From our @hfspo.bsky.social project, where we have been trying to test out new methods and ideas!

NEW METHODS ARTICLE: Phylogenetic GLMMs open doors to study evolution of discrete traits. We show how binary models extend to ordinal & nominal traits, using bird data, and provide tutorials to make these methods accessible to evolutionary biologists: doi.org/10.1093/jeb/... Mizuno et al.

🚨RA/PhD position available in evolutionary neurobiology 🚨 Working on a deep dive into circuit changes during mushroom body expansion in Heliconius butterflies @camzoology.bsky.social - employment benefits - 4 years funding - 1000% fun Deadline: 14/1/2026 Details: www.cam.ac.uk/jobs/researc...

Coffee prices are up 21%. Ground beef prices up 13%. Big reason why? Trump’s chaotic tariffs on Brazil. I voted to repeal these tariffs along with every Democrat and a few Republicans, and it PASSED the Senate. All eyes now on House Republicans who are still on vacation.

Amazing eyes of the malachite butterfly (Siproeta steneles). Bosque da Barra, Rio de Janeiro.

Lots of interesting evolutionary nuggets in this study, and some we can’t exactly explain! A great combination of Yi Peng Toh’s patient neuroanatomical work and @fcicconardi.bsky.social’s bioinformagician skills, and another fun collaboration with @dickmerrill.bsky.social

New paper out! A nice collaboration. We explore how olfactory brain structures and receptors evolved across this remarkable group, Heliconiini butterflies.

Today´s Guardian has an article about our study on butterfly colors, where we compare butterfly colors in native forest to those in eucalyptus plantations. This is study is a partnership between labs from Denmark, Spain, and Brazil. www.theguardian.com/environment/...

Confused writing is usually a symptom of confused thinking. As we struggle to clarify writing, we clarify our thoughts. AI writing aids rob us of that struggle, leaving clean-looking text and thoughts still confused for lack of inspection. Writing is not just a product; it is a diagnostic tool.

Excellent initiative! I grew up thinking Greenland was huge and larger than the whole of South America. www.theguardian.com/world/2025/a...

Besides Trumpf deranged interference in my country, I am down to a new low. I have sent a manuscript for review to (so far) 11 potential reviewers (7 declined; 4 did not respond). I am now bothering a 12th potential reviewer... Any fellow assistant editors out there have had this happening before?

Trump is now imposing tariffs for political retribution.

With everything else going on, I'm not sure people realize that Trump's latest tariff on Brazil took things to a new (lower) level paulkrugman.substack.com/p/trumps-dic...

Fantastic place to work!

🚨Anyone want a job?🚨 We have two #postdocs up for grabs! 🧪 - cell developmental biology/#evodevo/#neuroevodevo - bioinformatics and molecular biology Both working on brain evolution in Heliconiini butterflies Details below! Please repost 🙏 1/n

Are you originally from a non-U.S. country interested in doing a postdoc in my lab? We study the evolution of butterfly vision and coloration. The Human Frontier Science Program postdoctoral fellowship Letter of Intent deadline is May 7. Please contact me if interested. www.hfsp.org/funding/hfsp...

Enjoy this great short (9 min) film on the work of Constanti Stefanescu, co-ordinator of the Catalan Butterfly Monitoring Scheme. Such schemes are not only important for the butterfly counts, but also as a social network bringing butterflies to the people. www.youtube.com/watch?v=d__p...

Interested in a PhD connecting sensory ecology and evolutionary genetics? Applications are now open for a project on the Speciation Genomics of Eye Size Variation in Heliconius Butterflies in our lab at LMU Munich: www.evol.bio.lmu.de/research/mer... Please repost!

First visit to a protected area that hosts the endangered butterfly Parides ascanius (Fluminense swallowtail). A small enclave in the heart of highly urbanized West Rio. Its host plant is the trilobed vine depicted here. The other vine is a passionflower plant. Tiger moth is a beautiful Poliopastea.

With some 20,000 species- four times the total diversity of mammals- ants have developed an enormous variety of forms. This is the soldier of Pheidole absurda, from Texas.

Greetings from a cloudy afternoon in Rio.

Kicking-up our Easter lab meeting with a chocolate bar extravaganza and a great talk by our newest post-doc Marilia Costa on land-use change and its impact on ant communities. Looking forward to a productive 3-year collaboration!

Happy to share my first major PhD work, where we show that Heliconiini caterpillars have developed more puncture resistant cuticle as a counter-adaptation against sharp Passiflora trichomes. However, we also show that the trichomes affect post ingestion, suggesting that the arms-race continues!

Sapsuckers are, without a doubt, my favorite birds! They drill these elaborate sap wells, which attract lots of insects... Here is a Red-naped Sapsucker hard at work, with some insects that came to her wells- Mourning Cloak, Red Admiral, Satyr Anglewing, plus Honey Bees and Bald-faced Hornets.

It's Thanksgiving in the US today! I thought it would be nice to do a sketch study of the Ocellated Turkey, a species of turkey found as far south as the Yucatán Peninsula, Mexico, and parts of Belize and Guatemala. Much more colorful than the Eastern US turkey. 🦃 #BirdArt #NatureArt #WildlifeArt

The tops of these mountains hold fossil sharks and fish that lived in subtropical streams 380 million years ago. Think about the disconnect between the past world inside the rocks and where they are today. Skelton Névé, Antarctica 2019 🧪 #paleontology #evolution #climate

Upper arms, forearms, even parts of our wrists originally arose in fish living in rivers, streams, and tidal environments hundreds of millions of years ago

Passando aqui para lembrar que a Alemanha, em 2020, por muito menos do que fizeram aqui em 2022, tomou a atitude correta. Bora?

Amazing!

Your reminder that many of the muscles, nerves and bones you use to hear and talk with correspond to gill structures in fish. 🧪 #evolution #paleontology
