Report of the International Whaling Commission (1996)
This paper summarises current knowledge of the three populations of harbour porpoises in US and Canadian Atlantic waters. During the summer, the populations are centred in the Gulf of Maine/Bay…
Geographical variation in metric skull characters among proposed subpopulations and stocks of harbor porpoise, Phocoena phocoena, in the western north Atlantic
Gao, Anli; Gaskin, D. E.
Marine Mammal Science (1996)
A total of 433 skulls of harbor porpoises, Phocoena phocoena, were examined to evaluate geographical variation within the western North Atlantic, using analysis of covariance and discriminant analysis based on…
Life history of the vaquita, Phocoena sinus (Phocoenidae, Cetacea)
Hohn, A. A.; Read, A. J.; Fernandez, S.; Vidal, O.; Findley, L. T.
Journal of Zoology (1996)
The vaquita, Phocoena sinus, is the most endangered marine cetacean primarily due to incidental mortality in fishing nets. We examined a sample of 56 vaquitas to study the life history…
Summer feeding habits of Dall’s porpoise, Phocoenoides dalli, in the southern Sea of Okhotsk
Walker, William A.
Marine Mammal Sci (1996)
Stomach contents were analyzed from 85 Dall's porpoises, Phocoenoides dalli, taken in the southern Sea of Okhotsk during the summer of 1988. Thirteen species of fish and five species of…
Violent interactions between bottlenose dolphins and harbour porpoises
Ross, H. M.; Wilson, B.
Proceedings of the Royal Society B: Biological Sciences (1996)
The majority (63%) of harbour porpoises stranded around the Moray Firth, Scotland, died from trauma characterized by multiple skeletal fractures and damaged internal organs. Surface injuries consisted of skin cuts…
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…
Levels of organochlorine compounds, including PCDDS and PCDFS, in the blubber of cetaceans from the west coast of North America
Jarman, W. M.; Norstrom, R. J.; Muir, D. C. G.; Rosenberg, B.; Simon, M.; Baird, R. W.
Marine Pollution Bulletin (1996)
Levels of organochlorine compounds (PCDD, PCDF, PCB and organochlorine pesticides) were determined in cetaceans collected from the west coast of North America between 1986 and 1989. The samples included gray…
Effects of Beaufort sea state on the sightability of harbor porpoises in the Gulf of Maine
Palka, D.
Report of the International Whaling Commission (1996)
Effects of Beaufort sea state heterogeneities on density estimates of harbor porpoises from data collected during 'independent' team line transect sighting surveys are investigated. The surveys were conducted in the…
Trends in abundance of the Gulf of Maine population of harbour porpoise
Olson, P. A.
Master's Thesis - University of Rhode Island (1996)
Hundreds of harbor porpoise die each year as bycatch in the Gulf of Maine's sink gillnet fishery. In recent years, concern has arisen whether the Gulf of Maine population of…
Investigations on cetacean sonar XI: Intrinsic comparison of the wave shapes of some members of the Phocoenidae family
Kamminga, C.; Cohen Stuart, A.; Silber, G. K.
Aquatic Mammals (1996)
A comparison of the acoustic waveforms of three different species, Phocoena phocoena, Phocoena sinus and Neophocaena phocaenoides of the sub-family Phocoeninae is made with the species Phocoenoides dalli of the…
