Detailed knowledge on habitat use by marine mammals is critical for understanding their ecological role and for adequate management. Here, we assess the habitat use patterns of thirteen species of…


Levels of polychlorinated biphenyls are still associated with toxic effects in harbor porpoises (Phocoena phocoena) despite having fallen below proposed toxicity thresholds

Williams, Rosie; ten Doeschate, Mariel; Curnick, David J.; Brownlow, Andrew; Barber, Jonathan L.; Davison, Nicholas J.; Deaville, Robert; Perkins, Matthew; Jepson, Paul D.; Jobling, Susan
Environmental Science & Technology (2020)

Polychlorinated biphenyls (PCBs) are toxic, persistent, and lipophilic chemical compounds that accumulate to high levels in harbor porpoises (Phocoena phocoena) and other cetaceans. It is important to monitor PCBs in…


Harbor porpoise (Phocoena phocoena) reaction to a 3D seismic airgun survey in the North Sea

Sarnocińska, Joanna; Teilmann, Jonas; Balle, Jeppe Dalgaard; van Beest, Floris M.; Delefosse, Matthieu; Tougaard, Jakob
Frontiers in Marine Science (2020)

The most common cetacean in the North Sea is the harbor porpoise (Phocoena phocoena). Underwater noise is increasingly recognized as a source of impact on the marine environment and seismic…


Modelling fine-scale distribution and relative abundance of harbour porpoises in the Southern Bight of the North Sea using platform-of-opportunity data

Bouveroux, Thibaut; Waggitt, James J.; Belhadjer, Anissa; Cazenave, Pierre W.; Evans, Peter G.H.; Kiszka, Jeremy J.
Journal of the Marine Biological Association of the United Kingdom (2020)

Over the last 25 years, the harbour porpoise (Phocoena phocoena) has made a significant return to the Southern Bight of the North Sea and the English Channel due to a…


Effects of multiple exposures to pile driving noise on harbor porpoise hearing during simulated flights—An evaluation tool

Schaffeld, Tobias; Schnitzler, Joseph G.; Ruser, Andreas; Woelfing, Benno; Baltzer, Johannes; Siebert, Ursula
The Journal of the Acoustical Society of America (2020)

Exploitation of renewable energy from offshore wind farms is substantially increasing worldwide. The majority of wind turbines are bottom mounted, causing high levels of impulsive noise during construction. To prevent…


Modeling of the near to far acoustic fields of an echolocating bottlenose dolphin and harbor porpoise

Wei, Chong; Au, Whitlow W. L.; Ketten, Darlene R.
The Journal of the Acoustical Society of America (2020)

Echolocation signals emitted by odontocetes can be roughly classified into three broad categories: broadband echolocation signals, narrowband high-frequency echolocation signals, and frequency modulated clicks. Previous measurements of broadband echolocation signal…


Immune responses of the critically endangered Yangtze finless porpoises (Neophocaena asiaeorientalis ssp. asiaeorientalis) to escalating anthropogenic stressors in the wild and seminatural environments

Nabi, Ghulam; Li, Ying; McLaughlin, Richard W.; Mei, Zhigang; Wang, Kexiong; Hao, Yujiang; Zheng, Jinsong; Wang, Ding
Frontiers in Physiology (2020)

Increasing anthropogenic stressors are potential threats to biodiversity conservation and management of Yangtze finless porpoises (YFPs). The objective of this study was to indirectly compare the habitat quality of a…


Underwater noise pollution in China’s Yangtze River critically endangers Yangtze finless porpoises (Neophocaena asiaeorientalis asiaeorientalis)

Environmental Pollution (2020)

Underwater sound plays an important role in some critical life functions of many aquatic animals. Underwater noise pollution has received relatively more attention in ocean systems. However, little attention has…


Using passive acoustic monitoring to investigate the occurrence of cetaceans in a protected marine area in northwest Ireland

Todd, Nicole R. E.; Cronin, Michelle; Luck, Cian; Bennison, Ashley; Jessopp, Mark; Kavanagh, Ailbhe S.
Estuarine, Coastal and Shelf Science (2020)

Under the EU Habitats Directive, cetacean species must be maintained at favourable conservation status in European waters. Whether this is achieved via protected area designation, curtailment of activities such as…
