Mingfu Li, Mei Xiao, Li Zhao, Yiming Wu, Long Jin, Chengzhi Yan, Wenbo Liao

TL;DR
This study explores how amphibian diversity and distribution vary with elevation in China's Tangjiahe National Nature Reserve, identifying 25 species and highlighting conservation concerns.
Contribution
The study documents three newly recorded amphibian species and provides insights into their altitudinal distribution patterns in the reserve.
Findings
Species diversity was highest in Caijiaba and lowest in Shuichiping.
Species richness peaked at 900–1100 m and 1900–2100 m elevation bands.
Fourteen species were found in terrestrial-farmland and aquatic-lotic habitats.
Abstract
Understanding amphibian distribution and diversity along altitudinal gradients is crucial for developing effective conservation policies. This study investigated species distribution and diversity of amphibians in the Tangjiahe National Nature Reserve, located in western China. We identified 25 amphibian species across 8 families and 2 orders, including three newly recorded species: Fejervarya kawamurai, Polypedates braueri, and Boulenophrys minor. We found that eight species were classified as “threatened” species according to International Union for Conservation of Nature (IUCN) criteria, and fourteen species inhabited terrestrial-farmland and aquatic-lotic environments. Species diversity analysis revealed the highest diversity in Caijiaba and the lowest in Shuichiping. Species richness peaked at elevation bands of 900–1100 m and 1900–2100 m, while elevations above 2300 m exhibited…
