Temporal and spatial biosonar activity of the recently established uppermost Yangtze finless porpoise population downstream of the Gezhouba Dam: Correlation with hydropower cascade development, shipping, hydrological regime, and light intensity [PDF]
Ecology and EvolutionNumerous dams disrupt freshwater animals. The uppermost population of the critically endangered Yangtze finless porpoise has been newly formed below the Gezhouba Dam, however, information regarding the local porpoise is scarce.

Population-Level Laterality In Foraging Finless Porpoises [PDF]
Scientific Reports, 2021 Abstract Laterality has been reported in many vertebrates, and asymmetrical cerebral hemisphere function has been hypothesized to cause a left-bias in social behavior and a right-bias in feeding behavior. In this paper, we provide the first report of behavioral laterality in free-ranging finless porpoises, which seemingly supports the ...

Severe Hearing Loss in the World's First Successfully Captive-Born Yangtze Finless Porpoise: Impact of High Underwater Sound Exposure and Congenital Hearing Disorders. [PDF]
Integr ZoolThe audiogram of the world's first successfully captive‐born Yangtze finless porpoise was on average 40 dB higher than conspecifics. Congenital hearing disorders and noise exposure may be the primary cause of porpoise's hearing loss. ABSTRACT Aquariums globally have seen significant growth in recent decades.

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.
