Bioacoustics (2010)
Sound plays an important role for toothed whales in foraging and communication. However, little is known about acoustic communication in the toothed whale species that only produce narrow band high…
Using T-PODs to assess variations in the occurrence of coastal bottlenose dolphins and harbour porpoises
Bailey, Helen; Clay, Gemma; Coates, Elizabeth A.; Lusseau, David; Senior, Bridget; Thompson, Paul M.
Aquatic Conservation: Marine and Freshwater Ecosystems (2010)
1. Assessments of anthropogenic impacts on cetaceans are often constrained by limited data on the extent to which these species use particular areas. 2. Timing porpoise detectors (T-PODs) are autonomous…
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…

Passive acoustic monitoring of bottlenose dolphin and harbour porpoise, in Cardigan Bay, Wales, with implications for habitat use and partitioning
Simon, Malene; Nuuttila, Hanna; Reyes-Zamudio, Mercedes M.; Ugarte, Fernando; Verfub, Ursula; Evans, Peter G.H.
Journal of the Marine Biological Association of the United Kingdom (2010)
Knowledge about harbour porpoise and bottlenose dolphin occurrence in Cardigan Bay Special Area of Conservation (SAC), Wales, is limited to daylight hours during summer, when conditions are suitable for traditional…
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…
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…
Gas bubble disease in harbor porpoises (Phocoena phocoena) stranded in British Columbia
Raverty, Stephen A.; Spavin, Lisa; Cottrell, Paul; Ford, John; Hall, Anna; Gaydos, Joe; Haulena, Martin; Ivančić, Marina
Conference of the International Association for Aquatic Animal Medicine (2010)
Harbour porpoises (Phocoena phocoena) are among the most abundant small cetaceans in the northeastern Pacific and there is a distinct bimodal seasonal stranding trend. Increased numbers of animals present in…
Single source sound production and dynamic beam formation in echolocating harbour porpoises (Phocoena phocoena)
Madsen, P. T.; Wisniewska, D.; Beedholm, K.
Journal of Experimental Biology (2010)
Echolocating toothed whales produce high-powered clicks by pneumatic actuation of phonic lips in their nasal complexes. All non-physeteroid toothed whales have two pairs of phonic lips allowing many of these…
Using habitat models to identify suitable sites for marine protected areas for harbour porpoises (Phocoena phocoena)
Embling, Clare B.; Gillibrand, Phil A.; Gordon, Jonathan; Shrimpton, Juliet; Stevick, Peter T.; Hammond, Philip S.
Biological Conservation (2010)
The harbour porpoise is a highly mobile species and thus represents a considerable challenge in the context of using marine protected areas (MPAs) for conservation. The shelf waters off the…
