Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: July 17, 2025 | Last Modified: 20231206
Methylmercury concentrations and stable isotope ratios were measured from back feathers of California black rails (Laterallus jamaicensis coturniculus) and six taxa of their invertebrate prey (Amphipoda, Arachnida, Coleoptera, Diptera, Gastropoda, and Hemiptera). Samples were collected from three wetlands in the spring and summer of 2005 and 2006.
