Aquatic Mammals (2017)
Baseline data on the distribution patterns of animals disclose the dynamic function of habitat use as it relates to the accessibility of prey, social interactions, predator-prey interactions, and inter-habitat-patch mobility.…
The effects of marine traffic on the behaviour of Black Sea harbour porpoises (Phocoena phocoena relicta) within the Istanbul Strait, Turkey
Akkaya Bas, Aylin; Christiansen, Fredrik; Öztürk, Ayaka Amaha; Öztürk, Bayram; McIntosh, Caley
PLOS ONE (2017)
Marine traffic is threatening cetaceans on a local and global scale. The Istanbul Strait is one of the busiest waterways, with up to 2,500 vessels present daily. This is the…
COSEWIC assessment and status report on the harbour porpoise (Pacific Ocean population) Phocoena phocoena vomerina in Canada
Hall, A.; Heise, K.
COSEWIC Status Reports (2017)
Wildlife Species Description and Significance The Pacific Harbour Porpoise (Phocoena phocoena vomerina) is the smallest cetacean in British Columbia (BC), ranging from 1.5 to 1.6 m and 45 to 60…
Dive heart rate in harbour porpoises is influenced by exercise and expectations
McDonald, Birgitte I.; Johnson, Mark; Madsen, Peter T.
The Journal of Experimental Biology (2017)
The dive response, a decrease in heart rate (fH) and peripheral vasoconstriction, is the key mechanism allowing breath-hold divers to perform long-duration dives. This pronounced cardiovascular response to diving has…
Seasonal and diel patterns in cetacean use and foraging at a potential marine renewable energy site
Nuuttila, Hanna K.; Bertelli, Chiara M.; Mendzil, Anouska; Dearle, Nessa
Marine Pollution Bulletin (2018)
Marine renewable energy (MRE) developments often coincide with sites frequented by small cetaceans. To understand habitat use and assess potential impact from development, echolocation clicks were recorded with acoustic click…
Spatial avoidance to experimental increase of intermittent and continuous sound in two captive harbour porpoises
Kok, Annebelle C. M.; Engelberts, J. Pamela; Kastelein, Ronald A.; Helder-Hoek, Lean; Van de Voorde, Shirley; Visser, Fleur; Slabbekoorn, Hans
Environmental Pollution (2018)
The continuing rise in underwater sound levels in the oceans leads to disturbance of marine life. It is thought that one of the main impacts of sound exposure is the…
Feeding behaviour of harbour porpoises (Phocoena phocoena) in the Ems estuary
Weel, S. M. H.; Geelhoed, S. C. V.; Tulp, I.; Scheidat, M.
Lutra (2018)
Passive acoustic monitoring (PAM) was used to study the occurrence and distribution of feeding behaviour of harbour porpoises (Phocoena phocoena) in the Ems estuary, on the border between the Netherlands…
Environmental drivers of harbour porpoise fine-scale movements
van Beest, Floris M.; Teilmann, Jonas; Dietz, Rune; Galatius, Anders; Mikkelsen, Lonnie; Stalder, Dominique; Sveegaard, Signe; Nabe-Nielsen, Jacob
Marine Biology (2018)
Quantifying intraspecific variation in movement behaviour of marine predators and the underlying environmental drivers is important to inform conservation management of protected species. Here, we provide the first empirical data…
High rates of vessel noise disrupt foraging in wild harbour porpoises (Phocoena phocoena)
Wisniewska, Danuta Maria; Johnson, Mark; Teilmann, Jonas; Siebert, Ursula; Galatius, Anders; Dietz, Rune; Madsen, Peter Teglberg
Proceedings of the Royal Society B: Biological Sciences (2018)
Shipping is the dominant marine anthropogenic noise source in the world's oceans, yet we know little about vessel encounter rates, exposure levels and behavioural reactions for cetaceans in the wild,…
Oceanic movements, site fidelity and deep diving in harbour porpoises from Greenland show limited similarities to animals from the North Sea
Nielsen, N. H.; Teilmann, J.; Sveegaard, S.; Hansen, R. G.; Sinding, M. H. S.; Dietz, R.; Heide-Jørgensen, M. P.
Marine Ecology Progress Series (2018)
Harbour porpoises Phocoena phocoena are common in continental shelf areas of the North Atlantic, but little information is available on their occurrence outside coastal areas. In this study, 30 harbour…
