In order to monitor the diving behavior of free-ranging cetaceans, microdataloggers, with pre-programmed release mechanisms, were attached to the dorsal fins of two female harbor porpoises (Phocoena phocoena) in Funka…

This study presents a detailed seasonal comparison of the abundance and distribution of cetaceans within 100-150 nmi (185-278 km) of the California coast during 1991 and 1992. The results of…
(page 121) (...) Miller (1925) and Kellogg (1928) included the true porpoises in the family Delphinidae and did not even grant them subfamily status. However, Slijper (1936) and Fraser and…
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…
(...) 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…
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…
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…
(...) 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…
(...) 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,…
A programme to assess the cetacean by-catch in the Irish and UK set gillnet fisheries in the Celtic Sea was conducted from August 1992 to March 1994 using volunteer observers.…
