The click production of captive Yangtze finless porpoises (Neophocaena asiaeorientalis asiaorientalis) is influenced by social and environmental factors

Serres, Agathe; Xu, Chen; Hao, Yujiang; Wang, Ding
Animals (2021)

Yangtze finless porpoises use high-frequency clicks to navigate, forage, and communicate. The way in which click production may vary depending on social or environmental context has never been investigated. A…


High resolution three-dimensional beam radiation pattern of harbour porpoise clicks with implications for passive acoustic monitoring

Macaulay, Jamie D. J.; Malinka, Chloe E.; Gillespie, Douglas; Madsen, Peter T.
The Journal of the Acoustical Society of America (2020)

The source properties and radiation patterns of animal vocalisations define, along with propagation and noise conditions, the active space in which these vocalisations can be detected by conspecifics, predators, prey,…


High rates of vessel noise disrupt foraging in wild harbour porpoises (Phocoena phocoena)

Wisniewska, Danuta Maria; Johnson, Mark; Teilmann, Jonas; Siebert, Ursula; Galatius, Anders; Dietz, Rune; Madsen, Peter Teglberg
Proceedings of the Royal Society B: Biological Sciences (2018)

Shipping is the dominant marine anthropogenic noise source in the world's oceans, yet we know little about vessel encounter rates, exposure levels and behavioural reactions for cetaceans in the wild,…


Acoustic monitoring reveals the times and tides of harbor porpoise (Phocoena phocoena) distribution off central Oregon, U.S.A.

Holdman, Amanda K.; Haxel, Joseph H.; Klinck, Holger; Torres, Leigh G.
Marine Mammal Science (2018)

Harbor porpoises (Phocoena phocoena) are commonly observed in Oregon's nearshore marine environment yet knowledge of their ecosystem use and behavior remains limited, generating concerns for potential impacts on this species…


Bubble curtains attenuate noise from offshore wind farm construction and reduce temporary habitat loss for harbour porpoises

Dähne, M.; Tougaard, J.; Carstensen, J.; Rose, A.; Nabe-Nielsen, J.
Marine Ecology Progress Series (2017)

Effects of constructing the DanTysk offshore wind farm (German Bight, 80 turbines, 6 m diameter foundations) were studied by passive acoustic monitoring of pile-driving noise and harbour porpoise Phocoena phocoena…


Time and tide: Seasonal, diel and tidal rhythms in Wadden Sea harbour porpoises (Phocoena phocoena)

Zein, Beate; Woelfing, Benno; Dähne, Michael; Schaffeld, Tobias; Ludwig, Stefan; Rye, Jacob Hansen; Baltzer, Johannes; Ruser, Andreas; Siebert, Ursula
PLOS ONE (2019)

Odontocetes have evolved a rich diversity of prey- and habitat-specific foraging strategies, which allows them to feed opportunistically on locally and temporally abundant prey. While habitat-specific foraging strategies have been…
