Aquatic Mammals (2012)
In September 2011, two harbour porpoises (Phocoena phocoena) presenting extensive traumatic lesions washed ashore in Belgium. Similar lesions, with large parts of skin and blubber missing, had not been recorded…
First records of anomalously white harbour porpoises (Phocoena phocoena) in the Turkish seas with a global review

Hystrix - The Italian Journal of Mammalogy (2012)
Three anomalously white harbour porpoises (Phocoena phocoena) were reported from Turkish Seas. One of them was bycaught on 19 June 2011 in bottom gill nets off the eastern coast of…
Negative long term effects on harbour porpoises from a large scale offshore wind farm in the Baltic – evidence of slow recovery
Teilmann, Jonas; Carstensen, Jacob
Environmental Research Letters (2012)
Offshore wind farms constitute a new and fast growing industry all over the world. This study investigates the long term impact on harbour porpoises, Phocoena phocoena, for more than 10…
Swimming patterns of wild harbour porpoises Phocoena phocoena show detection and avoidance of gillnets at very long ranges
Nielsen, T.P.; Wahlberg, M.; Heikkilä, S.; Jensen, M.; Sabinsky, P.; Dabelsteen, T.
Marine Ecology Progress Series (2012)
Harbour porpoises Phocoena phocoena are unintentionally caught in gillnets. Although the effectiveness of by-catch mitigation measures has been evaluated many times, only a few studies have investigated the behavioural patterns…
Spatial interactions between marine predators and their prey: Herring abundance as a driver for the distributions of mackerel and harbour porpoise
Sveegaard, S.; Nabe-Nielsen, J.; Stæhr, K. J.; Jensen, T. F.; Mouritsen, K. N.; Teilmann, J.
Marine Ecology Progress Series (2012)
The distribution of marine predators is tightly coupled with that of their prey, and may also be affected by interactions between competing predators. In order to adopt an ecosystem approach…
Asymmetry and dynamics of a narrow sonar beam in an echolocating harbor porpoise
Koblitz, Jens C.; Wahlberg, Magnus; Stilz, Peter; Madsen, Peter T.; Beedholm, Kristian; Schnitzler, Hans-Ulrich
The Journal of the Acoustical Society of America (2012)
A key component in the operation of a biosonar system is the radiation of sound energy from the sound producing head structures of toothed whales and microbats. The current view…
Feeding ecology of harbour porpoises: Stable isotope analysis of carbon and nitrogen in muscle and bone
Jansen, Okka E.; Aarts, Geert M.; Das, Krishna; Lepoint, Gilles; Michel, Loïc; Reijnders, Peter J.H.
Marine Biology Research (2012)
Harbour porpoises are the most common small cetaceans in the North Sea and Dutch coastal waters. To study their trophic level and feeding location, stable carbon and nitrogen isotope ratios…
