Heliconius erato demophoon sat on a pink, yellow and white lantana flower. The left side of the butterfly is white, while the right side is the usual black and red, but with some white clonal patches.

New preprint form me and the McMillan lab at STRI and Martin lab at GWU, digging into scale cell type specification and differentiation in Heliconius wings, with some insights on the lncRNA gene ivory.

I'm able to keep doing my work by focusing on inspiring leaders wherever I find them. Today I'm thinking about Sue Pierre & her astonishing work with the Critical Ecology Lab.

Please repost! We are looking for two field technicians to work on our deer mouse project in the Colorado Rockies this spring-fall. Learn about physiology, ecology, and evolution, all in one project! Not to mention that you get to be in the ⛰️. Reach out if you have any questions.

I often use @rossbrooks.co.uk articles in my teaching materials and have been waiting for a book for years! Excited to see this happening, congrats!!

Are you (or do you know someone) recently graduated from undergrad looking to beef up your skills and experience prior to starting grad school/career? Do you like social drama and parakeets? Come join my team! I'm looking for two people to start very soon!! tinyurl.com/59rf8jcy

Two - count ‘em - two #SICB2026 talks that I’m giving today, Tuesday, January 6. Come watch me pour the absolute last of my energy into telling stories about two rather unique birds and about how nature is really weird and wonderful.

Thanks Emily!!

@jjinsing.bsky.social , an organizer of the Sex Across Origins symposium at #SICB2026, talks about how we can think of sex beyond the binary. There are many traits beyond gametes that shape an individual’s ability to reproduce. By treating sexes as polymorphic, we can communicate more clearly.

I am currently at #SICB2026! I am in the Multimedia Panel tomorrow at 12:15, and will also be presenting my research on Tues. at 11:15, and mine and @taorminalepore.bsky.social's symposium, "Disabled and neurodivergent perception, community, and identity in the biosciences" is Wednesday!

Logo for the Sex Across Origins symposium. A round cell looks like it’s about to divide, with spindle fibers. In the middle there are two rainbow-colored phylogenies. Outside the cell, it says “Sexes Across Origins” on top, and “SICB 2026” on the bottom

It’s happening!!

#SICB2026 Tomorrow, from 8AM to 3:30PM come to C120/121/122 for ✨Sex Across Origins: Questioning animal-centric assumptions and developing integrative frameworks.✨

Also! 3 fantastic complimentary sessions Tuesday in B113, with a special focus on education in the morning.

We are delighted to announce our upcoming LGBTQ+ seminar given by Dr Ross Brooks who will be talking about his upcoming book, Darwin and the Queer Origins of Life! 2nd December @ 4pm in the Life and Mind Building, open to all members of Oxford university 🥳🏳️‍🌈🏳️‍⚧️

Thank you for the well wishes!

He Studied Why Some Female Birds Look Like Males

"The project that was terminated was on this hummingbird, the white-necked jacobin....I suspect that it has something to do with studying a species that doesn’t fit the binary." Researcher @jjinsing.bsky.social interviewed by @carlzimmer.com #birds #nature #science #fundscience #nonbinary 🧪

If anyone is interested in expanding my ongoing Paulinella projects and/or doing other work in algal genomics in my lab that doesn’t fully exist yet (but will exist at the time the funding for this starts), please reach out! I’d love to help develop a cool project with you!

How do light and noise pollution impact selection on sexual signals?

We tested mate attraction and bat predation on túngara frogs in the field.

DIJKSTRA LAB - Social behavior and physiology Welcome to the Dijkstra lab at Central Michigan University! We study how social competition and oxidative stress shape brain function, stress resilience, and evolutionary processes. Using African cichlid fish (our primary model for studying social behavior), we combine behavioral, physiological,

The Dijkstra lab at CMU seeks PhD students for Fall 2026, funded by an NSF award, focusing on aggression in cichlid fish. Apply to Dr. Dijkstra by Oct. 20. More info: https://sites.google.com/site/peterdijkstrausnl/home #phd

I am recruiting 1-2 graduate students (M.S. or Ph.D. track) to join my lab at @psychualberta.bsky.social in Fall 2026! Please share widely, and if you are interested in endocrinology, animal behavior, neuroscience, and/or seasonal biology, I would love to chat! 🐟🧠🧬🍂

Buscando estudiantes para empezar en agosto de 2026. Estudiamos la evolución de las señales químicas de los insectos con biología evolutiva, ecología química, biología molecular, y estudios de comportamiento. Más información aquí: tinyurl.com/mrxchwfm

Green butterfly sat on a flower.

I'm looking for PhD students to join the lab starting August 2026. We study the evolution of insect chemical signals so if you're interested in evolutionary biology, chemical ecology, molecular biology, behavior, or genetics, this could be a good fit for you! More info here: tinyurl.com/mrxchwfm

Thank you Suvi and everyone in the environmental physiology lab @uniofjyvaskyla.bsky.social!! So incredibly warm, friendly, and inspiring! Cheers!

Fig. 1 CO2 production for four species of dung beetle showing sexual and male dimorphism. (A) CO2 production for morphs of each species not accounting for beetle mass or activity. Boxplots correspond to the first and third quartiles, and whiskers extend to the most extreme data value within 1.5 times the interquartile range. Jittered points show data for individual beetles. (B) Expected CO2 production from beetles of a given morph with average mass for each species and average activity across species. Points show least squares means and 95% CIs around the means. Letter labels indicate significant differences.

OKAY, BUT... BIRDS

When we have so many painful and dangerous things to grapple with, it makes the joyful things that much more precious. Seek them out, save them, share them!

Here’s one I’m *really* excited about: www.okaybutbirds.com by the hilarious & charming @drscottataylor.bsky.social

@lannhiphung.bsky.social studies the link between genomic history and sexual selection in bowerbirds, an iconic example of sexual signaling through both behavioral and physical attributes. There are at least 36 genes under different levels of selection pressure in one or multiple clades! #AOS25

Skipping live-scicomming the next session because I’m in it! If you’re at #AOS25 come see me talk about a weird bird and it’s cool genome at 4:45 in Genomics 3 (Ballroom A). (Or email me any time!)
