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,…
Relationships between polychlorinated biphenyls and health status in harbor porpoises (Phocoena phocoena) stranded in the United Kingdom
Jepson, Paul D.; Bennett, Peter M.; Deaville, Robert; Allchin, Colin R.; Baker, John R.; Law, Robin J.
Environmental Toxicology and Chemistry (2005)
To investigate possible relationships between polychlorinated biphenyl (PCB) exposure and infectious disease mortality in harbor porpoises (Phocoena phocoena) in United Kingdom waters, summed blubber concentrations of 25 chlorobiphenyl congeners (Σ25CB)…
Harbour porpoises (Phocoena phocoena): Investigation of density, distribution patterns, habitat use and acoustics in the German North and Baltic Seas
Siebert, Ursula; Benke, Harald; Dehnhardt, Guido; Gilles, Anita; Hanke, Wolf; Honnef, Christopher G; Lucke, Klaus; Ludwig, Stefan; Scheidat, Meike; Verfuß, Ursula K
Offshore Wind Energy (2005)
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…
Diet overlap between harbour porpoise and bottlenose dolphin: An argument in favour of interference competition for food?
Spitz, Jérôme; Rousseau, Yann; Ridoux, Vincent
Estuarine, Coastal and Shelf Science (2006)
In aquatic ecosystems, competitive interactions are occasionally described. Violent attacks on harbour porpoises by bottlenose dolphins were reported and it was proposed that this behavior could result from competitive interactions…
