Frontiers in Marine Science (2024)

Rapid changes of marine ecosystems resulting from human activities and climate change, and the subsequent reported rise of infectious diseases in marine mammals, highlight the urgency for timely detection of…


Harassment and killing of porpoises (“phocoenacide”) by fish‐eating Southern Resident killer whales (Orcinus orca)

Giles, Deborah A.; Teman, Sarah J.; Ellis, Samuel; Ford, John K. B.; Shields, Monika W.; Hanson, M. Bradley; Emmons, Candice K.; Cottrell, Paul E.; Baird, Robin W.; Osborne, Richard W.; Weiss, Michael; Ellifrit, David K.; Olson, Jennifer K.; Towers, Jared R.; Ellis, Graeme; Matkin, Dena; Smith, Courtney E.; Raverty, Stephen A.; Norman, Stephanie A.; Gaydos, Joseph K.

PLOS ONE (2018)

Killer whales have a cosmopolitan distribution and as a species are generalists, feeding on a variety of prey. However, local populations tend to specialise on specific prey types. In Icelandic…


Loop-mediated isothermal amplification (LAMP) as a confirmatory and rapid DNA detection method for grey seal (Halichoerus grypus) predation on harbour porpoises (Phocoena phocoena)

Heers, Teresa; van Neer, Abbo; Becker, André; Gross, Stephanie; Hansen, Kirstin Anderson; Siebert, Ursula; Abdulmawjood, Amir
Journal of Sea Research (2018)

An increasing number of harbour porpoises along the coastlines of northern Europe are victims of attacks by preying grey seals. To confirm grey seal attacks at a molecular level, a…


Causes of mortality of harbor porpoises Phocoena phocoena along the Atlantic and Pacific coasts of Canada

Fenton, H.; Daoust, P. Y.; Forzán, M. J.; Vanderstichel, R. V.; Ford, J. K. B.; Spaven, L.; Lair, S.; Raverty, S.
Diseases of Aquatic Organisms (2017)

There is increasing public interest in the overall health of the marine environment. Harbor porpoises Phocoena phocoena have a coastal distribution, and stranded animals function as sentinels for population and…


Predation by killer whales (Orcinus orca) and the evolution of whistle loss and narrow-band high frequency clicks in odontocetes

Morisaka, T.; Connor, R. C.
Journal of Evolutionary Biology (2007)

A disparate selection of toothed whales (Odontoceti) share striking features of their acoustic repertoires including the absence of whistles and high frequency but weak (low peak-to-peak source level) clicks that…
