Bioenergetic 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 کاملCues used by the black fly, Simulium annulus, for attraction to the common loon (Gavia immer).
The parasitic relationship between a black fly, Simulium annulus, and the common loon (Gavia immer) has been considered one of the most exclusive relationships between any host species and a black fly species. To test the host specificity of this blood-feeding insect, we made a series of bird decoy presentations to black flies on loon-inhabited lakes in northern Wisconsin, U.S.A. To examine the...
متن کاملThe oral bioavailability and toxicokinetics of methylmercury in common loon (Gavia immer) chicks.
We compared the toxicokinetics of methylmercury in captive common loon chicks during two time intervals to assess the impact of feather growth on the kinetics of mercury. We also determined the oral bioavailability of methylmercury during these trials to test for age-related changes. The blood concentration-time curves for individuals dosed during feather development (initiated 35 days post hat...
متن کاملHand‐rearing, growth, and development of common loon (Gavia immer) chicks.
Common loon chicks were reared in captivity in association with studies to evaluate the effects of radiotransmitter implants and to assess the ecological risk of dietary methylmercury. Here we report on hatching and rearing methods used to successfully raise chicks to 105 days of age. We experienced a 91.5% hatch rate, and 89.6% of loon chicks survived to the end of the study at 105 days. Basel...
متن کاملLead poisoning in common loons (Gavia immer).
Two emaciated common loons (Gavia immer) were believed to have died of lead poisoning when fragments of fishing lines and lead sinkers were discovered in their stomachs. Later a third emaciated loon, which had only the remnants of fishing line in its stomach, was suspected of being a possible lead-poisoning victim when all other test results were negative. The liver lead levels in the first two...
