Distribution Studies

Counts of species of foraminifera from 75 samples of sediment from East Bay, MacKeazie King Island, in the Canadian Arctic were converted to a matrix of presence–absence data (56 species × 75 stations). These were submitted to both normal and inverse association–analysis as a preliminary test of the application of that multivariate method to problems in marine ecology. The results are compared with observations made at the time the survey was carried out. Although the pattern of sampling was not the most suitable for association–analysis, the results indicate that the method may prove quite informative.

Common Eiders

Contamination of the Arctic environment by persistent organic pollutants (POPs) and trace elements remains a key concern for local residents as well as wildlife and resource management organizations. The common eider (Somateria mollissima) is a large marine duck that forms an important component of the diet of many Arctic predators, including humans. Although various studies have been carried out to evaluate the role of a few contaminants thought to be of local concern, efforts to assess contaminant residues in eider tissues have not been comprehensive. In this review, we summarize the available information on POPs and trace elements in common eiders across the Canadian Arctic. With the exception of one adult bird collected near Qikiqtarjuaq, Nunavut, eiders had detectable but low concentrations of most POPs, in some cases markedly lower than European eiders, and in all cases far lower than POP levels found in sympatric marine birds. However, common eiders did have elevated concentrations of many trace elements, noticeably cadmium, selenium, and copper, but these were below levels associated with toxicological risk to marine birds. Although the collective evidence suggests that common eiders of the Canadian Arctic may carry elevated levels of some contaminants, there was no evidence that these levels posed a threat to wildlife health. Key words: common Eider, persistent organic pollutants, trace elements, Arctic Canada.

Ice Conditions

The southwestern part of Foxe Basin is a little known region of the Canadian Arctic, being difficult to access during the summer because of heavy and unpredictable ice conditions. Surveys of birds and marine mammals in the area were carried out by lightweight expeditions in the summers of 1994 and 1995, using sea-kayaks, as well as a Peterhead boat from the nearest community, at Repulse Bay. The area supports important populations of narwhal, bowhead whales and walrus, as well as significant concentrations of shorebirds, common eiders, black guillemots, and perhaps one third of the world's Thayer's gulls. New information was obtained on the status and abundance of these species and novel observations were made on the feeding ecology and breeding phenology of the gulls.
