FERAL 1.0 is out! Just to remind you: FERAL is an open-source toolkit for supervised animal behaviour segmentation directly from videos with no pose estimation needed. We made it much easier to install and run FERAL First, to install FERAL: pip install feral www.biorxiv.org/content/10.1... 🧵

In an article published today, we show that ancient feeding-related neuropeptides have been repurposed to control brood care in clonal raider ants. Photo: Bart Zijlstra, UNIL /1

I keep thinking back to this worm snake. Found under a rock in the back garden of an Air bnb during recent a fire ant collection trip to Athens, Georgia. They have extremely limited vision - check the rudimentary eyes - and a diet of 100% worm

Apply for a PhD position in the Pan lab @miyapan.bsky.social at MPI Biology 🇩🇪 to study the molecular mechanisms and evolution of sex determination in haplodiploid insects 🐜🐝.

Excited to share that I’m starting a research group at MPI for Biology Tübingen — and we’re recruiting PhD students! We are offering two fully funded PhD positions on sex determination and development in Hymenoptera 🐜🐝. Please share with prospective students who might be interested.

Excited about the prospect of being able to automatically annotate ant behaviour without going via pose estimation, which struggles in the situations we care most about

New article from the lab out today, in which we discuss how social behavior evolves at the molecular level. From parenting across the animal tree of life to caste systems in social insects, it’s all connected (and, therefore, slowly starts to make sense)…

Parental care, and more complex cooperative systems of care, have independently evolved in hundreds of animal lineages. In an article published today, we explore how these behaviors evolve 𝘢𝘵 𝘢 𝘮𝘰𝘭𝘦𝘤𝘶𝘭𝘢𝘳 𝘭𝘦𝘷𝘦𝘭l shorturl.at/g5OPw /1

What does mating look like when you only have a single shot at getting it right? Very excited to share our work on an almost-invisible female control, rapidly evolving mating recognition systems, and species that break the rules and take over the world. IN MOSQUITOES>

@AntCommunity 🐜 🐜 Chengyuan Liu found a Camponotus ant colony where all sexual larvae have red spots of various sizes, but worker larvae don’t. Any idea what this is?🤔 Video in the comment.

Playing hide-and-seek with saltmarsh sparrows at Plumb beach: This East coast endemic inhabits coastal salt marshes and is endangered by habitat loss

These two mourning geckos looked like they were mating outside my hotel room in Gamboa, Panama. They are both female. The mourning gecko is an all female species that engages in pseudo-copulation to stimulate egg laying. Not sure I’ve knowingly seen female-female mounting before.

A 𝘾𝙚𝙥𝙝𝙖𝙡𝙤𝙩𝙚𝙨 𝙖𝙩𝙧𝙖𝙩𝙪𝙨 worker with a strepsipteran parasite in its abdomen. Male strepsipterans look like normal insects but females are neotenic, retaining larval form throughout their lives. Females implant themselves into the abdomens of other insects & expose their anterior tip /1

(1) A moulting Cicada. (2) Moulding is a vulnerable moment - a moulting cicada getting eaten alive by big-headed ants. And (3) aduldhood also dangerous! A cicada in the mouth of a broad-billed motmot. Over the past few days in Panama.

Central Park is full of active Robin's nests at the moment. This one is at eye-level on the North side of the Pool @birdcpk.bsky.social

What a snake!

One of two wrentits rehydrating at a dripping pipe in Mission Trails, California. These are endemic to west coast scrubland, from Oregon south to Baja California, and are the only New World representative of the Parrotbills. They form lifelong pair bonds.
