We monitored 74 (41 male, 33 female) radiocollared raccoons (Procyon lotor) from February 1990 to July 1992 on the Welder Wildlife Refuge, Texas, to relate male and female space use to each other and to the spatial distribution of water, a critical resource for raccoons. Female home ranges were spatially aggregated early in the study, when standing water occurred in only a few, widely separated patches on the study site, but were randomly distributed during seasons when water was more widely distributed. Adult females generally foraged and rested independently of other adults. Most adult males were arranged in spatial groups whose home ranges overlapped little with those of adjacent groups. These groups were usually composed of three to four individuals; Doncaster's (1990, J. theor. Biol., 143, 431-443) test for dynamic interaction and visual observations showed that group members tended to associate positively during resting and foraging activities in all seasons. Among raccoons, as among many other mammals, female spatial patterns are apparently determined primarily by resource distribution, whereas male patterns are influenced by the distribution of females.

1990年2月至1992年7月，我们在得克萨斯州的韦尔德野生动物保护区对74只（41只雄性、33只雌性）佩戴无线电项圈的浣熊（北美浣熊）进行了监测，以研究雄性和雌性的空间利用情况以及它们与水的空间分布之间的关系，水是浣熊的关键资源。在研究初期，雌性的家域在空间上是聚集的，当时研究区域内只有少数几个相距很远的积水区域，但在水分布更广泛的季节里，它们的家域是随机分布的。成年雌性通常独立于其他成年个体觅食和休息。大多数成年雄性形成空间群体，其家域与相邻群体的家域很少重叠。这些群体通常由三到四个个体组成；唐卡斯特（1990年，《理论生物学杂志》，143卷，431 - 443页）的动态相互作用测试和视觉观察表明，在所有季节的休息和觅食活动中，群体成员往往表现出积极的关联。在浣熊中，和许多其他哺乳动物一样，雌性的空间模式显然主要由资源分布决定，而雄性的模式则受雌性分布的影响。版权所有1998年动物行为研究协会。版权所有1998年动物行为研究协会。
