Natural disasters can degrade primate habitat and alter feeding behavior. Here, we examined the influence of unusually heavy snow on diet and feeding-site use by Japanese macaques (Macaca fuscata) in northern Japan. To compare the winter-feeding behavior under different snow conditions, we recorded the plant species foraged on by macaques in multiple(More)
This study aimed to reveal the soil seed accumulation processes for endozoochorous plants in the heavy-snowfall forests of Japan, where seed dispersal agents are few when compared to tropical forests. We assessed (1) primary seed dispersal by Japanese macaques (Macaca fuscata) by identifying dispersed seeds found in their feces, and (2) secondary seed(More)
In early spring, snow-buried mammal feces simultaneously emerge on the ground with the melting of the snow across regions with heavy snowfall. Here, we evaluated the ecological implications of this phenomenon for the cool-temperate forest ecosystem in terms of the resource use of dung beetles (Coleoptera: Scarabaeidae), which play key roles in secondary(More)
Japanese macaques (Macaca fuscata) in their northernmost habitats represent a keystone species and play a central role in heavy snowfall ecosystems. However, distributions have been restricted by pre-war hunting, and populations are facing issues of natural forest losses caused by new dam constructions and massive conifer plantations. In the present study,(More)
