Although the stock relationships among harbour porpoise (Phocoena phocoena) in the Northwest Atlantic are unknown, it has been postulated that there are 4 local populations: Bay of Fundy/Gulf of Maine,…
Investigation of aspects of the life history of the harbour porpoise, Phocoena phocoena, in British waters
Lockyer, C.
Report of the International Whaling Commission (1995)
Specimens of harbour porpoises, Phocoena phocoena, from strandings and bycatches in fisheries around the British Isles between 1985 and September 1994 have been examined. Full autopsies were undertaken on most…

Lockyer, C.
Report of the International Whaling Commission (1995)
Specimens of harbour porpoises, Phocoena phocoena, from both strandings and bycatch in fisheries around the United Kingdom between 1985 and 1994 have been examined. Full autopsies were undertaken on most…

Bjorge, A.; Hohn, A.A.; Kvam, T.; Lockyer, C.; Schweder, T.; Aarefjord, H.
Report of the International Whaling Commission (1995)
A workshop on age determination in harbour porpoises (Phocoena phocoena) was held in Oslo, Norway, 21-23 May 1990. During the workshop, the principles of formation of dental layers were reviewed,…
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…
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…
Reproduction in the porpoises (Phocoenidae): Implications for management
GASKIN, D. E.; SMITH, G. J. D.; WATSON, A. P.; YASUI, W. Y.; YURICK, D. B.
Report of the International Whaling Commission (1984)
The population biology of most phocoenid species is still rather poorly understood. It is important that we improve our knowledge in view of concerns which have been expressed in recent…
Developmental patterns in osteology and external morphology in Phocoena phocoena
Stuart, L.J.; Morejohn, G.V.
Report of the International Whaling Commission (1980)
Dentinal growth layer groups (GLGs) in teeth were counted for 84 beach-cast specimens of Phocoena phocoena from the northeastern Pacific (mostly California). Measurements of external, cranial, and postcranial traits were…
