We examined the tooth ultra-structure of harbour porpoises (Phocoena phocoena) from Scottish waters to determine whether the incidence of mineralization anomalies could be related to certain life history events (e.g.…
An auditory study was conducted to derive data on temporary threshold shift (TTS) induced by single impulses. This information should serve as basis for the definition of noise exposure criteria…
Harbour porpoises Phocoena phocoena are protected under the Habitats and Species Directive (92/43/EEC) and listed as a priority species in the City and County of Swansea's Biodiversity Action Plan (BAP).…
The Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis) is endemic to the middle and lower reaches of the Yangtze River, China. It is the only freshwater population of porpoises in the…
(...) During April 1997 the acoustic detector was successfully used to detect vaquitas for the first time. On that occasion we surveyed on a fixed location, aboard an outboard motor…
In several publications, it was shown that echolocation sound generation in the nasal (epicranial) complex of toothed whales (Odontoceti) is pneumatically driven. Modern hypotheses consider the larynx and its surrounding…
Total and subcellular renal Zn, Cu, Se, Mn, V, Hg, Cd and Ag were determined by a mother–fetus pair of Dall’s porpoises (Phocoenoides dalli). All element concentrations in the maternal…
We examined the stomach contents of 87 finless porpoises (Neophocaena phocaenoides) in the Ariake Sound–Tachibana Bay area and Omura Bay in western Kyushu, Japan, between 1987 and 1992. Fish (Gobiidae…
Most of the data collected on the reproduction of harbour porpoises (Phocoena phocoena) comes from by-caught or stranded animals and is therefore opportunistic in nature. Harbour porpoises kept in a…
Harbour porpoise signals consist of directional, high frequency stereotypic clicks which can be logged using T-PODs. Variation in interclick intervals (ICIs) can be used to distinguish different acoustic behaviours. So…
