Accumulation and risk prioritization of psychoactive substances in the critically endangered Yangtze finless porpoise

Journal of Hazardous Materials, 2023
Psychoactive substances have been identified as a kind of emerging contaminants in aquatic environment and pose potential adverse effects on aquatic animals. Yangtze finless porpoise, a critically endangered species in China, is also facing the threat of psychoactive substances. In this study, the accumulation characteristics and risk prioritization of

Effects of fish community on occurrences of Yangtze finless porpoise in confluence of the Yangtze and Wanhe Rivers

Environmental Science and Pollution Research, 2015
The Yangtze finless porpoise is a subspecies of narrow-ridged finless porpoise endemic to the middle and lower reaches of the Yangtze River and the adjoining Poyang and Dongting Lakes. With the depletion of fish stocks in the Yangtze River in recent decades, food availability has become the most important factor affecting the survival of this ...

Range contraction of the Yangtze finless porpoise inferred from classic Chinese poems

Current Biology
Understanding and quantifying the historical range of threatened species can help inform conservation and restoration1. Most studies use specimen data, molecular evidence or past surveys to reconstruct historical ranges. However, historical documents provide a unique opportunity to reconstruct species' distributions and ranges, offering new ...

Isolation and identification of pathogenic Aeromonas veronii from a dead Yangtze finless porpoise

Diseases of Aquatic Organisms, 2018
Diseases caused by Aeromonas veronii in freshwater fish have been widely reported, but other species such as aquatic mammals have probably been overlooked. Here, we identified one isolate of A. veronii from a Yangtze finless porpoise Neophocaena asiaeorientalis asiaeorientalis exhibiting disease and mortality, and subsequently confirmed its virulence ...

Role of air sinuses in sound reception of the Yangtze finless porpoise: A numerical study

The Journal of the Acoustical Society of America
Although air sinuses are prevalent in odontocetes and are an integral component of their sound reception system, the acoustic function of these air-filled structures remains largely unknown. To address this, we developed a numerical model using computed tomography data from a Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) to ...

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 ...
