“…Biotic and abiotic environmental variables (snow, food resources, predators), internal factors (physiological state, sex, age) and population density may influence spatial movements of mountain-dwelling ungulates (e.g. for the north-eastern chamois: VON ELSNER-SCHACK 1985; for bighorn sheep Ovis canadensis: FESTA-BIANCHET 1988; for Alpine ibex Capra ibex: GRIGNOLIO et al 2004;for woodland caribou Rangifer tarandus: OOSENBRUG & THEBERGE 1980). In mountainous areas, weather parameters, ecological variables and behavioural cues are the main factors underlying habitat selection of herbivores and in determining their movements and survival (SHACKLETON & BUNNELL 1987).…”

“…Le precipitazioni nevose influenzano la dinamica di popolazione, la sopravvivenza invernale è infatti influenzata dalla quantità di neve caduta al suolo (Grøtan et al, 2008;Jacobson et al, 2004;Saether et al, 2007) e questa variabile sembra essere un fattore chiave in grado di limitare la crescita delle popolazioni. Per lo svernamento, è rilevante la disponibilità di versanti estesi esposti a sud e a sud-ovest e con pendenze medie (35-45°), dove la neve tende a sciogliersi più rapidamente (Grignolio et al, 2004). Le pareti rocciose e le praterie d'alta quota rappresentano habitat d'elezione per la specie, mentre le formazioni forestali chiuse sono raramente frequentate.…”

“…Since one-point location may not be representative of the environment in which the animals live and could be subject to bias due to sampling method, average altitude and northness were additionally assessed for the circular sampling area (CSA, i.e., surface around the sampling location) of each individual, as proposed by Ramp et al (2005). Size of CSA was derived using home-range sizes from studies conducted in similar habitats (Hardenberg et al 2000;Meile et al 2003;Boschi and Grignolio et al 2004;Baumann 2005;Nesti et al 2010). Estimates (in hectares) depend on the species (ibex 0 i, chamois 0 c), sex (female 0 f, male 0 m), and season (wintering 0 w, summering 0 s): i-f-w 0 30, i-f-s 0 250, i-m-w 0 125, i-m-s 0 450, c-f-w 0 70, c-f-s 0 500, c-mw 0 10, and c-m-s 0 50.…”
