Abstract

Understanding the causes and consequences of current biogeography is of paramount importance in species ecology, evolution and conservation. Yunnan province is a scarce example to testify biogeography patterns, causes and conservation challenge for its complex geography, high biodiversity and increasing human activities. Freshwater fishes are among the most effective faunas to explain biogeography for their limited ability to disperse. In the present study, totally 375 fish species in 146 genera, 26 families and 9 orders were included. Four key areas with higher diversity were randomly distributed in the province. Six environmental parameters as minimum temperature, mean precipitation, mean altitude, altitude range, river length, maximum slope, and their any combinations could effectively explain the current fish spatial patterns. A total of 625 individuals belonging to 30 dominated genera were grouped into six communities, each showing a better use of living spaces and food. Historical event was the primary factor to determine the current spatial distribution pattern of freshwater fishes in Yunnan Province, followed by the changing environment. Relationships among fish species with different personalities finally made the fauna more stable. The biogeography will move to a confusion pattern under the increasing human intervention and consequent environment changes.
