Individual variability of echolocation and diving behavior of Yangtze finless porpoises
The Journal of the Acoustical Society of America, 2012Passive acoustic monitoring has been widely applied to observe the presence, movement and behavior of the target species. For quantitative analysis, the acoustic cue production rate of the target animals must be observed in advance. We examined the detailed pattern of biosonar and swimming behaviors of 10 Yangtze finless porpoises (1 female and 9 males)

In Vitro Cellular & Developmental Biology - Animal, 2011
The Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis), as the sole freshwater subspecies of N. phocaenoides, is endemic to the Yangtze River and its adjacent lakes. Its population has declined significantly over recent decades. In this study, we established a skin-derived finite fibroblast cell line of the Yangtze finless porpoise ...

Background Information of Poyang Lake and Yangtze Finless Porpoises
2012Before I start describing Yangtze finless porpoises (YFPs), I need to put this animal and the need to protect it into context. Therefore, this chapter seeks to introduce the area, Poyang Lake, and identify major use conflicts with respect to ecology and economy.

Isolation and identification of pathogenic Aeromonas veronii from a dead Yangtze finless porpoise
Diseases of Aquatic Organisms, 2018Diseases caused by Aeromonas veronii in freshwater fish have been widely reported, but other species such as aquatic mammals have probably been overlooked. Here, we identified one isolate of A. veronii from a Yangtze finless porpoise Neophocaena asiaeorientalis asiaeorientalis exhibiting disease and mortality, and subsequently confirmed its virulence ...

Suckling behavior and its development in two Yangtze finless porpoise calves in captivity
Zoo Biology, 2011AbstractWe focally observed the suckling behavior of two Yangtze finless porpoise calves, C05 and C07, in captivity. Between 15 and 730 days postpartum of C05 and between birth and 30 days postpartum of C07, 286.3 (1.9 ± 0.4 hr/day (mean ± standard deviation), n = 148 days) and 18.3 hr (2.0 ± 0.5 hr/day, n = 9 days) of video footage were recorded, in ...

Role of air sinuses in sound reception of the Yangtze finless porpoise: A numerical study
The Journal of the Acoustical Society of AmericaAlthough air sinuses are prevalent in odontocetes and are an integral component of their sound reception system, the acoustic function of these air-filled structures remains largely unknown. To address this, we developed a numerical model using computed tomography data from a Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) to ...

Range contraction of the Yangtze finless porpoise inferred from classic Chinese poems
Current BiologyUnderstanding and quantifying the historical range of threatened species can help inform conservation and restoration1. Most studies use specimen data, molecular evidence or past surveys to reconstruct historical ranges. However, historical documents provide a unique opportunity to reconstruct species' distributions and ranges, offering new ...

Ethogram of Yangtze finless porpoise calves (Neophocaena phocaenoides asiaeorientalis).
Dong wu xue yan jiu = Zoological research, 2011Underwater behavioral patterns of one Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis) calf in captivity and those performed on the water surface by two calves in semi-natural environment were focally followed and continuously recorded until one year postpartum to construct the ethogram.
