Evaluation of habitat suitability for Capreolus pygargus in the eastern Yanshan Mountains based on MaxEnt model
Habitat suitability assessment can explore the suitable space and habitat quality for species from a macro per-spective.Assessing the environmental factors affecting species distribution and predicting suitable habitats are crucial for effective species conservation and habitat management.Understanding the habitat suitability of Capreolus pygargus is not only beneficial to the understanding and conservation of this species,but also helpful to explore the potential popu-lation of sympatric animals.In this study,114 valid sites of Capreolus pygargus were recorded by infrared camera meth-od in the eastern Yanshan Mountains in 2018,2022 and 2023,and the habitat suitability of this species in the area was evaluated using MaxEnt model.The results showed that the total suitable habitat area of this species was 8 523 km2,ac-counting for 14.59％of the total study area.Highly suitable habitats accounted for 1.83％,mainly distributed in the cen-tral and eastern parts of the country.Medium suitable and low suitable habitats accounted for 3.78％and 9.00％,respec-tively,and were mainly located in the surrounding area of high suitable habitats.Temperature annual range,maximum temperature of warmest month and vegetation type were the main environmental variables affecting the habitat suitability of Capreolus pygargus in the eastern Yanshan Mountains,while precipitation of the wettest month and altitude had rela-tively little effect.Capreolus pygargus preferred environments with temperature annual range between 39.4-44.0 ℃,maximum temperature of warmest month between 22.7 ° C and 27.7 ℃,precipitation in the wettest month exceeds 155.8 mm,and about 775.7 m above sea level in the eastern Yanshan Mountains.Common vegetation types in temper-ate zones such as broadleaved forest,coniferous forest,and shrubland were suitable for Capreolus pygargus.This study clarified the distribution and key environmental influencing factors of suitable habitat for Capreolus pygargus in the east-ern Yanshan Mountains,filled the gap in the study of the habitat of wild Capreolus pygargus in this area,and provided a theoretical basis for animal protection and habitat management in the future.
