江西九连山国家级自然保护区斑林狸种群密度估算与栖息地适宜性研究
Study on species density estimation and habitat suitability prediction of spotted linsang(Prionodon pardicolor)in Jiangxi Jiulianshan National Nature Reserve
摘要
Abstract
The spotted linsang(Prionodon pardicolor)was once widely distributed in southern and southwestern China as well as South and Southeast Asia.However,its population has drastically declined in recent years.From April 2023 to March 2024,we estimated the population density using infrared cameras and random encounter models,and generated current(2020s)and future(2050s)habitat suitability models using MaxEnt for the spotted linsang in the Jiangxi Jiulian-Shan National Nature Reserve.This study showed that the population density of spotted linsang was(2.039±0.243)civets/km2 in the Reserve.The MaxEnt model showed high accuracy in predicting suitable habitats for both cur-rent and future periods.Under future climatic conditions,suitable habitats for spotted linsang within the reserve may de-crease by 14.44％,while those outside the reserve will decrease by 46.61％compared to the current period.High-suit-ability habitats will contract inward in the reserve and migrate to higher altitudes.The main environmental factors affect-ing the current distribution are distance to rivers,isothermality,vegetation type,precipitation in the driest season,and slope direction.For future distributions,the primary influencing factors are distance to rivers,mean temperature in the driest season,vegetation type,and the coefficients of seasonal variation of aspect and precipitation.This study prelimi-narily investigated the field ecological habits of spotted linsang and provided scientific support for the conservation of spotted linsang in the JiulianShan Reserve and beyond.关键词
