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…

Van Bressem, Marie-Françoise; Van Waerebeek, Koen; Flach, Leonardo; Reyes, Julio César; de Oliveira Santos, Marcos César; Siciliano, Salvatore; Echegaray, Monica; Viddi, Francisco; Felix, Fernando; Crespo, Enrique; Sanino, Gian Paolo; Avila, Isabel Cristina; Fraijia, Natalia; Castro, Cristina
Scientific Committee Meeting Documents (2008)

Micro-organisms that are known or suspected to cause skin diseases in cetaceans are briefly reviewed. Viruses belonging to four families i.e. Caliciviridae, Herpesviridae, Papillomaviridae and Poxviridae were detected by electron…


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.

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…
