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

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.

Source of Aegean Sea harbour porpoises [PDF]
Marine Ecology Progress Series, 2003 Documented sightings of harbour porpoises in the Mediterranean are rare, although the species is common in the neighbouring North Atlantic and Black Sea. However, in the past 2 decades, 4 harbour porpoises Phocoena phocoena have been recorded in the northern Aegean Sea in the east- ern Mediterranean Basin. Samples were taken from 2 of these.

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

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.

Harbour porpoises (Phocoena phocoena) and wind farms: a case study in the Dutch North Sea [PDF]
, 2011 The rapid increase in development of offshore wind energy in European waters has raised concern for the possible environmental impacts of wind farms. We studied whether harbour porpoise occurrence has been affected by the presence of the Dutch offshore ...

High field metabolic rates of wild harbour porpoises [PDF]
Journal of Experimental Biology, 2018 ABSTRACTReliable estimates of field metabolic rates (FMRs) in wild animals are essential for quantifying their ecological roles, as well as for evaluating fitness consequences of anthropogenic disturbances. Yet, standard methods for measuring FMR are difficult to use on free-ranging cetaceans whose FMR may deviate substantially from scaling predictions

Silent porpoise: potential sleeping behaviour identified in wild harbour porpoises
Animal Behaviour, 2017 All animals sleep and it is essential for maintaining optimal brain function. However, cetaceans engage in the unusual practice of unihemispherical sleep, where only half of their brain sleeps at a time, due to their constant need for movement and breathing. Most studies of sleep in cetaceans have occurred in captivity.
