Journal of Sea Research (2015)
Along the Dutch shores hundreds of harbour porpoises Phocoena phocoena are stranded each year. A recurrent phenomenon in the Netherlands is a surge of strandings in late winter and early…
Synthetic communication signals influence wild harbour porpoise (Phocoena phocoena) behaviour
Culik, Boris; von Dorrien, Christian; Müller, Vailett; Conrad, Matthias
Bioacoustics (2015)
We used our novel and programmable Porpoise Alarm (PAL, patd.) to synthesize life-like, electronic harbour porpoise communication signals based on those described for captive animals. In the Little Belt, Denmark,…
Range-dependent flexibility in the acoustic field of view of echolocating porpoises (Phocoena phocoena)

eLife (2015)
Toothed whales use sonar to detect, locate, and track prey. They adjust emitted sound intensity, auditory sensitivity and click rate to target range, and terminate prey pursuits with high-repetition-rate, low-intensity…
Temporal changes in abundance of harbor porpoise (Phocoena phocoena) inhabiting the inland waters of Southeast Alaska
Dahlheim, Marilyn E.; Zerbini, Alexandre N.; Waite, Janice M.; Kennedy, Amy S.
Fishery Bulletin (2015)
Abundance of harbor porpoise (Phocoena phocoena) was estimated from data collected during vessel surveys conducted throughout the inland waters of Southeast Alaska. Line-transect methods were used during 18 seasonal surveys…

Harbor porpoise Phocoena phocoena strandings on the Dutch coast: No genetic structure, but evidence of inbreeding
van der Plas-Duivesteijn, Suzanne J.; Smit, Femmie J.L.; van Alphen, Jacques J.M.; Kraaijeveld, Ken
Journal of Sea Research (2015)
Conservation management in the North Sea is often motivated by the population size of marine mammals, like harbor porpoises Phocoena phocoena. In the Dutch part of the North Sea, sighting…
