Honour's Thesis - University of London (2004)
Throughout its range, the distribution of the harbour porpoise (Phocoena phocoena L.) has contracted significantly in the last century, particularly in the North Sea. Reasons for this decline have been…
Variability in the diet of harbor porpoises (Phocoena phocoena) in Scottish waters 1992–2003
Santos, M. B.; Pierce, G. J.; Learmonth, J. A.; Reid, R. J.; Ross, H. M.; Patterson, I. A. P.; Reid, D. G.; Beare, D.
Marine Mammal Sci (2004)
Interannual, seasonal, and regional variation in the diet of porpoises, Phocoena phocoena, in Scottish (UK) waters was studied using stomach contents of animals stranded between 1992 and 2003. Most samples…
Echolocation behavior of harbor porpoises Phocoena phocoena around chemically enhanced gill nets
Cox, T. M.; Read, A. J.
Marine Ecology Progress Series (2004)
The echolocation behavior of harbor porpoises Phocoena phocoena around gillnets was monitored to test their response to chemically (BaSO4) enhanced gill nets, designed to be more acoustically reflective than commercial…
Co-variation in the probabilities of sighting harbor porpoises and bottlenose dolphins
Thompson, Paul; White, Sam; Dickson, Ellie
Marine Mammal Sci (2004)
(...) In this study we used data collected from commercial dolphin-watching trips to determine whether there was any relationship between the probabilities of sighting bottlenose dolphins and harbor porpoises. Surveys…
Review of small cetaceans: Distribution, behaviour, migration and threats
Culik, Boris
(2004)
This report summarises the available knowledge on odontocete (toothed whale) distribution, behaviour, migration and threats and was compiled for the Bonn Secretariat of CMS.
Seasonal abundance, distribution, and prey species of harbour porpoise (Phocoena phocoena) in southern Vancouver island waters
Hall, A.
Master's Thesis - University of British Columbia (2004)
Harbour porpoise (Phocoena phocoena) occur year round in the waters of southern British Columbia, but little is known about their seasonal abundance, habitat use and food habits. A systematic vessel-based…
Natural hybridization between Dall’s porpoises (Phocoenoides dalli) and harbour porpoises (Phocoena phocoena)
Willis, Pamela M; Crespi, Bernard J; Dill, Lawrence M; Baird, Robin W; Hanson, M Bradley
Can. J. Zool. (2004)
Natural hybridization occurs rarely in mammals compared with other taxonomic groups of animals. Cetaceans appear unique among mammals in exhibiting striking karyological uniformity, which suggests that they have the potential…
Entrapment of harbour porpoises (Phocoena phocoena) in herring weirs in the Bay of Fundy, Canada
Neimanis, A. S.; Koopman, H. N.; Westgate, A. J.; Murison, L. D.; Read, A. J.
Journal of Cetacean Research and Management (2004)
Harbour porpoises (Phocoena phocoena) are small coastal cetaceans vulnerable to mortality in fishing operations. Not all interactions are fatal, however, and each year many porpoises swim into and are subsequently…
Organochlorine residues in harbour porpoises from Southwest Greenland
Borrell, Asunción; Aguilar, Alex; Cantos, Gemma; Lockyer, Christina; Heide-Jørgensen, Mads Peter; Jensen, Jette
Environmental Pollution (2004)
During the 1995 hunting season, 75 harbour porpoises (Phocoena phocoena) were sampled in three locations in West Greenland: Maniitsoq, Nuuk, and Paamiut. Sex, age, morphometrics, reproductive condition, and organochlorine compound…
An experimental study of postmortem ocular fluid and core temperature analysis in incidentally captured harbour porpoise (Phocoena phocoena)
Hood, C; Daoust, P-Y; Lien, J; Richter, C
NAMMCOSP (2003)
Determination of elapsed time since death in small cetaceans can be important to our understanding of the nature of their interactions with fishing operations. This pilot study was conducted to…
