Presentation Abstract

British Columbia has the richest kelp flora in the world. This reflects the overlap of two distinct kelp floras—Northern and Southern—within the latitudes of Vancouver Island. Further, the British Columbia kelp flora is divided into Salish Sea and outer coast assemblages. This is thought to be driven by temperature/salinity regimes. The Salish Sea protists are subjected to low summer salinities, resulting from snow runoff, and the outer coasters experience low salinities, resulting winter rains. Incomplete surveys indicate a changing kelp flora, perhaps driven by ocean warming: for example, Egregia, of southern origin seems to be replacing Alaria, a northern species. Kelp productivity drives the near-shore food chains and may have been instrumental in the colonization of the Americas, by means of the Kelp Highway.
