On this side of the fence: Functional responses to linear landscape features shape the home range of large herbivores

1. Understanding the consequences of global change for animal movement is a major issue for conservation and management. In particular, habitat fragmentation generates increased densities of linear landscape features that can impede movements.

2. While the influence of these features on animal movements has been intensively investigated, they may also play a key role at broader spatial scales (e.g. the home range scale) as resources, cover from predators/humans, corridors/barriers, or landmarks. How space use respond to varying densities of linear features has been mostly overlooked in large herbivores, in contrast to studies done on predators. Focusing on large herbivores should provide additional insights to understand how animals solve the trade-off between energy acquisition and mortality risk.

3. Here, we investigated the role of anthropogenic (roads and tracks) and natural (ridges, valley bottoms and forest edges) linear features on home range features in five large herbivor...

1. 明晰全球变化对动物移动行为的影响，是保护与管理领域的核心议题之一。具体而言，生境破碎化（habitat fragmentation）会提升线性景观要素（linear landscape features）的分布密度，进而阻碍动物的移动过程。
2. 尽管学界已针对这类要素对动物移动的影响开展了大量深入研究，但它们在更大空间尺度（如家域（home range）尺度）中或可发挥关键作用：既可作为资源供给、躲避捕食者/人类的掩体，也可充当廊道、屏障或是地标。相较于针对捕食者的相关研究，大型草食动物（large herbivores）如何响应线性要素密度变化的空间利用策略，迄今仍未得到足够关注。聚焦大型草食动物的相关研究，可进一步助力我们理解动物如何在能量获取与死亡风险之间达成权衡取舍。
3. 本研究旨在探究人为（anthropogenic，涵盖道路与小径）与自然（涵盖山脊、谷底及林缘）线性景观要素对5种大型草食动物家域特征的影响……
