PLoS ONE (2013)
An unprecedented 85 harbour porpoises stranded freshly dead along approximately 100 km of Danish coastline from 7–15 April, 2005. This total is considerably above the mean weekly stranding rate for…
To ping or not to ping: The use of active acoustic devices in mitigating interactions between small cetaceans and gillnet fisheries
Dawson, S. M.; Northridge, S.; Waples, D.; Read, A. J.
Endangered Species Research (2013)
Active sound emitters (‘pingers’) are used in several gillnet fisheries to reduce bycatch of small cetaceans, and/or to reduce depredation by dolphins. Here, we review studies conducted to determine how…
Identifying foraging behaviour of wild bottlenose dolphins (Tursiops truncatus) and harbour porpoises (Phocoena phocoena) with static acoustic dataloggers
Nuuttila, H. K.; Meier, R.; Evans, P. G. H.; Turner, J. R.; Bennell, J. D.; Hiddink, J. G.
Aquatic Mammals (2013)
Sound is the main means of communication for cetaceans, and studying their vocal behaviour can reveal important information about their activity patterns. As static acoustic monitoring (SAM) of whales, dolphins,…
Using pingers to reduce bycatch of small cetaceans in Peru’s small-scale driftnet fishery
Mangel, Jeffrey C.; Alfaro-Shigueto, Joanna; Witt, Matthew J.; Hodgson, David J.; Godley, Brendan J.
Oryx (2013)
There is growing awareness that small-scale fisheries may have large impacts on threatened marine fauna. Bycatch of small cetaceans by the Peruvian small-scale driftnet fleet results in the deaths of…
Hearing pathways in the Yangtze finless porpoise, Neophocaena asiaeorientalis asiaeorientalis
Mooney, T. A.; Li, S.; Ketten, D. R.; Wang, K.; Wang, D.
Journal of Experimental Biology (2013)
How an animal receives sound may influence its use of sound. While ‘jaw hearing’ is well supported for odontocetes, work examining how sound is received across the head has been…
Brief behavioral response threshold levels of a harbor porpoise (Phocoena phocoena) to five helicopter dipping sonar signals (1.33 to 1.43 kHz)
Kastelein, Ronald; Gransier, Robin; van den Hoogen, Marjan; Hoek, Lean
Aquatic Mammals (2013)
Helicopter Long Range Active Sonar (HELRAS) is deployed from navy helicopters to detect submarines. Its worldwide use by NATO navies is expected to increase due to the increasing need to…
Habitat preferences and distribution of the harbour porpoise Phocoena phocoena west of Scotland
Booth, C. G.; Embling, C.; Gordon, J.; Calderan, S. V.; Hammond, P. S.
Marine Ecology Progress Series (2013)
The west coast of Scotland is comprised of complex coastlines and topography, and a range of physical processes influence its coastal marine environment. The region is host to one of…
Records of harbour porpoises (Phocoena phocoena) in fishing nets during the interwar period in Poland: Verification of archival materials
Psuty, Iwona
Aquatic Mammals (2013)
The Polish fisheries administration registered incidents of harbour porpoises caught by fishermen from fishing bases within the country's borders between 1922 and 1938. These data are unique in the Baltic…
Effects of pile-driving on harbour porpoises (Phocoena phocoena) at the first offshore wind farm in Germany
Dähne, Michael; Gilles, Anita; Lucke, Klaus; Peschko, Verena; Adler, Sven; Krügel, Kathrin; Sundermeyer, Janne; Siebert, Ursula
Environ. Res. Lett. (2013)
The first offshore wind farm 'alpha ventus' in the German North Sea was constructed north east of Borkum Reef Ground approximately 45 km north off the German coast in 2008…
Predictions from harbor porpoise habitat association models are confirmed by long-term passive acoustic monitoring
Brookes, Kate L.; Bailey, Helen; Thompson, Paul M.
The Journal of the Acoustical Society of America (2013)
Survey based habitat association models provide good spatial coverage, but only a snapshot in time of a species' occurrence in a particular area. A habitat association model for harbor porpoises…
