The Luoxiao Mountains play an important role in maintaining and supplementing the fish diversity of the Yangtze River Basin, which is also a biodiversity hotspot in China. However, fish biodiversity has declined rapidly in this area as the result of human activities and the consequent environmental changes. Beta diversity was a key concept for understanding the ecosystem function and biodiversity conservation. Beta diversity patterns are evaluated and important information provided for protection and management of fish biodiversity in the Luoxiao Mountains. The results showed that the spatial turnover component was the main contributor to beta diversity of

Biodiversity patterns and their formation mechanisms have been one of the hot issues, and it is also an important foundation for conservation (
Beta diversity is an important tool for conservation planning (
The Luoxiao Mountains range is located in the southeast of China’s mainland and has a long history and complex environmental factors (
The Luoxiao Mountains (25°32'–29°28'N, 113°09'–114°26'E) are a large system of mountain ranges, located in the southeast of China’s mainland with an overall north-south trend, stretching across Hubei, Hunan, and Jiangxi provinces. It consists of Mufu Mountain, Jiuling Mountain, Wugong Mountain, Zhuguang Mountain, and others. The total length of the Luoxiao Mountains is 400 km and altitude ranges are 82–2120 m. Lingfeng Peak (2122 m) is one of the highest mountains in the southeastern Eurasia. Its average precipitation range is 1341–1943 mm and forest coverage in the watershed reaches 90% (Table

Sampling sites were selected by considering habitats, variations, and anthropogenic activities in the Luoxiao Mountains. Fish samples were collected from April 2014 to 2017 in eleven streams of the Luoxiao Mountains. We selected eleven streams (42 sampling sites) (Figure
Map showing the sampling location of the streams of the Luoxiao Mountains.
Beta diversity is represented by the difference in species composition between different communities, which was determined by species turnover (species replacement) and nestedness (richness difference;
BAS frameworks (Sørensen index):

The fish specimens sampled and identified in the Luoxiao Mountains were categorized into 113 species and 17 families (Figure

Studies on fish composition and diversity in streams is the basis for the conservation and management of stream fishes (
Abiotic and biotic factors and their ecological processes in different stream sizes varies substantially (
The modern freshwater fish fauna of Eurasia originated in the early Tertiary (
The headwater stream is a tributary of a larger river, which is often located in a mountainous area with high altitude. Compared with large rivers, it had relatively simple habitat structure, poor nutrition, obvious hydrological change, and low species diversity (
Freshwater fishes were thought to be the world’s most threatened group of vertebrates after amphibians (
