In Baños-Ecuador studying this colourful population

We just published a first exploration using whole body RNAseq of the mechanisms shaping color variation in Gasteracantha. More work to come — stay tuned! onlinelibrary.wiley.com/doi/10.1002/...

Hi all. I am very excited that after 6 years I finally got my phylogenetic comparative methods book and online exercises online. Feel free to use and share. The book is here: nhcooper123.github.io/pcm-primer/. Note that it is not finished, we had to abandon it before the sunk costs fallacy broke us

This looks neat, actually does a formal analysis of what I've suspected for a long time -- ΔK is an odd way to decide number of pops. H/T @biologyjoe87.bsky.social for the paper. (Personally I think K=0) www.biorxiv.org/content/10.6...

I'm teaching Statistical Rethinking again starting Jan 2026. This time with live lectures, divided into Beginner and Experienced sections. Will be a lot more work for me, but I hope much better for students. I will record lectures & all will be found at this link: github.com/rmcelreath/s...

We decided to put this one out before the end of the year "Gene expression and structural differences underpinning black and white colouration in spiders" ecoevorxiv.org/repository/v...

🚨Two funded PhDs on the evolutionary ecology of antipredator colouration 🦋 with myself and Iliana Medina. One in Swansea tinyurl.com/4thtbph6 deadline Jan 12th @crocus-dla.bsky.social The other in Melbourne - deadline Jan 1st Please share among potential students!

This is the Sunburst Candy Spider from Thailand. Not AI (sucks to have to declare this). Very real and had been on my wish list for a long time. The taxonomic placement is unclear, so we are leaving it at Cyrtarachninae.

I taught (and co-taught) a course on human population genetics from 2000-2024. Having retired, I'm now making all the course materials public: github.com/alanrogers/p... #popgen #evbio

Hello everyone! One of my colleagues and probably one of the best supervisors I've met, Dr. Iliana Medina, is advertising a PhD position involving lots of bugs and many different colours! More info in the image below, do share this widely!!

PhD opportunity in Melbourne, Australia, working in ecology and evolution of coloration with Iliana Medina (not on Bluesky). I can't recommend enough working with Iliana and living in that great city. Happy to chat if someone wants more details.

We are hiring in Evolutionary Biology — apply to join our department!

Been looking for a fresh specimen of Leucauge sarawakensis for a long time! Each time we found one, someone walked into its web. Hence, the ex situ shots.

We're excited to be recruiting an NIH funded postdoc to work in the Coop lab at UC Davis. We're specifically interested in candidates who are want to work at the intersection of human genetics, GWAS, and population genetics modeling. Please RT

NSF unexpectedly changed (at the last minute) who is eligible to apply for the Grad Research Fellowship, dropping 2nd year students. We started a petition to reverse this unfair change, Sign here: laurenkuehne.github.io/grfpChanges/ and please spread the word!!!!

Today my @nytimes.com colleagues and I are launching a new series called Lost Science. We interview US scientists who can no longer discover something new about our world, thanks to this year‘s cuts. Here is my first interview with a scientist who studied bees and fires. Gift link: nyti.ms/3IWXbiE

Meet new Stengl-Wyer Scholar, Fabian Salgado-Roa! He studies phenotypic and genetic diversity change at multiple geographical scales, using arthropods as a model system. Learn more about him at our new blog post. biodiversity.utexas.edu/news/feature... #biology #ecology #science #entomology

And look at this graphic abstract….. 😱🤯

Most "tarantula-like" (Mygalomorph) spiders can't use silk to balloon around, unlike "typical" (Araneomorph) spiders. BUT. Ummidia trapdoor spiders can! (still only as babies, same as all spiders.) That's why theyre so widespread around the world compared to their relatives! #Arachtober 🧪🌿🕷️

It was a pleasure to be involved in this!

Congratulations to Fabian Salgado-Roa, winner of the Medalla Humbold-Caldas Best Publication in Biogeography! His paper is titled "The Andes as a semi-permeable geographical barrier: Genetic connectivity between structured populations in a widespread spider." tinyurl.com/2pmcem2c

Awesome faculty position alert! Tenure-track assistant professor position in Evolutionary Biology, with a focus on organismal responses to environmental change. Please help spread the word! apply.interfolio.com/173889

Still possible to apply to this #post-doc position at CESAB #Montpellier. Application closing date: September 15th 2025 (12:00 PM CET) How taking intraspecific diversity and evolutionary processes into account in translocation-based programs. Please share widely #PopGen #NbS #Biodiversity

Applications for the 2026 Stengl-Wyer Scholars Program are open! The program provides up to 3 years of support for talented postdoctoral researchers in the broad area of the diversity of life and/or organisms in their natural environments. Learn more here: utexas.infoready4.com/CompetitionS...

Introducing the 2025 Stengl-Wyer Scholars, Fellows, and Grant Awardees! Another talented group we are excited to have! Learn about their fascinating research in our first blog posting of the fall semester. biodiversity.utexas.edu/news/feature...

At the same time, we made thousands of synonymous mutations in endogenous yeast genes and measured their growth. We used careful statistics and controls. Only 3%, 204 of 6874, had a fitness effect! This goes against a controversial recent result that most synonymous mutations had fitness effects.

Following funnel-web spiders — amazing work by Caitlin Creak: www.sciencedirect.com/science/arti... Study initially by @braxtonjones.bsky.social, Danilo Harms and I (funded by NatGeo and AusGeo), taken up by Caitlin with Russell Bonduriansky and Mike Kasumovic. Congrats all, especially Caitlin! :)

I'm happy to share with you that in a couple of weeks I'll start as a Stengl-Wyer Scholar at the University of Texas at Austin. I'll join @becca-young.bsky.social's lab to study the ecology, genomics, and development of my favourite colourful spiders.

The 2025-26 Eco-Evo job list is out. Good luck to those applying! docs.google.com/spreadsheets...

I am going to lodge a prediction: the AI bubble is going to start to deflate in the next 18 months. Chatbots have edge case utility, but are not themselves transformative. Agents are as controllable as an alcoholic rabbit; not fit for serious work. Foundation models are no longer improving rapidly

the ad is up! applications due 7/15: evol.mcmaster.ca/brian/evoldi...

Goldenrod Crab Spiders (Misumena vatia) are sexually dimorphic in size & color. The spider here is one of a few iNat observations of the species that shows both variations of dimorphism! 📷 cryokinesis on iNaturalist 📍 Canada 🔗: www.inaturalist.org/observations... #ObservationOfTheDay

Why do imperfect mimics (such as many hoverflies) exist? We created 3D printed replicas of flies, wasps and our own custom intermediates and then "asked" various predators what they thought of our 3D stimuli. Read all about it here: www.nature.com/articles/s41...

Congratulations to lab member Gabi Alves Ferreira who lead us in this fun project! She modeled how range shifts of neotropical frogs with climate change will change phylogenetic diversity and endemism in the new communities. So great to see this published #ProudPI 💪🐸 www.nature.com/articles/s41...

🚨Report your NSF grant terminations! 🚨 We are starting to collect information on NSF grant terminations to create a shared resource as we have for NIH. The more information we collect, the more we can organize, advocate, and fight back! Please share widely! airtable.com/appGKlSVeXni...

We have a fully funded International 4-year position (combined Master of Research+PhD) to study visual navigation in jumping spiders. Project will be supervised by @pipilika.bsky.social, @mherberstein.bsky.social, @dinrao.bsky.social & Ximena Nelson. At Macquarie University, Sydney. Details below
