thanks Julia 🫶

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.

If you are a current PRFB fellow, we have a slack where all of this and more is discussed.

Current fellows, please send me a message and I can add you.

Gut microbiome–diet interactions in wild birds Birds show global declines, and understanding the relationship between avian diet and fitness can both answer basic questions in physiological ecology and inform conservation efforts. Diet-induced ch...

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

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!)

Scott Taylor, on behalf of @jjinsing.bsky.social, tells the story of a potential instance of caterpillar mimicry in the White-necked Jacobin. The fuzzy baby hummingbird uses the unusually wiggles in the nest, mimicking local caterpillars & potentially helping to avoid some predation! #AOS25

I am opening scientific illustration commissions! Below are some examples of my work. Please contact me via bfitzwater@crimson.ua.edu if you are interested!

Do birds tune their songs to their hearing?

Is there tight coevolution between avian vocal signals and hearing-or do signallers and perceivers evolve more loosely?

It turns out perfect tuning is not required...

🧵Open submissions call! I recently took on a new position as Associate Editor of Creative Nonfiction at ISLE: Interdisciplinary Studies in Literature and Environment. If you have work that intersects people+nature in some significant way, I want to see it! Read on for submissions criteria...

Stand up for science. Stand up as if our lives and our economy depend on it. Because, actually, they do. #standupforscience

We share your excitement @jacanamama.bsky.social 🙌thanks for spreading the word & thanks for being part of SICB Portland.

Also! Want to be a part of this broader community, but don't know if your presentation fits the theme? Maybe you'd like to submit a paper to the associated ICB special issue?

Please get in touch! We are Karen Warkentin, @aramaticasper.bsky.social, and me :)

👀 I'm stoked to see what your talk is about!!

I'm SOOOO EXCITED for this Sex(es) Across Origins Symposium at #SICB2026!!!! I just submitted an abstract for the complementary session (on bird plumage and social selection with @gamaevo.bsky.social), and I hope you consider applying, too! @sicb.bsky.social @sicbjournals.bsky.social

A new time tree of birds reveals the interplay between dispersal, geographic range size, and diversification Flight may affect the dispersal and evolution of birds. Using a new evolutionary tree, Claramunt et al. find that efficient fliers have broader geographic ranges, and speciation reduces range size, bu...

Not to state the obvious, but some birds fly better than others. The ones that are awesome at flying -- this means they can get around obstacles, right? Expand their ranges as needed? Maybe be a little less vulnerable to extinction?

Turns out it's SUPER complicated.

Please get in touch! We are Karen Warkentin, @aramaticasper.bsky.social, and me :)

We'll be covering a broad range of topics, from organisms with non-canonical sexes and sexual systems, to evolutionary & developmental origins, to education research on how to teach about sex-related topics!

In short, if you *think* you might fit in, you probably do. Not sure? send a message!
