“…The Maxent model showed a good fit in terms of the AUC (0.81), Cohen’s Kappa, and TSS values, and we benchmarked our findings based on the current distribution patterns of the species and entropy values exceeding the Maxent threshold (0.65). Using this method, we identified the northeastern and southern regions as suitable habitat zones under current climatic conditions, where deer populations already exist 16 , 62 , 63 , while the habitat loss was identified in each examined future scenario. When examined under the RCP 4.5 scenario, the habitat status of the sika deer was predicted to be better in 2070 than in 2050.…”

Invasive species and climate change are primary factors influencing biodiversity, and examining the behavior of invasive species is essential for effective conservation management. Here, we report the global distribution of the sika deer (Cervus nippon) based on locations reported in published literature (Google Scholar), the Global Biodiversity Information Facility (GBIF) database, and the International Union for Conservation of Nature report. We used the maximum entropy (Maxent) model to examine the impact of climate change on sika deer habitats in South Korea based on GBIF occurrence data and WorldClim bioclimatic variables. Habitat suitability analysis was performed using the Maxent model under Representative Concentration Pathways (RCPs) 4.5 and 8.5 (for predicted climatic conditions in both 2050 and 2070) to project the effects of different climate change scenarios on South Korean sika deer habitats. We identified that the sika deer is distributed in 39 countries worldwide. Due to climate change effects, South Korean sika deer habitats will decline by approximately 24.98% and 20.63% (under RCP 4.5) and by 50.51% and 57.35% (under RCP 8.5) by 2050 and 2070, respectively. Our findings shed light on sika deer ecology and provide reference data for future conservation management strategies and policy design.
