A European melting pot of harbour porpoise in the French Atlantic coasts inferred from mitochondrial and nuclear data. [PDF]

PLoS ONE, 2012
Field surveys have reported a global shift in harbour porpoise distribution in European waters during the last 15 years, including a return to the Atlantic coasts of France.

Hardly seen, often heard: acoustic presence of harbour porpoises (Phocoena phocoena) in one of the most urbanised estuaries in the world

Frontiers in Marine Science, 2023
The New York-New Jersey (NY-NJ) Harbour Estuary and surrounding waters support the largest port along the U.S. East Coast, commercial and recreational fishing, and a burgeoning offshore wind energy industry.

Blast injury on harbour porpoises (Phocoena phocoena) from the Baltic Sea after explosions of deposits of World War II ammunition

Environment International, 2022
Harbour porpoises are under pressure from increasing human activities. This includes the detonation of ammunition that was dumped in large amounts into the sea during and after World War II.

Screening for Influenza and Morbillivirus in Seals and Porpoises in the Baltic and North Sea

Pathogens, 2023
Historically, the seals and harbour porpoises of the Baltic Sea and North Sea have been subjected to hunting, chemical pollutants and repeated mass mortalities, leading to significant population fluctuations. Despite the conservation implications and the

Interfollicular Fibrosis in the Thyroid of the Harbour Porpoise: An Endocrine Disruption? [PDF]

Archives of Environmental Contamination and Toxicology, 2006
Previous studies have described high levels of polychlorobiphenyls (PCB), polybrominated diphenylether (PBDE), toxaphene, p,p'-dichlorodiphenyltrichloroethane (DDT), and p,p'-dichlorodiphenyldichloroethylene (DDE) in the blubber of the harbour porpoise from the North Sea raising the question of a potential endocrine disruption in this species.

Environmental drivers of harbour porpoise fine-scale movements [PDF]

Marine Biology, 2018
Quantifying intraspecific variation in movement behaviour of marine predators and the underlying environmental drivers is important to inform conservation management of protected species. Here, we provide the first empirical data on fine-scale movements of free-ranging harbour porpoises (Phocoena phocoena) in their natural habitat.

Echolocation activity of harbour porpoises, Phocoena phocoena, shows seasonal artificial reef attraction despite elevated noise levels close to oil and gas platforms

Ecological Solutions and Evidence, 2021
Harbour porpoises frequently alter their behaviour in response to underwater sound from shipping, seismic surveys, drilling and marine renewables. Less well understood is the response of porpoises to sounds emitted from oil and gas (O&G) platforms during

Assessment of the bycatch level for the Black Sea harbour porpoise in the light of new data on population abundance

Frontiers in Marine Science, 2023
Incidental catch in fishing gear (often known as bycatch) is a major mortality factor for the Black Sea harbour porpoise (Phocoena phocoena relicta), an endemic subspecies listed as Endangered in the IUCN Red List.

Range-dependent flexibility in the acoustic field of view of echolocating porpoises (Phocoena phocoena) [PDF]

, 2015
Funding: Det Frie Forskningsrad (MJ)Toothed whales use sonar to detect, locate, and track prey. They adjust emitted sound intensity, auditory sensitivity and click rate to target range, and terminate prey pursuits with high-repetition-rate, low-intensity

Echolocation by the harbour porpoise: life in coastal waters [PDF]

Frontiers in Physiology, 2013
The harbor porpoise is one of the smallest and most widely spread of all toothed whales. They are found abundantly in coastal waters all around the northern hemisphere. They are among the 11 species known to use high frequency sonar of relative narrow bandwidth.
