The Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis), has experienced rapid declines in recent decades. We estimate its abundance based on surveys conducted between November and December 2017 in the main-stem…

Mycotic infections in free-ranging harbor porpoises (Phocoena phocoena)

Kapetanou, Athanasia; IJsseldijk, Lonneke L.; Willems, Dorien S.; Broens, Els M.; Everaarts, Eligius; Buil, Jochem B.; Verweij, Paul E.; Kik, Marja J. L.; Gröne, Andrea
Frontiers in Marine Science (2020)

Studies on the occurrence of fungal communities in the marine environment are still scarce, but mycotic infections in cetaceans are increasingly reported. Fungal disease following infection with Aspergillus species is…

The use of seal scarers as a protective mitigation measure can induce hearing impairment in harbour porpoises

Schaffeld, Tobias; Ruser, Andreas; Woelfing, Benno; Baltzer, Johannes; Kristensen, Jakob H.; Larsson, Josefin; Schnitzler, Joseph G.; Siebert, Ursula
The Journal of the Acoustical Society of America (2019)

Acoustic deterrent devices (ADDs) are used to deter seals from aquacultures but exposure of harbour porpoises (Phocoena phocoena) occurs as a side-effect. At construction sites, by contrast, ADDs are used…

The impact of marine vessels on the presence and behaviour of harbour porpoise (Phocoena phocoena) in the waters off Berry Head, Brixham (South West England)

Roberts, Laura; Collier, Stuart; Law, Samantha; Gaion, Andrea
Ocean & Coastal Management (2019)

Harbour porpoise (Phocoena phocoena) are protected in the UK by the Wildlife and Countryside Act (1981). Understanding the impact of anthropogenic pressures is fundamental for effective protection under this act…
