Résumé

Nucleotide sequence polymorphism in the mitochondrial genomes of 132 adult lobsters (Jasus edwardsil) collected from widespread locales across southern Australia and from New Zealand (April 1989 to June 1990) was assayed, using six restriction endonucleases, to test the hypothesis of a lack of genetic subdivision in a marine species with a long-lived planktonic larva. The mean amount of mtDNA diversity among the 132 mitochondrial genomes was 0.77%. Phenetic clustering and gene-diversity analyses, as well as pairwise comparison of the genetics of specimens from each, or grouped, locales did not detect the presence of genetic subdivision across approx 4600 km of Southern Ocean habitats. The inability of this study to detect population subdivision does not preclude fortutitous, active or habitat-specific larval settlement from producing and maintaining hidden groupings. If genetic homogeneity is maintained in this species by larval dispersal in ocean currents flowing to the east, then westerly populations may deserve special conservation status.
