Identification of the first harbour porpoise (Phocoena phocoena) calving ground in the North Sea

Sonntag, R. P.; Benke, H.; Hiby, A. R.; Lick, R.; Adelung, D.
Journal of Sea Research (1999)

We investigated the occurrence of harbour porpoises in the North Sea off Schleswig-Holstein by conducting aerial surveys with emphasis on calves. Fourteen per cent of the sighted porpoises off the…

A note on radionuclide 137Cs and 40K concentrations in Dall’s porpoises, Phocoenoides dalli, in coastal waters of Japan

Kasamatsu, F.; Kawabe, K.; Inatomi, N.; Murayama, T.;
Journal of Cetacean Research and Management (1999)

Concentrations of artificial radionuclide 137Cs and natural radionuclide 40K in Dall's porpoise, Phocoenoides dalli, from the Pacific coast of northern Japan in 1996 are presented. Concentrations of 137Cs in muscle…

Target detection by an echolocating harbor porpoise (Phocoena phocoena)

Kastelein, R. A.; Au, W. W. L.; Rippe, H. T.; Schooneman, N. M.
The Journal of the Acoustical Society of America (1999)

Two echolocation experiments are described. They were conducted on the same harbor porpoise housed in a sea pen, one year apart at Neeltje Jans, The Netherlands. The aims were to…

Examining the risk of inbreeding depression in a naturally rare cetacean, the vaquita (Phocoena sinus)

Taylor, Barbara L.; Rojas-Bracho, Lorenzo
Marine Mammal Sci (1999)

Uncertainty about the magnitude of various risks facing endangered species can paralyze conservation action. The vaquita is a naturally rare porpoise that has declined to the low hundreds of individuals…

Application of a new method to investigate population structure in the harbour porpoise, Phocoena phocoena, with special reference to the North and Baltic Seas

Lockyer, C.
Journal of Cetacean Research and Management (1999)

Tooth ultrastructure in harbour porpoise is examined as a possible tool for differentiating between animals from different geographical regions in the North Atlantic. Nine different characteristics in both dentine and…

Age, growth, and reproductive patterns of Dall’s porpoise (Phocoenoides dalli) in the central north Pacific ocean

Ferrero, Richard C.; Walker, William A.
Marine Mammal Sci (1999)

Life history parameters were estimated for Dall's porpoise, Phocoenoides dalli, from biological specimens collected in the western Aleutian Islands, during 1981–1987. Of 2,033 males and 3,566 females examined, reproductive data…
