Bartonella henselae in Porpoise Blood

Emerging Infectious Diseases, 2005
We report detection of Bartonella henselae DNA in blood samples from 2 harbor porpoises (Phocoena phocoena). By using real-time polymerase chain reaction, we directly amplified Bartonella species DNA from blood of a harbor porpoise stranded along the ...

Clicking in a killer whale habitat: narrow-band, high-frequency biosonar clicks of harbour porpoise (Phocoena phocoena) and Dall's porpoise (Phocoenoides dalli).

PLoS ONE, 2013
Odontocetes produce a range of different echolocation clicks but four groups in different families have converged on producing the same stereotyped narrow band high frequency (NBHF) click.

Indo-Pacific finless porpoises presence in response to pile driving on the Jinwan Offshore Wind Farm, China

Frontiers in Marine Science, 2023
The Jinwan Offshore Wind Farm project in the Pearl River Estuary (PRE) is a new stressor for the resident marine mammals there, especially for the Indo-Pacific finless porpoise.

Natural History and Exploitation of the Harbor Porpoise (Phocoena phocoena Linnaeus, 1758) during the Neolithic (ca. 4000–2000 cal. BC) in the Eastern Baltic Region

Animals, 2023
Compared with the history of seals in the Baltic Sea, the porpoise has received much less research attention. The harbor porpoise (Phocoena phocoena) has been quite rare in the eastern Baltic in recent centuries, but according to archaeological finds ...

Click emission in Dall's porpoise Phocoenoides dalli, focusing on physical properties of tissues. [PDF]

PLoS ONE, 2018
Dall's porpoise (Phocoenoides dalli) is one of most common North Pacific porpoise species, for which information on sound-emitting processes is limited.

Marine Mammal HiCUP: A High Current Underwater Platform for the Long-Term Monitoring of Fine-Scale Marine Mammal Behavior Around Tidal Turbines

Frontiers in Marine Science, 2022
Arrays of tidal turbines are being considered for tidally energetic coastal sites which can be important habitat for many species of marine mammal. Understanding risks to marine mammals from collisions with moving turbine blades must be overcome before ...

Water, water everywhere: environmental DNA can unlock population structure in elusive marine species [PDF]

Royal Society Open Science, 2018
Determining management units for natural populations is critical for effective conservation and management. However, collecting the requisite tissue samples for population genetic analyses remains the primary limiting factor for a number of marine ...

A real-time passive acoustic monitoring system to detect Yangtze finless porpoise clicks in Ganjiang River, China

Frontiers in Marine Science, 2022
Phocoenidae live in fresh, coastal waters where they often share a significant portion of their habitat with humans. As a result, local activities (e.g., coastal fisheries and shipments) cause underwater noise pollution and threaten their ecosystem.

Spatiotemporal relationships of threatened cetaceans and anthropogenic threats in the lower Yangtze system

Frontiers in Conservation Science, 2022
The impacts of fisheries interactions on cetaceans can be challenging to determine, often requiring multiple complementary investigative approaches. The Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis), one of the few Critically ...
