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…
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…
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…
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…
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:…
Fine-scale hydrodynamics influence the spatio-temporal distribution of harbour porpoises at a coastal hotspot
Jones, A. R.; Hosegood, P.; Wynn, R. B.; De Boer, M. N.; Butler-Cowdry, S.; Embling, C. B.
Progress in Oceanography (2014)
The coastal Runnelstone Reef, off southwest Cornwall (UK), is characterised by complex topography and strong tidal flows and is a known high-density site for harbour porpoise (Phocoena phocoena); a European…
Effect of series of 1 to 2 kHz and 6 to 7 kHz up-sweeps and down-sweeps on the behavior of a harbor porpoise (Phocoena phocoena)
Kastelein, Ronald; Schop, Jessica; Gransier, Robin; Steen, Nele; Jennings, Nancy
Aquatic Mammals (2014)
To compare the effect of naval sonar up-sweeps and down-sweeps on the behavior of harbor porpoises, a harbor porpoise in a large pool was exposed to simulated low- and mid-frequency…
Beyond parasitism: Hepatic lesions in stranded harbor porpoises (Phocoena phocoena) without trematode (Campula oblonga) infections
Hiemstra, S.; Harkema, L.; Wiersma, L. C. M.; Keesler, R. I.
Veterinary Pathology (2014)
The liver can be an indicator of the health of an individual or of a group, which can be especially important to identify agents that can cause disease in multiple…
