Serious concerns have been raised regarding the status of the harbour porpoise populations in the North Atlantic and specifically for those inhabiting Atlantic Canadian waters. In 1991 harbour porpoise in…
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…
Current knowledge on harbour porpoises (Phocoena phocoena) in the Baltic Sea
Koschinski, Sven
Ophelia (2001)
Concern has been raised about the long-term viability of the harbour porpoise population in the Baltic Sea. Bycatch at possibly unsustainable levels, contaminants, overfishing of prey species and disturbance have…
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…
Post-mortem findings in harbour porpoises (Phocoena phocoena) from the German North and Baltic Seas
Siebert, U.; Wünschmann, A.; Weiss, R.; Frank, H.; Benke, H.; Frese, K.
Journal of Comparative Pathology (2001)
Between 1991 and 1996, necropsies were performed on 445 harbour porpoises (Phocoena phocoena), in various states of preservation, stranded on German coasts or accidentally caught by German fishermen. The animals…
Oxygen consumption and swim speed of the harbor porpoise Phocoena phocoena
Otani, Seiji; Naito, Yasuhiko; Kato, Akiko; Kawamura, Akito
Fisheries Science (2001)
The rate of oxygen consumption and energetic cost of locomotion of captive harbor porpoises Phocoena phocoena were studied in Hokkaido, Japan, using respirometry together with externally attached devices (a data…
Abundance of harbour porpoise and other cetaceans in the North Sea and adjacent waters
Hammond, P.S.; Berggren, P.; Benke, H.; Borchers, D.L.; Collet, A.; Heide-Jørgensen, M.P.; Heimlich, S.; Hiby, A.R.; Leopold, M.F.; Øien, N.
Journal of Applied Ecology (2002)
The status of small cetaceans in the North Sea and adjacent waters has been of concern for many years. Shipboard and aerial line transect surveys were conducted to provide accurate…
Geographical variation in harbour porpoise (Phocoena phocoena) skulls: Support for a separate non-migratory population in the Baltic proper
Huggenberger, S.; Benke, H.; Kinze, C.C.
Ophelia (2002)
We measured metric and scored non-metric characters of 242 harbour porpoise (Phocoena phocoena) skulls from the North and the Baltic Sea and subdivided them into three geographical areas: The German…
Post-mortem findings and causes of death of harbour porpoises (Phocoena phocoena) stranded from 1990 to 2000 along the coastlines of Belgium and northern France
Jauniaux, T.; Petitjean, D.; Brenez, C.; Borrens, M.; Brosens, L.; Haelters, J.; Tavernier, T.; Coignoul, F.
Journal of Comparative Pathology (2002)
Between the years 1990 and 2000, an attempt was made to determine the causes of death of 55 harbour porpoises stranded along the Belgian and northern French coasts. From 1990…
Small-scale population structure of eastern North Pacific harbour porpoises (Phocoena phocoena) indicated by molecular genetic analyses
Chivers, S. J.; Dizon, A. E.; Gearin, P. J.; Robertson, K. M.
Journal of Cetacean Research and Management (2002)
Concern about the conservation and management of harbour porpoise (Phocoena phocoena) populations, which have experienced relatively large incidental fishery kills in localised areas throughout their range, has prompted research to…
