2003 Blood Corticosterone Common Loons: Data

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.
