Population genetic analysis of three aquatic macroinvertebrate species from samples in Grand Canyon (Arizona, USA) tributaries and nearby reference streams, 2016-2021

Published by U.S. Geological Survey | Department of the Interior | Catalog Last Checked: August 01, 2026 at 05:48 AM | Dataset Last Updated: March 23, 2022 at 12:00 AM
This dataset contains single nucleotide polymorphism (SNP) information for aquatic insect species collected in tributaries of the Colorado River in Grand Canyon (Arizona, USA), as well as SNP information for individuals collected from reference reaches of the Upper Colorado River Basin in Utah. This dataset focuses specifically on three species that were common and widely distributed throughout tributary streams in Grand Canyon: a mayfly (Fallceon quilleri), a caddisfly (Hydrospyche oslari), and a water strider (Rhagovelia distincta).
