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…

Elliser, Cindy R.; Hessing, Sanne; MacIver, Katrina H.; Webber, Marc A.; Keener, William
Aquatic Mammals (2020)
...This short note documents instances of prey handling and consumption of large fish species along the West Coast of the United States (U.S.), including the Salish Sea (inland waters of…
Determination of Optimal Acoustic Passive Reflectors to Reduce Bycatch of Odontocetes in Gillnets
Kratzer, Isabella M. F.; Schäfer, Ingo; Stoltenberg, Arne; Chladek, Jérôme C.; Kindt-Larsen, Lotte; Larsen, Finn; Stepputtis, Daniel
Frontiers in Marine Science (2020)
The need to minimize bycatch of toothed whales (odontocetes) in gillnets has long been recognized, because they are often top predators and thus essential to ecosystem resilience. It is likely…
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)
Wang, Zhi-Tao; Akamatsu, Tomonari; Duan, Peng-Xiang; Zhou, Lu; Yuan, Jing; Li, Jiao; Lei, Pei-Yu; Chen, Yu-Wei; Yang, Yi-Ning; Wang, Ke-Xiong; Wang, Ding
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…
Habitat succession of the Yangtze finless porpoise in Poyang Lake under the changing hydrodynamic and feeding environment
Han, Yong; Sun, Zhiyu; Fang, Hongwei; Bai, Sen; Huang, Lei; He, Guojian
Ecological Modelling (2020)
Poyang Lake, located in the middle and lower reaches of the Yangtze River, is the largest freshwater lake in China and the most important habitat for the Yangtze finless porpoise.…
