Environmental change and anthropogenic stressors increasingly affect the alpine ecosystem. One species, well-adapted to alpine ecosystems, is the Alpine marmot, which is known to be sensitive to both heat stress and human disturbance. In my study, we aim to analyse the effects of environmental and anthropogenic factors, as well as the spatial social structure, on the abundance and occupancy of Alpine marmots. We surveyed a marmot population, consisting of ~70 family groups, in the Bernese Alps of Switzerland. Our results provide insight into vulnerability of this species to increased environmental and anthropogenic disturbances.
