Comparing fish prey diversity for a critically endangered aquatic mammal in a reserve and the wild using eDNA metabarcoding

Scientific Reports, 2020
Using environmental DNA (eDNA) metabarcoding, we compared fish diversity in two distinct water bodies within the Yangtze River Basin with known populations of the critically endangered Yangtze finless porpoise (Neophocaena asiaeorientalis; YFP): the Tian-

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

Marine 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

Environmental 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

Environmental 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

Animal 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 ...

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

Molecular 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 ...

Fine-scaled habitat preference of the Yangtze finless porpoise in the Yangtze River

Abstract The Yangtze finless porpoise (Neophocaena asiaeorientalis) is critically endangered and suffered from extensive habitat loss and fragmentation. Knowledge on habitat preference of the Yangtze finless porpoise could assist finless porpoise and associated ecosystem-based conservation by knowing porpoises’ suitable environments and ...
