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.

Spontaneous neoplasms in harbour porpoises Phocoena phocoena [PDF]
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.

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.

Coming of age: - Do female harbour porpoises (Phocoena phocoena) from the North Sea and Baltic Sea have sufficient time to reproduce in a human influenced environment? [PDF]
PLoS ONE, 2017 The harbour porpoise is the only cetacean species native to German waters. Since human pressures are suggested to shorten their reproductive lifespan, basic knowledge on reproduction is strongly required.

Click communication in wild harbour porpoises (Phocoena phocoena). [PDF]
Sci Rep, 2018 AbstractSocial delphinids employ a vocal repertoire of clicks for echolocation and whistles for communication. Conversely, the less social and acoustically cryptic harbour porpoises (Phocoena phocoena) only produce narrow-band high-frequency (NBHF) clicks with properties that appear poorly suited for communication. Nevertheless, these small odontocetes

No serological evidence that harbour porpoises are additional hosts of influenza B viruses. [PDF]
PLoS ONE, 2014 Influenza A and B viruses circulate among humans causing epidemics almost annually. While various hosts for influenza A viruses exist, influenza B viruses have been detected only in humans and seals.

Anisakid nematode species identification in harbour porpoises (Phocoena phocoena) from the North Sea, Baltic Sea and North Atlantic using RFLP analysis [PDF]
International Journal for Parasitology: Parasites and Wildlife, 2020 Harbour porpoises (Phocoena phocoena) are the only native cetacean species in the German North and Baltic Seas and the final host of Anisakis (A.) simplex, which infects their first and second gastric compartments and may cause chronic ulcerative ...

Year-round spatiotemporal distribution of harbour porpoises within and around the Maryland wind energy area. [PDF]
PLoS ONE, 2017 Offshore windfarms provide renewable energy, but activities during the construction phase can affect marine mammals. To understand how the construction of an offshore windfarm in the Maryland Wind Energy Area (WEA) off Maryland, USA, might impact harbour

Harbour porpoises respond to recreational boats by speeding up and moving away from the boat path [PDF]
Ecology and EvolutionRecreational boats are common in many coastal waters, yet their effects on cetaceans and other sensitive marine species remain poorly understood. To address this knowledge gap, we used drone video footage recorded from a recreational boat to quantify how
