Abstract

Vegetation and its modification by humans can shape wildlife habitat selection and movement. A better understanding of how wolves select and move through natural and human modified vegetative cover can be used to implement forest management that considers impacts on wolves and their prey. We analyzed fine-scale wolf habitat selection and movement in a coastal temperate rainforest (Prince of Wales Island, Alaska, USA) in relation to: (1) young (≤ 30 years) and old (> 30 years) logged areas, (2) continuous measures of vegetative cover (as estimated via LiDAR), and (3) distance to roads, using integrated step-selection analysis (iSSA). Wolves selected areas with less forest canopy and understory cover at the population level, although they switched to selecting understory when within logged forest stands. The continuous canopy and understory measures vary at a fine spatial scale and thus appear to better explain fine-scale wolf selection and movement than categorical landcover classes representing the age of logged stands. Wolf selection of young (≤ 30 years) and old (> 30 years) successional logged areas, and areas near roads, was mixed across individuals. All individual wolves avoided canopy cover, but varied in their selection of logged stands, understory, and roads. Similarly, there was variability in movement rate response across individual wolves, although at the population level wolves moved faster through old (> 30 years) logged areas and through areas with less understory vegetation. Open vegetation including that present recently after logging is selected by wolves, and facilitates wolf movement, but this effect may be ephemeral as vegetation undergoes succession.

沿海砍伐雨林中植被对狼精细尺度栖息地选择和移动速率的影响。
植被和人类对其的改造可以影响野生动物栖息地的选择和运动。更好地了解狼如何选择和穿越自然和人类改造的植被覆盖,可以用于实施森林管理,考虑对狼及其猎物的影响。我们分析了美国阿拉斯加州威尔士王子岛沿海温带雨林中狼的栖息地选择和运动,包括:(1)年轻(≤30年)和老(≤30年)砍伐面积,(2)植被覆盖的连续测量(通过激光雷达估计),以及(3)与道路的距离,使用综合阶梯选择分析(iSSA)。在种群水平上,狼会选择林冠和林下植被覆盖较少的地区,而在被砍伐的林分范围内,狼会转而选择林下植被。连续的林冠和林下测量在精细的空间尺度上变化,因此似乎比代表被砍伐林分年龄的分类土地覆盖等级更好地解释了精细尺度上狼的选择和运动。幼狼(≤30年)和老狼(≤30年)在连续采伐区和道路附近的选择在个体间是混杂的。所有个体狼都避开树冠覆盖,但在选择被砍伐的林分、林下植被和道路方面有所不同。同样,狼个体之间的移动速率响应也存在差异,尽管在种群水平上,狼在旧(bb0 - 30年)伐木区和林下植被较少的地区移动得更快。开放植被,包括伐木后最近出现的植被,会被狼选择,并促进狼的活动,但这种影响可能是短暂的,因为植被会经历演替。

期刊介绍: Oecologia publishes innovative ecological research of international interest. We seek reviews, advances in methodology, and original contributions, emphasizing the following areas: Population ecology, Plant-microbe-animal interactions, Ecosystem ecology, Community ecology, Global change ecology, Conservation ecology, Behavioral ecology and Physiological Ecology. In general, studies that are purely descriptive, mathematical, documentary, and/or natural history will not be considered.
