Predicting the Potential Distribution of Endangered Parrotia subaequalis in China

Climate change poses a serious threat to species, especially for endangered species. This is particularly true the tree Parrotia subaequalis, endemic China. To date, little known about its pattern of habitat distribution, and how it will respond under future climate still remains unclear. Based on six variables 115 occurrence records, we used MaxEnt model predict potential distribution P. subaequalis in The modeling results showed that first three leading factors influencing were precipitation driest quarter (Bio17), mean temperature (Bio9), annual average (Bio1). actual area this was smaller than projected suitable range (2.325 × 104 km2), which mainly concentrated west southeast Anhui, southwest Jiangsu, northwest Zhejiang, eastern Our study also indicated populations regions (Central-China Mountain Area (CC), Dabie (DB), Tianmu (TM)) responded differently change. DB population changed insignificantly habitat, while TM increased slightly area, migrating northeast whole. habitats became more fragmented all scenarios those current condition. Due geographical isolation limited spread, plausible grow CC conditions. Accordingly, our findings highlighted two local presented different responses global warming. Therefore, can improve conservation management China be helpful other species with
