An Ecological Perspective on Diversity and Distributions

This chapter examines the distribution of species and higher-level taxa among major geographic and habitat categories, using gymnotiform electric fishes as a case study. It proposes a simplified four-category classification of aquatic habitats, intended as a conceptual framework for understanding ecological distributions and describes the diversity and composition of their fish faunas. It highlights the role of habitat in constraining the distributions of individual species and higher taxa and the consequences this has for the formation of regional species assemblages.

Keywords: distribution of species; habitat categories; gymnotiform electric fishes; aquatic habitats; fish faunas; regional species assemblages
