The harbour, or common, porpoise (Phocoena phocoena) is the smallest cetacean inhabiting temperate to cold waters throughout the northern hemisphere. Due to its occurrence mainly but not exclusively in coastal…
Sexually dimorphic proportions of the harbour porpoise (Phocoena phocoena) skeleton
Galatius, Anders
Journal of Anatomy (2005)
Sexual differences in growth, allometric growth patterns and skeletal proportions were investigated by linear measurements of skeletal parts on 225 harbour porpoises (Phocoena phocoena) from the inner Danish and adjacent…
Receiving beam patterns in the horizontal plane of a harbor porpoise (Phocoena phocoena)
Kastelein, Ronald A.; Janssen, Mirjam; Verboom, Willem C.; de Haan, Dick
The Journal of the Acoustical Society of America (2005)
Receiving beam patterns of a harbor porpoise were measured in the horizontal plane, using narrow-band frequency modulated signals with center frequencies of 16, 64, and 100kHz. Total signal duration was…
Investigations of the potential influence of environmental contaminants on the thymus and spleen of harbor porpoises (Phocoena phocoena)
Beineke, Andreas; Siebert, Ursula; McLachlan, Michael; Bruhn, Regina; Thron, Kristina; Failing, Klaus; Müller, Gundi; Baumgärtner, Wolfgang
Environmental Science & Technology (2005)
Harbor porpoises from the German North and Baltic Seas exhibit a higher incidence of bacterial infections compared to whales from less polluted arctic waters. The potential adverse effect of environmental…
Spatial orientation in echolocating harbour porpoises (Phocoena phocoena)
Verfuss, U. K.
Journal of Experimental Biology (2005)
Studies concerning the echolocation behaviour of odontocetes focus mainly on target detection and discrimination, either in stationary animals or in animals approaching a specific target. We present the first data…
Relative abundance of harbour porpoises (Phocoena phocoena) from acoustic and visual surveys of the Baltic Sea and adjacent waters during 2001 and 2002
Gillespie, D.; Berggren, P.; Brown, S.; Kuklik, I.; Lacey, C.; Lewis, T.; Matthews, J.; McLanaghan, R.; Moscrop, A.; Tregenza, N.
Journal of Cetacean Research and Management (2005)
Boat-based acoustic and visual surveys for harbour porpoises (Phocoena phocoena) were conducted during the summers of 2001 and 2002 in order to investigate their distribution and relative abundance in the…
Post-mortem stability of blubber retinoids in by-caught harbour porpoises (Phocoena phocoena): Implications for the design of biomarker studies
Tornero, V.; Borrell, A.; Pubill, E.; Koopman, H.; Read, A.; Reijinders, P. J. H.; Aguilar, A.
Journal of Cetacean Research and Management (2005)
The effect of post-mortem time (0-48 hours) on retinoid concentrations in the blubber and liver of harbour porpoises under natural conditions is investigated to assess the stability of samples collected…
Bilateral directional asymmetry of the appendicular skeleton of the harbor porpoise (Phocoena phocoena)
Galatius, Anders; Jespersen, Ase
Marine Mammal Sci (2005)
Directional asymmetry (DA) of the lengths, diameters, and masses of the scapula, humerus, radius, and ulna were analyzed on a sample of 213 harbor porpoises from Denmark and West Greenland.…
Diel variation in echolocation behavior of wild harbor porpoises
Carlstrom, Julia
Marine Mammal Science (2005)
The echolocation rate and behavior of wild harbor porpoises were studied using a harbor porpoise click detector (POD) deployed close to the bottom at 40 m depth in Scottish waters,…
Population structure and historical demography of eastern North Atlantic harbour porpoises inferred through mtDNA sequences
Tolley, KA; Rosel, PE
Marine Ecology Progress Series (2006)
The harbour porpoise Phocoena phocoena experiences high rates of incidental mortality in commercial fisheries, and in some areas these rates are sufficiently high to justify concern over population sustainability. Given…
