Underwater Noise Level Recordings from a Water Intake Pontoon and Possible Impacts on Yangtze Finless Porpoises in a Natural Reserve

open access: yesAnimals, 2022
Underwater noise pollution caused by human activities may affect freshwater cetaceans to different degrees. To analyze the impacts of water intake pontoons on Yangtze finless porpoises (Neophocaena asiaeorientalis), this study collected underwater noise ...

Predicting ecology and hearing sensitivities in Parapontoporia—An extinct long‐snouted dolphin

open access: yesThe Anatomical Record, Volume 309, Issue 4, Page 853-863, April 2026.
Abstract Analyses of the cetacean (whale and dolphin) inner ear provide glimpses into the ecology and evolution of extinct and extant groups. The paleoecology of the long‐snouted odontocete (toothed whale) group, Parapontoporia, is primarily marine with its depositional context also suggesting freshwater tolerance.

Seasonal and Diurnal Patterns of Harbor Porpoise (Phocoena phocoena) Behavior and the Disruptive Effects of Vessel Presence in a High‐Traffic Coastal Habitat

open access: yesMarine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Chronic anthropogenic activity is an ongoing threat to the marine environment and presents unique challenges in shallow, coastal habitats where harbor porpoises reside. Harbor porpoises have high metabolic needs and are highly susceptible to negative environmental factors; however, no long‐term studies have been conducted on wild populations ...

Sound Reception in the Yangtze Finless Porpoise and Its Extension to a Biomimetic Receptor

open access: yesBiomimetics, 2023
Sound reception was investigated in the Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis) at its most sensitive frequency. The computed tomography scanning, sound speed, and density results were used to develop a three-dimensional ...

Severe Hearing Loss in the World's First Successfully Captive‐Born Yangtze Finless Porpoise: Impact of High Underwater Sound Exposure and Congenital Hearing Disorders

open access: yesIntegrative Zoology, Volume 21, Issue 2, Page 331-342, March 2026.
The audiogram of the world's first successfully captive‐born Yangtze finless porpoise was on average 40 dB higher than conspecifics. Congenital hearing disorders and noise exposure may be the primary cause of porpoise's hearing loss. ABSTRACT Aquariums globally have seen significant growth in recent decades.

Investigating the distribution of the Yangtze finless porpoise in the Yangtze River using environmental DNA.

open access: yesPLoS ONE, 2019
Determining the distribution of the Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis, YFP) in the Yangtze River has to date relied on traditional visual and counting methods, but such field surveys are time-consuming and expensive ...

Integrating Local Ecological Knowledge and Fishing Effort Data to Inform Bycatch Management of Threatened Marine Fauna in Small‐Scale Fisheries

open access: yesDiversity and Distributions, Volume 32, Issue 3, March 2026.
ABSTRACT Aim To examine the utility of local ecological knowledge (LEK) and fishing effort data in revealing bycatch patterns of marine threatened species in small‐scale fisheries to inform their conservation and management. Location Northern Haizhou Bay, China (35° to 37° N, 119° to 122° E).

Validation of aerial photogrammetry methods to measure body size, condition and mass in small cetaceans

open access: yesThe Journal of Physiology, Volume 604, Issue 5, Page 1788-1808, 1 March 2026.
Abstract figure legend Unoccupied aerial vehicle (UAV)‐based photogrammetry provides measurements equivalent to traditional hand measurements in bottlenose dolphins. Mass estimates derived from UAV measurements closely match the true body mass of live individuals.

Do Marine Mammals Diversify More Slowly Than Non‐Marine Mammals?

open access: yesJournal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim Species richness is generally lower in marine than in terrestrial ecosystems, but the reasons behind this disparity remain unclear. This study examines whether marine mammals diversify at a slower pace than their non‐marine counterparts, aiming to shed light on the factors explaining potential diversification differences among them ...
