Lutra (2018)
It is a tradition that regular overviews are published of strandings of cetaceans. The last overviews for Belgium covered the period 1975 to 1989 and 1990 to 1994. This overview…
The possible effects of high vessel traffic on the physiological parameters of the critically endangered Yangtze finless porpoise (Neophocaena asiaeorientalis ssp. asiaeorientalis)
Nabi, Ghulam; Hao, Yujiang; McLaughlin, Richard William; Wang, Ding
Frontiers in Physiology (2018)
Poyang is the largest freshwater lake in China, where the acoustic environment and space for the critically endangered Yangtze finless porpoises (YFPs) has been altered by heavy vessel traffic and…
Environmental drivers of harbour porpoise fine-scale movements
van Beest, Floris M.; Teilmann, Jonas; Dietz, Rune; Galatius, Anders; Mikkelsen, Lonnie; Stalder, Dominique; Sveegaard, Signe; Nabe-Nielsen, Jacob
Marine Biology (2018)
Quantifying intraspecific variation in movement behaviour of marine predators and the underlying environmental drivers is important to inform conservation management of protected species. Here, we provide the first empirical data…
Noise affects porpoise click detections – the magnitude of the effect depends on logger type and detection filter settings
Clausen, Karin Tubbert; Tougaard, Jakob; Carstensen, Jacob; Delefosse, Matthieu; Teilmann, Jonas
Bioacoustics (2018)
Automatic click detectors and full-bandwidth sound recorders are widely used in passive acoustic monitoring of small cetaceans. Detection of these signals depends on a variety of factors, including signal to…
About stranding and accidentally caught cetaceans in the Black Sea: Death reasons, feeding characteristics and pregnancy status
Bilgin, Sabri; Onay, Hatice; Köse, Ozay; Yeşilçiçek, Tuncay
Türk Tarım ve Doğa Bilimleri Dergisi (2018)
This study was carried out to determine stranding levels, dead reasons and some reproduction features and diet of the Black Sea’ cetacean species (harbour porpoise, Phocoena phocoena and common dolphin,…
Cetacean stranding records along the Danish coastline: Records for the period 2008-2017 and a comparative review
Kinze, C. C.; Thøstesen, C. B.; Olsen, M. T.
Lutra (2018)
For the period 2008-2017, finds of stranded cetaceans along the Danish coastline are listed and reviewed in comparison to the preceding 40-year period (1968-2007). The harbour porpoise (Phocoena phocoena) was…
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,…
Crossing boundaries for cetacean conservation: Setting research priorities to guide management of harbour porpoises
IJsseldijk, Lonneke L.; ten Doeschate, Mariel T. I.; Davison, Nicholas J.; Gröne, Andrea; Brownlow, Andrew C.
Marine Policy (2018)
Effective management of natural resources involves a multidisciplinary perspective to address complex issues in data poor-environments. With mobile species that do not conform to human-defined borders a cross-boundary approach is…
Distribution and habitat use of a cryptic small cetacean, the Burmeister’s porpoise, monitored from a small-scale fishery platform
Clay, Thomas A.; Mangel, Jeffrey C.; Alfaro-Shigueto, Joanna; Hodgson, David J.; Godley, Brendan J.
Frontiers in Marine Science (2018)
There is widespread evidence that small-scale fisheries (SSF) bycatch threatens many populations of small cetaceans, yet conservation efforts are often limited by a lack of basic knowledge regarding their abundance,…
Raising your voice: Evolution of narrow-band high-frequency signals in toothed whales (Odontoceti)
Galatius, Anders; Olsen, Morten Tange; Steeman, Mette Elstrup; Racicot, Rachel A.; Bradshaw, Catherine D; Kyhn, Line A.; Miller, Lee A.
Biological Journal of the Linnean Society (2018)
Cetaceans use sound for communication, navigation and finding prey. Most extant odontocetes produce broadband (BB) biosonar clicks covering frequency ranges from tens of kilohertz to 150–170 kHz. In contrast, the…
