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…

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…

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…

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 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…

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…

Reproduction in the porpoises (Phocoenidae): Implications for management

GASKIN, D. E.; SMITH, G. J. D.; WATSON, A. P.; YASUI, W. Y.; YURICK, D. B.
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…

Trends in abundance of Dall’s porpoise in the western north Pacific, 1979 to 1989

Turnock, B.J.; Buckland, S.T.
Report of the International Whaling Commission (1995)

Two density indices of Dall's porpoise abundance were estimated for the western North Pacific from 1979 to 1989. One index is the density of animals (number of animals per square…

Population abundance of Dall’s porpoise (Phocoenoides dalli) in the western north Pacific Ocean

Turnock, B.J.; Buckland, S.T.; Boucher, G.C.
Report of the International Whaling Commission (1995)

Dall's porpoise in the western North Pacific Ocean suffered incidental mortality from the gillnets of the Japanese high seas salmon fishery until 1987 and mortality from the high seas squid…
