Endemic Fishes of Sinocyclocheilus (Cypriniformes: Cyprinidae) in China [Chinese] Species Diversity, Cave Adaptation, Systematization and Zoogeography

About this book

Language: Chinese with English summary

The cyprinid genus Sinocyclocheilus is endemic to China with a distribution limited to various karst areas in Yunnan and Guizhou Provinces and the Guangxi Zhuang Autonomous Region. Examination of specimens from almost all nominate species, including most of the type specimens, leads to the recognition of 49 valid species.

The distribution of Sinocyclocheilus species is mainly influenced by climate, water system topologies and karst processes. Modern species' distributions exhibit recognizable horizontal and vertical aspects, with the former nicely matching the E-type structure of the Guangxi landform and the latter intimately related to assorted altitude-dependent karst features.

Other aspects of Sinocyclocheilus biology were also investigated, including reproductive and feeding behaviour as well as tolerance to an array of environmental factors. Findings from these studies provide information crucial to future conservation planning.
