Helminth parasites of the digestive tract of the harbour porpoise Phocoena phocoena in Danish waters: A comparative geographical analysis
Herreras, MV; Kaarstad, SE; Balbuena, JA; Kinze, CC; Raga, JA
Diseases of Aquatic Organisms (1997)
Most studies of the helminth fauna of the harbour porpoise Phocoena phocoena have focused on taxonomy, associated pathologies and surveys reporting prevalence and abundance of the parasite species. This study…
Population structure of harbour porpoises Phocoena phocoena in the seas around the UK and adjacent waters
Walton, M. J.
Proceedings of the Royal Society B: Biological Sciences (1997)
The population structure of harbour porpoises from British and adjacent waters was studied by examining variability in a 200 bp (base pair) section of the control region of mitochondrial DNA…

Baird, Robin W.; Willis, Pamela M.; Guenther, Tamara J.; Wilson, Paul J.; White, Bradley N.
Canadian Journal of Zoology (1998)
A 60-cm female fetus recovered from a Dall's porpoise (Phocoenoides dalli) found dead in southern British Columbia was fathered by a harbour porpoise (Phocoena phocoena). This is the first report…
An interaction between Pacific white-sided dolphins and a neonatal harbor porpoise
Baird, R. W.
Mammalia (1998)
(...) Inter-specific behavioral interactions in the order Cetacea are diverse and often complex, including predation (e.g. Jefferson el al. 1991), "harassment" (Shane 1995 ; Shelden et al. 1995; Palacios and…
Evidence for infanticide in bottlenose dolphins: an explanation for violent interactions with harbour porpoises?
Patterson, I. A. P.; Reid, R. J.; Wilson, B.; Grellier, K.; Ross, H. M.; Thompson, P. M.
Proceedings of the Royal Society B: Biological Sciences (1998)
Most harbour porpoises found dead on the north–east coast of Scotland show signs of attack by sympatric bottlenose dolphins, but the reason(s) for these violent interactions remains unclear. Post–mortem examinations…
Serological evidence of morbillivirus infection in small cetaceans from the Southeast Pacific
Van Bressem, Marie-Françoise; Van Waerebeek, Koen; Fleming, Martin; Barrett, Thomas
Veterinary Microbiology (1998)
The presence of morbillivirus-specific serum antibodies was examined by an indirect enzyme linked immunosorbent assay (iELISA) and virus neutralization tests in serum samples from 30 dusky dolphins (Lagenorhynchus obscurus), 8…

Monitoring a rehabilitated harbor porpoise using satellite telemetry
Westgate, Andrew J.; Read, Andrew J.; Cox, Tara M.; Schofield, T. David; Whitaker, Brent R.; Anderson, Kurt E.
Marine Mammal Sci (1998)
(...) Each year between February and May, immature harbor porpoises (Phocoena phocoena) strand along the mid-Atlantic coast of the United States (Haley and Read 1993). Occasionally, harbor porpoises strand alive,…
