AQUATIC MACROINVERTEBRATE COMMUNITY OF A WILD AND SCENIC RIVER IN THE SOUTHWESTERN UNITED STATES
Our research presents the community structure and diversity for aquatic macroinvertebrates in the Wild and Scenic Verde River, Arizona. Our goal was to understand the relationships between aquatic macroinvertebrate communities and the three main habitats on the river: riffles, runs, and pools. Samples were collected in fall 2017 and spring 2018 from three reaches on the river. Three replicates taken from microhabitats (riffle-run-pool) per-reach. Results showed a diverse community with 106 taxa, 89 genera, and ~40% of the community belonging to Ephemeroptera, Plecoptera, and Trichoptera. Nonmetric multidimensional scaling analysis found distinct, low-stress, ordinations with high correlations between species occurrences and the three microhabitats. This work establishes baseline knowledge that will be used in the development of models to predict river health values under current and possible future flow scenarios. Our findings and the results of the model will inform managers in the development of policies allowing sustainable allocation of water to the river and the surrounding communities.
