This story is absolutely wild. Did you know that avocados change sex over the course of a day? And that it's controlled by a single ancient balanced polymorphism? This is flat our crazy

Empseb is simply the best. If you're a PhD student of evolutionary biology, do go there!

Excited to share the first two publications from our PERSIST (Predicting Evolutionary Rescue of a Species in Space and Time) project. Thanks to NSF-DEB for supporting this work! (1/3)

Before flowers evolved with attractive colors and scents, what did plants use to attract insect pollinators? Heat may be one ancient strategy. Valencia-Montoya and colleagues report their study of cycads in Science. Journal link in first comment. 🧪🌍🌱🐝 phys.org/news/2025-12... #pollinators

Exciting!!

Most of the internet is down because of this one issue... this includes most academic journal websites! Plos, Nature journals and biorxiv still seem to be up... for now. Made the mistake of closing many of the tabs I had open... sigh

academic.oup.com/evlett/advan... So exciting to see a new method to model the evolution of G (and P) matrices on phylogenies. Another step in the direction of trying to bridge micro and macroevolution

📣CALL FOR PAPERS! Upcoming SPECIAL ISSUE: Evolution at species range edges Guest Edited by Shengman Liu, John Pannell and Sophie Karrenberg More information here: academic.oup.com/jeb/pages/ca...

Part one of my common garden experiment is out today in Nature E&E!! We compare how urban and rural environments affect selection on HCN production, local adaptation, and eco-evo dynamics in white clover doi.org/10.1038/s415...

Out “in print”!

Analysis of crop yields, farmer income and bird species abundances identifies multiple positive outcomes of a large-scale Indian government-incentivized agroecology initiative. 🧪 www.nature.com/articles/s41...

Cuts to science are happening everywhere, along with more and more austerity cuts. #SaveSwissResearch #SaveSwissTeaching

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/... ), we find the opposite: animals exchange genes more, and for longer, than plants

Changes to a leaf trait due to adaptive evolution and plasticity can rescue subalpine populations from the detrimental effects of climate change doi.org/10.1093/evle... Now in @evolletters.bsky.social by Diane R Campbell, @jellyturtle.bsky.social, and Justin Kipness Illustration by J. Francis

A bit late, but really happy to see my first PhD paper out! We studied trait-elevation relationships in multiple traits spanning growth, size (both above and belowground) and leaf economics to understand whether these align at within- and among-species scales. academic.oup.com/evlett/advan...

Pre-print now out on bioRxiv! If you saw my talk at #eseb and want more info, here it is:

With #eseb2025 coming to a close, it is time to start making plans for 2026. Interested in the interface of evolution 🧬 and ecology 🌳? Come to our #ExE conference hosted by @uniexecec.bsky.social in beautiful #Cornwall. Leave your email address at tinyurl.com/EvolxEcol to join our mailing list!

Impossibly long queue for the symposium on forecasting evolution in natural populations at #eseb2025 Needs a much bigger room! :)

G.G. Simpson is the most mentioned paleontologist at #eseb2025. These are 3 different talks from two separate sessions. But there are more! adaptive landscapes, adaptive radiations and horotely (rates) are in! So is the fossil record! @roszenil.bsky.social @ignacioq.bsky.social and others!

Great first day in Barcelona and super excited for #ESEB2025. If you would like to know about alpine plants and elevational range limits, come to my talk at S14: Evolution at species’ range margins on Monday at 2pm!

... and here's a second #ESEB2025 starter pack! go.bsky.app/DnUAnt5

*Job alert* Come work with us! We have a fully funded 4yr #PhD position in #alpine & #Arctic plant #ecology available in our group @unibas.ch. The project includes fieldwork & connects to other ongoing projects on species range shifts & microclimate. jobs.unibas.ch/offene-stell... Please repost! 🌐🧪

My first solo author paper is now available in early view at Methods in Ecology and Evolution! I develop a covariance reaction norm (CRN) model for estimating continuous, multivariate, and nonlinear environmental effects on G and P matrices. besjournals.onlinelibrary.wiley.com/doi/10.1111/...

