Harbour porpoises are widely distributed in the seas around Denmark. Total abundance in Danish waters is estimated as approximately 100,000 animals. Population density varies considerably by area. There are probably…
The reported decline of the harbour porpoise in the coastal areas of the North Sea after 1940, has also been seen in Dutch waters. Information on the distribution and abundance…
This paper summarises current knowledge of the three populations of harbour porpoises in US and Canadian Atlantic waters. During the summer, the populations are centred in the Gulf of Maine/Bay…
Tidal-stream habitats present periodically fast-flowing, turbulent conditions. Evidence suggests that these conditions benefit top predators such as harbour porpoises Phocoena phocoena, presumably allowing them to optimise exploitation of prey resources.…
Polybrominated diphenyl ethers (PBDEs) are one of the flame retardants widely used in plastics, textiles, electronic appliances, and electrical household appliances. In this study, PBDEs and organochlorine compounds (OCs) were…
We used stable carbon (δ13 C) and nitrogen (δ15 N) isotope analysis to investigate the trophic ecology of 8 small cetacean species of the southwestern South Atlantic Ocean: 6 delphinids…
The presence of tattoo skin disease (TSD) was examined in 1392 free-ranging and dead odontocetes comprising 17 species from the Americas, Europe, South Africa, New Zealand and Greenland. We investigated…
Boat surveys along randomly placed line transects were conducted from June to August 1991 and June to October 1992 to determine distribution and abundance of and habitat use by harbor…
The harbour porpoise (Phocoena phocoena) is an important top predator and as such an indicator species for its environment. Before the beginning of the 21st century, little data existed on…
We detail the first direct, at sea monitoring of small cetacean interactions with Peruvian artisanal drift gillnet and longline fisheries. A total of 253 small cetaceans were captured during 66…
