And (2) neither their melanin- nor carotenoid-based coloration are reliable indicators of Bd infection, suggesting that links between coloration & pathogen presence are more context- and taxa-dependent than often assumed (3/3)

We studied the prevalence of a pathogenic 🍄 (Bd) in six populations of dyeing poison frogs (N = 239) in French Guiana 🇬🇫 and quantified the characteristics of both their melanin- & carotenoid-based coloration, and found that (1) there are huge differences in prevalence among populations (2/3)

New paper out in @behavecol.bsky.social!
Multiple studies show that sexually selected traits such as colours can reflect the presence of pathogens/parasites, but, can defensive coloration do the same? L. Schlippe Justicia, @carodittrich.bsky.social, O. Nokelainen & I tackled that question (1/3)

The story on chemical communication in #poisonfrogs doesn't stop with the sexy fingers! "Histological and Gene Expression Analyses of the Arm and Finger Macroglands of Two Hyloxalus Frogs" is the new paper by the super talented Diana Abondano (Link in comments)! Out now in MolEcol. #cienciacriolla🇨🇴

Wonderful week in Seville attending the Spanish Ethology and Evolutionary Ecology meeting. Great science, friendly people, and the opportunity to reconnect with long-time colleagues and meet new ones. Many thanks to the organisers & the SEEE for the invitation! ☀️🌴🐸

Really enjoyable talk by an urban ecology rockstar @macgregorfors.bsky.social on urban ecosystem integrity. Who would have thought that you can get so much excitement from studying cities!🏙️🌿

And.... it depends! We found a positive association between the strength of the warning signal and the strength of the chemical defences in moths who had been raised on a high-protein diet 🐛 Those moths were in general redder 🔴🔴🔴 and more repellent for avian predators 🐥☠️ (2/3)

So happy to see this out in @funecology.bsky.social! We (@mothprof.bsky.social @crisottocento.bsky.social @jmappes.bsky.social et al.) studied whether the wing coloration of female wood tiger moths is an honest indicator of the quality of their chemical defences (1/3) @klivvvienna.bsky.social

Having Sir David Attenborough narrate a story based on our findings on the dyeing poison frog was something that I never imagined, even in my wildest dreams. Now it’s happening, in the new BBC series “Parenthood” (Episode on Freshwater)! 🤩 www.youtube.com/watch?v=1Zih...

One of those bitter-sweet moments in academic life… @carodittrich.bsky.social has been fundamental for the achievements we’ve had as a group and we will miss her greatly, but I’m already looking forward to hearing about the exciting science she’ll be doing in this new phase! 🤩🐸 🟡⚫️🦎⚫️🟡 🧬👩🏻🔬🫶🏼
