try this, and you're not going to believe this shit but....."

One week left for applications! (just a simple questionnaire).

Our datapaper "Global Roadkill Data: a dataset on terrestrial vertebrate mortality caused by collision with vehicles" is now online on #ScientificData: nature.com/articles/s41... #RoadEcology @ebdonana.bsky.social

curiosidade: se alguém criasse hoje um perfil de besouros do Brasil e postasse uma espécie única por dia, levaria pelo menos 82 ANOS para passar por todas as que conhecemos 🪲

Januario et al. found no correlation between sexual selection intensity & speciation rates or proxy traits. Because sexual selection intensity has high intraspecific variation and low phylogenetic signal, its macroevolutionary impacts are weak. Read now! www.journals.uchicago.edu/doi/10.1086/...

We are excited to share our new preprint describing the inclusion of selection models to stdpopsim, our community-maintained library with an extensive catalog of population genetic models. 1/n www.biorxiv.org/content/10.1...

Impressive magnitude of the global Holocene sea-level rise: "Our results also show that global mean sea-level rise between 11 ka and 3 ka amounted to 37.7 m (2σ range, 29.3–42.2 m)" www.nature.com/articles/s41... 🧪 ⚒️ #Geology #Geography

Our preprint is out! Kudos to @josanesousa.bsky.social, @gabrielalima19.bsky.social, @perezlouise.bsky.social and undergraduate prodigy Hannah Shof! By comparing Polypterus fin and axolotl limb we find shared and new regeneration programs. @lsuscience.bsky.social www.biorxiv.org/content/10.1...

New deadline May 15th - would love to see your contributions to this important special issue ...

Examining life-history differences among vertebrates and their mode of reproduction, Brooks et al. find that land vertebrate life histories are more constrained than aquatic ones, suggesting a wider diversity of reproductive strategies in aquatic habitats than in terrestrial ones

Does your feed need more MAMMALS?! Just in time for #2025MMM, we have what you need: All new v2.0 of the Mammal Diversity Database just launched! What's new? - Preprint on MDD2: doi.org/10.1101/2025... - Re-vamped website: mammaldiversity.org - 50,230 species-level synonyms - 6,759 species total

What can #population-level processes tell us about large-scale #biodiversity? 🧵: 1/8 A key question in #evolutionary #biology: Can we predict how quickly lineages diversify (#speciation rates) based on #traits observable at the population level? #microevolution #macroevolution

Please share this opportunity widely! Instructors: @fmachado.bsky.social @alencarlrv.bsky.social @joelmcglothlin.bsky.social Jacqueline Sztepanacz, Patrick Carter & Joe Felsenstein (virtually)

There's a small contingent of people online who get angry when you say this but: Wikipedia is unquestionably the most successful utopian project of the internet age, and its destruction would be a crime against humanity
