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…
Updated marine mammal distribution and abundance estimates in British Columbia
Best, B. D.; Fox, C. H.; Williams, R.; Halpin, P. N.; Paquet, P. C.
Journal of Cetacean Research and Management (2015)
Information relating to the distribution and abundance of species is critical for effective conservation and management. For many species, including cetacean species of conservation concern, abundance estimates are lacking, out…
Cetacean noise criteria revisited in the light of proposed exposure limits for harbour porpoises
Tougaard, Jakob; Wright, Andrew J.; Madsen, Peter T.
Marine Pollution Bulletin (2015)
The impact of underwater noise on marine life calls for identification of exposure criteria to inform mitigation. Here we review recent experimental evidence with focus on the high-frequency cetaceans and…
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…
Identification of novel cetacean poxviruses in cetaceans stranded in south west England
Barnett, James; Dastjerdi, Akbar; Davison, Nick; Deaville, Rob; Everest, David; Peake, Julie; Finnegan, Christopher; Jepson, Paul; Steinbach, Falko
PLoS ONE (2015)
Poxvirus infections in marine mammals have been mainly reported through their clinical lesions and electron microscopy (EM). Poxvirus particles in association with such lesions have been demonstrated by EM and…
Identification of a novel gammaherpesvirus associated with (muco)cutaneous lesions in harbour porpoises (Phocoena phocoena)
van Beurden, Steven J.; IJsseldijk, Lonneke L.; Ordonez, Soledad R.; Förster, Christine; de Vrieze, Geert; Gröne, Andrea; Verheije, M. Hélène; Kik, Marja
Arch Virol (2015)
Herpesviruses infect a wide range of vertebrates, including toothed whales of the order Cetacea. One of the smallest toothed whales is the harbour porpoise (Phocoena phocoena), which is widespread in…
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…
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…
Cetacean distribution in the southern Black Sea: An acoustic approach
Saydam, Gülce
Master's Thesis - Middle East Technical University (2015)
Large numbers of small cetaceans (common dolphin, harbor porpoises and bottlenose dolphins) were hunted in the Black Sea until the hunting of cetaceans was banned in Turkey in 1983. Even…
Characteristics and propagation of airgun pulses in shallow water with implications for effects on small marine mammals
Hermannsen, Line; Tougaard, Jakob; Beedholm, Kristian; Nabe-Nielsen, Jacob; Madsen, Peter Teglberg
PLOS ONE (2015)
Airguns used in seismic surveys are among the most prevalent and powerful anthropogenic noise sources in marine habitats. They are designed to produce most energy below 100 Hz, but the…
