“…Despite the lack of clear trophic niche partitioning, carnivores co-occur in the cool-temperate zone of Japan (Watabe & Saito 2021, 2022, Suzuki & Saito 2023). A high niche overlap has been identified among sympatric carnivores, which suggests that niche partitioning is not the only competition avoidance strategy in carnivore guilds (Vanak et al 2013, Davis et al 2018).…”

“…The study mainly focused on red foxes ( Vulpes vulpes ), Japanese martens ( Martes melampus ), and raccoon dogs ( Nyctereutes procyonoides ), which co-occur in the cool-temperate zone of Japan (Watabe & Saito 2021, 2022, Suzuki & Saito 2023). They are likely to be potentially competitive interactions (Donadio & Buskirk 2006) because of their taxonomy, body size (Ohdachi et al 2015), and dietary similarities (raccoon dog: Sutor et al 2010, red fox: Hisano et al 2021, Japanese marten: Hisano et al 2019, Tsuji et al 2019).…”

“…Thus, a decrease in the encounter rate during hunting season indicated that dense forests or other areas were spatially avoided (i.e., reserve effect). We also used cost‐effective camera surveys (Colomer et al 2021) along roads to assess finer‐scale spatial avoidance (i.e., road avoidance), as many wild animals including sika deer use roads for movements (Takahashi et al 2022, Suzuki and Saito 2023). If the number of deer photographed (i.e., detection rate) decreased during hunting season and areas with higher hunting pressures, we inferred that deer spatially avoided roads.…”

Evaluation of multiple behavioral responses of sika deer to human hunting pressures

Several ungulate populations have become overabundant worldwide, resulting in ecological and social effects. Wildlife managers must establish effective population control programs to mitigate these negative influences. Hunting is a significant mortality factor for ungulates, which exhibit sensitive behavioral responses toward hunting activities. Wildlife managers need a comprehensive understanding of the ungulate responses to different hunting pressures across seasons. We developed a conceptual method to evaluate multiple behavioral responses to human hunting pressures and applied this to sika deer (Cervus nippon) in Hokkaido, Japan, during August and November in 2015. We measured flight behavior, spatial avoidance, and temporal activity shift during non‐hunting and hunting seasons in 4 regions with different hunting pressures. Although we did not observe a clear difference in flight initiation distance among study areas or seasons, sika deer showed significant spatial avoidance during the hunting season in areas with high hunting pressure. Furthermore, sika deer were more active at night in areas with higher hunting pressures, regardless of the season. Collectively, these results suggest that sika deer responded to hunting pressure by changing diel activity to nocturnal throughout the year and avoiding risky areas (i.e., around hunting roads) during hunting season, rather than by increasing flight distance when they encounter humans. Our method can be used for a more efficient population control program for wildlife managers, as it considers the spatiotemporal variations of flexible ungulate behaviors in response to hunting pressures.

“…Similarly, our results indicate that the yellow-throated marten (M. avigula) and leopard cat (P. bengalensis) may use ridges as convenient routes through the mountain for movement; however, mammals prefer to move through gentle-slope areas to other habitats when these are not accessed by humans (Tobler et al 2018). In particular, carnivores, such as the red fox (Vulpes vulpes) and ocelot (Leopardus pardalis), prefer at areas but are not found when tourists and hikers use the trail (Harmsen et al 2010;Suzuki et al 2023). Of the species that preferred a gentle-slope area, yellow-throated martens (M. avigula) avoided trail hikers because they were sensitive to human disturbance.…”

National parks (NP) and military areas (MA) preserve natural ecosystems. Although both regions have positive and negative effects on animal communities, studies comparing their impacts on conservation are limited. We monitored mammalian communities using 21 sensor cameras in a MA (6 sites) and NP (15 sites) located on Gyeryongsan Mountain, South Korea from May to November 2021 to compare the conservation of medium and large-sized mammals between the two regions. Forty-one environmental variables, including anthropogenic and geographical factors, were extracted from different spatial ranges (50, 500, and 1000 m). A linear model and non-metric multidimensional scaling were used to identify the factors influencing community diversity. We also analyzed species habitat type preferences using a multispecies occupancy model and compared temporal activities in the two regions. Species diversity was similar between the two sites, with most animals preferring habitats with lower slopes located at greater distances from human trails. Only the Korean hare (Lepus coreanus) preferred the NP habitat of the eight species found. Active periods were similar for the species in both regions, except for differences in some carnivore species. Although not all species were affected by human activity, most preferred the MA over the NP. The carnivores were especially able to flexibly alter their active periods and locations in response to human activities, especially in the NP where human activity was more prevalent. Thus, strategies should be implemented to improve NP conservation success, such as spatial and temporal accessible and inaccessible section separation.
