Aquatic resource conservation - The first Yangtze finless porpoise successfully born in captivity

open access: yes, 2005
Background. As the sole freshwater subspecies of finless porpoise (Neophocaena phocaenoides), the Yangtze finless porpoise (N. p. asiaeorientalis) lives only in the middle and lower reaches of the Yangtze River and its appended Poyang and Dongting Lakes.

Mating, Sociosexual, and Nursing Behavior of Wild East Asian Finless Porpoises in the Seto Inland Sea, Japan

open access: yesMarine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT The mating and sociosexual (nonconceptive) behaviors of narrow‐ridged finless porpoises (Neophocaena asiaeorientalis) have been extensively studied in captivity. However, such behaviors may differ significantly from those that have developed in wild populations. Drone videos captured the behaviors of wild finless porpoises including a total of

A Passive Environmental DNA Sampler for Aquatic Biodiversity Detection Tested in Marine Mesocosms

open access: yesEnvironmental DNA, Volume 7, Issue 5, September–October 2025.
ABSTRACT In aquatic ecosystems, environmental DNA (eDNA) can be collected from water samples to produce species inventories. One method for this is passive eDNA sampling, whose development for aquatic biodiversity monitoring is in its early stages. While several materials have been successfully tested for passive eDNA samplers (PEDS), methodological ...

Comparison of DNA Extraction Methods for Detecting the Sea Otter (Enhydra lutris ) in Marine Sediments

open access: yesEnvironmental DNA, Volume 7, Issue 5, September–October 2025.
Sedimentary DNA (sedDNA) holds promise for improving our understanding of historical species occurrences and contemporary biomonitoring. We evaluate the efficacy of sedDNA methods to detect the presence of a patchily distributed marine mammal, the sea otter. Using a targeted qPCR assay, we compared four sedDNA extraction techniques and two DNA cleaning

Prioritizing future evidence needs for marine and freshwater mammal conservation action

open access: yesAnimal Conservation, Volume 28, Issue 4, Page 542-552, August 2025.
To improve conservation practice, decisions should be informed by the available evidence on the effectiveness of conservation actions. Here, we review the comprehensiveness of this evidence base for marine and freshwater mammals. We assess the taxonomic and geographic coverage of the evidence base, identify biases and suggest priorities for future ...

A passive acoustic monitoring method applied to observation and group size estimation of finless porpoises

open access: yes, 2005
The present study aimed at determining the detection capabilities of an acoustic observation system to recognize porpoises under local riverine conditions and compare the results with sighting observations.

The Possible Effects of High Vessel Traffic on the Physiological Parameters of the Critically Endangered Yangtze Finless Porpoise (Neophocaena asiaeorientalis ssp. asiaeorientalis)

open access: yesFrontiers in Physiology, 2018
Background: Poyang is the largest freshwater lake in China, where the acoustic environment and space for the critically endangered Yangtze finless porpoises (YFPs) has been altered by heavy vessel traffic and dredging activities.

Evolutionary history and seascape genomics of Harbour porpoises (Phocoena phocoena) across environmental gradients in the North Atlantic and adjacent waters

open access: yesMolecular Ecology Resources, Volume 25, Issue 5, July 2025.
Abstract The Harbour porpoise (Phocoena phocoena) is a highly mobile cetacean species primarily occurring in coastal and shelf waters across the Northern hemisphere. It inhabits heterogeneous seascapes broadly varying in salinity and temperature. Here, we produced 74 whole genomes at intermediate coverage to study Harbour porpoise's evolutionary ...

Trace elements accumulation in the Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) - A threat to the endangered freshwater cetacean [PDF]

open access: yes, 2019
As a freshwater cetacean with a population of only approximately 1000 individuals, the Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) is threatened by water pollution.
