🧪 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

New paper @biolinvasions.bsky.social led by Sarah-Sophie Weil.

Can macroevolution inform contemporary invasion potential?

We outline the assumptions of this approach, assess support, then test if dispersal ability can proxy for naturalisation success in several tetrapod groups.

What a week for our SHARKSense project - wrapped up our first field work in Costa Rica and Friday I'll share some colorful insights on sharks at UCR. Pura vida 🦈 @biovitenskap.bsky.social

Developed from the #WCH10 symposium, we provide a guide for researchers & managers on current advances for assessing the vulnerability of reptiles 🐍 & amphibians 🐸 to water stress | doi.org/10.1093/conp... | Published in @conphysjournal.bsky.social

🧪 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

Preprint alert: "Mating signal energy gradient mediates gene flow in the early stage of avian speciation". We studied 109 pairs of hybridizing bird species & unveiled some hidden roles of their magical mating rituals.

And here's the blog that outlines the 5-year journey and insights behind our latest article communities.springernature.com/posts/steppi...

8/ Read the full article here 👉 www.nature.com/articles/s41...

7/ Thanks to the support of our institutions, funding agencies, and journal @biologylu.bsky.social @naturecomms.bsky.social

6/ Shout out to the superb team @michaelnicolai.bsky.social et al.

5/ This study emphasizes the complexity of color evolution, driven by multiple ecological and evolutionary pressures across species. Leveraging our database and understanding these dynamics can help predict how species may respond to future climate shifts

4/ But it gets more interesting: we found that color brightness evolution rates are shaped not only by current environments, but also likely by major climate shifts

3/ Squamates in open habitats tend to be brighter, suggesting that thermoregulation has an important role in shaping color brightness variation

2/ Our research shows that the influence of habitat openness is stronger than other factors like body size or other eco-environmental variables

🧵 1/ New study on squamate color evolution hits the press: we show that brightness variation in lizards & snakes is strongly linked to habitat openness 🌞 This reveals how ecological pressures drive color evolution in one of the most diverse groups of tetrapods www.nature.com/articles/s41...

We are very excited to share our new paper in Science! We show that a diverse group of Jurassic and Cretaceous mammals all had darkly-colored fur.

Well how did we do this? Let' start at the beginning!

How vulnerable are #amphibians to extreme heat? 🐸🌡️

Our paper in @nature.com shows that many amphibians are already overheating, and many more species will be impacted by climate warming globally.

Color evolution wasn’t inevitable - was it? In a recent article for @uk.theconversation.com, I explore some of the latest research on how animals and plants co-evolved to bring vibrant colors into our world
theconversation.com/why-did-life...

This is a major collaborative effort, involving 8 countries across 3 continents 🌎🌍🌏

Hi Bluesky! Excited to share a new project I’ve just kicked off: SHARKSense 🦈. We’re exploring how heavy metals impact melanin deposition and evolution in sharks. Can the darkness of shark integument indicate pollution? 🤔 This is just the beginning - stay tuned for shark color tales from the field 🌊
