"Measurements of lizard carcasses found near colonies indicate that cats preferentially prey on larger individuals, explaining both their reduced abundance and their smaller body size" @airamrodriguez.bsky.social et al. Biol Lett. @royalsociety.org 🧪🌎🐊

Excited to share our results on genomic adaptation of the Arabian sand boa at #SMBE2026!

Have you ever thought of all what animals can do when predation is not a big issue? In this review 👉 doi.org/10.1016/bs.a... @maribelrm.bsky.social @juancarvajalcastro.bsky.social and I show how aposematism can be viewed as an “umbrella trait” influencing multiple aspects of its bearers' lives🔴🟡⚫

New PLOS Biology paper arising from a collaboration between us at the Sanger/U Cambridge and the U York and Sheffield, and many more collaborators across the Americas and Europe. Regulatory changes in the same genes (optix, ivory) led to the same colour patterns in mimetic butterflies and moths.

Check out our new paper where we sequenced a reference genome and did some comparative genomics for Tarentola mauritanica, really happy to work with a species that I can find in my terrace! 🦎🧬

Two new Science studies on lizard coloration reveal how a delicate interplay of genetics, environment, and social dynamics can either preserve or erase polymorphic diversity in species. 📄: https://scim.ag/4srYKHi 📄: https://scim.ag/4qCcsWn

Interactions similar to rock-paper-scissors help maintain color diversity in some lizard species, but the introduction of a dominant new phenotype can disrupt this balance and lead to color loss. doi.org/hbhxh4

How does development shape skull evolution? In lizards, neural crest–derived skull bones drive rapid sexually selected shape change within species but show long-term constraint, revealing developmental bias linking micro- and macroevolution. Image Credit: Wikimedia academic.oup.com/evlett/advan...

Just in time for the New Year we have a new preprint up that focuses on white cells, often used as ornaments in fish. www.biorxiv.org/content/10.6...

BIG day for warbler genomes, with work led by @kevinfpbennett.bsky.social! Whole genomes nearly *every species* of warbler. Warblers the most "Pokémon" of the bird world? Well, they're also trading their coloration genes like valuable collectors cards ... www.psu.edu/news/eberly-... 🦉🧪

I am so excited to share new work on a TE insertion that regulates iridescence in swordtails, led by fantastic grad student @nadiahaghani.bsky.social and with help from many coauthors!

🧪 New paper out! Growing up, wall lizards undergo a UV-visible “awkward phase” (who doesn’t?) that we can’t see—but they can. These ontogenetic color changes may mediate juvenile–adult interactions by delaying the onset of adult social signals. doi.org/10.1002/jez.... #colsci #lizard #ontogeny

📢🦋 Our paper ‘Global selection on insect antipredator coloration’ is out and featured on the cover of @science.org We ran a huge experiment to find out how ecological context favours camouflage and warning colouration as antipredator strategies. 1/6 www.science.org/doi/10.1126/...

Bird colouration varies a tremendous amount. But why? In a new paper, @j-dunning.net , John Endler, & I look at the relationship between plumage and viewing conditions in 2610 species of birds, finding strong, non-sexual effects (esp. on females). 📷Zak Pohlen (tanager), Darren Clark (thrush)

In the 1990s, >80% of Portuguese white storks were winter migrants. Thirty years on, a drastic shift in behavior means most individuals are now residents. Our new paper @animalecology.bsky.social combines census data, GPS tracking, and genomics to understand the loss of migratory behavior in birds:
