Survey results from 1989 to 1992 were interpreted as indicating that about 700 finless porpoises (Neophocaena phocaenoides) inhabited the section of the lower Yangtze River between Nanjing and Hukou. The…
The mitochondrial DNA control region of 12 finless porpoises (Neophocaena phocaenoides) from the Yangtze River, Yellow Sea, and South China Sea, was amplified. Two portions, 317 and 245 base pairs,…
Water development projects, including dams, embankments, and ship locks, have had extensive deleterious effects on two species of river cetacean in China: the baiji (Lipotes vexillifer) and the Yangtze population…
Three finless porpoises (Neophocaena phocaenoides) from the Yangtze River were fitted with cotton cloth vests and small radio transmitters. They were tracked for 2.6, 11.0, and 14.6 days in the…
During 1991–1997, five and three surveys were conducted in the middle and lower reaches, respectively, of the Yangtze River. The target species of the surveys included both the baiji (Lipotes…
To clarify population structure of finless porpoises (Neophocaena phocaenoides) in Japan, we examined mitochondrial DNA sequences of 174 animals. All individuals except for a female were collected in 5 geographically…
The taxonomy of the finless porpoise (Neophocaena phocaenoides), while better-studied than that of many species of small cetaceans, still suffers from some uncertainties and a general lack of data from…
To clarify population structure of finless porpoises (Neophocaena phocaenoides) in Japan, a sequence of studies have been conducted: a questionnaire survey and aerial sighting surveys to obtain information on porpoise…
The authors made 39 surveys (a total of 161 days) in the Tian-e-Zhou Oxbow of the Yangtze River, China, for observing 13 Yangtze finless porpoises (Neophocaena phocaenoides asiaeorientalis) captured from…
Irrawaddy dolphins Orcaella brevirostris and finless porpoises Neophocaena phocaenoides are referred to as facultative freshwater cetaceans because they occupy both fresh- and nearshore marine waters. In Asia, the especially rapid…
