Yang, Guang; Liu, Shan; Ren, Wenhua; Zhou, Kaiya; Wei, Fuwen
Acta Theriologica (2003)
Baiji Lipotes vexillifer (Miller, 1918) and the Yangtze finless porpoise Neophocaena phocaenoides asiaeorientalis (Pilleri and Gihr, 1972) are two sympatric small cetaceans inhabiting the middle and lower reaches of the…
The harbour porpoise (Phocoena phocoena) in the North Atlantic: Variability in habitat use, trophic ecology and contaminant exposure
Bjørge, Arne
NAMMCOSP (2003)
Harbour porpoises inhabit coastal waters, in habitats that are characterized by high diversity and complexity in terms of their bathymetry, substrate, fish communities and point sources of contaminants. The complexity…
Feeding habits of Dall’s porpoises (Phocoenoides dalli) in the subarctic North Pacific and the Bering Sea basin and the impact of predation on mesopelagic micronekton
Ohizumi, Hiroshi; Kuramochi, Toshiaki; Kubodera, Tsunemi; Yoshioka, Motoi; Miyazaki, Nobuyuki
Deep Sea Research Part I: Oceanographic Research Papers (2003)
We investigated the stomach contents of Dall's porpoises collected in pelagic waters spanning most of their range in the North Pacific and the Bering Sea. Analysis revealed the porpoises fed…
An experimental study of postmortem ocular fluid and core temperature analysis in incidentally captured harbour porpoise (Phocoena phocoena)
Hood, C; Daoust, P-Y; Lien, J; Richter, C
NAMMCOSP (2003)
Determination of elapsed time since death in small cetaceans can be important to our understanding of the nature of their interactions with fishing operations. This pilot study was conducted to…
Influence of sea state on density estimates of harbour porpoises (Phocoena phocoena)
Teilmann, J.
Journal of Cetacean Research and Management (2003)
A ship-based line transect survey was conducted in the Great Belt, Denmark, from 7-20 April 1994, covering an area of 705 linear kilometres. A total of 497 sightings were collected…
