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.…
Construction of ethogram of the captive Yangtze finless porpoises, Neophocaena phocaenoides asiaeorientalis
Xiao, J.; Wang, D.
Acta Hydrobiologica Sinica (2005)
Quantitative study of behavior should be preceded by precise description and definition of behavior. Therefore, an ethogram, which includes the comprehensive descriptions of the characteristic behavior of a species, should…
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…
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…
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 genetic structure of the Yangtze Finless Porpoise (Neophocaena phocaenoides asiaeorientalis): Implications for management and conservation
Zheng, Jin-Song; Xia, Jun-Hong; He, Shun-Ping; Wang, Ding
Biochem Genet (2005)
Understanding the population genetic structure is a prerequisite for conservation of a species. The degree of genetic variability characteristic of the mitochondrial DNA control region has been widely exploited in…
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…
A review of acoustic surveys and conservations actions for the vaquita
JARAMILLO-LEGORRETA, A.; ROJAS-BRACHO, L.; URBAN, J.
Scientific Committee Meeting Documents (2005)
In the first part of this report we present our results, so far, derived from the application of passive acoustic techniques to study the habitat use of vaquita. In the…
Polybrominated diphenyl ethers (PBDEs) and organochlorines in small cetaceans from Hong Kong waters: Levels, profiles and distribution
Ramu, Karri; Kajiwara, Natsuko; Tanabe, Shinsuke; Lam, Paul K.S.; Jefferson, Thomas A.
Marine Pollution Bulletin (2005)
Polybrominated diphenyl ethers (PBDEs) and organochlorine compounds (OCs) were determined in the blubber, liver and kidney of Indo-Pacific humpback dolphins (Sousa chinensis) and finless porpoises (Neophocaena phocaenoides) stranded in Hong…
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…
