Loon Mortality in New England Mortality of the Common Loon in New England, 1987 to 2000
Diagnostic findings are presented on 522 common loons (Gavia immer) found dead or moribund in New England (Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont, USA) between 1987 and 2000. Common loon numbers and range in New England have decreased from historic levels over the last century due to a number of proposed factors. Goals of this study were to identify and cate...
متن کاملBioenergetic and pharmacokinetic model for exposure of common loon (Gavia immer) chicks to methylmercury.
A bioenergetics model was used to predict food intake of common loon (Gavia immer) chicks as a function of body mass during development, and a pharmacokinetics model, based on first-order kinetics in a single compartment, was used to predict blood Hg level as a function of food intake rate, food Hg content, body mass, and Hg absorption and elimination. Predictions were tested in captive growing...
متن کاملBiomarkers of Lead Exposure and DNA Methylation within Retrotransposons
BACKGROUND DNA methylation is an epigenetic mark that regulates gene expression. Changes in DNA methylation within white blood cells may result from cumulative exposure to environmental metals such as lead. Bone lead, a marker of cumulative exposure, may therefore better predict DNA methylation than does blood lead. OBJECTIVE In this study we compared associations between lead biomarkers and ...
متن کاملGuidelines for Constructing and Deploying Common Loon Nesting Rafts
ArtiÞ cial nesting islands, or rafts, are deployed in Gavia immer (Common Loon) territories to lessen the incidence of nest failures due to mammalian predation and water-level ß uctuations. The effectiveness of this management tool has been demonstrated in other studies; however, improper construction and deployment can result in lowered nesting success. Despite widespread use of rafts, detaile...
