摘要: 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 other anthropogenic modifications of availability affect ungulate distribution, especially at their range limits. Here, we used a combination historical (1997–2002) contemporary (2012–2015) Eurasian roe deer (Capreolus capreolus) relocation datasets that span changes snowpack characteristics two levels supplemental feeding to compare forecast probability space use the species’ altitudinal limit. Scarcer snow cover period interacted with augmented site distribution increase elevation limits, predict this trend will continue under change. Moreover, have shifted historically using sites primarily deep conditions contemporarily them wider as increased. Combined scarcer during December, January, April, reduced inter-annual variability patterns these months. These spatial responses climate- artificial resource-provisioning shifts importance changing factors shaping large herbivore and, consequently, ecosystem dynamics.
