The nightscape of the Arctic winter shapes the diving behavior of a marine predator

Scientific Reports
Predator–prey interactions in marine ecosystems are dynamically influenced by light, as demonstrated by diel vertical migrations of low-trophic level organisms.

Prevalence, impact and molecular characterisation of parasites in harbour porpoises and harbour seals [PDF]

, 2009
Parasitismus bei Wildtieren ist allgegenwärtig, zur Dynamik von Parasiteninfektionen und damit assoziierten Erkrankungen in marinen Säugetieren ist jedoch wenig bekannt. In dieser Arbeit wurde die Parasitenfauna von Schweinswal (Phocoena phocoena) und Seehund (Phoca vitulina) charakterisiert und ihr Einfluss auf den Gesundheitszustand der Wirte ...

[Polychlorinated naphthalenes in Harbour porpoises Phocoena phocoena].

Roczniki Panstwowego Zakladu Higieny, 1997
Concentration and composition of chloronaphthalenes (PCNs) were determined in blubber of two male and two female porpoises from the Gulf of Gdańsk. Porpoises examined died in the fishing nets in 1992. Polychlorinated naphthalenes were determined using capillary gas chromatography and high resolution mass spectrometry (HRGC/HRMS) after nondestructive ...

Reduction of harbour porpoise bycatch in protected areas

The overall purpose of the project was to investigate how the behavior of harbor porpoises is affected in relation to acoustic alarms, so called pingers. In the project, the main focus was on studies of the effective range of pingers, their long-term effects, how porpoises reacts to the pinger signals and models of pingers effect on porpoises ...

The feasibility of tagging harbour porpoises in Dutch waters

, 2016
The tagging of harbour porpoise (Phocoena phocosena) with satellite-linked locators or time-depth recorders allows researchers to obtain data on the behaviour and ecology of this species. It is also a valuable tool to investigate the impact of human activities on individuals and a number of recent publications have highlighted that for porpoises in ...

Evolutionary genomics of Harbour porpoises (Phocoena phocoena)

The Harbour porpoise (Phocoena phocoena) is a highly mobile cetacean species occurring in heterogeneous seascapes across the Northern hemisphere. I have produced 84 whole genomes which were used for population structure, demographic history and genotype-environment association analyses.

Ecology and Conservation of the Baltic Proper Harbour Porpoise

, 2022
The Baltic Proper harbour porpoise (Phocoena phocoena) population is listed by IUCN as Critically Endangered, but conservation action has been lacking for decades, partly due to very limited knowledge on important ecological parameters such as distribution range and abundance.
