Sveegaard, Signe; Teilmann, Jonas; Tougaard, Jakob; Dietz, Rune; Mouritsen, Kim N.; Desportes, Geneviève; Siebert, Ursula
Marine Mammal Science (2010)
The population status of harbor porpoises has been of concern for several years, and the establishment of Marine Protected Areas (MPAs) has been suggested as a method to protect the…
Relationships between polychlorinated biphenyls and health status in harbor porpoises (Phocoena phocoena) stranded in the United Kingdom
Jepson, Paul D.; Bennett, Peter M.; Deaville, Robert; Allchin, Colin R.; Baker, John R.; Law, Robin J.
Environmental Toxicology and Chemistry (2005)
To investigate possible relationships between polychlorinated biphenyl (PCB) exposure and infectious disease mortality in harbor porpoises (Phocoena phocoena) in United Kingdom waters, summed blubber concentrations of 25 chlorobiphenyl congeners (Σ25CB)…
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…
