Complete Mitochondrial Genome Analysis Reveals Genetic Diversity in the Narrow–Ridged Finless Porpoise (Neophocaena asiaeorientalis) Across East Asian Waters

Ecology and Evolution, Volume 15, Issue 4, April 2025.
The narrow‐ridged finless porpoise (Neophocaena asiaeorientalis Pilleri & Gihr, 1972) is one of the most endangered cetacean species inhabiting East Asian waters. Complete mitogenome analysis offers accurate phylogenetic insights; however, complete mitogenome sequences for the narrow‐ridged finless porpoise have so far been restricted to specific ...

Diving behaviour of freshwater finless porpoises (Neophocaena phocaenoides) in an oxbow of the Yangtze River, China

, 2002
Dive-depth and swim-speed of a juvenile and an adult free-ranging, Yangtze finless porpoises (Neophocaena phocaenoides) were observed using velocity-time-depth recorders in an oxbow of the Yangtze River. In total, 8222 individual dives were recorded over

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

Ecology and Evolution
Numerous 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.

A quantitative assessment of dominance relations among the captive Yangtze finless porpoises (Neophocaena Phocaenoides Asiaeorientalis)

, 2007
This study was designed to investigate whether dominance relations exist among captive Yangtze finless porpoises ( Neophocaena phocaenoides asiaeorientalis) and how the relations establish, as well as how porpoises maintain the relations stable.

Density estimation of Yangtze finless porpoises using passive acoustic sensors and automated click train detection

, 2010
A method is presented to estimate the density of finless porpoises using stationed passive acoustic monitoring. The number of click trains detected by stereo acoustic data loggers (A-tag) was converted to an estimate of the density of porpoises.

Evoked-potential audiogram of the Yangtze finless porpoise Neophocaena phocaenoides asiaeorientalis (L)

, 2005
Evoked-potential audiograms were obtained in two (one male and one female) Yangtze finless porpoises, Neophocaena phocaenoides asiaseorientalis. Sinusoidal amplitude-modulated 20-ms tone bursts were used as probes with recording envelope-following evoked

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.
