초록

Mammals play a significant role in maintaining ecosystem balance by providing a variety of essential ecosystem services. Understanding the biodiversity of mammalian species requires examining how species partition and utilize available habitats. This study aims to assess the biodiversity of mammalian communities at a regional scale and to investigate the habitat preferences and inter-species co-occurrence patterns in Yeongyang-gun, South Korea. Mammal monitoring was conducted using camera traps at 108 stations across 22 grids at the study area from March to September 2021. A total of 13 species from 5 orders, 9 families, and 13 genera were recorded, including three endangered species: the leopard cat (Prionailurus bengalensis), the yellow-throated marten (Martes flavigula), and the long-tailed goral (Naemorhedus caudatus). The estimated biodiversity indices were: species richness of 13.00 (SE: 0.497, CI: 12.025–13.975), a Shannon index of 8.361 (SE: 0.301, CI: 7.770–8.951), and a Simpson index of 6.609 (SE: 0.285, CI: 6.051–7.167). Co-occurrence analysis revealed that the long-tailed goral exhibited a positive correlation with the roe deer (Capreolus pygargus) and the Siberian chipmunk (Eutamias sibiricus), indicating shared habitat preferences, while a negative correlation with the wild boar (Sus scrofa) suggested habitat partitioning. Additionally, the yellow-throated marten and raccoon dog (Nyctereutes procyonoides) were positively correlated with the Siberian chipmunk, suggesting that they may prefer similar habitats. Co-occurrence analysis not only enhances our understanding of biodiversity composition but also provides insights into the distribution and habitat use of endangered species, which are often difficult to survey, by examining the habitat-use patterns of co-occurring species. In conclusion, the biodiversity monitoring framework and ecological mechanisms presented in this study offer a valuable scientific foundation for ecosystem management. These findings underscore the importance of ongoing and long-term monitoring efforts to better understand and conserve mammalian biodiversity.
