Trophic relationships in an Arctic food web and implications for trace metal transfer

Institute of Arctic Biology UAF (IAB) - Arctic mammals that were harvested for subsistence were analyzed for Ag, Cd, and THg. Stable carbon and nitrogen isotopes were evaluated to establish trophic interactions within the Arctic food web. Food web magnification factors (FWMFs) and biomagnification factors for selected predator–prey scenarios (BMFs) were calculated to describe pathways of heavy metals in the Alaskan Arctic. Species...

Trophic transfer of persistent organochlorine contaminants (OCs) within an Arctic marine food web from the southern Beaufort–Chukchi Seas

University of Guelph (GUELPH) - Stable isotope values and concentrations of persistent organochlorine contaminants (OCs) were determined to evaluate the near-shore marine trophic status of biota and biomagnification of OCs from the southern Beaufort–Chukchi Seas (1999–2000) near Barrow, AK. The biota examined included zooplankton (Calanus spp.), fish species such as arctic cod (Boreogadus saida), arctic char (Salvelinus...
