了解野生动物的栖息地选择，特别是在人类主导的地区附近，对于确定人类与野生动物冲突的原因通常很重要。最近，随着日本定居点附近地区亚洲黑熊（Ursus thibetanus）数量的增加，人与熊的冲突也越来越多。由于这些冲突具有季节性，我们假设栖息地的特定季节限制可能会影响熊选择人类居住的地区。为了证实这一点，我们重点估计了潜在熊栖息地分布的季节差异。我们收集了日本阿尔卑斯山中部 1,023 平方公里范围内 14 只雌性熊和 15 只雄性熊的全球定位系统数据。我们利用资源选择函数来模拟特定季节的栖息地选择，并量化核心栖息地斑块的空间分布。与其他季节相比，夏季熊的栖息地仅限于人类统治的土地的狭窄边缘。对支持多种食物资源的较年轻森林、边缘和低地红松（Pinus densiflora）森林的选择表明，亚洲黑熊季节性依赖于早期演替阶段。在夏季，人与熊的冲突达到顶峰，熊避开种植园以及选择残余的小森林空地和低地森林，是影响熊靠近定居点的主要原因。我们建议野生动物管理者努力恢复茂密、成熟的种植园中的食物生产栖息地，以减少人类和熊之间的负面相互作用。 © 2017 野生动物协会。
Understanding habitat selection by wildlife, particularly in the vicinity of areas dominated by humans, is often important in identifying causes of human–wildlife conflict. With recent increases in the number of Asiatic black bears (Ursus thibetanus) in areas near settlements in Japan, there have been more human–bear conflicts. Because of the seasonal nature of these conflicts, we hypothesized that a season-specific restriction in habitat may influence bears to select human-settled areas. To confirm this, we focused on the estimate of seasonal differences in distributions of potential bear habitat. We collected global positioning system data from 14 female and 15 male bears in a 1,023-km2 range located in the central Alps of Japan. We employed resource selection functions to model season-specific habitat selection and quantified the spatial distribution of core habitat patches. Compared with other seasons, selected habitat of bears during summer was restricted to the narrow fringes of human-dominated lands. Selection for younger forests, edges, and lowland red pine (Pinus densiflora) forests supporting diverse food resources indicated that Asiatic black bears were seasonally dependent on early successional stages. In summer when human–bear conflicts peaked, bear avoidance of plantations and the selection for remnant small forest openings and lowland forest combined was the major cause affecting bear proximity to settlements. We recommend that wildlife managers work to restore food-producing habitat in dense, mature plantations to reduce negative interactions between humans and bears. © 2017 The Wildlife Society.
