Mitochondrial DNA (2015)
Yangtze finless porpoise, Neophocaena asiaeorientalis asiaeorientalis, is a cetacea animal which has been reclassified as a Critically Endangered species by IUCN in 2013. In this study, we determined the complete…
Bigg’s (transient) killer whale predation on Dall’s porpoise (Phocoenoides dalli) and harbour porpoise (Phocoena phocoena)
McInnes, Josh D.; Cullen, Kelsey D.; Browne, Lynette M.; Dehalt, Annette; Templeman, Nick M.
Technical Report for the Royal British Columbia Museum (2015)
(...) Two separate predation events were documented off the coast of Vancouver Island, British Columbia between the years 2013-2014. Both predation events occurred on small cetaceans from the Phocoenidae family:…
Behavioral responses of a Harbor porpoise (Phocoena phocoena) to 25-kHz FM sonar signals
Kastelein, Ronald A.; van den Belt, Ivanka; Helder-Hoek, Lean; Gransier, Robin; Johansson, Torbjörn
Aquatic Mammals (2015)
The effects of three sonar sound types (peak frequency ca. 25 kHz with high-frequency side bands at 71 and 121 kHz) on the behavior of a harbor porpoise (Phocoena phocoena)…
Pingers cause temporary habitat displacement in the harbour porpoise Phocoena phocoena
Kyhn, L. A.; Jørgensen, P. B.; Carstensen, J.; Bech, N. I.; Tougaard, J.; Dabelsteen, T.; Teilmann, J.
Marine Ecology Progress Series (2015)
Several studies have shown that pingers mitigate porpoise bycatch and thus pinger use is now mandatory in some fisheries—although the long-term effects of pinger exposure on porpoises have not been…
Harbour porpoises react to low levels of high frequency vessel noise
Dyndo, Monika; Wiśniewska, Danuta Maria; Rojano-Doñate, Laia; Teglberg Madsen, Peter
Scientific Reports (2015)
Cetaceans rely critically on sound for navigation, foraging and communication and are therefore potentially affected by increasing noise levels from human activities at sea. Shipping is the main contributor of…
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…
Eat and be eaten – Porpoise diet studies
Leopold, Maarten Frederik
Doctoral Thesis - Wageningen University (2015)
1. Diet studies of marine mammals typically summarise prey composition across all individuals studied. Variation in individual diets is usually ignored, but may be more than just “noise” around an…
Cetaceans of the Moroccan coast: Information from a reconstructed strandings database
Masski, Hicham; De Stéphanis, Renaud
Journal of the Marine Biological Association of the United Kingdom (2015)
Cetaceans of Morocco have been poorly studied to date, and only sporadic information comes from scientific cruises for this group. In an attempt to learn more on the occurrence, distribution…
Behavioral responses of a harbor porpoise (Phocoena phocoena) to 25.5- to 24.5-kHz sonar down-sweeps with and without side bands
Kastelein, Ronald A.; van den Belt, Ivanka; Gransier, Robin; Johansson, Torbjörn
Aquatic Mammals (2015)
Signals used in naval and long-range fish detection sonar often contain harmonics which may influence the behavior of harbor porpoises (Phocoena phocoena) more than the lower fundamental frequencies, so the…
Assessing the impact of underwater clearance of unexploded ordnance on Harbour porpoises (Phocoena phocoena) in the southern North Sea
von Benda-Beckmann, Alexander M.; Aarts, Geert; Sertlek, H. Özkan; Lucke, Klaus; Verboom, Wim C.; Kastelein, Ronald A.; Ketten, Darlene R.; van Bemmelen, Rob; Lam, Frans-Peter A.; Kirkwood, Roger J.; Ainslie, Michael A.
Aquatic Mammals (2015)
Large amounts of legacy unexploded ordnance (UXO) are still present in the North Sea. UXO are frequently accidentally encountered by fishermen and dredging vessels. Out of concern for human safety…
