Veterinary Record (2001)
Sera from 58 odontocetes taken in fisheries off Peru in 1993 to 1995 and from 24-cetaceans stranded along the Spanish coast of the Mediterranean in 1997 to 1999 were tested…
Trends in the maternal investment of harbour porpoises are uncoupled from the dynamics of their primary prey
Read, A. J.
Proceedings of the Royal Society B: Biological Sciences (2001)
Harbour porpoises in the Bay of Fundy and Gulf of Maine feed primarily on Atlantic herring. Herring stocks have undergone dramatic fluctuations in abundance over the past three decades due…
Geographical variation of the parasite, Phyllobothrium delphini (Cestoda), in Dall’s porpoise, Phocoenoides dalli, in the northern north Pacific, Bering Sea, and Sea of Okhotsk
Walker, William A.
Marine Mammal Sci (2001)
Prevalence of the larval cestode, Phyllobothrium delphini, was estimated from 2,445 Dall's porpoise, Phocoenoides dalli, from the incidental take of the Japanese high seas salmon drift-net fishery in the northwestern…

The enigma of harbor porpoise presence in the Mediterranean Sea
Frantzis, Alexandros; Gordon, Jonathan; Hassidis, Gilda; Komnenou, Anastasia
Marine Mammal Sci (2001)
(...) Harbor porpoises are assumed to have colonized the Black Sea from the Atlantic Ocean (Gaskin 1982, Rosel 1997). This hypothesized relationship is based on both geographical proximity and genetic…
First records of the spectacled porpoise Phocoena dioptrica in continental Australian waters
Evans, Karen; Kemper, Catherine; Hill, Mark
Marine Mammal Sci (2001)
(...) The spectacled porpoise, Phocoena dioptrica (Lahille, 1912), is a little-known species found in cool temperate, sub- and low-antarctic waters of the Southern Hemisphere (Jefferson et al. 1993, Goodall and…
Reactions of harbor porpoises Phocoena phocoena and herring Clupea harengus to acoustic alarms
Culik, B.M.; Koschinski, S.; Tregenza, N.; Ellis, G.M.
Marine Ecology Progress Series (2001)
Small cetaceans are susceptible to incidental mortality in the various forms of gillnet fisheries throughout their range. Research conducted since 1994 has shown that acoustic alarms (pingers) emitting high-frequency pulsed…
Radio tracking finless porpoises (Neophocaena phocaenoides): Preliminary evaluation of a potential technique, with cautions
Würsig, B.; Wang, D.; Zhang, X.
Biology and Conservation of Freshwater Cetaceans in Asia (2000)
Three finless porpoises (Neophocaena phocaenoides) from the Yangtze River were fitted with cotton cloth vests and small radio transmitters. They were tracked for 2.6, 11.0, and 14.6 days in the…
Re-evaluation of geographic variation in the white flank patch of dalli-type Dall’s porpoises
Amano, Masao; Marui, Miho; Guenther, Tamara; Ohizumi, Hiroshi; Miyazaki, Nobuyuki
Marine Mammal Sci (2000)
(...) Amano and Miyazaki (1996) found a geographic difference in the size of the white flank patch among dalli-type animals and reported that porpoises from the Sea of Japan-Okhotsk population…

Perrin, William F.; Goodall, R. Natalie P.; Cozzuol, Mario A.
Journal of Cetacean Research and Management (2000)
Cranial and post-cranial variation is described for a large series of specimens of spectacled porpoise from Argentina and compared with that for specimens from other areas of the Southern Hemisphere.…
