The Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) is an endangered freshwater porpoise subspecies unique to the Yangtze River basin. Seasonal variations in local distribution of the animal, as well as…
Estimating the success of protected areas for the vaquita, Phocoena sinus
Gerrodette, Tim; Rojas-Bracho, Lorenzo
Marine Mammal Science (2011)
Bycatch in artisanal gill nets threatens the vaquita, Phocoena sinus, with extinction. In 2008 the Mexican government announced a conservation action plan for this porpoise, with three options for a…

Sveegaard, Signe; Teilmann, Jonas; Tougaard, Jakob; Dietz, Rune; Mouritsen, Kim N.; Desportes, Geneviève; Siebert, Ursula
Marine Mammal Science (2010)
The population status of harbor porpoises has been of concern for several years, and the establishment of Marine Protected Areas (MPAs) has been suggested as a method to protect the…
Eat and be eaten – Porpoise diet studies
Leopold, Maarten Frederik
Doctoral Thesis - Wageningen University (2015)
1. Diet studies of marine mammals typically summarise prey composition across all individuals studied. Variation in individual diets is usually ignored, but may be more than just “noise” around an…

Tregenza, N.J.C.; Berrow, S. D.; Hammond, P. S.; Leaper, R.
ICES Journal of Marine Science (1997)
A programme to assess the cetacean by-catch in the Irish and UK set gillnet fisheries in the Celtic Sea was conducted from August 1992 to March 1994 using volunteer observers.…
Is a German harbour porpoise much more sensitive than a British one? Comparative analyses of mandatory measures for the protection of harbour porposes (Phocoena phocoena) during offshore wind farm ramming in Germany, Denmark and the UK
Luedeke, Jens
Proceedings of Meetings on Acoustics (2012)
Offshore wind farms (OWF) will soon contribute to significant growth in the renewable energy sector. At present just a few OWF have been built. As of 2012, Germany has an…
Report of Vaquita Expedition 2008 and current conservation actions
Jaramillo-Legorreta, Armando M.; Taylor, Barb; Gerrodette, Tim; Rankin, Shannon; Swift, Rene; Rojas-Bracho, Lorenzo
Scientific Committee Meeting Documents (2009)
Two scientific efforts brought the need for immediate actions to conserve vaquita as a high priority for the Mexican government. Passive acoustic techniques (Jaramillo-Legorreta, 2008) revealed a negative trend of…

The phylogeographic pattern of mitochondrial DNA variation in the Dall’s porpoise Phocoenoides dalli
MCMILLAN, W. O.; BERMINGHAM, E.
Molecular Ecology (1996)
We used 11 restriction endonucleases to study mtDNA variation in 101 Dall's porpoises Phocoenoides dalli from the Bering Sea and western North Pacific. There was little phylogeographic patterning among the…
