Harbour porpoises respond to climate change. [PDF]
Ecol Evol, 2011 AbstractThe effects of climate change on marine ecosystems and in particular on marine top predators are difficult to assess due to, among other things, spatial variability, and lack of clear delineation of marine habitats. The banks of West Greenland are located in a climate sensitive area and are likely to elicit pronounced responses to oceanographic

Frontiers in Marine Science, 2020 Bycatch is a significant cause of population declines of marine megafauna globally. While numerous bycatch mitigation strategies exist, acoustic alarms, or pingers, are the most widely adopted strategy for small cetaceans.

Spontaneous neoplasms in harbour porpoises Phocoena phocoena
Diseases of Aquatic Organisms, 2022 Harbour porpoises are widely distributed in the North Atlantic and represent the most abundant cetacean species in the North and Baltic Seas. Spontaneous neoplasms are relatively rarely reported in cetaceans, and only little is known about neoplasia in harbour porpoises.

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.

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

Exposing the grey seal as a major predator of harbour porpoises. [PDF]
Proc Biol Sci, 2015 Harbour porpoises ( Phocoena phocoena ) stranding in large numbers around the southern North Sea with fatal, sharp-edged mutilations have spurred controversy among scientists, the fishing industry and conservationists, whose views about the likely cause differ.

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.

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.
