Out of sight, out of mind: How conservation is failing European porpoises

Carlén, Ida; Nunny, Laetitia; Simmonds, Mark P.
Frontiers in Marine Science (2021)

The conservation of harbor porpoises (Phocoena phocoena) appears to be failing in Europe. There are particular concerns about this species in the Baltic Proper, Black, and Mediterranean Seas, as well…


Assessing harbour porpoise populations in south-west Wales, data issues and implications for conservation and management

The UK Government was recently criticised for failing to fulfil its obligations under the Habitats Directive in respect of designating protected areas for Harbour Porpoise Phocoena phocoena. At the centre…


Assessing the effects of banana pingers as a bycatch mitigation device for harbour porpoises (Phocoena phocoena)

Bycatch is a significant cause of population declines of marine megafauna globally. While numerous bycatch mitigation strategies exist, acoustic alarms, or pingers, are the most widely adopted strategy for small…


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…


Assessment of beach-cast cetaceans in Pakistan: Implications for conservation and management

Gore, M. A.; Culloch, R. M.; Gray, H. W. I.; Hoelzel, R.; Lockyer, C.; Kiani, M. S.; Waqas, U.; Hussain, B.; Rahim, A.; Shah, A.; Ormond, R. F. G.
Journal of Cetacean Research and Management (2017)

Until recently, little was known about the distribution and species occurrence of marine cetaceans in Pakistani waters, an area which needed to be addressed exigently given its inclusion in the…


Genetic footprint of population fragmentation and contemporary collapse in a freshwater cetacean

Chen, Minmin; Fontaine, Michael C.; Ben Chehida, Yacine; Zheng, Jinsong; Labbé, Frédéric; Mei, Zhigang; Hao, Yujiang; Wang, Kexiong; Wu, Min; Zhao, Qingzhong; Wang, Ding
Scientific Reports (2017)

Understanding demographic trends and patterns of gene flow in an endangered species is crucial for devising conservation strategies. Here, we examined the extent of population structure and recent evolution of…


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,…
