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…
Contextual impacts on individual and synchronous breathing rate variations in three captive odontocete groups
Serres, Agathe; Hao, Yujiang; Wang, Ding
Zoo Biology (2020)
Breathing rates are often collected both in the wild and in captivity to inform on cetaceans' internal state. However, few studies have investigated the effect of various factors on this…
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…
Harbor porpoises (Phocoena phocoena vomerina) catching and handling large fish on the U.S. west coast
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…
After the bite: Bacterial transmission from grey seals (Halichoerus grypus) to harbour porpoises (Phocoena phocoena)
Gilbert, Maarten J.; IJsseldijk, Lonneke L.; Rubio-García, Ana; Gröne, Andrea; Duim, Birgitta; Rossen, John; Zomer, Aldert L.; Wagenaar, Jaap A.
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. Grey…
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…
