摘要

动物行为的空间模式可以提供对栖息地质量和资源分布的深入了解。了解动物如何、何时以及为什么使用某些区域对它们的保护和管理至关重要。我们调查了瑞士阿尔卑斯山野兔Lepus timidus颗粒的分布，并比较了春季和秋季的差异。使用了来自119个个体（70只雄性，49只雌性）的1515个颗粒位置。2014年至2019年采集颗粒；个体是使用一种已建立的、非侵入性的遗传技术来确定的。我们发现了颗粒从春季的低海拔向秋季的高海拔发生海拔变化的证据。三个核心活动区（2只雄性，1只雌性）的海拔变化以及秋季高原较高的野兔活动也支持了这种季节性模式。我们得出的结论是，每年从低海拔到高海拔的绿化“浪潮”，与饲料的可用性和质量相关，解释了这种转变。

Mountain hares Lepus timidus follow the green-up wave in the pursuit of high-quality food

Spatial patterns in animal behavior can provide insight into habitat quality and the distribution of resources. Understanding how, when, and why animals use certain areas is critical to their conservation and management. We investigated the distribution of pellets of mountain hares Lepus timidus in the Swiss Alps and compared differences between spring and autumn. 1515 pellet locations from 119 individuals (70 males, 49 females) were used. Pellets were collected from 2014 to 2019; individuals were determined using an established, non-invasive genetic technique. We found evidence of an altitudinal shift in the occurrence of pellets from lower elevations in spring to higher elevations in autumn. This seasonal pattern is also supported by altitudinal shifts of three individual core activity areas (2 males, 1 females) and by higher hare activities at the high plateau in autumn. We conclude that the annual ‘wave’ of greening from lower to higher elevations, which correlates with forage availability and quality, explains this shift.

期刊介绍： WILDLIFE BIOLOGY is a high-quality scientific forum directing concise and up-to-date information to scientists, administrators, wildlife managers and conservationists. The journal encourages and welcomes original papers, short communications and reviews written in English from throughout the world. The journal accepts theoretical, empirical, and practical articles of high standard from all areas of wildlife science with the primary task of creating the scientific basis for the enhancement of wildlife management practices. Our concept of ''wildlife'' mainly includes mammal and bird species, but studies on other species or phenomena relevant to wildlife management are also of great interest. We adopt a broad concept of wildlife management, including all structures and actions with the purpose of conservation, sustainable use, and/or control of wildlife and its habitats, in order to safeguard sustainable relationships between wildlife and other human interests.
