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.

Evaluation of the survival of Yangtze finless porpoise under probabilistic hesitant fuzzy environment

International Journal of Intelligent Systems, 2022
Considering the significant advantages of probabilistic hesitant fuzzy sets (PHFSs) in the multicriteria decision‐making (MCDM) problems and the limitations of existing methods for PHFSs, we develop an improved probabilistic hesitant fuzzy MCDM (PHF‐MCDM)

An artificial intelligence recognition algorithm for Yangtze finless porpoise

OCEANS 2015 - MTS/IEEE Washington, 2015
Processing marine-mammal signals for species classification and monitoring of endangered marine mammals are problems that have recently attracted attention in the scientific literature. Currently, the detection of signals of interest is typically accomplished through a combination of visual inspection of spectrograms and listening to the data.

The Association of Seasonal Dietary Shift with Fecal Metabolome and Microbiota in the Captive Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis).

Environmental Research
The gut microbiota can act as a buffer against changes in energy and food availability and adapt plastically to fluctuations in the host's diet. However, it is unknown how changes in the gut microbiome with the seasons impact microbial metabolism and the

Spatial distribution, trophic magnification, and risk assessment of per- and polyfluoroalkyl substances in Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis): Risks of emerging alternatives.

Journal of Hazardous Materials
The Yangtze finless porpoise (YFP, Neophocaena asiaeorientalis asiaeorientalis) is the only freshwater cetacean found in China. However, per- and polyfluoroalkyl substances (PFASs) risks in YFPs remain unclear.
