|概要||In this study, the diet and sightings of red foxes inside and outside the fence were compared.
Generalized linear mixed models indicate that the sika deer remains, ground-dwelling insects (Scarabaeidae and
Rhaphidophoridae as a group, and Carabidae), and earthworms increased in the fox diet outside the fence, while the ingestion
of voles decreased. The difference in prey consumption by red foxes was probably caused by differences in prey availability
inside and outside the fence or the presence of available alternative food.
