了解野生动物种群的社会组织和间隔模式是保护管理和应用科学的一个重要方面。本研究调查了居住在爱尔兰针叶林的松貂（Martes Martes）的空间生态学，这是该物种最大的栖息地资源。这是对爱尔兰针叶林中松貂间距模式的首次研究。在2008年3月至2009年3月期间，对7只松貂（5公2母）进行了现场诱捕和无线电追踪，时间为4至10个月。雄性（150.7公顷）的年平均家园范围估计值（95%固定粒数）通常大于雌性（90.2公顷）。尽管用于比较的个体样本量很小，但在家庭范围内存在相当大的季节间重叠（约85%），性间重叠（12.0%）或性内重叠（11.8%）较少。松貂的家庭范围在各个季节都是稳定的。核心范围的大小从10.6公顷到104.1公顷不等，雄性和雌性的平均百分比分别为22.9%和42.5%。在森林管理方面，需要进一步研究松貂占用可用空间的潜力以及非常小的核心范围对砍伐行为的脆弱性，以确定对个体和种群的影响。
Understanding the social organisation and spacing patterns of wildlife populations is an important aspect of conservation management and applied science. The present study investigated the spatial ecology of pine marten (Martes martes) inhabiting conifer forests in Ireland, the largest habitat resource available for the species. It represented the first study of pine marten spacing patterns in Irish conifer forests. Pine marten (n = 7; five males and two females) were live-trapped and radio-tracked for between 4 and 10 months from March 2008 to March 2009. Mean annual home-range estimates (95 % fixed kernel) for males (150.7 ha) were generally larger than those of females (90.2 ha). There was considerable inter-seasonal overlap in home ranges (approx 85 %) with less inter-sexual (12.0 %) or intra-sexual (11.8 %) overlap, although the sample size of individuals for comparison was small. Pine marten home ranges were stable from season to season. Core ranges varied in size from 10.6 to 104.1 ha, and as a mean percentage of home-range area were 22.9 and 42.5 % for males and females, respectively. In terms of forest management, potential under occupancy of available space by pine marten and vulnerability of very small core ranges to clear felling practices needs further research to determine any impacts on individuals and populations.
