Two species of cetaceans live in the Yangtze river (Changjiang R.): Lipotes vexillifer (MILLER, 1918) and Neophocaena asiaeorientalis (PILLERI and GIHR, 1972). Both species are only found in the middle…

An account is given of observations on two dolphin species Sousa plumbea and Neophocaena phocaenoides which belong to the typical fauna of the Indus Delta. Sousa is a permanent inhabitant…
Two species of dolphin inhabit the Changjiang (Yangtze): Lipotes vexillifer MILLER, 1918 (known as Baiji in Chinese) and the Finless porpoise, Neophocaena asiaeorientalis PILLERI and GIHR, 1972. Although quite a…
The Bay of Fundy is a known area of concentration of Phocoena phocoena during the summer months. In this study, 698 females with calves and 5 473 porpoises of other…
The distribution of the harbour porpoise Phocoena phocoena (L.). is re-examined using a compilation of all available recent information. Three isolated major populations of this species exist: in the North…
The population biology of most phocoenid species is still rather poorly understood. It is important that we improve our knowledge in view of concerns which have been expressed in recent…
The vaquita (Phocoena sinus) is a small porpoise found only in the northern Gulf of California. This species may have been subject to high levels of mortality in the gill-net…
The small cetacean catch by artisanal fishermen in Peru was the subject of a IUCN/UNEP project in 1985–1986. In a follow-up study during 1987 we monitored the port of Pucusana,…
This paper reports the population status of the endangered Chinese River dolphin - Lipotes vexillifer, the factors causing the population decline of Lipotes and protective measures adopted in recent years,…
We estimated the potential intrinsic rate of increase (r) of the harbour porpoise (Phocoena phocoena) population in the Bay of Fundy and Gulf of Maine using empirical data on reproductive…
