Previous double team experiments testing line transect methodology for harbor porpoise indicated that a relatively small proportion of the sightings were actually seen by both teams. Results of an additional…
Blood chemistry values were measured from 31 harbor porpoises (Phocoena phocoena) released from herring weirs in the Bay of Fundy, Canada. Sodium, phosphorus, calcium, chloride, magnesium, total protein, albumin, globulin,…
Parasite and pollutant loads, reproductive status and overall condition were recorded for seven harbour porpoise shot at the Faroes in 1987-1988. Four species of nematodes were found. A mixed infection…
Portions of the cytochrome b gene and control region of the mitochondrial DNA molecule were sequenced to investigate systematic relationships among the six extant species of true porpoises, (Cetacea: Phocoenidae).…
(...) Harbor porpoise, Phocoena phocoena, have been caught incidentally in set gill nets off the central California coast since at least 1958 (Norris and Prescott, 1961). The annual mortality of…
This paper presents information on the distribution of harbour porpoise in Norwegian coastal and adjacent waters based on incidental sightings during the period 1964-1968, bycatches in the driftnet salmon fishery…
Published data on concentrations of organochlorine compounds and heavy metals in tissues of harbour porpoises from the eastern North Atlantic are reviewed. The dynamics of pollutants in this population are…
Dolphins and porpoises spend the majority of their lives underwater, out of the view of human observers. Consequently, scientists have relied on indirect means to study the foraging ecology of…
This paper examines trends in abundance and distribution of harbour porpoises in Swedish waters. Returns from questionnaires suggested a decline in number of sightings per year in all areas around…
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…
