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

Abstract

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.
