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…
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 (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 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…
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…
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…
The prevalence of ‘tattoo’ skin lesions, characteristic of poxvirus infection, was examined in 339 small cetaceans captured in gillnet fisheries off coastal Peru: 196 Lagenorhynchus obscurus (34.7%, CI 29.0%–41.8%), 54…
The seasonal distribution of harbour porpoises in US Atlantic waters is explored by examining aerial sightings made by the CeTAP survey between 1978 and 1988. Sightings rates were very low…
Harbour porpoises are widely distributed in the seas around Denmark. Total abundance in Danish waters is estimated as approximately 100,000 animals. Population density varies considerably by area. There are probably…
In this paper we report findings on the diet of the harbour porpoise (Phocoena phocoena) in Danish, Swedish and Norwegian waters. The study is based on stomach contents from 247…
