Acta Zoologica (2006)
Epiphyseal development was investigated on X-rays of flippers from 158 harbour porpoises from Danish waters. Development followed a proximodistal pattern similar to what is known in other cetacean species. Ossification…
Differences in the response of a striped dolphin (Stenella coeruleoalba) and a harbour porpoise (Phocoena phocoena) to an acoustic alarm
Kastelein, R.A.; Jennings, N.; Verboom, W.C.; de Haan, D.; Schooneman, N.M.
Marine Environmental Research (2006)
Small cetacean bycatch in gillnet fisheries may be reduced by deterring odontocetes from nets acoustically. However, different odontocete species may respond differently to acoustic signals from alarms. Therefore, in this…
Pathological findings in harbour porpoises (Phocoena phocoena) from Norwegian and Icelandic waters
Siebert, U.; Tolley, K.; Víkingsson, G. A.; Ólafsdottir, D.; Lehnert, K.; Weiss, R.; Baumgärtner, W.
Journal of Comparative Pathology (2006)
A study of 37 by-caught harbour porpoises from Icelandic and Norwegian waters showed that most were in good or moderate nutritional condition and none was severely emaciated. Mild infection with…
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…
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…
