Marine Mammal Sci (1996)
The prevalence of ‘tattoo’ skin lesions, characteristic of poxvirus infection, was examined in 339 small cetaceans captured in gillnet fisheries off coastal Peru: 196 Lagenorhynchus obscurus (34.7%, CI 29.0%–41.8%), 54…
Seasonal distribution of harbour porpoises in US Atlantic waters
Northridge, S.
Report of the International Whaling Commission (1996)
The seasonal distribution of harbour porpoises in US Atlantic waters is explored by examining aerial sightings made by the CeTAP survey between 1978 and 1988. Sightings rates were very low…
Status of the harbour porpoise (Phocoena phocoena) in Danish waters
Teilmann, J.; Lowry, N.
Report of the International Whaling Commission (1996)
Harbour porpoises are widely distributed in the seas around Denmark. Total abundance in Danish waters is estimated as approximately 100,000 animals. Population density varies considerably by area. There are probably…
Geographic variation in external morphology of Dall’s porpoise, Phocoenoides dalli
Amano, M.; Miyazaki, N.
Aquatic Mammals (1996)
We examined geographic variation in external measurements of Dall’s porpoises, using 269 sexually mature specimens from throughout their range, excluding coastal waters off North America and the northern Okhotsk Sea.…
Functional morphology and homology in the odontocete nasal complex: Implications for sound generation
Cranford, T. W.; Amundin, M.; Norris, K. S.
Journal of Morphology (1996)
The site and physiologic mechanism(s) responsible for the generation of odontocete biosonar signals have eluded investigators for decades. To address these issues we subjected postmortem toothed whale heads to interrogation…

Rogan, E.; Berrow, S. D.
Report of the International Whaling Commission (1996)
This paper reviews and summarises published and unpublished information on harbour porpoises in Irish waters and presents results of recent research. Harbour porpoises have been recorded from all Irish coasts…
Development and performance of an automated harbour porpoise click detector
Chappell, O.P.; Leaper, R.; Gordon, J.
Report of the International Whaling Commission (1996)
Harbour porpoises (Phocoena phocoena) are notoriously difficult to observe and become very difficult to see in moderate or rough sea conditions. Passive acoustic monitoring provides a complementary study method to…
Harbour porpoises, Phocoena phocoena, in Portuguese waters
Sequeira, M.
Report of the International Whaling Commission (1996)
Biological data on the harbour porpoise in Portuguese coastal waters are scarce, mainly because of the small number of animals available for study. Nevertheless, a regular geographical distribution pattern can…

Report of the International Whaling Commission (1995)
Eight fresh specimens of Burmeister's porpoise caught in gillnets in the Necochea area (Buenos Aires Province) were studied for external morphometrics, age, basic reproductive data, organochlorine pollutant levels and parasites.…
