I made a map of 3.4 million Bluesky users - see if you can find yourself! bluesky-map.theo.io I've seen some similar projects, but IMO this seems to better capture some of the fine-grained detail

🪿 Early-life stasis in partial seasonal migration is underpinned by among-cohort variation in migratory plasticity and selective disappearance 📖 Read the full paper here ➡️ buff.ly/9mleVea

Some really cool work on what makes (and breaks) an evolutionary individual!

How do temperature regimes shape trait diversity in communities? Does variability promote more specialists or more generalists? Our new Nature Communications paper tackles this with eco-evo simulations + 653 moth species across latitudinal and elevational gradients. www.nature.com/articles/s41...

Please join us for a @smtpb.bsky.social panel discussion about publishing theory in biology w/ @joshuasweitz.bsky.social (Co-Chief Editor of J Theor Biol), Mark Lewis (Advising Editor for J Math Biol & Bull Math Biol), and me (Theor Pop Biol) 13 Feb 2026 9:00AM–10:00AM PST smtpb.org/event-6520871

Today's board work (ft. truly incredible Hagoromo chalk). Anybody wanna guess what @kokkonut.bsky.social and I are working on? ;) (hint: it's a topic in population biology that many non-scientists spend a lot of time worrying about).

Expressions of interest: Director at MPI EvolBio (f/m/d) — We invite expressions of interest from distinguished scientists in evolutionary biology with a bold, long-term research vision that complements our Institute. More information: www.evolbio.mpg.de/3856225/Dire...

The greatest addition to my CV so far: I am now officially part of The Luxuriant Flowing Hair Club for Scientists improbable.com/2026/01/14/s...

Me: surely at least the statistics literature has its house in order. The stats literature:

👇 Exciting post-doc with a fantastic PI!

I'll admit I don't usually worry about whether my fitness functions are Lipschitz or merely α-Hölder, but a really nice idea here (I've only skimmed it) is that extreme ruggedness ⟹ loss of Lipschitz continuity ⟹ diff. eq. solns can be non-unique because no more Picard-Lindelöf ⟹ contingency Cool!

Not for academics it isn’t. You learn by reading and by following citation chains and talking to other people in the field. Letting the AI do the summary is abdicating your job.

excited to announce v2 of my stochastic eco-evo framework is up ! main text now clarifies links w prev werk and points to an emp test of gen corrs result . supp greatly expanded to include worked derivations and further explanation of mathematical foundations !! hope u enjoi ;) tinyurl.com/stecoevo

Before 2025 closes out, I wanted to make a thread on my proudest recent paper! (Ok, it's from 2024, but I haven't done a bluesky thread on it before). Allen et al. (2024) "Nonlinear social evolution and the emergence of collective action", PNAS Nexus academic.oup.com/pnasnexus/ar...

A new (and improved) version of the fantastic BES’s reproducible code guide is now live. Seriously amazing resource for those wanting to produce code that enables reproducible research. Featuring some SORTEE members and also code review!! @sortee.bsky.social

Woohoo! Congratulations, @kokkonut.bsky.social !! 🎉🎉

Looking forward to the Modern Coexistence Theory workshop tomorrow. Please repost :)

Hi everyone! I'm co-organizing this retreat/workshop June 15-19 for those looking to get started in mathematical/computational modeling of biological processes. Location is a beautiful farm in NC. Please share with students and others who want to build modeling skills. Interdisciplinarity welcome!

When the journal Theoretical Population Biology was founded in 1970, it was reviewed in Nature by J.R.G. Turner.

Now free to read in Genetics (@genetics-gsa.bsky.social): "Preventing evolutionary rescue in cancer using two-strike therapy" #mathonco study by @srishtipatil.bsky.social, @armaanahmed.bsky.social, Yannick Viossat and me, determining the optimal time to switch treatments. doi.org/10.1093/gene...

📢❗🚨Reminder: POSTDOC in THEORETICAL ECOLOGY. Great opportunity to develop theoretical models on the ecology of food systems, exploring key aspects such as biodiversity, spatial heterogeneity, pollination, and stability. Close collaboration with researchers from multiple disciplines & countries

A while ago @caritalindstedt.bsky.social asked me “would you puke to save the group?” Well not me personally, there's real science about the evolution of cooperation here. With the help of talented student @abhay-gupta.bsky.social, we now have answers! royalsocietypublishing.org/doi/epdf/10....

Why is altruism more common in nature than spite? This new paper gives a general mathematical explanation: the degree of negative assortment that can be achieved is constrained in a way that positive assortment is not, particularly in unbalanced populations. www.sciencedirect.com/science/arti...

i will be giving a talk on some recently published work on the 4th of December. Come by (zoom link below) if you want to think and learn about the evolution of mutual dependence and synchronised reproduction in endosymbioses!

Hot off the press! Our latest paper led by @fernpizza.bsky.social, understanding how plasmids evolve inside cells. These small, self-replicating DNA circles live inside bacteria and carry antibiotic resistance genes, but also compete with one another to replicate. 1/ www.science.org/doi/10.1126/...

Happy to share that our paper ‘a formal theory of group-level adaptation for obligate eusociality’ (with @andygardner.bsky.social) is now out in @jevbio.bsky.social advances. doi.org/10.1093/jeb/... #OpenAccess #Eusociality #GroupAdaptation #FormalDarwinism

This is a reminder that @asn-amnat.bsky.social publishes abstracts in both English and your native language, using your native alphabet. You can see and read those online. Here is a screenshot of a great example. Love seeing this in my favorite journal.

Myself and Alastair Wilson wrote an updated version of our 2016 primer to quantitative genetics in the wild: www.sciencedirect.com/science/arti.... Happy to share a copy if interested. It is also on research gate

As a longtime RStudio and ggplot user, it is really disappointing to see the (still?) head of Posit and author of R For Data Science using LLMs to create translations of package vignettes, instead of hiring a professional

Interested in resource competition theory, mutualism, spatial patterns or temporal dynamics? I'll be giving a talk in the IITE online seminar series tomorrow summarizing our recent work on microbial cross-feeding that includes all these ingredients.

Analog machine that simulates solutions to the Schrödinger equation when you take long exposure pictures of parts of its motion 🤯

In the early days of quantum chemistry, before we had computers to calculate the shapes of electron orbitals, one man invented a mechanical machine that simulated their shapes. My latest column for @chemistryworld.com www.chemistryworld.com/opinion/the-...

What is sexual selection all about... definitionally and mathematically? A super talented PI, Jussi Lehtonen, is looking for a postdoc to work it all out! Deadline end of this month. ats.talentadore.com/apply/postdo...

4) “the complexity of biological phenomena is an argument for the use of mathematical methods rather than against it. In the case of a simple phenomenon we may hope to understand it without the use of mathematics, by simple inspection. But in a complex case we are left hopeless without mathematics.”

Looking forward to this! A non-Elsevier alternative to Theoretical Population Biology / Journal of Theoretical Biology
