Hematologic and biochemical differences between two free ranging Yangtze finless porpoise populations: The implications of habitat.

PLoS ONE, 2017
The goals of this study were to compare the serum chemistry and hematology values of wild and semi-natural free-ranging Yangtze Finless Porpoises (Neophocaena asiaeorientalis ssp. asiaeorientalis) populations and to ascertain how these values change with

First Comprehensive Study of Telomere Length Measured by Southern Blot Hybridization and Oxidative Stress Across 12 Captive Marine Mammal Species

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Telomeres, repetitive nucleotide sequences at chromosome ends, shorten with oxidative damage and cell replication, and are increasingly used as biomarkers of stress and physiological state. Despite this potential, telomere length (TL) in marine mammals has been measured using Southern blot hybridization in only a few cases, often from ...

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

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

Improve Carbon Budget Assessment in Floodplain Wetlands Using Hydrodynamic and Integrated Machine Learning Models

Water Resources Research, Volume 61, Issue 10, October 2025.
Abstract Floodplain wetlands play a crucial role in the global carbon cycle, yet the spatiotemporal variation of carbon flux in floodplain wetlands remains poorly understood due to complex hydrological processes. Here, we present an integrated framework to upscale net ecosystem CO2 exchange (NEE) in floodplain wetlands by combining eddy covariance ...

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 ...

Feeding Habits and Consumption by Finless Porpoises (Neophocaena asiaeorientalis) in the Yellow Sea

Korean Journal of Fisheries and Aquatic Sciences, 2011
We investigated the stomach contents of finless porpoises collected in the Yellow Sea. Prey organisms in the stomachs of 109 finless porpoises were identified as 11 species of fish, 8 species of shrimp and 4 species of cephalopod. Index of Relative Importance analysis revealed that the porpoises fed mainly on the Japanese sand shrimp (Crangon affinis).

Two Strategies for Researching the Endangered Yangtze Finless Porpoises Suggest Data‐Poor Areas Are Worthy of Greater Conservation Efforts

Ecology and Evolution, Volume 15, Issue 7, July 2025.
Two strategies were used to assess the abundance and distribution of Yangtze finless porpoises in the Jingjiang section of the Yangtze River to make up for the lack of knowledge about this area. These results provide support for the management and conservation of finless porpoises.
