Screenshot of the first page of the PDF of the Review article, Transgenerational plasticity and climate change: phenotypic responses across ectothermic animals, by Anthony Gilbert and Daniel Warner. The publishing information states: © 2026. Published by The Company of Biologists | Journal of Experimental Biology (2026) 229, jeb250304. doi:10.1242/jeb.250304. The first sentence of the Abstract says, 'Using organismal-level data to predict population-level responses to climate change is a common, yet complicated challenge'.

In their Review, Gilbert & Warner discuss how warming due to climate change can have effects across multiple generations of ectotherms and highlight knowledge gaps which would benefit from future research

Has anyone used Cayman Chemical kits for faecal glucocorticoid metabolite assays? Validating this kit for lizard faeces and on the struggle bus with some strange results. Trying to figure out if we've messed up the prep steps or the calculations. Would really appreciate some input/advice!

New 2026 paper led by @patricepottier.bsky.social, @kruthsatz.bsky.social & I in @conphysjournal.bsky.social show studies on embryos make up <10% of conservation physiology studies, highlighting a major blind spot in predicting vulnerable life stages to climate change.

'Hidden' group of gut bacteria may be essential to good health Scientists have pinpointed a group of bacteria that consistently appear in high numbers in healthy people, suggesting that these could one day be targeted through diet or probiotics

My favorite part of this article, in addition to the interesting new research on beneficial microbes (of course! of course!), is the picture that makes the gut microvilli look like hot dogs at a rave.

If Epstein is Trending, Why Isn’t +1.7°C? The news cycle has become a hall of mirrors: Epstein, Trumpism, war, outrage, retribution. A thousand scandals designed to keep us anxious, tribal, and tired. We have to hold multiple truths at once: ...

"This is the hard truth I want to land: climate does not care what’s trending. It’s not interested in Jeffrey Epstein, Gaza, or Greenland. There is no algorithmic mercy. Physics is physics, and it is getting more abrupt."

I am looking for a PhD student to join my new Socio-Eco-Evo group, hosted in Katie Peichel's Evolutionary Ecology Division @ University of Bern. We're offering a fully funded 4-year position, studying social plasticity and behavioral adaptation among stickleback in Greenland. Please share around!

Our new paper! Led by @miaryras.bsky.social with @wolfgangwuster.bsky.social and others 🦎

Winters are warming faster than summers, which could affect hibernating ectotherms, but it turns out that wall lizards cope well with warm winters & mini winter heatwaves, although they suffer more DNA damage, so the effects of warm winters may be concealed

A friend of mine suggested a whole blanket 🙈 yea/nah? Haha

Winter mini-heatwaves do not harm hibernating wall lizards obviously Summer heatwaves keep catching the headlines. Wikipedia has an entire page dedicated to the topic. But Miary Raselimanana (Bangor University, UK) and colleagues from the UK, explain that winters are w...

This one means so much to me. Working far from home and away from my little human has been one of the hardest parts of this journey, but moments like this remind me why I keep going. Every sacrifice, every late night, every tear… slowly paying off.

Our study shows that although wall lizards seem resilient to short winter warm spells, constant winter warming may carry hidden costs, including potential DNA damage. This is something I hope we can keep exploring in other temperate species because there might be more to the story than we think.

When we think of climate change/global warming, we often picture summer heatwaves. But winter is also warming AND that comes with its own consequences.

Experimental winter warming increases activity with signs of potential DNA damage in common wall lizards Highlighted Article: Winter warming makes hibernating wall lizards more active, with signs of DNA damage after emergence, but no change in body condition, revealing subtle costs of milder winters.

Folks, the first paper of my PhD is now officially out! 🦎🔥 (👇🏼comments)

Very cool to see this "Research Highlight" of our recent @animalecology.bsky.social paper that tested the potential for social buffering of maternal glucocorticoids in a facultatively social lizard. Grateful for this feature by Lange & Aracena! besjournals.onlinelibrary.wiley.com/doi/epdf/10....

🎉 Exciting milestone … my first PhD paper has been accepted in the Journal of Experimental Biology! 🥳
Not all winter warming is equal: steady, mild winters increase activity and can cause molecular damage, but short, warm spells have little effect on wall lizards 🦎

A big week for our research group! The first paper from @miaryras.bsky.social's PhD thesis has been accepted. Looking forward to sharing some nice results about the effects of winter warming on wall lizard behaviour and physiology very soon. Well done Miary! 🤩

Big milestone for me - the 1st MacLeod Lab get-together! @miaryras.bsky.social & I have been a dynamic duo for 3 years but we are now joined by Charlotte (cosupervised w/ @asutto.bsky.social) & MRes students, Keya & Sacheus. Research is even more fun when you’re part of such a great team 🤩
