I did it! Accidental aRt!

I am hiring a PhD student to join our group in Lund, Sweden working on an ERC-funded project to untangle color and polarization vision in some amazing crustaceans – minute water fleas and pugnacious mantis shrimp! Please forward this to promising students. Apply here: lu.varbi.com/en/what:job/...

The state of natural history institutions across Europe reflects decades of neglect and lack of vision from administrators, present and past

We often assume that reflectance is “spectrally well‑behaved.” If an animal is bright or dark in the (human) visible, surely the rest of the spectrum just… follows along? onlinelibrary.wiley.com/doi/10.1002/...

New preprint🚨happy to share work from my first PhD chapter, evaluating the ways in which we can integrate ancestral state estimations into disparity workflows, completed alongside @tguillerme.bsky.social , Gavin Thomas & @nhcooper123.bsky.social www.biorxiv.org/content/10.6... 🧪

Roll up, roll up! Looking for a postdoc? Want somewhere that's academia adjacent? Interested in seabirds, plastics, and conservation? Come work with me and @adriftlab.bsky.social! If you want to help develop an application, get in touch! #ornithology #seabirds #PhDjobs #PostdocJobs

Want to switch countries for a postdoc? Specifically, are you European, or are you non-European wanting to come to Europe? Now's the time to reach out to potential host labs! (It's very normal to cold-email a PI about potentially hosting -- don't be shy!)

Hi all. I am very excited that after 6 years I finally got my phylogenetic comparative methods book and online exercises online. Feel free to use and share. The book is here: nhcooper123.github.io/pcm-primer/. Note that it is not finished, we had to abandon it before the sunk costs fallacy broke us

I'm not comparing myself to Darwin "But I am very poorly today & very stupid & hate everybody & everything."

📢🦋 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/...

Every year again, this blows my mind. At the same a gentle reminder that one upon a time there were over a BILLION passenger pigeons alone. What we are seeing now is probably just a fraction of what we had before 😱

In 2017, we discovered the whereabouts of the last known male #greatauk 👉 tinyurl.com/3nc8s74x Now we’ve confirmed where the last female resides… Spoiler: she’s at @cincymuseum.bsky.social! Read the full story here 👉 academic.oup.com/zoolinnean/a...

Funded PhD position available 🎉 Come and work with me in Helsinki to uncover the pathways producing colourful tiger moth wings. Lots of options for genomics, CRISPR, fieldwork, behaviour experiments… Email with questions! jobs.helsinki.fi/job/Helsinki...

Super happy to share the first chapter of my PhD, published in the Journal of the Royal Society Interface ✨🐀 royalsocietypublishing.org/doi/10.1098/... Iridescence in mammals is not as rare as we thought, but it’s all created in the same way!

Hey you. Wanna apply for a fellowship on collections? the AHRC Early career fellowships in cultural & heritage institutions are open! The Natural History Museum priorities are below. If you wanna talk birds, hit me up. Collectors, colonialism, Canada, Australia & more www.ukri.org/opportunity/...

Mammal colours boring? Guess again (mostly a note to myself). Superstar Jess has been finding iridescence colours across mammals! royalsocietypublishing.org/doi/10.1098/...

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. rdcu.be/eD9Tt

My feather cell type paper is finally out! doi.org/10.1111/ede.... We’ve packed a ton of stuff into this paper but I’ll go through some highlights in this thread!

My talk at #eseb2025 is over, but do come and find me if you want to talk (bird) colour!

Great thread, great paper

New bird tree who dis. www.cell.com/current-biol...

New research in #ScienceAdvances shows that some songbirds have such bright-looking feathers by having a backdrop of black or white plumage underneath their bright feathers—an illusionary tactic of color also used by painters. Learn more in #ScienceAdviser: scim.ag/46ZaPeM

Is 2025 (red lines) a good butterfly year? Yes, on Dutch Butterfly Monitoring transects there are more butterflies than in 2023 and 2024. Numbers almost exactly equal 2022. But look at the 1990s. Compared to then it is a poor butterfly year. Shifting baselines!

Excited to advertise a shared PhD position at KU Leuven (Belgium) and Mondsee (Austria) with @markusmoest.bsky.social on the genetic basis, plasticity and evolution of melanization in Daphnia from alpine lakes. Apply here: www.kuleuven.be/personeel/jo...

Our new preprint @scottvedwards.bsky.social 🧬🐦 Long-read genomes show songbird germline-restricted chromosomes (GRCs; expelled from somatic cells) are 70 % repeats and packed with active LTR retroviruses. A hidden reservoir for TE-driven innovation/diversification! www.biorxiv.org/content/10.1...

Can macroevolutionary indices be used to inform contemporary extinction risk? We explore this question in an Ecology Letters review out today. Led by Sarah-Sophie Weil and Laure Gallien, it should be a useful resource for anyone using these approaches. onlinelibrary.wiley.com/doi/10.1111/...

Do I know someone who can help me with slides on plant diversity? I know nothing about plants, but my son is turning into Linnaeus, spending hours looking at flowers and classifying plant families (correctly). I would like to help him out (instead of the other way around 🤣).

A complete and dynamic tree of birds - out today in PNAS! Teamwork with @eliotmiller.bsky.social and others at @birdsoftheworld.bsky.social and Open Tree of Life to put together current relationships across all birds. www.pnas.org/doi/10.1073/...

⏰ DEADLINE IS TOMORROW (15 April) ⏰ Submit your abstract now! 🚨 #BOUasm25 | A day at the museum: collections-based ornithological research in a changing world 📅 18 Nov 2025 | Natural History Museum, London 🔗 bou.org.uk/event/a-d...#BOUasm25 #ornithology 🪶🧪

Our paper, on viewing condition and the evolution of plumage colour, is published! This was several years of work, building on our study of woodcock communication. Working with @sheardcat.bsky.social and John was a particular privilege. 🪶🧪#ornithology royalsocietypublishing.org/doi/10.1098/...

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)
