Unveiling Diet Preferences and Their Nutritional Drivers Through Metabarcoding: The Case of Alpine Marmot (Marmota marmota L.) in High Altitude Grazed Pastures

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
The alpine marmot (Marmota marmota), a crucial component of alpine ecosystems, serves both as a key player in the food chain and as an ‘ecosystem engineer.’ Employing DNA metabarcoding of fecal samples, this study investigated the diet composition and foraging strategies of four alpine marmot colonies across diverse alpine pasture ecosystems throughout

Territorial birds of prey adjust their flight behaviour over the course of the breeding season depending on their breeding success

open access: yesJournal of Avian Biology, Volume 2026, Issue 2, March 2026.
Flight plays a central role in the life histories of birds but is extremely energy demanding. Reproduction is also associated with high energy demands. We might thus expect to see differences in movement behaviour between individuals that breed successfully, those that breed unsuccessfully, and those that do not breed, assuming that individuals adapt ...

Hunting, but not outdoor recreation, modulates behavioural tolerance to human disturbance in Alpine marmots Marmota marmota

open access: yesWildlife Biology, Volume 2026, Issue 2, March 2026.
Humans are often perceived as predators by free‐living animals, and thus, even non‐consumptive human activities such as outdoor recreation may trigger behavioural and physiological responses, often with negative consequences on individual fitness and population persistence.
