Interaction Analysis in Hunting Behavior of Finless Porpoises

2019 Asia-Pacific Signal and Information Processing Association Annual Summit and Conference (APSIPA ASC), 2019
Finless porpoises (Neophocaena asiaeorintalis) usually live in a relatively small group. Aggregated porpoises prey on fish simultaneously and they do not show explicit allotted roles like other dolphins. However, whether each individual hunt fish independently from others is not clear.

An automatic identification algorithm of Yangtze finless porpoise

2015 IEEE International Conference on Signal Processing, Communications and Computing (ICSPCC), 2015
This paper describes the time-frequency features of the Yangtze finless porpoise acoustic signals firstly. Then an automatic identification algorithm for the Yangtze finless porpoise is presented based on Hilbert Huang Transform and BP artificial neural network. The algorithm includes two steps: feature extraction and signal identification.

Behavioral laterality in Yangtze finless porpoises ( Neophocaena asiaeorientalis asiaeorientalis )

Behavioural Processes, 2017
The Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) is a critically endangered species with less than 1000 individuals expected to be left in the wild. While many studies have been conducted on laterality among several cetacean species, no studies investigating the Yangtze finless porpoise have been conducted.

Thresholds of population persistence for the Yangtze finless porpoise: implications for conservation managements

Integrative Zoology, 2021
AbstractThe Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis), a critically endangered species, is the only cetacean species in the Yangtze River following the functional extinction of baiji (Lipotes vexillifer). To inform conservation actions, two important questions need to be addressed: what is the threshold value of survival ...

Comparison of stationary acoustic monitoring and visual observation of finless porpoises

The Journal of the Acoustical Society of America, 2009
The detection performance regarding stationary acoustic monitoring of Yangtze finless porpoises Neophocaena phocaenoides asiaeorientalis was compared to visual observations. Three stereo acoustic data loggers (A-tag) were placed at different locations near the confluence of Poyang Lake and the Yangtze River, China.
