NAMMCOSP (2003)
Wide-ranging methods that have been used to determine population structure, including distribution, life history, biology, ecological factors such as diet and contaminant loads, morphology and genetics, are reviewed. The importance…
Harbour porpoise (Phocoena phocoena) in the north Atlantic: Abundance, removals, and sustainability of removals
Stenson, G.B.
NAMMCOSP (2003)
The status of harbour porpoise (Phocoena phocoena) populations in the North Atlantic has raised numerous concerns. Although a number of factors that may be adversely affecting harbour porpoise populations have…
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…
Inferring ecological separation from regional differences in radioactive caesium in harbour porpoises Phocoena phocoena
Tolley, KA; Heldal, HE
Marine Ecology Progress Series (2002)
Geographic variation in the level of radioactive caesium-137 (137Cs) was examined from the axial muscle of 36 harbour porpoises Phocoena phocoena obtained as bycatch from 5 locations along the coast…
The effect of acoustic harassment devices on harbour porpoises (Phocoena phocoena) in the Bay of Fundy, Canada
Johnston, Dave W.
Biological Conservation (2002)
Many salmon aquaculture sites in the Bay of Fundy employ acoustic harassment devices (AHDs) to deter seals from approaching fish pens. These devices may also exclude harbour porpoises (Phocoena phocoena)…
Characteristics of echolocation signals used by a harbour porpoise (Phocoena phocoena) in a target detection experiment
Teilmann, Jonas; Miller, Lee A.; Kirketerp, Tim; Kastelein, Ronald A.; Madsen, Peter T.; Nielsen, Bjarke K.; Au, Whitlow W. L.
Aquatic Mammals (2002)
The characteristics of echolocation signals used by a harbour porpoise (Phocoena phocoena) during a target detection experiment are described. A water-filled steel sphere (either 5.08 or 7.62 cm in diameter)…
An automatic system for detecting and classifying the vocalisations of harbour porpoises
GILLESPIE, DOUGLAS; CHAPPELL, OLIVER
Bioacoustics (2002)
A system for automatically detecting the vocalisations of Harbour Porpoises Phocoena phocoena is described. The system consists of a high frequency hydrophone, an analogue electronics module and software running on…
