Abstract
The time allocation of species in a day is the most important survival strategy for wild animals, and it is very important for understanding the behavior ecology of species. In order to determine the dominant species in Wanglang Nature Reserve and the relationship between the activity intensity of the dominant species and the habitat status, from May 2018 to July 2019, the infrared camera monitoring and sample surveys methods were used to investigate the species and habitats of large and medium-sized beasts and understory birds in Wanglang Nature Reserve. The habitat conditions of 3 species (two wild dominant species and one domesticated species) with different activity intensities were evaluated. Moreover, the activity intensity of wild dominant species in Bos taurus habitat and other habitats were compared. The principal component analysis showed that the dominant species in Wanglang Reserve were blood pheasant Ithaginis cruentus and tufted deer Elaphodus cephalophus. The intensity of species activity was divided into high, medium and low intensity based on the relative abundance index of time. The difference in habitat conditions between blood pheasants and tufted deer in areas with different activity intensities was mainly manifested in terrain conditions and food resources. The difference in the habitat status of cattle in different activity intensity areas was mainly manifested in herb coverage. Nuclear density estimates indicated that blood pheasants and tufted deer had a high degree of overlap in their activity curves when using cattle habitats and other habitats. However, when using the cattle habitat, the activity intensity of the two peaks was higher than that of other habitats. The results showed that: (1) The activity intensity of dominant species in the area can represent areas with good terrain conditions and poor food resources. (2) When formulating habitat restoration policies in the protected area, priority can be given to areas where the dominant species have high activity intensity. (3) When restoring the habitat, focus should be placed on restoring the habitat used by the cattle species.
