Scientific Reports of the Whales Research Institute (1978)
The geographical variation of the colour types of the species indicates three local stocks in the northwestern North Pacific and western Bering Sea (WNP/BS), off the Pacific coast of Japan…
Chromosome number of two color types of the Dall’s porpoise
Yabu, H.; Ogi, H.
Scientific Reports of the Whales Research Institute (1986)
(...) Makino (1948) studied chromosomes of a male P. dalli using traditional sectioning of testis tissue. Since it was generally accepted in those days that the two color morphs represent…
Genetic variability and differentiation in the toothed whales
Shimura, E.; Numachi, K.-I.
Scientific Reports of the Whales Research Institute (1987)
Genetic variability and differentiation of three families containing 12 species of toothed whales mainly from the sea around Japan have been examined by starch-gel electrophoresis at 19 genetic loci encoding…
Phylogenetic relationships among the true porpoises (Cetacea: Phocoenidae)
Rosel, P; Haygood, M; Perrin, W
Molecular Phylogenetics and Evolution (1995)
Portions of the cytochrome b gene and control region of the mitochondrial DNA molecule were sequenced to investigate systematic relationships among the six extant species of true porpoises, (Cetacea: Phocoenidae).…
Harbour porpoises in the north Atlantic: edited extract from the Report of the IWC Scientific Committee, Dublin 1995
Donovan, G.P.; Bjorge, A.
Report of the International Whaling Commission (1995)
At the meeting of the IWC Scientific Committee held in Dublin in May 1995, the special topic addressed by the sub-committee on small cetaceans was the North Atlantic harbour porpoise.…
The phylogeographic pattern of mitochondrial DNA variation in the Dall’s porpoise Phocoenoides dalli
MCMILLAN, W. O.; BERMINGHAM, E.
Molecular Ecology (1996)
We used 11 restriction endonucleases to study mtDNA variation in 101 Dall's porpoises Phocoenoides dalli from the Bering Sea and western North Pacific. There was little phylogeographic patterning among the…
Population structure of harbour porpoises Phocoena phocoena in the seas around the UK and adjacent waters
Walton, M. J.
Proceedings of the Royal Society B: Biological Sciences (1997)
The population structure of harbour porpoises from British and adjacent waters was studied by examining variability in a 200 bp (base pair) section of the control region of mitochondrial DNA…
An intergeneric hybrid in the family Phocoenidae
Baird, Robin W.; Willis, Pamela M.; Guenther, Tamara J.; Wilson, Paul J.; White, Bradley N.
Canadian Journal of Zoology (1998)
A 60-cm female fetus recovered from a Dall's porpoise (Phocoenoides dalli) found dead in southern British Columbia was fathered by a harbour porpoise (Phocoena phocoena). This is the first report…
Examining the risk of inbreeding depression in a naturally rare cetacean, the vaquita (Phocoena sinus)
Taylor, Barbara L.; Rojas-Bracho, Lorenzo
Marine Mammal Sci (1999)
Uncertainty about the magnitude of various risks facing endangered species can paralyze conservation action. The vaquita is a naturally rare porpoise that has declined to the low hundreds of individuals…
Mitochondrial DNA variation in the critically endangered vaquita Phocoena sinus Norris and MacFarland, 1958
Rosel, Patricia E.; Rojas-Bracho, Lorenzo
Marine Mammal Sci (1999)
The vaquita, Phocoena sinus, is one of two critically endangered cetacean species, and is listed as an endangered species in both the United States and Mexico. These listings result from…
