Current Biology (2016)
Marine mammals have adapted to forage while holding their breath in a suite of aquatic habitats from shallow rivers to deep oceans. The key to tolerate such extensive apnea is…
Emission of social sounds by marine animals
Au, W. W. L.; Hastings, M. C.
Principles of Marine Bioacoustics (2008)
(...) Sound emissions by odontocetes (toothed whales and dolphins) can be classified into two broad categories of frequency-varying continuous tonal sounds referred to as whistles and broadband clicks (Evans, 1967),…
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
Ohizumi, Hiroshi; Kuramochi, Toshiaki; Kubodera, Tsunemi; Yoshioka, Motoi; Miyazaki, Nobuyuki
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.…
Observations of captive and wild cetaceans
Brown, David H.; Norris, Kenneth S.
Journal of Mammalogy (1956)
(...) During the first months of operation (March, 1954 to Sept. 1955) of the new oceanarium, Marineland of the Pacific, we have had numerous opportunities to observe the dolphins and…
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…
Functional analysis of the surfacing behaviour in the harbour porpoise, Phocoena phocoena (L.)
Amundin, M.
Zeitschrift für Säugetierkunde (1974)
This study confirms earlier observations of apparently involuntary movements, strongly associated with the breathing. The movements include taxes - a dorsal flexure of the thorax and steering movements with the…
Observations of odontocetes in central Californian waters
Brownell, R. L. Jr.
Norsk Hvalfangst-Tidende (1964)
(...) This reports observations of odontocetes made during the summer of 1963 in central Californian waters. I made my observations aboard catcher boats of the Golden Gate Fishing Company, Point…
