Ophelia (1994)
The reproduction and reproductive seasonality of 365 Danish harbour porpoises (Phocoena phocoena (L.)) incidentally caught in various gill nets or stranded, was studied. The animals were collected from all Danish…
Harbour porpoise (Phocoena phocoena) densities obtained from aerial surveys north of Fyn and in the Bay of Kiel
Heide-Jørgensen, M.-P.; Mosbech, A.; Teilmann, J.; Benke, H.; Schultz, W.
Ophelia (1992)
Aerial surveys covering 5117 linear kilometers were conducted at 91 and 183 m altitude under optimal sighting conditions in an area north of Fyn, Denmark, and in the Bay of…
Echolocation detections and digital video surveys provide reliable estimates of the relative density of harbour porpoises
Williamson, Laura D.; Brookes, Kate L.; Scott, Beth E.; Graham, Isla M.; Bradbury, Gareth; Hammond, Philip S.; Thompson, Paul M.
Methods in Ecology and Evolution (2016)
1. Robust estimates of the density or abundance of cetaceans are required to support a wide range of ecological studies and inform management decisions. Considerable effort has been put into…
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…
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,…
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…
DNA barcoding for the identification of soft remains of prey in the stomach contents of grey seals (Halichoerus grypus) and harbour porpoises (Phocoena phocoena)
Méheust, Eléonore; Alfonsi, Eric; Le Ménec, Patrick; Hassani, Sami; Jung, Jean-Luc
Marine Biology Research (2014)
In recent decades, grey seals (Halichoerus grypus) and harbour porpoises (Phocoena phocoena) have become more numerous along the coasts of Brittany in northwestern France. Their interactions with fisheries are of…
Equal latency contours and auditory weighting functions for the harbour porpoise (Phocoena phocoena)
Wensveen, P. J.; Huijser, L. A. E.; Hoek, L.; Kastelein, R. A.
Journal of Experimental Biology (2014)
Loudness perception by human infants and animals can be studied under the assumption that sounds of equal loudness elicit equal reaction times (RTs). Simple RTs of a harbour porpoise to…
Characterization of the temporomandibular joint of the harbour porpoise (Phocoena phocoena) and Risso’s dolphin (Grampus griseus)
McDonald, M.; Vapniarsky-Arzi, N.; Verstraete, F.J.M.; Staszyk, C.; Leale, D.M.; Woolard, K.D.; Arzi, B.
Archives of Oral Biology (2015)
Objectives The temporomandibular joint (TMJ) in cetaceans is largely uncharacterized. This study aims to describe the macroscopic, microscopic, biochemical and biomechanical features of the TMJ of two species of the…
COSEWIC assessment and update status report on the harbour porpoise Phocoena phocoena (Pacific Ocean population) in Canada
Baird, Robin W.
COSEWIC Status Reports (2003)
Species Information The harbour porpoise is one of the smallest cetacean species, born at 80-90 cm and only occasionally reaching lengths of close to 2 m. In general, harbour porpoises…
