Understanding the role of seascape in shaping genetic and demographic population structure is highly challenging for marine pelagic species such as cetaceans for which there is generally little evidence of…
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…
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…
A visual and acoustic survey for harbour porpoises off North-West Africa: Further evidence of a discrete population
Boisseau, O.; Matthews, J.; Gillespie, D.; Lacey, C.; Moscrop, A.; El Ouamari, N.
African Journal of Marine Science (2007)
The distribution of harbour porpoises Phocoena phocoena in southern Europe and along the Atlantic African coast is poorly understood, with tentative assessments suggesting a discrete West African population with a…
Long-term feeding ecology and habitat use in harbour porpoises Phocoena phocoena from Scandinavian waters inferred from trace elements and stable isotopes
Fontaine, Michaël C; Tolley, Krystal A; Siebert, Ursula; Gobert, Sylvie; Lepoint, Gilles; Bouquegneau, Jean-Marie; Das, Krishna
BMC Ecol (2007)
We investigated the feeding ecology and habitat use of 32 harbour porpoises by-caught in 4 localities along the Scandinavian coast from the North Sea to the Barents Sea using time-integrative…
Echolocation signals of wild harbour porpoises, Phocoena phocoena
Villadsgaard, A.; Wahlberg, M.; Tougaard, J.
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…
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…
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,…
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…
