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…


Click reception in the harbor porpoise (Phocoena phocoena): Effects of electrode and contact transducer location on the auditory brainstem response

Mulsow, Jason; Finneran, James J.; Houser, Dorian S.; Nordstrom, Chad A.; Barrett-Lennard, Lance G.; Burkard, Robert F.
The Journal of the Acoustical Society of America (2018)

Unlike terrestrial mammals that have unambiguous aerial sound transmission pathways via the outer ear and tympanum, sound reception pathways in most odontocetes are not well understood. Recent studies have used…


Plastic ingestion by harbour porpoises Phocoena phocoena in the Netherlands: Establishing a standardised method

van Franeker, Jan A.; Bravo Rebolledo, Elisa L.; Hesse, Eileen; IJsseldijk, Lonneke L.; Kühn, Susanne; Leopold, Mardik; Mielke, Lara
Ambio (2018)

Stomach contents of harbour porpoises (Phocoena phocoena) collected in the Netherlands between 2003 and 2013 were inspected for the presence of plastic and other man-made litter. In 654 stomach samples…


Basin-scale distribution of harbour porpoises in the Baltic Sea provides basis for effective conservation actions

Carlén, Ida; Thomas, Len; Carlström, Julia; Amundin, Mats; Teilmann, Jonas; Tregenza, Nick; Tougaard, Jakob; Koblitz, Jens C.; Sveegaard, Signe; Wennerberg, Daniel; Loisa, Olli; Dähne, Michael; Brundiers, Katharina; Kosecka, Monika; Kyhn, Line Anker; Ljungqvist, Cinthia Tiberi; Pawliczka, Iwona; Koza, Radomil; Arciszewski, Bartlomiej; Galatius, Anders; Jabbusch, Martin; Laaksonlaita, Jussi; Niemi, Jussi; Lyytinen, Sami; Gallus, Anja; Benke, Harald; Blankett, Penina; Skóra, Krzysztof E.; Acevedo-Gutiérrez, Alejandro
Biological Conservation (2018)

Knowledge on spatial and seasonal distribution of species is crucial when designing protected areas and implementing management actions. The Baltic Proper harbour porpoise (Phocoena phocoena) population is critically endangered, and…
