Abstract:

Aims: In order to determine the mammalian fauna and diversity patterns in the northeastern Taihang Mountains, we studied the wild mammalian resources in this area from July 1st to October 30th, 2019.
Methods: We used a combination of line-transect surveys, camera trap and other methods. The number of species and distribution patterns of mammals in the Taihang and Yanshan areas were compared using biodiversity indices.
Results: A total of 68 species of mammals were recorded in the region, belonging to 7 orders and 22 families. The majority of species were Rodentia (24 species), while only one Primate species (Macaca mulatta) was found. In this region, two species (Panthera pardus, Cuon alpinus) were listed as Class I National Key Protected Species in China and 10 species, including Naemorhedus griseus, were listed as Class II. The mammalian fauna in Taihang and Yanshan areas was similar with an average faunal resemblance (AFR) of 0.844, but the number of species in Taihang (66) was greater than that in Yanshan (50). The diversity of family index (DF = 2.994 ± 0.251, n = 13) and genus index (DG = 2.443 ± 0.161, n = 13) of Taihang were slightly higher than those in Yanshan (DF= 2.458 ± 0.170, DG= 2.259 ± 0.149, n = 10), but the differences were not statistically significant (P > 0.05). Taihang’s DG-F index (0.145 ± 0.022, n = 13) was significantly higher than that of Yanshan (0.078 ± 0.014, n = 10) (P < 0.05). Our results indicated that species composition in the two areas was similar in family and genus diversity. Whilst, the species diversity of Taihang was higher than that of Yanshan, and dominated by mammals from the Palaearctic region. Although there were 10 types of distributions in Taihang and Yanshan, the former’s proportion of species from the Oriental region (19.11%) was slightly higher than that in Yanshan (17.64%) due to the relatively lower latitude.
Conclusion: There are environmental stress on the distribution and biodiversity of wild mammals in the northeastern Taihang Mountains. It is suggested that the specific survey should be carried out in this area to determine the stressors and the mechanism of influence, on this basis, the reasonable strategies can be determined and the efficiency of conservation can be improved.
