Habitat-based cetacean density models for the U.S. Atlantic and Gulf of Mexico

Roberts, Jason J.; Best, Benjamin D.; Mannocci, Laura; Fujioka, Ei; Halpin, Patrick N.; Palka, Debra L.; Garrison, Lance P.; Mullin, Keith D.; Cole, Timothy V. N.; Khan, Christin B.; McLellan, William A.; Pabst, D. Ann; Lockhart, Gwen G.

Cetaceans are protected worldwide but vulnerable to incidental harm from an expanding array of human activities at sea. Managing potential hazards to these highly-mobile populations increasingly requires a detailed understanding…


Exploitation of coastal fish communities by harbour porpoises Phocoena phocoena during nursing periods in German Baltic waters

Pinzone, M.; Michel, L. N.; Gallus, A.; Brundiers, K.; Sturaro, N.; Andreasen, H.; Dähne, M.; Lepoint, G.; Siebert, U.; Das, K.; Benke, H.
Zoology Conference 2017 (2016)

The increased number of juvenile and newborn harbour porpoise strandings along the German Baltic coasts in summer provides evidence for a possible local calving and nursing ground in this area.…


Seasonal habitat-based density models for a marine top predator, the harbor porpoise, in a dynamic environment

Gilles, A.; Viquerat, S.; Becker, E. A.; Forney, K. A.; Geelhoed, S. C. V.; Haelters, J.; Nabe-Nielsen, J.; Scheidat, M.; Siebert, U.; Sveegaard, S.; van Beest, F. M.; van Bemmelen, R.; Aarts, G.
Ecosphere (2016)

Effective species conservation and management requires information on species distribution patterns, which is challenging for highly mobile and cryptic species that may be subject to multiple anthropogenic stressors across international…


Habitat shapes skull profile of small cetaceans: Evidence from geographical variation in Black Sea harbour porpoises (Phocoena phocoena relicta)

Gol’din, Pavel; Vishnyakova, Karina
Zoomorphology (2016)

Morphological differentiation in skull shape in small toothed whales is sometimes explained as driven by differences in ontogeny or adaptation to a benthic or pelagic habitat. To test these hypotheses,…


Riding the tide: Use of a moving tidal-stream habitat by harbour porpoises

Benjamins, S.; Dale, A.; van Geel, N.; Wilson, B.
Marine Ecology Progress Series (2016)

Tidal-stream habitats present periodically fast-flowing, turbulent conditions. Evidence suggests that these conditions benefit top predators such as harbour porpoises Phocoena phocoena, presumably allowing them to optimise exploitation of prey resources.…


Distribution of Dall’s porpoise, Phocoenoides dalli, in the North Pacific and Bering Sea, based on T/S Oshoro Maru 2012 summer cruise data

Suzuki, Sachiko; Sekiguchi, Keiko; Mitani, Yoko; Onishi, Hiroji; Kamito, Takehiko
Zoological Science (2016)

Dall's porpoise (Phocoenoides dalli) is a small toothed cetacean, widely inhabiting the North Pacific Ocean and adjacent seas, between about 30 and 62°N; however, only limited studies of its ecology…


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…


Porpoises: From predators to prey

Leopold, Mardik F.; Begeman, Lineke; Heße, Eileen; van der Hiele, Jaap; Hiemstra, Sjoukje; Keijl, Guido; Meesters, Erik H.; Mielke, Lara; Verheyen, Dorien; Gröne, Andrea
Journal of Sea Research (2015)

Along the Dutch shores hundreds of harbour porpoises Phocoena phocoena are stranded each year. A recurrent phenomenon in the Netherlands is a surge of strandings in late winter and early…
