AN ANALYSIS OF FUNCTIONAL DIVERSITY IN RIVERINE FISHES FROM THE GRASSLANDS TO THE GREAT BASIN
Functional diversity (FD) has been utilized to gauge the health and stability of fish communities in many different environments, but has not yet been formally applied to fishes within terminal basin rivers. To accomplish this goal, we sampled fish in the Carson, Bear, and Humboldt rivers and investigated how FD changed between and within each system. As part of a larger project, we also sampled grassland and mountain steppe sites to allow FD comparisons between ecoregions. We used fish traits associated with each species’ reproduction and feeding habits to gauge community functionality. As expected, FD was found to strongly correlate with species diversity. In most comparisons the more speciose lowlands in particular provided greater FD. However, a community containing redundant species that offer no novel traits to the community can cause exceptions to this rule. This project should serve as a foundation for future large-scale FD studies in each of these ecoregions, and the terminal basin especially.
