Information on the movement of cetaceans in relation to survey vessels is important for determining if abundance and density estimates from ship-based line transect sighting surveys are biased. A ship-based…
We estimated the potential intrinsic rate of increase (r) of the harbour porpoise (Phocoena phocoena) population in the Bay of Fundy and Gulf of Maine using empirical data on reproductive…
Total Hg levels were determined in 17 harbour porpoises Phocoena phocoena collected in the North Sea and the Kattegat (muscle, liver and kidney), as well as in a sperm whale…
Aerial surveys covering 5117 linear kilometers were conducted at 91 and 183 m altitude under optimal sighting conditions in an area north of Fyn, Denmark, and in the Bay of…
Harbour Porpoises Phocoena phocoena were counted along a 270-km-long transect around southwestern Ireland on 17 July 1989, a day with exceptionally favourable weather conditions. A total of 251 porpoises were…
(...) The harbor porpoise (Phocoena phocoena) is found in coastal temperate and subarctic waters of the Northern Hemisphere (Gaskin et al. 1974). Although the species’ biology has been well documented…
Structural modifications of the odontocete skull and nasal passages have shifted the position of the facial bones and associated soft anatomy to the dorsal aspect of the head. The facial…
We compared the contents of 31 stomachs of harbour porpoise calves killed in commercial gill nets in the Bay of Fundy between July and September, 1985–1991, with the stomach contents…
Eighty-one dead cetaceans of a variety of species and from British waters were examined for evidence of skin disease and 69% were found to be affected. The most common conditions…
The available information on the status of populations of three species of dolphins in the Black Sea is reviewed. These populations were subject to a commercial fishery from 1870 to…
