Abstract
Exploring species richness patterns across space and time can help in understanding species distribution and in formulating conservation strategies. Among taxa, amphibians are of utmost importance as they are highly sensitive to environmental changes due to their unique life histories (Zhong et al., 2018). Here, we investigated the spatial and temporal patterns of amphibian species richness on Tianping Mountain in China. Specifically, we established 10 transects at low to high elevations, and sampled amphibians in April, June, August, and October 2017. Our results demonstrated that amphibian species composition and richness varied significantly at both spatial and temporal scales and were associated with gradients of environmental change in microhabitats on Tianping Mountain.
Highlights
Exploring species richness patterns across space and time can help in understanding species distribution and in formulating conservation strategies
Total amphibian species richness increased significantly along elevational gradients when incorporating data from all four sampling sessions (R2=0.53, P=0.010; Figure 1D), indicating that more species were detected at high elevation sites
Our results indicated that amphibian species assemblages varied along elevational gradients
Summary
Exploring species richness patterns across space and time can help in understanding species distribution and in formulating conservation strategies. In the present study, we focused on the spatial and temporal (seasonal) changes in species richness in amphibians distributed on Tianping Mountain, China.
