Diseases of Aquatic Organisms (2009)
The presence of tattoo skin disease (TSD) was examined in 1392 free-ranging and dead odontocetes comprising 17 species from the Americas, Europe, South Africa, New Zealand and Greenland. We investigated…
Temporary shift in masked hearing thresholds in a harbor porpoise (Phocoena phocoena) after exposure to seismic airgun stimuli
Lucke, Klaus; Siebert, Ursula; Lepper, Paul A.; Blanchet, Marie-Anne
The Journal of the Acoustical Society of America (2009)
An auditory study was conducted to derive data on temporary threshold shift (TTS) induced by single impulses. This information should serve as basis for the definition of noise exposure criteria…
Recovery Plan for Baltic Harbour Porpoises Jastarnia Plan (Revision)
(2009)
The harbour porpoise (Phocoena phocoena) is widely distributed in shelf waters of the temperate North Atlantic and North Pacific Oceans and in some semi-enclosed seas (e.g. the Black, Baltic Seas…
Dentinal anomalies in teeth of harbour porpoises (Phocoena phocoena) from Scottish waters: Are they linked to sexual maturation and environmental events?
Luque, P. L.; Pierce, G. J.; Learmonth, J. A.; Santos, M. B.; Ieno, E.; López, A.; Reid, R. J.; Rogan, E.; González, A. F.; Boon, J.; Law, R. J.; Lockyer, C. H.
Journal of the Marine Biological Association of the United Kingdom (2009)
We examined the tooth ultra-structure of harbour porpoises (Phocoena phocoena) from Scottish waters to determine whether the incidence of mineralization anomalies could be related to certain life history events (e.g.…
Harbour porpoise (Phocoena phocoena) conservation management: A dimensional approach
Jenkins, Rhian E.; Brown, Raymond D.H.; Phillips, Michael R.
Marine Policy (2009)
Harbour porpoises Phocoena phocoena are protected under the Habitats and Species Directive (92/43/EEC) and listed as a priority species in the City and County of Swansea's Biodiversity Action Plan (BAP).…
Spatial and temporal impact of pingers on porpoises
Carlström, Julia; Berggren, Per; Tregenza, Nick J. C.
Canadian Journal of Fisheries and Aquatic Sciences (2009)
Bycatches are considered the most serious threat to harbour porpoises (Phocoena phocoena) and other small cetaceans worldwide. Pingers are used to reduce bycatch levels, but may also deter porpoises from…
Spatio-temporal associations between harbour porpoise Phocoena phocoena and specific fisheries in the German Bight
Herr, Helena; Fock, Heino O.; Siebert, Ursula
Biological Conservation (2009)
Interactions between cetaceans and fisheries are a major concern of cetacean conservation and fisheries management, as by-catch and resource competition occur as a result. To assess potential interaction between porpoises…
Diel echolocation activity of harbour porpoises (Phocoena phocoena) around North Sea offshore gas installations
Todd, V. L. G.; Pearse, W. D.; Tregenza, N. C.; Lepper, P. A.; Todd, I. B.
ICES Journal of Marine Science (2009)
Echolocation clicks of harbour porpoises (Phocoena phocoena) were detected with T-PODs, autonomous, passive, acoustic-monitoring devices, deployed from an offshore-exploration-drilling-rig and gas-production-platform complex in the Dogger Bank region of the North…
Functional morphology of the nasal complex in the harbor porpoise (Phocoena phocoena L.)
Huggenberger, Stefan; Rauschmann, Michael A.; Vogl, Thomas J.; Oelschläger, Helmut H. A.
Anatomical Record (2009)
Toothed whales (Odontoceti, Cetacea) are the only aquatic mammals known to echolocate, and probably all of them are able to produce click sounds and to synthesize their echoes into a…
Acoustic behaviour of echolocating porpoises during prey capture
DeRuiter, S. L.; Bahr, A.; Blanchet, M.-A.; Hansen, S. F.; Kristensen, J. H.; Madsen, P. T.; Tyack, P. L.; Wahlberg, M.
Journal of Experimental Biology (2009)
Porpoise echolocation has been studied previously, mainly in target detection experiments using stationed animals and steel sphere targets, but little is known about the acoustic behaviour of free-swimming porpoises echolocating…
