| Research Abstract |
Japanese macaque populations living in snowy areas became locally extinct in several regions of eastern Japan. In recent years, the remnant populations have gradually recovered. To predict the influence of the current population recovery on local biological interactions, this study evaluated the grazing and detritus food chains associated with macaque feeding. The current results suggest that macaques have a key role to support the local plant diversity. In particular, macaques could strengthen the seed dispersal process because they directly transport seeds as primary dispersers and their feces enforce the biomass of dung beetle assemblages which are act as secondary seed dispersers.
