Background, Aim and ScopeThere are two species of fresh water cetaceans surviving in the Yangtze River system in China: Baiji (Lipotes vexillifer) and Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis). As a result of the expansion of human activities on the river, their distribution ranges appear to be decreasing and in the case of the Baiji, are even being restricted to several sections. The Baiji is the world’s most critically endangered cetacean species with a population… 
Population status, threats and conservation of the Yangtze finless porpoise
The Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis) is currently limited to the middle and lower reaches of the Yangtze River from Yichang to Shanghai, China, and the adjoining
The conservation of river cetaceans in the Yangtze River
Baiji, or Yangtze River Dolphin (Lipotes vexillifer) and the Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis) are two rare cetacean species endemic to the Yangtze River basin. The
Threats and opportunities for the survival of the Yangtze finless porpoise
The Yangtze finless porpoise (Neophocaena phocaenoides asiaorientalis), is a small freshwater cetacean which has recently fallen dramatically in number. It is an endemic species for the Yangtze River

Distribution patterns of Yangtze finless porpoises in the Yangtze River: implications for reserve management
The Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) is a highly threatened cetacean endemic to the middle and lower reaches of the Yangtze River that has suffered a dramatic
Population survey showing hope for population recovery of the critically endangered Yangtze finless porpoise
Abstract The Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis), has experienced rapid declines in recent decades. We estimate its abundance based on surveys conducted between
Indo-Pacific Humpback Dolphins: A Demographic Perspective of a Threatened Species
The use of demographic analysis is described to quantify population trend and, more informatively, predict the risk (probabilities) of extinction, and it is shown the power of demographic analyses, predicting a significant population decline before it is directly documented by other standard techniques.
Common pattern of population decline for freshwater cetacean species in deteriorating habitats
Empirical data of the likely extinction of baiji strongly agree with the simulation exercise, implying that extinction of other freshwater cetacean species may occur sooner than previously considered, and precautionary approaches for habitat restoration and landscape management should be implemented.
Microsatellite variation and significant population genetic structure of endangered finless porpoises (Neophocaena phocaenoides) in Chinese coastal waters and the Yangtze River
The results strongly support the classification of porpoises in these regions into distinct evolutionarily significant units, including at least two separate species, and therefore they should be treated as different management units in the design and implementation of conservation programmes.
Biodiversity and the Three Gorges Reservoir: a troubled marriage
The Three Gorges region, located on the upper reaches of the Yangtze River in central China, is considered one of the most important biodiversity hotspots in China. It harbours more than 6000 plant


Aquatic Resource Conservation. The first Yangtze finless porpoise successfully born in captivity (4 pp)
The successful birth of this calf confirms that it is possible to breed the Yangtze finless porpoise in captivity, and will greatly benefit the conservation efforts, and also greatly bolster the on-going efforts to study the reproductivebiology of these animals.
The population of finless porpoise in the middle and lower reaches of Yangtze River
Based upon the data of ecological surveys of finless porpoise, Neophocaena phoca-enoides, in the middle and lower reaches of the yangtze River and specimens collected in recent years, the current
Conservation options for the Baiji: time for realism?
The baiji, or Yangtze River dolphin (Lipotes vexillifer), has become something of a cause célèbre in conservation biology over the last 15 years due to its high-profile, critically endangered status

It is taken issue with the assertion of Yang et al. (2006 (this issue) that the baiji has been a conservation cause celebre over the last 15 years and a call for plain talk and what those authors call "realism" is long overdue.

Japanese cetacean harvest will continue supported by domestic demand for whale products as long as the proceeds can sustain the operation, even with criticisms from outside communities.
