"Calanus glacialis is an ecologically important marine copepod found throughout the Arctic Ocean with limited distributions in the North Pacific and North Atlantic Oceans. We employed molecular techniques to determine the population genetic structuring of C. glacialis across the boundaries of these 3 oceans," scientists in Sidney, Canada report.
"Examination of the DNA sequence of the 16S ribosomal RNA gene identified 2 predominant haplotypes which defined the Arctic and North Pacific (Bering Sea) populations. Advection from the Bering Sea into the Arctic as far as the western Canada Basin was detected, but C. glacialis from the Bering Sea was absent in the ...
