Abstract Unlike the top‐down cascading effects driven by apex predators, bottom‐up on biological interactions originating from herbivory large mammals, especially within mammalian assemblages, have received less attention. This study aimed to identify multifaceted impacts sika deer ( Cervus nippon ) during midwinters, when their were expected be strong due deficient dietary resources. We focused interference and exploitative competition caused habitat use of four sympatric mammal species, namely two herbivores (Japanese serow, Capricornis crispus , Japanese hare, Lepus brachyurus angustidens mesocarnivores (red fox, Vulpes vulpes marten, Martes melampus ). To estimate wintering behaviors these mammals pressure, we performed snow tracking counted fresh feeding marks midwinter in 2022 2023. conducted surveys 201‐km transects with different stages population recovery (i.e., densities) heavy snowfall regions Japan. then systematically quantified deer‐driven using piecewise structural equation modeling (SEM). recorded 1700 tracks target 1327 trees marks. Based records, constructed an SEM acceptable performance (Fisher's C = 27.1, P 0.30). The suggested some possibilities that mediated constrained habits similar deer, i.e., serow (effect size, −0.13) hares (−0.14). In addition, through constricting hares, reduced occurrence key foxes (−0.12) martens (−0.10). Thus, our observations provide novel evidence food webs are regulated herbivore‐driven cases where plant primary productivity is limited snowfall.
