Low mitochondrial diversity and small effective population sizes of the copepods Calanus finmarchicus and Nannocalanus minor: possible impact of climatic variation during recent glaciation.

Abstract excerpt

Molecular population genetic diversity of two planktonic copepods of the North Atlantic, Calanus finmarchicus and Nannocalanus minor (Crustacea, Copepoda, Calanoida), was characterized using the sequence variation in a 350 bp region of the mitochondrial 16S rRNA gene. The subarctic species, C. finmarchicus, shows lower population genetic diversity (haplotype diversity, h = 0.368, SD = 0.043; nucleotide diversity,...
