Marine Mammal Science (2017)
The effects of tagging on small cetaceans are difficult to assess due to logistical difficulties in recapturing the whales. In this study two narwhals, Monodon monoceros, and five harbor porpoises,…
Diet composition and food consumption rate of harbor porpoises (Phocoena phocoena) in the western Baltic Sea
Andreasen, Heidi; Ross, Stine D.; Siebert, Ursula; Andersen, Niels G.; Ronnenberg, Katrin; Gilles, Anita
Marine Mammal Science (2017)
Stomach content composition and prey-specific consumption rates of juvenile and adult harbor porpoises (Phocoena phocoena) were estimated from a data set including 339 stomachs collected over a 32 yr period…
Marine debris in harbour porpoises and seals from German waters
Unger, B.; Herr, H.; Benke, H.; Böhmert, M.; Burkhardt-Holm, P.; Dähne, M.; Hillmann, M.; Wolff-Schmidt, K.; Wohlsein, P.; Siebert, U.
Marine Environmental Research (2017)
Records of marine debris in and attached to stranded harbour porpoises (Phocoena phocoena), harbour seals (Phoca vitulina) and grey seals (Halichoerus grypus) were studied comprising information on 6587 carcasses collected…
Causes of mortality of harbor porpoises Phocoena phocoena along the Atlantic and Pacific coasts of Canada
Fenton, H.; Daoust, P. Y.; Forzán, M. J.; Vanderstichel, R. V.; Ford, J. K. B.; Spaven, L.; Lair, S.; Raverty, S.
Diseases of Aquatic Organisms (2017)
There is increasing public interest in the overall health of the marine environment. Harbor porpoises Phocoena phocoena have a coastal distribution, and stranded animals function as sentinels for population and…
Comparative physiology of vocal musculature in two odontocetes, the bottlenose dolphin (Tursiops truncatus) and the harbor porpoise (Phocoena phocoena)
Thometz, Nicole M.; Dearolf, Jennifer L.; Dunkin, Robin C.; Noren, Dawn P.; Holt, Marla M.; Sims, Olivia C.; Cathey, Brandon C.; Williams, Terrie M.
Journal of Comparative Physiology B (2017)
The mechanism by which odontocetes produce sound is unique among mammals. To gain insight into the physiological properties that support sound production in toothed whales, we examined myoglobin content ([Mb]),…
Phylogeography of the finless porpoise and potential implications for the taxonomy of Neophocaena spp.
Lin, Wenzhi; Karczmarski, Leszek; Wu, Yuping
Mammalian Biology (2017)
The finless porpoise (genus Neophocaena) is a poorly known cetacean of great conservation concern. Within its range, from western Pacific to northwestern Indian Ocean, there are currently two species recognized…
Grey seal attacks on harbour porpoises in the Eastern Scheldt: Cases of survival and mortality
Podt, A. E.; IJsseldijk, L. L.
Lutra (2017)
In the southern North Sea, hundreds of mutilated harbour porpoise carcasses (Phocoena phocoena) are found each year on beaches. Recent studies have confirmed that these concern the remains of predation…
Resilience of harbor porpoises to anthropogenic disturbance: Must they really feed continuously?
Hoekendijk, Jeroen P. A.; Spitz, Jerome; Read, Andrew J.; Leopold, Mardik F.; Fontaine, Michael C.
Marine Mammal Science (2017)
...Recently, Wisniewska et al. (2016) used high-resolution digital acoustic tags (DTAGs) to monitor the foraging behavior of five harbor porpoises in Danish waters. This approach provided detailed observations on the…
Don’t forget the porpoise: Acoustic monitoring reveals fine scale temporal variation between bottlenose dolphin and harbour porpoise in Cardigan Bay SAC
Nuuttila, Hanna K.; Courtene-Jones, Winnie; Baulch, Sarah; Simon, Malene; Evans, Peter G. H.
Marine Biology (2017)
Populations of bottlenose dolphin and harbour porpoise inhabit Cardigan Bay, which was designated a Special Area of Conservation (SAC), with bottlenose dolphin listed as a primary feature for its conservation…
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…