Does genetic rescue disrupt local adaptation? An experimental test using thermally adapted Tribolium castaneum lines https://www.biorxiv.org/content/10.1101/2025.08.07.669094v1

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.

*ALERT! GLOBAL GENETIC DIVERSITY TREND RE-ANALYSIS* "Signals of consistent genetic diversity decline are not yet measurable in global meta-analysis" doi.org/10.1101/2025...

Some really interesting papers in the last few weeks: www.science.org/doi/10.1126/... - behavioural drive related to C4 plant consumption drove morphological change in hominins. really cool use of isotope data (1/n)

⭐Issue 6 of JEB is now online!⭐ This issue is headlined by a Target Review from @josselin-clo.bsky.social et al. on #matingsystems evolution, accompanied by several #invitedcommentaries expanding on this key discussion comparing concepts in plants and animals: academic.oup.com/jeb/issue/38/6

As Requested - A Starter Pack of PIs in Biology (or adjacent) fields who are recruiting POSTDOCS! Please don't hesitate to reach out if you wish to be added! go.bsky.app/4gbXXR3

My talk from this year's probgen is finally out. Where do linear mixed models and random effects come from? They emerge from *mutations* on Ancestral Recombination Graphs.

Are you a PI in a biology field looking for postdocs? Here is a Starter Pack of early career biologists currently seeking postdoctoral positions! (Also if you are searching for a postdoc, let me know if you want to be added!) go.bsky.app/8zZNEGV

So very excited for the magnum opus of my #PhD to finally be out in @pnas.org. 🎉🎉 We demosntrate that mutualistic co-mimicking tropical butterflies not only converge in light microhabitat but, as a consequence, have also converged in visual system morphology! 1/n😀 www.pnas.org/doi/abs/10.1...

Our latest paper is out: rdcu.be/ev6Ym — one of my favorite projects. It began about 8 years ago when Nobel laureate Torsten Wiesel asked me: what transcription factors regulate new genes? I had no idea then. Now we have some answers.

Very excited to share the first chapter of my PhD thesis out in @elife.bsky.social : doi.org/10.7554/eLif... We discovered how the gene "mirror" is necessary for specifying the “vannus”, a unique domain in the posterior part of butterfly wings. 🦋🦋 (1/6) #CRISPR #butterfly #genomics

Two cave beetles lost the same visual genes after independent cave colonization. Why? Genes with fewer roles in the body (low pleiotropy) were more likely to be lost. Gene loss may not be so random after all: Niida, Ashida and Koshikawa doi.org/10.1093/jeb/...

*Job alert* Within our recently funded collaborative project focusing on assisted migration of #mountain #plant species, we are looking for a #PhD candidate based at ETH Zürich. For further details and instructions, see the job ad: jobs.ethz.ch/job/view/JOP... Please repost! 🧪🏔️🌿

any recommendations on cloud options to store a few 100 gigs of data after you finish projects? I have a physical backup, but paranoid about losing it/disk failure. decent pricing/gb and security are important! looking for ~2TB for now #EvoSky 🧪

Another cool new paper showing that developmental constraints likely connect micro- and macroevolutionary divergence www.journals.uchicago.edu/doi/full/10....

A new paper in Nature Ecol & Evol by @rosafernandez.bsky.social et al. shows a #punctuated burst of genome evolution in #annelids as they transitioned from marine to land and freshwater habitats.

Just hours before the end of the early bird, registrations are rapidly going up. We had an overwhelming response to the abstract. call (>2000) and the possibility of reaching the capacity limit is not so unlikely. So better hurry up to secure your spot at #ESEB2025 eseb2025.com/registration/

maybe my favorite paper I've written, I have a synthesis out today early access in @asn-amnat.bsky.social today that attempts to answer a simple but slippery question: what is an elevational range? doi.org/10.1086/737130
