Very happy to present our work at @eoufledglings.bsky.social. Thank you to the organisers for a great event and to @dornitholges.bsky.social for supporting me with a travel grant. Amazing experience 🦆 🦅 🦢🐦‍⬛🪿🦜

We've all heard the "rule" that evolution favors promiscuous males and choosy females. But not always! Researchers found that in black coucals (pic below, since I'd never heard of them!) females had steeper Bateman gradients than males i.e. a greater fitness gain for each additional mating partner🧪

Who benefits from mating with multiple partners? Darwin suspected that in some cases, it may be the females rather than the males. A new long-term study on African coucals shows: when males provide all parental care, females can have more offspring by competing for and mating with multiple partners.

New research provides evidence that mercury and PFAS can influence mitochondrial function in free-living seabirds, highlighting bioenergetics as a sensitive mechanistic link between pollution exposure and organismal health. 🔗 Press release: www.bi.mpg.de/news/2026-01-hau

Marine pollutants disrupt cellular energy production in seabirds

A new study showed that presence of mercury was linked to inefficient fuel use during energy production in wild birds’ cells, while certain per- and polyfluoroalkyl substances (PFAS) may prevent prote...

Excited to share our new paper! 🎉 we explored foraging behavior, contaminant exposure ( #Hg & #PFAS), and mitochondrial bioenergetics, revealing how #pollution can affect cellular energy in an apex marine predator @stefi-casagrande.bsky.social #mitochondria pubs.acs.org/doi/full/10....

Pollutant Exposure Shapes Mitochondrial Bioenergetics in a Wild Seabird

Laboratory studies show that mercury (Hg) and per- and polyfluoroalkyl substances (PFAS) can impair mitochondrial bioenergetics, which is a vital process for cellular energy production. However, their...
