Habitat preferences and interannual variability in occurrence of the harbour porpoise Phocoena phocoena off northwest Scotland

Marubini, F.; Gimona, A.; Evans, P. G. H.; Wright, P. J.; Pierce, G. J.
Marine Ecology Progress Series (2009)

The harbour porpoise Phocoena phocoena is the most common cetacean around the British Isles, but knowledge of its ecology, habitat preferences and inter-annual variability is still inadequate. Here, sightings collected…


The possible reasons for bottlenose dolphins (Tursiops truncatus) participating in non-predatory aggressive interactions with harbour porpoises (Phocoena phocoena) in Cardigan Bay, Wales

Neale, Leonora
Honour's Thesis - University of Nottingham (2013)

Between 1991 and 2011, 137 harbour porpoises (Phocoena phocoena) died as a result of attacks by bottlenose dolphins (Tursiops truncatus) in Cardigan Bay. The suggested reasons for these non-predatory aggressive…


Mass-dependent predation risk and lethal dolphin-porpoise interactions

MacLeod, R.; MacLeod, C. D.; Learmonth, J. A.; Jepson, P. D.; Reid, R. J.; Deaville, R.; Pierce, G. J.
Proceedings of the Royal Society B: Biological Sciences (2007)

In small birds, mass-dependent predation risk (MDPR) is known to make the trade-off between avoiding starvation and avoiding predation dependent on individual mass. This occurs because carrying increased fat reserves…


Diet overlap between harbour porpoise and bottlenose dolphin: An argument in favour of interference competition for food?

Spitz, Jérôme; Rousseau, Yann; Ridoux, Vincent
Estuarine, Coastal and Shelf Science (2006)

In aquatic ecosystems, competitive interactions are occasionally described. Violent attacks on harbour porpoises by bottlenose dolphins were reported and it was proposed that this behavior could result from competitive interactions…


Identifying foraging behaviour of wild bottlenose dolphins (Tursiops truncatus) and harbour porpoises (Phocoena phocoena) with static acoustic dataloggers

Nuuttila, H. K.; Meier, R.; Evans, P. G. H.; Turner, J. R.; Bennell, J. D.; Hiddink, J. G.
Aquatic Mammals (2013)

Sound is the main means of communication for cetaceans, and studying their vocal behaviour can reveal important information about their activity patterns. As static acoustic monitoring (SAM) of whales, dolphins,…


Trace element concentrations, risks and their correlation with metallothionein genes polymorphism: A case study of narrow-ridged finless porpoises (Neophocaena asiaeorientalis) in the East China Sea

Liu, Jun; Chen, Bingyao; Jefferson, Thomas Allen; Wang, Hui; Yang, Guang
Science of the Total Environment (2016)

The concentration of trace elements (TEs) and their risk to narrow-ridged finless porpoises (Neophocaena asiaeorientalis) are still unclear. The present study determined the concentration of typical TEs in liver, kidney,…


Investigating potential associations between chronic exposure to polychlorinated biphenyls and infectious disease mortality in harbour porpoises from England and Wales

Jepson, Paul D.; Bennett, Peter M.; Allchin, Colin R.; Law, Robin J.; Kuiken, Thijs; Baker, John R.; Rogan, Emer; Kirkwood, James K.
Science of the Total Environment (1999)

Bioaccumulation of immunosuppressive organochlorines like polychlorinated biphenyls (PCBs) may pose a threat to the health and viability of cetacean populations. To investigate possible associations between chronic exposure to PCBs and…


Levels of organochlorine compounds, including PCDDS and PCDFS, in the blubber of cetaceans from the west coast of North America

Jarman, W. M.; Norstrom, R. J.; Muir, D. C. G.; Rosenberg, B.; Simon, M.; Baird, R. W.
Marine Pollution Bulletin (1996)

Levels of organochlorine compounds (PCDD, PCDF, PCB and organochlorine pesticides) were determined in cetaceans collected from the west coast of North America between 1986 and 1989. The samples included gray…
