Local Environmental Variables Predict Fish Species Richness and Composition in Sand Beaches of a Neotropical River

River Research and Applications, Volume 41, Issue 9, Page 1949-1958, November 2025.
ABSTRACT Local and regional species diversity is influenced by historical factors, resource availability, biotic interactions, the presence of resources, and adequate environmental conditions. We evaluated the effects of local environmental variables and spatial structure on fish species richness and composition along sandy beaches of a Neotropical ...
