Sea Otter, <em>Enhydra lutris</em>, Sightings off Haida Gwaii / Queen Charlotte Islands, British Columbia, 1972-2002

An Ecosystem Model of the Ocean Around Haida Gwaii, Northern British Columbia: Ecopath, Ecosim and Ecospace

Ice-free conditions on the queen charlotte islands, british columbia, at the height of late wisconsin glaciation.

New radiocarbon dates and plant macrofossil data establish that parts of the Queen Charlotte Islands, British Columbia, were ice-free during and subsequent to the late Wisconsin glacial maximum on the Pacific coast of Canada. A paleoecological investigation of dated sediments at Cape Ball has indicated that a varied flora consisting of terrestrial and aquatic plants was present there about 16,0...

Post-breeding movements of Ancient Murrelet Synthliboramphus antiquus family groups, subsequent migration of adults and implications for management

Increased shipping in British Columbia (BC) waters poses risks for marine birds from marine oil spills. Ancient Murrelets (Synthliboramphus antiquus), small marine diving birds of which half of the world's population breeds in BC, are especially susceptible to oiling immediately after departing from their breeding colonies, as their offspring are flightless, constraining their parents to remain...

Postglacial population genetic differentiation potentially facilitated by a flexible migratory strategy in Golden-crowned Kinglets (Regulus satrapa)

Relatively recently, temperate regions in North America were covered by extensive ice sheets, making them inhospitable to contemporary flora and fauna. Since the retreat of the ice sheets, these regions have been recolonized by a diversity of taxa, some of which have undergone rapid postglacial divergence. Evidence supports the hypothesis that some taxa persisted in unglaciated refugia during t...

Down's syndrome and maternal age in British Columbia, 1972--75.

The occurrence of Down's syndrome in British Columbia during the period 1972-75 is analyzed with respect to maternal age distribution. This period is compared with previously studied periods. No marked trends are evident in the various age group-specific rates studied. The significance of these findings is discussed in connection with a possible role of environmental nutagens in induction of Do...
