The spatial patterns of Alpine chamois ( Rupicapra rupicapra rupicapra ) and their influence on population dynamics in the Swiss National Park

摘要: Summary From the birth season in spring until beginning of rut autumn, individually marked chamois (Rupicapra rupicapra rupicapra) were observed Swiss National Park. The focus was on spatial patterns and habitat characteristics three classes: females with young, without young though sexually mature, adult males. summer home ranges larger overlapped more than those young. In comparison, males had extremely small territories. Within study area, some sporadically never seen to impinge regularly females. It must be inferred that they belong other subpopulations. Habitat parameters provided little evidence for individual differences between members a given class: unlike generally avoided exposed places, whereas seemed favour them. There also distinct grouping patterns: shared their females, independently animal class belonged to, but stayed groups mostly solitary. is displayed behaviour allows best possible protection feeding conditions try build up fat reserves during summer. competition food overlapping social interactions males, apparently reduce survival rate chamois. Therefore, territorial likely play an essential role natural regulation population.
