2003 Blood Corticosterone Common Loons: Data

Published by U.S. Geological Survey | Department of the Interior | Catalog Last Checked: August 01, 2026 at 05:11 AM | Dataset Last Updated: April 13, 2021 at 12:00 AM
To help determine whether Hg had a causal effect on corticosterone, we investigated the impact of experimental Hg intake on the corticosterone stress response in captive juvenile loons. Juveniles were subjected to three different feeding regimes: 0, 0.4 and 1.2 µg Hg (as MeHgCL)/g wet weight (ww) fish. We then measured baseline and 30 min post-solitary confinement stressor corticosterone concentrations. The data set consists of times of blood draws and dietary Hg levels. Blood samples and data set were provided to the senior author for analysis.
