Morphology of the modern cetaceans represents the results of adaptation of the ancestral terrestrial mammals to aquatic life through their evolutional processes. Some of the primitive fossil cetaceans are known…
Stranded harbour porpoises were analysed to investigate differences in stranding patterns along the North and Baltic Sea coasts of Schleswig-Holstein, Germany. A total of 1,015 stranded or bycaught harbour porpoises…
Throughout its range, the distribution of the harbour porpoise (Phocoena phocoena L.) has contracted significantly in the last century, particularly in the North Sea. Reasons for this decline have been…
This report summarises the available knowledge on odontocete (toothed whale) distribution, behaviour, migration and threats and was compiled for the Bonn Secretariat of CMS.
The Yangtze finless porpoise, Neophocaena phocaenoides asiaeorientalis, is an endangered small cetacean that occurs only in the middle and lower reaches of the Yangtze River of China. The establishment of…
To observe the bio-sonar behavior of dolphins and porpoises, a miniature stereo acoustic data logger was developed to record the echolocation clicks of small cetaceans. The 'A-tag' device is small…
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)…
Reproductive behaviors are poorly known for the Yangtze finless porpoise Neophocaena phocaenoides asiaeorientalis. In this study, the parentage of an isolated Yangtze finless porpoise population inhabiting the Yangtze Tian-e-Zhou Baiji…
Little is known about the biology of Burmeister’s porpoises (Phocoena spinipinnis), a small cetacean species endemic to South American waters. Information on stock structure, however, is urgently needed, as the…
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.…
