In the European North Sea, harbour porpoises are top predators with relatively long life spans and a limited capacity for metabolic biotransformation of contaminants compared to some other marine mammal…
Paedomorphosis in two small species of toothed whales (Odontoceti): How and why?
Galatius, Anders
Biological Journal of the Linnean Society (2010)
To evaluate and assess the ontogenetic background for paedomorphosis in phocoenids, samples of 144 harbour porpoises, 81 white-beaked dolphins, and 130 Commerson's dolphins were compared in terms of the development…
Propagation of narrow-band-high-frequency clicks: Measured and modeled transmission loss of porpoise-like clicks in porpoise habitats
DeRuiter, Stacy L.; Hansen, Michael; Koopman, Heather N.; Westgate, Andrew J.; Tyack, Peter L.; Madsen, Peter T.
The Journal of the Acoustical Society of America (2010)
Estimating the range at which harbor porpoises can detect prey items and environmental objects is integral to understanding their biosonar. Understanding the ranges at which they can use echolocation to…
Aspergillosis in the middle ear of a harbour porpoise (Phocoena phocoena): A case report
Prahl, Susanne; Jepson, Paul D.; Sanchez-Hanke, Marcos; Deaville, Rob; Siebert, Ursula
Mycoses (2010)
Hearing is one of the major senses in whales and dolphins (cetaceans). This is the first report of severe mycotic otitis media in a cetacean, a juvenile female harbour porpoise…

Berrow, S D; Deegan, B
Irish Whale and Dolphin Group (2010)
Muc Mhara – Ireland’s smallest whale. Proceedings of the 2nd Irish Whale and Dolphin Group International Whale Conference. Papers presented include, “Introduction: The harbour porpoise or Muc Mhara”, “An Irish…
The effect of signal duration on the underwater detection thresholds of a harbor porpoise (Phocoena phocoena) for single frequency-modulated tonal signals between 0.25 and 160 kHz
Kastelein, Ronald A.; Hoek, Lean; de Jong, Christ A. F.; Wensveen, Paul J.
The Journal of the Acoustical Society of America (2010)
The underwater hearing sensitivity of a young male harbor porpoise for tonal signals of various signal durations was quantified by using a behavioral psychophysical technique. The animal was trained to…
Odontocetes of the Southern Ocean Sanctuary
Van Waerebeek, K.; Leaper, R.; Baker, A. N.; Papastavrou, V.; Thiele, D.; Findlay, K.; Donovan, G.; Ensor, P.
Journal of Cetacean Research and Management (2010)
Twenty-eight odontocete species were identified as occupying sub-Antarctic and Antarctic habitat covered by the 1994 IWC-established Southern Ocean Sanctuary. Toothed whales evidently play an important part in the Antarctic polar…
Genetic and historic evidence for climate-driven population fragmentation in a top cetacean predator: The harbour porpoises in European water
Fontaine, Michaël C.; Tolley, Krystal A.; Michaux, Johan R.; Birkun, Alexei; Ferreira, Marisa; Jauniaux, Thierry; Llavona, Ángela; Öztürk, Bayram; Öztürk, Ayaka A; Ridoux, Vincent; Rogan, Emer; Sequeira, Marina; Bouquegneau, Jean-Marie; Baird, Stuart J. E.
Proceedings of the Royal Society B: Biological Sciences (2010)
Recent climate change has triggered profound reorganization in northeast Atlantic ecosystems, with substantial impact on the distribution of marine assemblages from plankton to fishes. However, assessing the repercussions on apex…
Interspecific variation of ontogeny and skull shape among porpoises (Phocoenidae)
Galatius, Anders; Berta, Annalisa; Frandsen, Marie Schou; Goodall, R. Natalie P.
Journal of Morphology (2010)
All extant members of Phocoenidae (porpoises) have been characterized as pedomorphic based on skeletal characters. To investigate the ontogenetic background for pedomorphosis and assess interspecific differences in ontogeny among phocoenids,…
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…
