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…

NAKAMURA, Koji; YAMADA, Tadasu K.; SHIMAZAKI, Kenji
Mammal Study (1998)
(...) The physical properties of the sounds produced by toothed whales are directly affected by the morphological characteristics of the air space in the head and by the sound-production mechanism…
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,…
Organochlorines in Indo-Pacific hump-backed dolphins (Sousa chinensis) and finless porpoises (Neophocaena phocaenoides) from Hong Kong
Parsons, E. C. M.; Chan, H. M.
The Marine Biology of the South China Sea (1998)
Blubber samples from eight Indo-Pacific hump-backed dolphins (Sousa chinensis) and eleven finless porpoises (Neophocaena phocaenoides) stranded between 1993 and 1996, in Hong Kong waters, were collected for organochlorine analysis. Levels…
Assessing the population structure of the harbor porpoise (Phocoena phocoena) by discriminant analysis
Tolley, Krystal A.
Marine Mammal Sci (1998)
(...) Gaskin (1984, 1992) suggested that harbor porpoises in the northwestern Atlantic are partitioned into three subpopulations: Bay of Fundy/Gulf of Maine, Eastern Newfoundland, and Gulf of St. Lawrence (see…
Documenting the bycatch of harbor porpoises, Phocoena phocoena, in coastal gillnet fisheries from stranded carcasses
Cox, T. M.; Read, A. J.; Barco, S.; Evans, J.; Gannon, D. P.; Koopman, H. N.; McLellan, W. A.; Murray, K.; Nicolas, J.; Pabst, D. A.; Potter, C. W.; Swingle, W. M.; Thayer, V. G.; Touhey, K. M.; Westgate, A. J.
Fishery Bulletin (1998)
We examined 107 harbor porpoise (Phocoena phocoena) carcasses recovered from beaches in Maryland, Virginia, and North Carolina between 1994 and 1996 for evidence of entanglement in fishing gear. Stranded porpoises…
Geographical variation of the harbor porpoise, Phocoena phocoena, evaluated by discriminant analysis
Gao, Anli; Gaskin, D. E.
Marine Mammal Sci (1998)
(...) In the preceding communication K. A. Tolley states (twice) that Gao and Gaskin (1996) committed “serious interpretive errors that neither support their results nor the recent literature.” Needless to…
