Hydrologic connectivity affects fish assemblage structure, diversity, and ecological traits in the unregulated Gambia River, West Africa
Original language description
The Gambia River of West Africa, scheduled to undergo construction of a major dam, is a large tropical river with lateral connectivity across its floodplain and a natural flow regime. We compared patterns of fish diversity, habitat use, fish assemblage structure, and the distribution of trophic position and body morphology in riverine and floodplain habitats in Niokolo Koba National Park, downstream of the planned dam. A total of 49 fish species were captured. Fish species exhibited a range of habitat use patterns including habitat generalist, specificity to particular habitats, and apparent lateral migration among habitats between seasons. Species richness was homogenous among habitats in the wet season yet increased with isolation from the main channel in the dry seasons. Our results suggest that homogenization of floodplain habitats after damming could lead to both decreased taxonomic diversity and decreased functional disparity of the fish assemblage.
