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 ...

The ontogeny of echolocation in a Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis)

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 ...

Habitat preference of the Yangtze finless porpoise in a minimally disturbed environment

Ecological Modelling, 2017
Abstract Analyses of animal species distribution in a neutral or minimally-interrupted habitat provide a baseline that is essential for assessment of population status, identification of key habitat, and conservation planning for habitat protection and restoration. In this study, we surveyed the occurrence of the Yangtze finless porpoise (Neophocaena

APPLICABILITY OF CETACEAN MICROSATELLITE PRIMERS IN THE YANGTZE FINLESS PORPOISE

Acta Hydrobiologica Sinica, 2004
Application of microsatellites in the Yangtze finless porpoise ( Neophocaena phocaenoides asiaeorientalis) has not been reported. In this study amplification of microsatellites were performed in DNA samples of the Yangtze finless porpoise population by ...
