Game night was going fine until the poison dart frog killed the vibe AND the players. Shared to me by @fprottis.bsky.social from our former teammate Oliver.

This grass moth is often invisible in still frames, but easy to see in motion. BehaveAI can use this motion to track tiny & camouflaged moving objects in complex scenes. Its semi-automated annotation workflow also means this moth-tracker took only an hour to make. Preprint: tinyurl.com/BehaveAI

1/9 New in @science.org www.science.org/doi/10.1126/science.ado8005 How does genetic architecture constrain evolutionary trajectories? To address this question, we inferred the genetic architecture of convergent plumage coloration and its evolutionary history in wheatears.

Bird species with specialized diets and migratory habits tend to show higher fear of novelty, a stable trait that may influence their adaptability to environmental change. doi.org/g96v62

What an amazing group of 🐛 @anurag-asclepias.bsky.social has written about his encounters with Euchaetes egle: how the caterpillars handle latex, & even caused him a nasty rash from their pupal hairs. Such small & formidable natural chemists! agrawal.eeb.cornell.edu/2018/11/24/c...

🍄 FLY AGARIC (Amanita muscaria) This fairy-tale fungus forms mycorrhizal partnerships with trees, trading nutrients for sugars underground. Its red & white cap signals potent compounds (ibotenic acid & muscimol) that can cause hallucinations and delirium. Strictly for admiring, not nibbling!

Calliteara pudibunda, the pale tussock moth caterpillar. Brilliant yellow tufts and an ultra-black stripe – a striking warning. When disturbed, it curls into a conker-like ball. Those hairs are likely irritating to the skin, a fine example of visual and chemical defence.

We are advertising for a postdoc with skills in psychophysiological measurement for a project on smell and emotions. Closing date is 30th October. Please spread the word. www.stir.ac.uk/about/work-a...

In a world bursting with colour, why go monochrome? I joined Tim Caro & Martin How on the BBC World Service’s Crowdscience to explore why some animals stand out in stark contrast. From 🦓🐼🐧 it turns out the answers aren’t always so black & white 😉 www.bbc.co.uk/sounds/play/...

🌍🦋 Across 6 continents, 21 sites & 15,000 paper moths, we joined a worldwide experiment led by @wlallen.bsky.social & Iliana Medina, showing how ecological context shapes the evolution of animal colouration. Proud to be part of this global team effort: doi.org/10.1126/scie...

📢🦋 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/...

A recipe from two eras for protection against bark beetles: Andrew O’Donnell et al. show in PNAS that some resin diterpenes are older than conifers themselves, while others developed independently—presumably to protect against bark beetles. www.ice.mpg.de/510162/PR_OD...

This magnificent ancient oak @kneppwildlandfdn.bsky.social is one of many around the U.K. that are heavy with acorns — a reminder of how oak trees quietly sustain whole worlds beneath their branches. Hundreds of species depend on them: birds, mammals, fungi, lichens, and countless insects.

New hope for the Wood White in Wales! 🎉 One of the rarest butterflies in the UK appears to be recolonising Wales decades after the last population died out. It has been recorded at four sites in Powys this summer - including a female laying eggs. 📷: Bob Eade
