Climate change and anthropogenic food manipulation interact in shifting the distribution of a large herbivore at its altitudinal range limit

Abstract Ungulates in alpine ecosystems are constrained by winter harshness through resource limitation and direct mortality from weather extremes. However, little empirical evidence has definitively established how current climate change and other anthropogenic modifications of resource availabilit...
