The auditory brainstem response (ABR) response to simulated echolocation clicks was studied in a harbor porpoise, Phocoena phocoena, to determine the relationship between the animal’s perceived echo strength and the…
A study of 37 by-caught harbour porpoises from Icelandic and Norwegian waters showed that most were in good or moderate nutritional condition and none was severely emaciated. Mild infection with…
There are three Neophocaena phocaenoides subspecies recognized in Chinese waters: South China Sea population, N. p. phocaenoides; Yellow Sea population, N. p. sunameri; and Yangtze population, N. p. asiaeorientalis. The…
The incidental catch of harbour porpoises (Phocoena phocoena) in the gillnet fishery of the Estuary and Gulf of St. Lawrence, Canada, was examined using: (1) questionnaires mailed to fishermen inquiring…
The monitoring program on harbour porpoises at Horns Rev Offshore Wind Farm in the Danish North Sea, initiated in 1999, has now come to an end with collection of final…
(...) The study reported here was carried out in 1993-1997 when very few data were available on cetacean poxviruses. On the basis of the brick-shaped morphology of cetacean poxviruses (Van…
Epiphyseal development was investigated on X-rays of flippers from 158 harbour porpoises from Danish waters. Development followed a proximodistal pattern similar to what is known in other cetacean species. Ossification…
Pingers on gill nets can reduce bycatch of harbor porpoises. If harbor porpoises habituate to pingers, the effect may be reduced or lost. Two captive harbor porpoises were exposed to…
We compared the distribution of the digenean Pholeter gastrophilus in the stomach of 27 harbour porpoises, Phocoena phocoena, 27 striped dolphins, Stenella coeruleoalba, 18 bottlenose dolphins, Tursiops truncatus, and 100…
In aquatic ecosystems, competitive interactions are occasionally described. Violent attacks on harbour porpoises by bottlenose dolphins were reported and it was proposed that this behavior could result from competitive interactions…
