Biology Letters (2007)
(...) Recently, MacLeod et al. (2007) analysed data from harbour porpoises (Phocoena phocoena) stranded on Scottish North Sea coasts in March–May of 1993–2003. Comparing 2002–2003 data against baseline data from…
Decrease stress; train your animals: The effect of handling methods on cortisol levels in harbour porpoises (Phocoena phocoena) under human care
Desportes, Geneviève; Buholzer, Lisette; Anderson-Hansen, Kirstin; Blanchet, Marie-Anne; Acquarone, Mario; Shephard, Gwyneth; Brando, Sabrina; Vossen, Arndt; Siebert, Ursula
Aquatic Mammals (2007)
Circulating cortisol levels are accepted as a sensitive indicator of acute stress in marine mammals, particularly in relation with capture and handling. The present study provides the first long-term monitoring…
Modeling the detection range of fish by echolocating bottlenose dolphins and harbor porpoises
Au, Whitlow W. L.; Benoit-Bird, Kelly J.; Kastelein, Ronald A.
The Journal of the Acoustical Society of America (2007)
The target strength as a function of aspect angle were measured for four species of fish using dolphin-like and porpoise-like echolocation signals. The polar diagram of target strength values measured…
Starvation and sandeel consumption in harbour porpoises in the Scottish North Sea
MacLeod, Colin D.; Pierce, Graham J.; Begoña Santos, M.
Biology Letters (2007)
(...) Based on the evidence of a link between the likelihood of starvation and a lack of sandeels in the diet of porpoises in the Scottish North Sea in spring,…
Linking sandeel consumption and the likelihood of starvation in harbour porpoises in the Scottish North Sea: Could climate change mean more starving porpoises?
MacLeod, C. D.; Santos, M. B.; Reid, R. J.; Scott, B. E.; Pierce, G. J.
Biology Letters (2007)
Sandeels are known to be negatively affected by climate change in a number of ways. This study investigated whether these changes are affecting the harbour porpoise (Phocoena phocoena), a species…
Diet overlap between harbour porpoise and bottlenose dolphin: An argument in favour of interference competition for food?
Spitz, Jérôme; Rousseau, Yann; Ridoux, Vincent
Estuarine, Coastal and Shelf Science (2006)
In aquatic ecosystems, competitive interactions are occasionally described. Violent attacks on harbour porpoises by bottlenose dolphins were reported and it was proposed that this behavior could result from competitive interactions…
The status and distribution of cetaceans in the Black Sea and Mediterranean Sea
Reeves, R.; Notarbartolo di Sciara, G.
(2006)
(...) The Black Sea harbour porpoise, P. p. relicta, qualifies for listing as Endangered (EN) based on criteria A1d and A4c,d,e. The basis for inferences and suspicions leading to that…
Population structure and historical demography of eastern North Atlantic harbour porpoises inferred through mtDNA sequences
Tolley, K. A.; Rosel, P. E.
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…
Auditory brainstem response in a harbor porpoise show lack of automatic gain control for simulated echoes
Beedholm, Kristian; Miller, Lee A.; Blanchet, Marie-Anne
The Journal of the Acoustical Society of America (2006)
The auditory brainstem response (ABR) response to simulated echolocation clicks was studied in a harbor porpoise, Phocoena phocoena, to determine the relationship between the animal’s perceived echo strength and the…
The risk of infection from polychlorinated biphenyl exposure in the harbor porpoise (Phocoena phocoena): A case–control approach
Hall, Ailsa J.; Hugunin, Kelly; Deaville, Robert; Law, Robin J.; Allchin, Colin R.; Jepson, Paul D.
Environ Health Perspect (2006)
The objective of this study was to determine whether the risk of mortality from infectious disease in harbor porpoise in UK. waters increased with high exposure to polychlorinated biphenyls (PCBs),…
