Shifts in Fish Assemblages and Yangtze Finless Porpoise (Neophocaena asiaeorientalis) Prey Selection in Poyang Lake During the Early Phase of the Decadal Fishing Moratorium

Diversity
Yangtze finless porpoise (Neophocaena asiaeorientalis) is the only extant cetacean species in the Yangtze River, a national first-class protected wild animal in China, and a key indicator reflecting the health status of the Yangtze River ecosystem ...

Effects of bycatch on the population viability of the narrow-ridged finless porpoises in Ariake Sound and Tachibana Bay, Japan

Endangered Species Research, 2015
The narrow-ridged finless porpoise Neophocaena asiaeorientalis is a coastal cetacean that is threatened by various human activities. Bycatch mortality is a particular danger to the porpoise population in Ariake Sound and Tachibana Bay, Japan. To evaluate

Passive eDNA sampling facilitates biodiversity monitoring and rare species detection

Environment International
Environmental DNA (eDNA) technology has revolutionized biomonitoring, but challenges remain regarding water sample processing. The passive eDNA sampler (PEDS) represents a viable alternative to active, water filtration-based eDNA enrichment methods, but ...

Distribution analysis of the finless porpoises (Neophocaena sp.) and oceanic dolphins (Delphinidae) in the Korean Sea using environmental DNA.

PLoS ONE
Environmental DNA (eDNA) serves as a non-invasive tool for monitoring the presence of specific organisms in challenging or hard-to-access areas. We attempted non-invasive monitoring of Korean cetacean species by extracting eDNA from the western and ...

Social responses of travelling finless porpoises to boat traffic risk in Misumi West Port, Ariake Sound, Japan.

PLoS ONE, 2019
Anthropogenic effects have created various risks for wild animals. Boat traffic is one of the most fatal risks for marine mammals. Individual behavioral responses of cetaceans, including diving behavior such as changing swimming direction and lengthing ...

Yangtze Finless Porpoise Optimization Algorithm

To address the problems of existing swarm intelligence optimization algorithms, such as limited search information structure, reliance on mean statistics for group collaboration, and susceptibility to premature convergence, this paper proposes a novel swarm intelligence optimization method—the Yangtze Finless Porpoise Optimization Algorithm.

Effects of Freshwater Protected Areas on Survival of a Critically Endangered Cetacean

Conservation Letters
Evaluating the effectiveness of freshwater protected areas (FPAs) is crucial for improving their performance, yet evidence remains limited. Using remote sensing and field surveys from 2001 to 2017, we examined FPA coverage, their efficacy in preventing ...
