Lizards and the colors we can’t see! 🦎✨ Juvenile Podarcis muralis undergo ontogenetic color changes that are invisible to humans but perceptible to conspecifics, likely functioning as social signals. #Herpetology onlinelibrary.wiley.com/doi/10.1002/...

It is out, it is out! Our study on neural crest cells and micro to macroevolution in lizard skull 🦎

High-energy particles streaming through space can damage DNA and increase cancer risk, but antioxidants, tardigrades and hibernation could help astronauts make the journey safely.

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...

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

🧪 Check this if you are interested in the convoluted evolution of lacertid colours. Yes, I know, we missed a unique opportunity opportunity to call the phenomenon "Chromatic Barrier of the Appennines", which totally sounds like a badass DnD spell. #evolution #colsci #lizard #sexualselection

Today I found out that the sex pheromones of Aplysia (a genus of extremely large sea slugs) are called: • Enticin 🌶️ • Attractin 👁️🫦👁️ • Temptin 🌺 • Seductin 🔥 And I find that wonderful. Please vote for your favorite. Credits to Trystam Wyatt's book on Pheromones and Animal Behavior. #ethology

🦎THREAD: We just published something wild in @asn-amnat.bsky.social - lizards missing entire limbs not only survive, but some appear to actually thrive in the wild?! Let me tell you about the "three-legged pirate" lizards 🏴‍☠️ [Paper: www.journals.uchicago.edu/doi/10.1086/... ] (1/n)

Round 4 of surveys for the Mt Lyell #salamander (Hydromantes platycephalus). We were able to sample 7 salamanders this time, including a juvenile! #herpetology #herps #amphibians

📢🦋 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/...

Many wall lizards briefly sport bright blue tails as predator decoys after hatching. Our new study shows their throats and bellies also change color, yet at wavelengths invisible to humans! Could other species, too, undergo such cryptic shifts? @uv.es @ucciuv.bsky.social tinyurl.com/4rjfmde9 🧪🦎

🧪 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

333 wolf packs in Spain, 12% increase from the previous census (>10y ago). Sadly, local governments are approving 20% culls (targeting adult mothers for extra damage, ofc). The official excuse: preventing food waste. I kid you not. #lobovivo #loboprotegido #wolf elpais.com/clima-y-medi...

Together with student Isabel van der Velden we started working our way through the collection. And YES we found microplastic... 😱 (This is now her first scientific publication! Congrats Isabel!! 🥳) Everyone can read it as the story is fully #openaccess ✅ www.sciencedirect.com/science/arti... 8/x

NEW PAPER, JUST OUT! 👀 Insects from the '70s and '80s were already collecting microplastic, decades before the term microplastic even existed. 🤯 A thread on the surprising history of this pollutant and the incredible insect larvae that helped us uncover it. 🐛 Let's dive in! 🧵👇 1/x

🧪 Is lizard iridescence really about predators or conspecifics seeing them from different angles? Unlikely. Just look at this female—curled up so her front looks brown and her back green. It’s probably a nice byproduct… or maybe the trick is the ever-shifting appearance itself? shorturl.at/jfjIw

🧪 These two lizards are the same individual, despite shimmering in different colours. This might have made you expel a puff of air through your nostrils while thinking a lowercase "lol" (or so I hope). It took us 4 years @jzoology.bsky.social zslpublications.onlinelibrary.wiley.com/doi/10.1111/...

The lizard in these two images is the same individual, despite shimmering in different colours. This might have made you expel a puff of air through your nostrils while thinking a lowercase "lol" (or so I hope). Well, you should know that it took us 4 years to do the math. @jzoology.bsky.social

@jeffsebo.bsky.social @birchlse.bsky.social and I put a lot of philosophy into our new Science Perspective on animal consciousness. Mill's analogical argument + inference to the best explanation + careful experiments = justification for consciousness in many animals. Where might it end?
