摘要

我们研究了日本北部入侵的果子狸（Paguma larvata）的摄食习惯和季节变化，以了解它们的摄食策略。在 2020 年至 2022 年期间，我们收集了 98 份果子狸的粪便样本并对其内容进行了分析。果子狸主要以水果（点框法为78%）和节肢动物（15%）为食；全年都吃水果，但在冬季节肢动物缺乏时，水果的摄食量会增加。除了身体和行为适应性之外，果子狸的摄食可塑性使其能够在温带地区的引进栖息地扩大分布。

Food habits of invasive masked palm civets (Paguma larvata) in northern Japan

We examined the feeding habits and seasonal changes in invasive masked palm civets (Paguma larvata) in northern Japan, to understand their feeding strategies. Between 2020 and 2022, we collected 98 fecal samples from masked palm civets and analyzed their content. The civets fed mainly on fruits (78 % in terms of the point-frame method) and arthropods (15 %); fruits were consumed throughout the year, but increased in winter when arthropods were not available. The feeding plasticity of masked palm civets, in addition to their physical and behavioral adaptations, enables them to expand their distribution in introduced habitats in temperate regions.

期刊介绍： Mammalia is an international, multidisciplinary, bimonthly journal devoted to the inventory, analysis and interpretation of mammalian diversity. It publishes original results on all aspects of the systematics and biology of mammals with a strong focus on ecology, including biodiversity analyses, distribution habitats, diet, predator-prey relationships, competition, community analyses and conservation of mammals. The journal also accepts submissions on sub-fossil or recently extinct mammals.
