抽象抽象。在多纳纳国家公园用目击和无线电追踪的方法对自由放养的埃及猫鼬Herpestes ichapapon的群体规模、空间行为和个体间接触进行了2年的研究。平均群体规模为1.7只(范围1~5只)。成年雄性和雌性一年四季都是单独和成对出现的。夏、秋、冬三季均可见家庭群居。女性家园范围(尽管不是其核心区域)重叠，空间组织的特点是与丰富的食物资源片断相关的分布不均。男性是领地，他们的核心区域与一个或多个女性的核心区域重叠。雄性和雌性在14%的地点集中在一起，在交配期间和交配期间以外的样本中都有一只雄性与雌性有接触。埃及猫鼬不能被认为是一种严格意义上的独居食肉动物，但环境压力(主要是食物特性)似乎阻止了大型稳定群体的形成。
Abstract Abstract. Group size, spatial behaviour and inter-individual contacts in free-ranging Egyptian mongooses, Herpestes ichneumon , were studied by sightings and radio-tracking for 2 years in Donana National Park. Mean group size was 1·7 individuals (range 1-5). Adult males and females were sighted alone and in pairs all year round. Family groups were exclusively sighted in summer, autumn and winter. Female home ranges (though not their core areas) overlapped, and spatial organization was characterized by an uneven distribution in relation to patches of abundant food resources. Males were territorial and their core areas overlapped with those of one or more females. Males and females were together in 14% of locations, and a male sampled both in and outside the mating period had contacts with females. The Egyptian mongoose cannot be considered a strictly solitary carnivore, but environmental pressures (mainly food characteristics) seem to prevent the formation of large stable groups.
