Report of the International Whaling Commission (1984)
The population biology of most phocoenid species is still rather poorly understood. It is important that we improve our knowledge in view of concerns which have been expressed in recent…
Dall porpoise, Phocoenoides dalli (True): Observations in captivity and at sea
Ridgway, S.H.
Norsk Hvalfangst-Tidende (1966)
The Dall porpoise Phocoenoides dalli is common in south central California waters from October through June. During the summer months it is not commonly found farther south than about 35°.…
The relationship between heart mass and body mass for three cetacean genera: Narrow allometry demonstrates interspecific differences
Ridgway, Sam H.; Kohin, Suzanne
Marine Mammal Sci (1995)
(...) Brody (1945) fitted an allometric equation to heart mass (kg) as a function of body mass (kg) for adult mammals ranging in body size from 0.01 to over 100,000…
A global review of porpoise (Cetacea: Phocoenidae) mortality in gillnets
Jefferson, Thomas A.; Curry, Barbara E.
Biological Conservation (1994)
A global review of mortality of porpoises in gillnet fisheries indicates that individuals of all six species become entangled and die in gillnets. Harbor porpoises Phocoena phocoena are taken throughout…
Blood oxygen and ecology of porpoises of three genera
Ridgway, S.H.; Johnston, D.G.
Science (1966)
Blood volumes, hemoglobin concentrations, packed-cell volumes, and heart weights were determined in three genera of porpoises which differ from one another in behavior and ecology. The estimate for the total…
A note on cephalopods from the stomachs of Dall’s porpoises (Phocoenoides dalli) from the Northwestern Pacific and Bering Sea, 1978-1982
Fiscus, C. H.; Jones, L. L.
Journal of Cetacean Research and Management (1999)
Cephalopod prey were identified from the stomachs of 100 Dall's porpoise (Phocoenoides dalli) incidentally taken by commercial salmon gillnets and research vessels from 1978 to 1982 in the western North…
A note on radionuclide 137Cs and 40K concentrations in Dall’s porpoises, Phocoenoides dalli, in coastal waters of Japan
Kasamatsu, F.; Kawabe, K.; Inatomi, N.; Murayama, T.;
Journal of Cetacean Research and Management (1999)
Concentrations of artificial radionuclide 137Cs and natural radionuclide 40K in Dall's porpoise, Phocoenoides dalli, from the Pacific coast of northern Japan in 1996 are presented. Concentrations of 137Cs in muscle…
Distribution and abundance of marine mammals in the coastal waters of British Columbia, Canada
Williams, R.; Thomas, L.
Journal of Cetacean Research and Management (2007)
Information on animal distribution and abundance is integral to wildlife conservation and management. However abundance estimates have not been available for many cetacean species inhabiting the coastal waters of Canada’s…
Updated marine mammal distribution and abundance estimates in British Columbia
Best, B. D.; Fox, C. H.; Williams, R.; Halpin, P. N.; Paquet, P. C.
Journal of Cetacean Research and Management (2015)
Information relating to the distribution and abundance of species is critical for effective conservation and management. For many species, including cetacean species of conservation concern, abundance estimates are lacking, out…
Comments on the Delphinoidea
Fraser, F. C.
Whales, Dolphins, and Porpoises [Proceedings] (1966)
(...) Flower (1883), in his search for the trenchant characters he needed to reach a decision about the arrangement of the Delphinidae, saw that the configuration of the pterygoid bones…
