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…


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.…


A contribution to the study on the three cetacean species stranded along the Bulgarian Black Sea coast

Evtimova, V.; Delov, V.; Parvanov, D.; Grozdanov, A.; Velina, Y.
Annuaire de l’Université de Sofia “St. Kliment Ohridski” Faculte de Biologie (2016)

The study was conducted by examining stranded cetaceans while explicitly searching for dead marine mammals. Observations were made through covering transects along the Bulgarian Black Sea coast. The data collection…


Observations on Pacific cetaceans of Californian and Mexican waters

Norris, K. S.; Prescott, J. H.
University of California Publications in Zoology (1961)

(...) For five years we have systematically gathered information of every available kind related to these animals. Fifteen species have been observed in sufficient detail to be considered here. These…


Investigations on the osteology and the functional morphology of the flipper of whales and dolphins (Cetacea)

Benke, H.
Investigations on Cetacea (1993)

Of the 79 recent species of cetaceans 51 have been examined relative to the osteology of the flipper and the scapula and, in addition to this, video-recordings of 13 different…


A review of human impact on small cetaceans

Northridge, S.; Pilleri, G.
Investigations on Cetacea (1986)

(...) This document attempts to gather together as much information as is available on the extent of current killings of small cetaceans throughout the world, and also to highlight some…
