Journal of Experimental Biology (2007)
Field recordings of harbour porpoises (Phocoena phocoena) were made in the inner Danish waters with a vertical array of three or four hydrophones. The back-calculated source level ranged from 178…
Climate change causing starvation in harbour porpoises?
Thompson, Paul; Ingram, Simon; Lonergan, Mike; Northridge, Simon; Hall, Ailsa; Wilson, Ben
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…
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,…
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…
Automatic Gain Control in Harbor Porpoises (Phocoena phocoena)? Central Versus Peripheral Mechanisms
Beedholm, Kristian; Miller, Lee A.
Aquatic Mammals (2007)
A previous study indicated no automatic gain control (AGC) in the auditory system of a harbor porpoise (Phocoena phocoena) as revealed by recording auditory evoked potentials to simulated echoes (Beedholm…
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…
Distribution and abundance of marine mammals in the coastal waters of British Columbia, Canada
Williams, R.; Thomas, L.
Journal of Cetacean Research and Management (2007)
Information on animal distribution and abundance is integral to wildlife conservation and management. However abundance estimates have not been available for many cetacean species inhabiting the coastal waters of Canada’s…
Biological and ecological factors related to trace element levels in harbour porpoises (Phocoena phocoena) from European waters
Lahaye, V.; Bustamante, P.; Law, R.J.; Learmonth, J.A.; Santos, M.B.; Boon, J.P.; Rogan, E.; Dabin, W.; Addink, M.J.; López, A.; Zuur, A.F.; Pierce, G.J.; Caurant, F.
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),…
Saving the Vaquita: Immediate action, not more data
JARAMILLO-LEGORRETA, ARMANDO; ROJAS-BRACHO, LORENZO; BROWNELL, ROBERT L.; READ, ANDREW J.; REEVES, RANDALL R.; RALLS, KATHERINE; TAYLOR, BARBARA L.
Conservation Biology (2007)
The recent likely extinction of the baiji (Chinese river dolphin [Lipotes vexillifer]) (Turvey et al. 2007) makes the vaquita (Gulf of California porpoise [Phocoena sinus]) the most endangered cetacean. The…
Stomach contents of bycaught harbour porpoises (Phocoena phocoena) from the Marmara sea
Tonay, A. M.; Dede, A.; Öztürk, A. A.
Rapports et Procès-Verbaux des Réunions de la Commission Internationale pour l'Exploration Scientifique de la Mer Méditerranée (2007)
The study was based on stomach content of four harbour porpoises bycaught in the coastal fishery in 2004 and 2006, on the Marmara Sea coast. Three fish species, horse mackerel…
