Reproductive failure in mammals due to exposure to polychlorinated biphenyls (PCBs) can occur either through endocrine disrupting effects or via immunosuppression and increased disease risk. To investigate further, full necropsies…
Differences in skull size of harbour porpoises, Phocoena phocoena (Cetacea), in the Sea of Azov and the Black Sea: evidence for different morphotypes and populations
Goldin, P. E.; Vishnyakova, K. A.
Vestnik Zoologii (2015)
There are two porpoise stocks in the northern Black Sea: the north-western (Odessa Gulf) and northeastern (Crimean and Caucasian waters); in addition, another stock is in the Sea of Azov.…
Organophosphorus flame retardants (PFRs) and plasticisers in harbour porpoises (Phocoena phocoena) stranded or bycaught in the UK during 2012
Papachlimitzou, Alexandra; Barber, Jonathan L.; Losada, Sara; Bersuder, Philippe; Deaville, Rob; Brownlow, Andrew; Penrose, Rod; Jepson, Paul D.; Law, Robin J.
Marine Pollution Bulletin (2015)
A suite of twenty organophosphorus flame retardant compounds have been determined in blubber and liver tissue of twenty harbour porpoises stranded or bycaught in the UK during 2012 in order…
Porpoises: From predators to prey
Leopold, Mardik F.; Begeman, Lineke; Heße, Eileen; van der Hiele, Jaap; Hiemstra, Sjoukje; Keijl, Guido; Meesters, Erik H.; Mielke, Lara; Verheyen, Dorien; Gröne, Andrea
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)
Wisniewska, Danuta M; Ratcliffe, John M; Beedholm, Kristian; Christensen, Christian B; Johnson, Mark; Koblitz, Jens C; Wahlberg, Magnus; Madsen, Peter T
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…
High frequency components of ship noise in shallow water with a discussion of implications for harbor porpoises (Phocoena phocoena)
Hermannsen, Line; Beedholm, Kristian; Tougaard, Jakob; Madsen, Peter T.
The Journal of the Acoustical Society of America (2014)
Growing ship traffic worldwide has led to increased vessel noise with possible negative impacts on marine life. Most research has focused on low frequency components of ship noise, but for…
Postglacial climate changes and rise of three ecotypes of harbour porpoises, Phocoena phocoena, in western Palearctic waters
Fontaine, Michaël C.; Roland, Kathleen; Calves, Isabelle; Austerlitz, Frederic; Palstra, Friso P.; Tolley, Krystal A.; Ryan, Sean; Ferreira, Marisa; Jauniaux, Thierry; Llavona, Angela; Öztürk, Bayram; Öztürk, Ayaka A.; Ridoux, Vincent; Rogan, Emer; Sequeira, Marina; Siebert, Ursula; Vikingsson, Gísli A.; Borrell, Asunción; Michaux, Johan R.; Aguilar, Alex
Molecular Ecology (2014)
Despite no obvious barriers to gene flow in the marine realm, environmental variation and ecological specializations can lead to genetic differentiation in highly mobile predators. Here, we investigated the genetic…
Equal latency contours and auditory weighting functions for the harbour porpoise (Phocoena phocoena)
Wensveen, P. J.; Huijser, L. A. E.; Hoek, L.; Kastelein, R. A.
Journal of Experimental Biology (2014)
Loudness perception by human infants and animals can be studied under the assumption that sounds of equal loudness elicit equal reaction times (RTs). Simple RTs of a harbour porpoise to…
