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,…


Feeding habits of Dall’s porpoises (Phocoenoides dalli) in the subarctic North Pacific and the Bering Sea basin and the impact of predation on mesopelagic micronekton

Deep Sea Research Part I: Oceanographic Research Papers (2003)

We investigated the stomach contents of Dall's porpoises collected in pelagic waters spanning most of their range in the North Pacific and the Bering Sea. Analysis revealed the porpoises fed…


Listening to echolocation clicks with PODs

Tregenza, Nick; Dawson, Steve; Rayment, Will; Verfuss, Ursula
Modern Acoustics and Signal Processing (2016)

Monitoring echolocation using SAMs—static acoustic monitors—such as T-PODs or, more recently, C-PODs—has provided a wealth of information on the fine-scale distribution and activity of dolphins, porpoises and other toothed whales.…


Harbour porpoise movement strategy affects cumulative number of animals acoustically exposed to underwater explosions

Aarts, G.; von Benda-Beckmann, A. M.; Lucke, K.; Sertlek, H. Ö.; van Bemmelen, R.; Geelhoed, S. C. V.; Brasseur, S.; Scheidat, M.; Lam, F. P. A.; Slabbekoorn, H.; Kirkwood, R.
Marine Ecology Progress Series (2016)

Anthropogenic sound in the marine environment can have negative consequences for marine fauna. Since most sound sources are intermittent or continuous, estimating how many individuals are exposed over time remains…
