Patterns of fish species richness in rivers of the central region of Argentina

Patterns of fish species richness in rivers of the central region of Argentina

We analyzed the variation of fish species richness and trophic structure along an upstream-downstream gradient and identified the factors associated with the pattern observed. The fish community composition varied along a headwater-downstream gradient. Species richness and trophic structure decrease...
