Environmental DNA metabarcoding results of fish prey DNA in common loon (Gavia immer) fecal and cloacal swab samples from the Whitefish Chain of Lakes, Crow Wing County, Minnesota

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: July 16, 2025 | Last Modified: 20230815
The dataset contains sequencing read counts of fish prey eDNA metabarcoding (using primers targeting the 16S rRNA mitochondrial gene) that were extracted from fecal and cloacal swab samples collected from common loons (Gavia immer) captured on the Whitefish Chain of Lakes, Crow Wing County, Minnesota during 2015-2106. Sample type (cloacal or fecal); loon identification, age, and sex; capture date and location; and prey detections for each sample are provided.
