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…
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…

Veterinary Record (2001)
Sera from 58 odontocetes taken in fisheries off Peru in 1993 to 1995 and from 24-cetaceans stranded along the Spanish coast of the Mediterranean in 1997 to 1999 were tested…
Geographical variation of the parasite, Phyllobothrium delphini (Cestoda), in Dall’s porpoise, Phocoenoides dalli, in the northern north Pacific, Bering Sea, and Sea of Okhotsk
Walker, William A.
Marine Mammal Sci (2001)
Prevalence of the larval cestode, Phyllobothrium delphini, was estimated from 2,445 Dall's porpoise, Phocoenoides dalli, from the incidental take of the Japanese high seas salmon drift-net fishery in the northwestern…
Trends in the maternal investment of harbour porpoises are uncoupled from the dynamics of their primary prey
Read, A. J.
Proceedings of the Royal Society B: Biological Sciences (2001)
Harbour porpoises in the Bay of Fundy and Gulf of Maine feed primarily on Atlantic herring. Herring stocks have undergone dramatic fluctuations in abundance over the past three decades due…

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…
The enigma of harbor porpoise presence in the Mediterranean Sea
Frantzis, Alexandros; Gordon, Jonathan; Hassidis, Gilda; Komnenou, Anastasia
Marine Mammal Sci (2001)
(...) Harbor porpoises are assumed to have colonized the Black Sea from the Atlantic Ocean (Gaskin 1982, Rosel 1997). This hypothesized relationship is based on both geographical proximity and genetic…
Abundance of harbour porpoise and other cetaceans in the North Sea and adjacent waters
Hammond, P.S.; Berggren, P.; Benke, H.; Borchers, D.L.; Collet, A.; Heide-Jørgensen, M.P.; Heimlich, S.; Hiby, A.R.; Leopold, M.F.; Øien, N.
Journal of Applied Ecology (2002)
1. The status of small cetaceans in the North Sea and adjacent waters has been of concern for many years. Shipboard and aerial line transect surveys were conducted to provide…
Population structure of finless porpoises (Neophocaena phocaenoides) in coastal waters of Japan
Yoshida, H.
The Raffles Bulletin of Zoology (2002)
To clarify population structure of finless porpoises (Neophocaena phocaenoides) in Japan, a sequence of studies have been conducted: a questionnaire survey and aerial sighting surveys to obtain information on porpoise…
