Aquatic Mammals (2012)
In 2007, the apparent increase in the number of harbor porpoises (Phocoena phocoena) stranding along the central California coast compared to the number of strandings the previous year resulted in…
The grey seal (Halichoerus grypus) as a predator of harbour porpoises (Phocoena phocoena)?
Haelters, Jan; Kerckhof, Francis; Jauniaux, Thierry; Degraer, Steven;
Aquatic Mammals (2012)
In September 2011, two harbour porpoises (Phocoena phocoena) presenting extensive traumatic lesions washed ashore in Belgium. Similar lesions, with large parts of skin and blubber missing, had not been recorded…
Harbour porpoises (Phocoena phocoena) and wind farms: a case study in the Dutch North Sea
Scheidat, Meike; Tougaard, Jakob; Brasseur, Sophie; Carstensen, Jacob; van Polanen Petel, Tamara; Teilmann, Jonas; Reijnders, Peter
Environmental Research Letters (2011)
The rapid increase in development of offshore wind energy in European waters has raised concern for the possible environmental impacts of wind farms. We studied whether harbour porpoise occurrence has…
Conservation plan for the harbour porpoise Phocoena phocoena in The Netherlands: Towards a favourable conservation status
Camphuysen, Kees C. J.; Siemensma, Marije L.
NIOZ Reports (2011)
- This is a conservation plan for the Harbour Porpoise Phocoena phocoena based on the current seasonal occurrence and abundance of porpoises within waters under Dutch jurisdiction. - The conservation…
Spatial and temporal distribution of harbour porpoises in relation to their prey
Sveegaard, S.
Doctoral Thesis - Aarhus Universitet (2011)
The population status of harbour porpoises has been of concern for several years due to anthropogenic influences, especially incidental bycatch in gillnet fisheries. Proper management of a wide-ranging species such…
Maternal care, calf training and site fidelity in a wild harbour porpoise in the North Sea
Camphuysen, Kees C. J.; Krop, Anton
Lutra (2011)
(...) Direct, undisturbed observations of interactions of mother and offspring in harbour porpoises (Phocoena phocoena) in the wild are extremely rare. Because harbour porpoises are seldom held and hardly breed…
Foraging behaviour and reproductive season habitat selection of northeast Pacific porpoises
Hall, A.
Doctoral Thesis - University of British Columbia (2011)
Behavioural observations are fundamental to understanding and defining the habitat needs of animals. I compiled the behavioural repertoires reported for harbour (Phocoena phocoena) and Dall’s porpoise (Phocoenoides dalli) by classifying…
The use of an air bubble curtain to reduce the received sound levels for harbor porpoises (Phocoena phocoena)
Lucke, Klaus; Lepper, Paul A.; Blanchet, Marie-Anne; Siebert, Ursula
The Journal of the Acoustical Society of America (2011)
In December 2005 construction work was started to replace a harbor wall in Kerteminde harbor, Denmark. A total of 175 wooden piles were piled into the ground at the waters…
Geographic variation of skeletal ontogeny and skull shape in the harbour porpoise (Phocoena phocoena)
Galatius, A.; Gol’din, P. E.
Canadian Journal of Zoology (2011)
All extant porpoise species show paedomorphic skeletal traits. These traits are hypothesized to be connected with rapid growth to reproductive size and could thus show geographic variation according to ecological…
Morphology of the odontocete melon and its implications for acoustic function
McKenna, Megan F.; Cranford, Ted W.; Berta, Annalisa; Pyenson, Nicholas D.
Marine Mammal Science (2011)
Toothed whales (crown Odontoceti) are unique among mammals in their ability to echolocate underwater, using specialized tissue structures. The melon, a structure composed of fat and connective tissue, is an…
