Marine Environmental Research (2007)
Selected trace elements (Cd, Cu, Hg, Se, Zn) were measured in the kidneys and the liver of 104 harbour porpoises (Phocoena phocoena) stranded along the coasts of France, Galicia (Spain),…
Mass-dependent predation risk and lethal dolphin-porpoise interactions
MacLeod, R.; MacLeod, C. D.; Learmonth, J. A.; Jepson, P. D.; Reid, R. J.; Deaville, R.; Pierce, G. J.
Proceedings of the Royal Society B: Biological Sciences (2007)
In small birds, mass-dependent predation risk (MDPR) is known to make the trade-off between avoiding starvation and avoiding predation dependent on individual mass. This occurs because carrying increased fat reserves…
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…
Time allocation and diving behaviour of harbour porpoises (Phocoena phocoena) in Danish and adjacent waters
TEILMANN, JONAS; LARSEN, FINN; DESPORTES, GENEVIÉVE
Journal of Cetacean Research and Management (2007)
To gain insight into the time allocation and diving behaviour of harbour porpoises in Danish and adjacent waters, satellite linked dive recorders were mounted on 14 harbour porpoises. The animals…
The impact of stress on cytokine and haptoglobin mRNA expression in blood samples from harbour porpoises (Phocoena phocoena)
Fonfara, S.; Siebert, U.; Prange, A.; Colijn, F.
Journal of the Marine Biological Association of the UK (2007)
Cytokines are important cell mediators involved in immune responses. Their expression can be modulated by numerous factors, including stress. The aim of this study was to compare cytokine mRNA expression…
Geographical distribution of polybrominated diphenyl ethers (PBDEs) and organochlorines in small cetaceans from Asian waters
Kajiwara, Natsuko; Kamikawa, Satoko; Ramu, Karri; Ueno, Daisuke; Yamada, Tadasu K.; Subramanian, Annamalai; Lam, Paul K. S.; Jefferson, Thomas A.; Prudente, Maricar; Chung, Kyu-Hyuck; Tanabe, Shinsuke
Chemosphere (2006)
Polybrominated diphenyl ethers (PBDEs) are one of the flame retardants widely used in plastics, textiles, electronic appliances, and electrical household appliances. In this study, PBDEs and organochlorine compounds (OCs) were…
The phylogenetic relationships and biogeography of true porpoises (Mammalia: Phocoenidae) based on morphological data
Fajardo-Mellor, Liliana; Berta, Annalisa; Brownell, Robert L.; Boy, Claudia C.; Goodall, R. Natalie P.
Marine Mammal Sci (2006)
Prior studies of phylogenetic relationships among phocoenids based on morphology and molecular sequence data conflict and yield unresolved relationships among species. This study evaluates a comprehensive set of cranial, postcranial,…
Reactions of captive harbor porpoises (Phocoena phocoena) to pinger-like sounds
Teilmann, Jonas; Tougaard, Jakob; Miller, Lee A.; Kirketerp, Tim; Hansen, Kirstin; Brando, Sabrina
Marine Mammal Sci (2006)
Pingers on gill nets can reduce bycatch of harbor porpoises. If harbor porpoises habituate to pingers, the effect may be reduced or lost. Two captive harbor porpoises were exposed to…
Population structure and historical demography of eastern North Atlantic harbour porpoises inferred through mtDNA sequences
Tolley, KA; Rosel, PE
Marine Ecology Progress Series (2006)
The harbour porpoise Phocoena phocoena experiences high rates of incidental mortality in commercial fisheries, and in some areas these rates are sufficiently high to justify concern over population sustainability. Given…
Harbour Porpoises on Horns Reef – Effects of the Horns Reef Wind Farm (Final Report)
Tougaard, Jakob; Carstensen, Jacob; Wisz, Mary S.; Jespersen, Martin; Teilmann, Jonas; Ilsted Bech, Nikolaj; Skov, Henrik
NERI Technical Report to Vattenfall A/S (2006)
The monitoring program on harbour porpoises at Horns Rev Offshore Wind Farm in the Danish North Sea, initiated in 1999, has now come to an end with collection of final…
