Little is known about the biology or status of the harbour porpoise (Phocoena phocoena) in British Columbia (BC), Canada. In this study, all available records of stranded and incidentally caught…
A review of factors involved in zonation in Odontocete teeth, and an investigation of the likely impact of environmental factors and major life events on harbour porpoise tooth structure
Lockyer, C.
Report of the International Whaling Commission (1995)
Variation in zonation and Growth Layer Group (GLG) formation and underlying causes are reviewed. Five different types of anomaly were investigated in the teeth of harbour porpoise (Phocoena phocoena): pulp…
Life in the fast lane: The life history of harbor porpoises from the gulf of Maine
Read, Andrew J.; Hohn, Aleta A.
Marine Mammal Sci (1995)
We describe the life history of harbor porpoises in the Gulf of Maine by examining 239 animals killed in gill net fisheries and comparing these findings with the results of…

Blood chemistry of wild harbor porpoises Phocoena phocoena (L.)
Koopman, H. N.; Westgate, A. J.; Read, A. J.; Gaskin, D. E.
Marine Mammal Sci (1995)
Blood chemistry values were measured from 31 harbor porpoises (Phocoena phocoena) released from herring weirs in the Bay of Fundy, Canada. Sodium, phosphorus, calcium, chloride, magnesium, total protein, albumin, globulin,…
What do stranding data say about harbor porpoises (Phocoena phocoena)?
Polacheck, T.; Wenzel, F.W.; Early, G.
Report of the International Whaling Commission (1995)
The Smithsonian National Museum of Natural History maintains a centralized database on marine mammal strandings that occur along the eastern United States coastline. Data from this stranding database plus additional…
Retinal ganglion cell size and distribution predict visual capabilities of Dall’s porpoise
Murayama, Tsukasa; Somiya, Hiroaki; Aoki, Ichiro; Ishii, Takeo
Marine Mammal Sci (1995)
The structure of the retina, the distribution of ganglion cells, and the extent of the tapetum lucidum were studied in Dall's porpoise (Phocoenoides dalli) with the aim of understanding the…
Procedures and techniques applied by NINA for cutting, staining, mounting and ageing porpoise teeth
Kvam, T.
Report of the International Whaling Commission (1995)
Age determination of terrestrial mammals based on growth layers in the teeth has been a routine technique at NINA in Trondheim for many years. This paper describes how this well…
New approaches to studying the foraging ecology of small cetaceans
Read, Andrew J.
Developments in Marine Biology (1995)
Dolphins and porpoises spend the majority of their lives underwater, out of the view of human observers. Consequently, scientists have relied on indirect means to study the foraging ecology of…
Distribution, abundance, habitat use, and respiration patterns of harbor porpoise (Phocoena phocoena) off the northern San Juan Islands, Washington
Raum-Suryan, K. L.
Master's Thesis - San Jose State University (1995)
Boat and shore-based surveys were conducted from June to August 1991 and June to October 1992 to determine harbor porpoise distribution, density, abundance, and habitat use off the northern San…
