Population Prediction of Finless Porpoise in the Yangtze River

Highlights in Science, Engineering and Technology, 2023
Finless porpoise is the only freshwater mammal in the Yangtze River basin, which has suffered a plummet in population these years. Our team mainly used Improved Leslie Population Model and Improved Differential Equation Model to predict the change of its population.

Underwater Noise Level Recordings from a Water Intake Pontoon and Possible Impacts on Yangtze Finless Porpoises in a Natural Reserve

Animals, 2022
Underwater noise pollution caused by human activities may affect freshwater cetaceans to different degrees. To analyze the impacts of water intake pontoons on Yangtze finless porpoises (Neophocaena asiaeorientalis), this study collected underwater noise ...

A real-time passive acoustic monitoring system to detect Yangtze finless porpoise clicks in Ganjiang River, China

Frontiers in Marine Science, 2022
Phocoenidae live in fresh, coastal waters where they often share a significant portion of their habitat with humans. As a result, local activities (e.g., coastal fisheries and shipments) cause underwater noise pollution and threaten their ecosystem.

Spatiotemporal relationships of threatened cetaceans and anthropogenic threats in the lower Yangtze system

Frontiers in Conservation Science, 2022
The impacts of fisheries interactions on cetaceans can be challenging to determine, often requiring multiple complementary investigative approaches. The Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis), one of the few Critically ...

Impacts of Sand Mining Activities on the Wetland Ecosystem of Poyang Lake (China)

Land, 2022
Increasing anthropogenic activities are threatening freshwater ecosystems worldwide. Sand mining in Poyang Lake has significantly impacted the wetland ecosystem over the past 20 years, yet a quantitative analysis of these impacts remains insufficient ...

Hearing pathways in the Yangtze finless porpoise,Neophocaena asiaeorientalis asiaeorientalis [PDF]

Journal of Experimental Biology, 2013
SummaryHow an animal receives sound may influence its use of sound. While "jaw hearing" is well supported for odontocetes, examining how sound is received across the head work has been limited to a few representative species. The substantial variation in jaw and head morphology among odontocetes suggests variation in sound reception.
