Aquatic Mammals (2009)
Heterochrony, the change in timing of developmental processes, is thought to be a key process shaping the numerous limb morphologies of tetrapods. Through a delayed offset in digit development, all…
Epidemiological pattern of tattoo skin disease: A potential general health indicator for cetaceans
Van Bressem, M. F.; Van Waerebeek, K.; Aznar, F. J.; Raga, J. A.; Jepson, P. D.; Duignan, P.; Deaville, R.; Flach, L.; Viddi, F.; Baker, J. R.; Di Beneditto, A. P.; Echegaray, M.; Genov, T.; Reyes, J.; Felix, F.; Gaspar, R.; Ramos, R.; Peddemors, V.; Sanino, G. P.; Siebert, U.
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).…
Prey capture by harbor porpoises (Phocoena phocoena): A comparison between echolocators in the field and in captivity
Miller, L.A.
The Journal of the Marine Acoustics Society of Japan (2010)
The harbor porpoise, and other toothed whales, use a biosonar click sequence that resembles the sequence of cries used by insectivorous bats when hunting for and capturing prey. The temporal…
Abundance of harbor porpoise (Phocoena phocoena) in three Alaskan regions, corrected for observer errors due to perception bias and species misidentification, and corrected for animals submerged from view
Hobbs, Roderick C.; Waite, Janice M.
Fishery Bulletin (2010)
Estimating the abundance of cetaceans from aerial survey data requires careful attention to survey design and analysis. Once an aerial observer perceives a marine mammal or group of marine mammals,…
Genetic and historic evidence for climate-driven population fragmentation in a top cetacean predator: The harbour porpoises in European water
Fontaine, M. C.; Tolley, K. A.; Michaux, J. R.; Birkun, A.; Ferreira, M.; Jauniaux, T.; Llavona, A.; Ozturk, B.; Ozturk, A. A.; Ridoux, V.; Rogan, E.; Sequeira, M.; Bouquegneau, J.-M.; Baird, S. 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…
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…
