Fish dispersal in a seasonal wetland: influence of anthropogenic structures
Original language description
Knowledge of fish dispersal routes in temporary habitats is important for understanding the ecology of species and for conducting conservation. We evaluated fish dispersal in a network of seasonal habitats and a permanent fish source (a lake) in a subtropical wetland, in Florida (May 2002 - May 2003). Fish dispersal routes were influenced by local physical conditions, anthropogenic alterations and fish species and size. Fish from the source dispersed into 9 of the 25 seasonal sites evaluated, via temporarily formed dispersal corridors. Low connection depths along the corridors were a key factor, allowing small-bodied species to travel farther than large-bodied fish. Fish travelled distances of 0,7-4km. Anthropogenic structures both enhanced and blockedfish dispersal routes. We demonstrated extensive opportunistic use by fish of seasonal wetlands. Anthropogenic alterations to the landscape can provide habitat for native fish and also allow dispersal of non-native fish.
