The northern pika is a small lagomorph living in rocky talus with cooler microclimates, often at habitat edges. While these edges can improve connectivity, they may also increase predation, competition, and threaten pika populations. In this study, we analyzed the influence of edge effects to the interspecific interaction and quantified the temporal overlap patterns of Northern pika and other animals in the edge of habitats. In our camera trapping study, a total of 13 species were found; including 5 birds and 8 mammals. From 3 different habitat edges, we found 11 species can be found in forest vegetation, 8 species can be found in mix vegetation, and 7 species can be found in open vegetation. For the temporal interaction with minimum of 15 independent photos criteria, we analyzed 5 species. Northern pika, siberian chipmunk, and olive-backed pipit considered as diurnal, while sika deer and red fox considered as crepuscular. Diel activity overlap between northern pika and red fox has the highest overlap coefficient (Δ1 = 0.8), the medium overlap with sika deer and Siberian chipmunk showed the same amount (Δ1 = 0.62), and the lowest overlap with olive-backed pipit (Δ1 = 0.48). Even though red fox has a high overlap but there is no evidence regarding the predatory but the presence of sables as possible predators at the forest edges has been discovered. The overlapping with other species showed the possibility of resource sharing. Our results suggest that edge effects could influence interspecific interactions, alter species dynamics, and competitive behavior significantly in Daisetsuzan National Park, Japan.
