A Macroecological Approach to Understanding Drivers of Riverine Fish Community Composition
Viewing rivers as a mosaic of hydrogeomorphic patches has allowed for a more complete and in-depth approach to advancing riverine ecological research. Changes in valley scale hydrogeomorphic patches, (or functional process zones, FPZs), alter the riverine habitat features that influence the development and structure of communities as a result of environmental selection for specific ecological and life history traits. Using the AFS Standard Sampling Protocol for wadeable streams, we sampled contrasting (constricted and wide valley) FPZs in both upland and lowland areas within three terminal basin rivers in the Great Basin U.S.A. Functional diversity was calculated using fish trait and abundance data within the statistical package FD, and evaluated alongside a metric of riverine complexity determined from valley and reach scale hydrogeomorphic data taken on site and from remote sensing databases. Analyzing community functional diversity alongside riverine complexity revealed a configuration of fish communities structured by hydrogeomorphic patches. The unique scale of this project provides new perspectives in riverine ecology for both theoretical and management scenarios when thinking about the structure and location of riverine fish communities.
