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...

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.

Please repost: 🚨Field assistant position 🐧

We offer a 14-months field assistant position through the French Polar Institute to work on king penguin ecophysiology and behavioral ecology.

Requirements: EU citizen < 30yo having experience with harsh fieldwork & wild bird/mammal handling/sampling.

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...

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

Blood mitochondrial function is linked to adult flight performance in a songbird. Whereas early-life thyroid hormones show no lasting effects on mitochondria, behavior, or performance.

Linosa, l’île refuge des puffins - Regarder le documentaire complet | ARTE À la rencontre des puffins de Scopoli, oiseaux pélagiques qui viennent chaque année nicher par milliers sur l’île volcanique de Linosa, au sud de la Sicile.

New documentary on our work with the enchanting #Scopoli’s #shearwater in #Linosa— a story of winds, wild journeys and also #mitochondria. 🐦🌊
So glad to have worked on this with #GiacomoDell’Omo and an amazing team #ValeriaVizioli #JürgenHansen #ArteTV #prospecttv
