To understand the interior of British Columbia the reader must realize that the white man's history there is short, for Alex Mackenzie was the first white man to make his way overland to the Bella Coola Valley in 1793. Three years later, on his journey to the Pacific Ocean, he followed the Mackenzie River to Mackenzie Bay on the Beaufert Sea.

St. Helens is one of a group of high volcanic peaks that dominate the Cascade Range between northern California and southern British Columbia, Canada. The distribution is in a band that roughly parallels the coastline of the so-called “Ring of Fire,” a near circular array of volcanoes located on islands, peninsulas and the margins of continents that rim the Pacific Ocean.

The genetic diversity and population structure of harbour seals (Phoca vitulina richardsi) along the coasts of British Columbia and parts of Alaska were investigated using both mitochondrial DNA (mtDNA) and nuclear DNA. A 475-bp fragment of the mitochondrial control region was amplified and sequenced from 128 animals. Sixty variable sites defined 72 mtDNA haplotypes with pairwise nucleotide differences as high as 5%. Fifty-eight haplotypes were represented by a single individual, and shared haplotypes were generally restricted to a small geographic range. Phylogenetic reconstruction revealed two distinct populations comprising (i) southern British Columbia and (ii) northern British Columbia - southeast Alaska. Furthermore, the order of the clades suggests that the Pacific Ocean was colonized at least twice, 670 000 and 380 000 years ago. Haplotypes from the first invasion are restricted to a small number of seals around southern Vancouver Island. Analyses of five polymorphic microsatellite loci showed significant differences between the populations of southern British Columbia and northern British Columbia - Alaska. Migration rates for males based on microsatellite data (3-22 seals/generation) were higher than those obtained for females from mtDNA data (0.3 females/generation). Combining all the DNA data collected to date suggests that there are at least three populations of harbour seals in the Pacific composed of seals from (i) Japan, Russia, Alaska, and northern British Columbia, (ii) southern British Columbia and Puget Sound, Washington, and (iii) the outer coasts of Washington, Oregon, and California. The data do not support the existence of two subspecies of harbour seals in the Pacific Ocean.

First Time

Sixty-six specimens of Sebastodes alutus, the Pacific ocean perch, collected from the coast of Oregon and British Columbia were examined for parasitic copepods. The six species identified are Chondracanthus pinguis Wilson, 1912, Chondracanthus triventricosus sp.nov., Clavella parva Wilson, 1912, Brachiella robusta (Wilson 1912) Kabata, 1970, Colobomatus kyphosus sp.nov., and Sarcotaces arcticus Collett 1874. Colobomatus kyphosus is the second species of the genus to be described from the eastern Pacific and Ch. triventricosus is the second chondracanthid to be found in nasal cavities. Sarcotaces arcticus is reported as a parasite of S. alutus for the first time. Details of the appendages of each new species are described and illustrated.
