 note = {We made an inventory of ants that inhabit Tono, Iwate Prefecture. We also investigated the species eaten by Japanese black bears (Ursus thibetanus) and their nesting environment. We consider the environments in which bears use ants as an important food resource in summer. As a result, we found 18 species of ants in the study area and 11 species from bear scats. We suggest that the length and density of ants affects their selection by bears. Each average length of ants from scats is larger than 3mm, and their percentage appearance is high. Ants that nest on the ground surface often selected Japanese red pine forests and Japanese larch forests, rather than broadleaf tree forests, as their nesting environments. We found that ants selected their nesting environment based on temperature and humidity, thus showing a preference for Japanese red pine or Japanese larch forests, which often grow in sunny and dry locations. Almost all ants in coarse woody debris were species that bears have eaten, and bears were suggested to effectively eat ants in coarse woody debris. On the whole, coniferous forests give ants a nesting environment. Because bears seem to use environments containing many ants, coniferous forests seem to be one of the most important habitats for bears in summer.},
