Abstract

Prey species such as red deer () select their habitats according to their requirements for landscape features and adapt this selection to the presence of predators and humans. We tested how networks of different types of protected areas-the Swiss National Park (SNP) without hunting but with additional regulations for humans, and smaller-scale hunting ban areas (all types together = HBAs)-influenced diurnal and nocturnal habitat selection in red deer compared with unprotected areas.Using integrated step selection functions, we compared habitat selection of 243 GPS-collared individuals from six study areas across the Central Alps during day and night, during the year and specifically during the short autumnal hunting season.During the day, red deer avoided habitats where encounters with humans were likely, i.e., they selected for denser tree cover, greater distances to trails, steeper slopes, and for most of the year, for higher elevation. Importantly, in summer and autumn, they selected HBAs. At night, they showed the opposite selection. This daily pattern was absent in the study area centred on the SNP, where habitat selection was less specific overall. During the main hunting season, they selected HBAs over areas without protection during both day and night, and concurrently, habitat selection was less specific inside compared with outside HBAs.HBAs allow red deer to select habitat largely independently of human impact. Accordingly, compensating habitat selection at night due to human disturbance during the daytime was observed in all study areas, except for the region centered on the SNP. Our results suggest that in human-dominated landscapes, networks of small-scale HBAs can support more natural habitat selection of the animals, especially when providing additional regulations to humans.

摘要

马鹿()等猎物物种会根据自身对景观特征的需求来选择栖息地,并根据捕食者和人类的存在情况调整这种选择。我们测试了不同类型的保护区网络——禁止狩猎但对人类有额外规定的瑞士国家公园(SNP),以及规模较小的狩猎禁区(所有类型总计=HBA)——与未受保护地区相比,对马鹿昼夜栖息地选择的影响。利用综合步长选择函数,我们比较了来自阿尔卑斯山中部六个研究区域的243只佩戴GPS项圈个体在白天和夜晚、全年尤其是秋季短狩猎季节的栖息地选择。白天,马鹿避开了可能遇到人类的栖息地,即它们选择了树木更茂密的覆盖区域、离小径更远的距离、更陡峭的斜坡,并且在一年中的大部分时间里选择了更高的海拔。重要的是,在夏季和秋季,它们选择了HBA。夜间,它们的选择则相反。以SNP为中心的研究区域没有这种每日模式,该区域的栖息地选择总体上不那么具体。在主要狩猎季节,它们在白天和夜晚都选择HBA而不是未受保护的区域,同时,与HBA外部相比,HBA内部的栖息地选择不那么具体。HBA使马鹿能够在很大程度上独立于人类影响来选择栖息地。因此,除了以SNP为中心区域外,在所有研究区域都观察到了白天因人类干扰而在夜间进行的补偿性栖息地选择。我们的结果表明,在人类主导的景观中,小规模HBA网络可以支持动物进行更自然的栖息地选择,尤其是在对人类提供额外规定的情况下。
