贡嘎山国家级自然保护区中华小熊猫的栖息地适宜性与活动节律OA

Studying habitat suitability and activity rhythms of wildlife holds critical significance for species conservation and ecosystem management.From 2013 to 2024,we systematically investigated the Chinese red panda(Ailurus styani)in the Gongga Mountain National Nature Reserve using infrared camera traps,analyzing habitat suitability through Max-Ent modeling,and temporal activity patterns via kernel density estimation.Our analysis revealed that the Chinese red panda's potential habitat spans 869.68 km2(21.26％of the reserve's 4 091 km2),with the central-southern area as the core suitable zone.Habitat selection was predominantly driven by topographic factors(elevation:27.6％,distance to wa-ter:26.9％),and climatic factors(isothermality:15.6％,temperature seasonality:16.1％),with anthropogenic factors ex-hibiting minimal influence(distance to road:7.4％,distance to settlement:0.2％).We also found that Chinese red pan-das displayed predominantly diurnal activity(β=0.855 3),peaking around midday(10:00-11:00 and 13:00-14:00).Significant seasonal variation in activity patterns emerged(△4=0.79,P=0.016 3),with increased nocturnality during cold seasons.We recommend prioritizing monitoring efforts in the central-southern core habitat area.This research elu-cidates the Chinese red panda's potential habitat distribution and activity rhythms in the reserve,offering vital insights for its conservation.
