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…


Long-term feeding ecology and habitat use in harbour porpoises Phocoena phocoena from Scandinavian waters inferred from trace elements and stable isotopes

Fontaine, Michaël C; Tolley, Krystal A; Siebert, Ursula; Gobert, Sylvie; Lepoint, Gilles; Bouquegneau, Jean-Marie; Das, Krishna
BMC Ecol (2007)

We investigated the feeding ecology and habitat use of 32 harbour porpoises by-caught in 4 localities along the Scandinavian coast from the North Sea to the Barents Sea using time-integrative…


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…


Isotopic assessment of prey and habitat preferences of a cetacean community in the southwestern South Atlantic Ocean

Riccialdelli, L.; Newsome, S. D.; Fogel, M. L.; Goodall, R. N. P.
Marine Ecology Progress Series (2010)

We used stable carbon (δ13 C) and nitrogen (δ15 N) isotope analysis to investigate the trophic ecology of 8 small cetacean species of the southwestern South Atlantic Ocean: 6 delphinids…
