Abstract:In order to understand the species richness patterns along elevational gradients and the distribution pattern of species alternation of non‑volant small mammals in the Xiaoxiangling Mountains, we investigated the diversity and community composition of small mammals by snap traps from July to September in 2019 and 2020. A total of 53 sampling plots were set along the elevational gradient from 1 300 m to 4 100 m with an interval of 400 m. Finally, 317 individuals belonging to 23 species (including the new record species Vernaya fulva), 15 genera, 7 families, and 3 orders were captured. The species richness and diversity of small mammals peaked at the elevation of 2 500‒2 900 m, and then decreased gradually with the increase of the elevation, displaying a single hump⁃typed distribution pattern. Species alternation between adjacent elevations also showed higher β‑diversity at mid‑elevation. Furthermore, the community similarity along the whole gradient of the Xiaoxiangling Mountains declined with the increase of elevational distance. This study suggests that special attention should be paid to the intermediate‑elevation area for biodiversity conservation and management in the future.
