biomagnification of polybrominated diphenyl ether and hexabromocyclododecane flame retardants in the polar bear food chain in svalbard, norway.concentrations of brominated flame retardants (bfrs), including polybrominated diphenylethers (pbdes) and hexabromocyclododecane (hbcd), were investigated in an arctic marine food chain consisting of four invertebrate species: polar cod (boreogadus saida), ringed seals (pusa hispida), and polar bears (ursus maritimus). the most abundant bfr, brominated diphenyl ether (bde)-47, was found in detectable concentrations even in zooplankton, the lowest trophic level examined in this study. most of the ...200616986806
differences in lens optical plasticity in two gadoid fishes meeting in the arctic.arctic and boreal/temperate species are likely to be evolutionary adapted to different light regimes. currently, the boreal/temperate atlantic cod (gadus morhua) is coexisting with the native polar cod (boreogadus saida) in the arctic waters around svalbard, norway. here, we studied light/dark adaptative optical plasticity of their eye lenses by exposing fish to bright light during the polar night. schlieren photography, high-definition laser scanning and ray tracing were used to determine the o ...201425240636
