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…
Going with the flow: Tidal influence on the occurrence of the harbour porpoise (Phocoena phocoena) in the Marsdiep area, The Netherlands
IJsseldijk, Lonneke L.; Camphuysen, Kees C.J.; Nauw, Janine J.; Aarts, Geert
Journal of Sea Research (2015)
One of the most important factors explaining the distribution and behaviour of coastal marine mammals are tides. Tidal forces drive a large number of primary and secondary processes, such as…
Abundance and distribution of marine mammals in nearshore waters off New Jersey, USA
Whitt, A. D.; Powell, J. A.; Richardson, A. G.; Bosyk, J. R.
Journal of Cetacean Research and Management (2015)
Marine mammal abundance and distribution in New Jersey’s nearshore waters are not well known due to limited dedicated studies. The first year-round systematic surveys were conducted to determine the spatial/temporal…
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…
Harbour porpoises, Phocoena phocoena, in the Mediterranean Sea and adjacent regions
Fontaine, M. C.
Advances in Marine Biology (2016)
The harbour porpoise, Phocoena phocoena, is one of the best studied cetacean species owing to its common distribution along the coastal waters of the Northern Hemisphere. In European waters, strandings…
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.
Scientific Reports (2016)
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.…
