Early view: we find that brown anole lizards are one of, if not the most, lead tolerant vertebrates known to science combining measures of field exposure, responses to lab dosing, performance assays and functional genomics. Led by PhD student Annelise Blanchette

Awesome new manakin work by @kevinfpbennett.bsky.social et al!

BCO2 controls collar pigmentation in Manacus manakins, and the pigmented-collar allele arose in one species, introgressed into a second, and kept on introgressin’ from the second species into a third 🧬🪶

Ah, bummer!! Hope to catch you at a meeting soon!

The quantity of fruit resources around male display courts significantly predicted male display rates, which in turn predicted rates of female visitation (a proxy for mating success).

Excited to share that my first dissertation chapter has been published in Biology Letters!

"Fruit resources shape sexual selection processes in a lek mating system"

Thanks Rafael!! Yeah, I couldn’t resist slipping that nugget in there as it’s something I’ve been thinking about a lot lately. Definitely partly Lewontin-inspired, and also links to your idea of lekking as an “evolutionary ratchet”! Will you be at AOS? Would love to discuss more!

Ooh, can’t wait to read it! Congrats!!

Yeah I hear you.. I suppose it’s only an issue from a modeling perspective if those life history traits (diet shift, female-only care, etc) aren’t already fixed in the pop prior to the start of runaway? (which, I have no idea if they are!)

Interesting! I’m wondering if allele(s) for increased maternal care would be necessary if changes in diet reduced the total parental care load. This is often suggested (but rarely tested) for lekking spp (switch to frugivory reduced foraging difficulty and “liberated” males from parental care)

Thanks!!

Fieldwork on Christmas Day => red and green color bands 🎄🪶

Sounds great, thanks!

A ~1.8m anesthetized bushmaster is laid out on a table, while a veterinarian/biologist (Dale DeNardo) makes an incision in the skin to implant a radio transmitter. Surgical tools are spread across the table and the head is being contained in a tube by a second biologist (Maria Elena Barragan).

Awesome to witness this bushmaster surgery at Reserva FCAT! Bushmasters are the longest vipers in the world, and researchers here are implanting radio transmitters to track the snakes’ movements, with goals of understanding their basic biology and reducing human-wildlife conflict in NW Ecuador.

Finally made it over to Bsky! I suppose it’s only fitting to kick things off with a manakin pic..
