The effects of marine traffic on the behaviour of Black Sea harbour porpoises (Phocoena phocoena relicta) within the Istanbul Strait, Turkey

PLoS ONE, 2017
Marine traffic is threatening cetaceans on a local and global scale. The Istanbul Strait is one of the busiest waterways, with up to 2,500 vessels present daily.

Highly Pathogenic Avian Influenza A(H5N1) Virus in a Harbor Porpoise, Sweden

Emerging Infectious Diseases, 2023
We found highly pathogenic avian influenza A(H5N1) virus clade 2.3.4.4b associated with meningoencephalitis in a stranded harbor porpoise (Phocoena phocoena). The virus was closely related to strains responsible for a concurrent avian influenza outbreak

Causes of Death and Pathological Findings in Stranded Harbour Porpoises (Phocoena phocoena) from Swedish Waters

Animals, 2022
Harbour porpoises (Phocoena phocoena) are useful indicators of the health of their wild populations and marine ecosystems, yet their elusive nature makes studying them in their natural environment challenging.

Whale lice (Isocyamus deltobranchium & Isocyamus delphinii; Cyamidae) prevalence in odontocetes off the German and Dutch coasts – morphological and molecular characterization and health implications

International Journal for Parasitology: Parasites and Wildlife, 2021
Whale lice (Cyamidae; Amphipoda) are ectoparasitic crustaceans adapted to the marine environment with cetaceans as their host. There are few reports of cyamids occurring in odontocetes from the North Sea, and long-term studies are lacking.

After the bite: bacterial transmission from grey seals (Halichoerus grypus) to harbour porpoises (Phocoena phocoena) [PDF]

Royal Society Open Science, 2020
Recent population growth of the harbour porpoise (Phocoena phocoena), grey seal (Halichoerus grypus) and common seal (Phoca vitulina) in the North Sea has increased potential interaction between these species.

Harbour porpoises Phocoena phocoena in the eastern Scheldt: a resident stock or trapped by a storm surge barrier? [PDF]

PLoS ONE, 2013
Coastal protection measures are planned and executed worldwide to combat the effects of global warming and climate change, in particular the acceleration of sea level rise, higher storm surge flooding and extensive coastal inundation. The extent to which

Bite injuries of grey seals (Halichoerus grypus) on harbour porpoises (Phocoena phocoena). [PDF]

PLoS ONE, 2014
Bite-like skin lesions on harbour porpoises (Phocoena phocoena) have been suspected to be caused by grey seals (Halichoerus grypus), and a few field observations have been reported.

Diving on damage—the muscle transcriptome of parasitic infested harbor porpoises (Phocoena phocoena) hints at oxidative stress but not hypoxia

Frontiers in Marine Science, 2023
The only native cetacean in German waters, the harbor porpoise (Phocoena phocoena), is impacted by numerous pathological lesions in the respiratory tract mainly caused by parasites or bacteria.

Underwater Noise Level Recordings from a Water Intake Pontoon and Possible Impacts on Yangtze Finless Porpoises in a Natural Reserve

Animals, 2022
Underwater noise pollution caused by human activities may affect freshwater cetaceans to different degrees. To analyze the impacts of water intake pontoons on Yangtze finless porpoises (Neophocaena asiaeorientalis), this study collected underwater noise ...
