The Journal of the Acoustical Society of America, 2007 Acoustic and concurrent behavioral data from one neonatal male Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis) in captivity were presented. The calf click train was first recorded at 22days postnatal, and the frequency of hydrophone-exploration behavior with head scanning motions in conjunction with emissions of click trains by the ...

The Yangtze finless porpoise: On an accelerating path to extinction?
Biological Conservation, 2014 For the conservation of endangered animals to be effective, information on population distribution and abundance requires regular updating from census efforts. The Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) has recently been reclassified as critically endangered (CR) due to a rapid decline in abundance.

Population status, threats and conservation of the Yangtze finless porpoise [PDF]
Science Bulletin, 2009 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 Poyang and Dongting Lakes. Its population size has decreased remarkably during the last several decades due to the heavy impact of human activities ...

Saving the Yangtze finless porpoise: Time is rapidly running out
Biological Conservation, 2017 Abstract The Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) is the world's only freshwater porpoise and is endemic to the Yangtze River. However, it is now Critically Endangered, with its long-term survival very uncertain due to escalating anthropogenic pressure.

Respiratory pattern of captive Yangtze finless porpoises (Neophocaena phocaenoides asiaeorientalis)
Journal of Ethology, 2006 Cetacean respiration usually happen in bouts. The most widely applied quantitative method used to analyze the structure of these bouts is the log(e)-survivorship analysis, based on the assumption that the respiratory intervals are distributed as negative
