Serious concerns have been raised regarding the status of the harbour porpoise populations in the North Atlantic and specifically for those inhabiting Atlantic Canadian waters. In 1991 harbour porpoise in…
Population structure of finless porpoise (Neophocaena phocaenoides) in coastal waters of Japan based on mitochondrial DNA sequences
Yoshida, H.; Yoshioka, M.; Shirakihara, M.; Chow, S
Journal of Mammalogy (2001)
To clarify population structure of finless porpoises (Neophocaena phocaenoides) in Japan, we examined mitochondrial DNA sequences of 174 animals. All individuals except for a female were collected in 5 geographically…
Age, length and reproductive parameters of harbour porpoises Phocoena phocoena (L.) from West Greenland
Lockyer, C.; Heide-Jørgensen, M. P.; Jensen, J.; Kinze, C. C.; Buus Sørensen, T.
ICES Journal of Marine Science (2001)
During 1988, 1989 and 1995, 187 harbour porpoises (Phocoena phocoena) were sampled from the catches off West Greenland during the months of July, August and September. The samples were taken…
Harbor porpoise (Phocoena phocoena) abundance in Alaska: Bristol Bay to southeast Alaska, 1991-1993
Dahlheim, M.; York, A.; Towell, R.; Waite, J.; Breiwick, J.
Marine Mammal Sci (2000)
Between 1991 and 1993, Alaska harbor porpoise (Phocoena phocoena) abundance was investigated during aerial surveys throughout much of the coastal and offshore waters from Bristol Bay in the eastern Bering…
A preliminary study on the variability of the mitochondrial DNA control region in populations of finless porpoises (Neophocaena phocaenoides) in Chinese waters
Yang, Guang; Zhou, Kaiya
Biology and Conservation of Freshwater Cetaceans in Asia (2000)
The mitochondrial DNA control region of 12 finless porpoises (Neophocaena phocaenoides) from the Yangtze River, Yellow Sea, and South China Sea, was amplified. Two portions, 317 and 245 base pairs,…
Phylogeography, intraspecific structure and sex-biased dispersal of Dall’s porpoise, Phocoenoides dalli , revealed by mitochondrial and microsatellite DNA analyses
Escorza-Treviño, S.; Dizon, A. E.
Molecular Ecology (2000)
Mitochondrial DNA (mtDNA) control-region sequences and microsatellite loci length polymorphisms were used to estimate phylogeographical patterns (historical patterns underlying contemporary distribution), intraspecific population structure and gender-biased dispersal of Phocoenoides dalli…
Application of a new method to investigate population structure in the harbour porpoise, Phocoena phocoena, with special reference to the North and Baltic Seas
Lockyer, C.
Journal of Cetacean Research and Management (1999)
Tooth ultrastructure in harbour porpoise is examined as a possible tool for differentiating between animals from different geographical regions in the North Atlantic. Nine different characteristics in both dentine and…
Geographical differences in organochlorine contaminants in harbour porpoises Phocoena phocoena from the western North Atlantic
Westgate, A.J.; Tolley, K.A.
Marine Ecology Progress Series (1999)
Organochlorine contaminants, including polychlorinated biphenyls (PCBs), chlorinated bornanes (CHBs), dichloro-diphenyl-trichloroethanes (DDTs), chlordanes (CHLORs), hexachlorocyclohexanes (HCHs) and, chlorobenzenes (CBZs) were quantified in 188 harbour porpoises (Phocoena phocoena) killed in commercial fisheries…
Genetic population structure of harbour porpoises (Phocoena phocoena) in the North Sea and Norwegian waters
Tolley, K. A.; Rosel, P. E.; Walton, M.; Bjorge, A.; Oien, N.
Journal of Cetacean Research and Management (1999)
The harbour porpoise (Phocoena phocoena) is subject to a high rate of incidental mortality in fisheries worldwide and, in some areas, these rates are sufficiently high to warrant concern over…
Assessing the population structure of the harbor porpoise (Phocoena phocoena) by discriminant analysis
Tolley, Krystal A.
Marine Mammal Sci (1998)
(...) Gaskin (1984, 1992) suggested that harbor porpoises in the northwestern Atlantic are partitioned into three subpopulations: Bay of Fundy/Gulf of Maine, Eastern Newfoundland, and Gulf of St. Lawrence (see…
