The vaquita (Phocoena sinus) is the world's most endangered marine mammal with ≈245 individuals remaining in 2008. This species of porpoise is endemic to the northern Gulf of California, Mexico,…


Effects of offshore pile driving on harbour porpoise abundance in the German Bight

Brandt, Miriam J.; Dragon, Anne-Cécile; Diederichs, Ansgar; Schubert, Alexander; Kosarev, Vladislav; Nehls, Georg; Wahl, Veronika; Michalik, Andreas; Braasch, Alexander; Hinz, Claus; Ketzer, Christian; Todeskino, Dieter; Gauger, Marco; Laczny, Martin; Pipe, Werner
Report for Offshore Forum Windenergie (2016)

This study analyses the effects of the construction of eight offshore wind farms within the German North Sea between 2009 and 2013 on harbour porpoises (Phocoena phocoena). It combines porpoise…


Listening to echolocation clicks with PODs

Tregenza, Nick; Dawson, Steve; Rayment, Will; Verfuss, Ursula
Modern Acoustics and Signal Processing (2016)

Monitoring echolocation using SAMs—static acoustic monitors—such as T-PODs or, more recently, C-PODs—has provided a wealth of information on the fine-scale distribution and activity of dolphins, porpoises and other toothed whales.…


Assessing harbour porpoise populations in south-west Wales, data issues and implications for conservation and management

Oakley, J. A.; Jenkins, R. E.; Thomas, T.; Williams, A. T.; Phillips, M. R.
Ocean & Coastal Management (2016)

The UK Government was recently criticised for failing to fulfil its obligations under the Habitats Directive in respect of designating protected areas for Harbour Porpoise Phocoena phocoena. At the centre…


Organization of the sleep-related neural systems in the brain of the harbour porpoise (Phocoena phocoena)

Dell, Leigh-Anne; Patzke, Nina; Spocter, Muhammad A.; Siegel, Jerome M.; Manger, Paul R.
Journal of Comparative Neurology (2016)

The present study provides the first systematic immunohistochemical neuroanatomical investigation of the systems involved in the control and regulation of sleep in an odontocete cetacean, the harbor porpoise (Phocoena phocoena).…


Endangered species, ecosystem integrity, and human livelihoods

Aburto-Oropeza, Octavio; López-Sagástegui, Catalina; Moreno-Báez, Marcia; Mascareñas-Osorio, Ismael; Jiménez-Esquivel, Victoria; Johnson, Andrew Frederick; Erisman, Brad
Conservation Letters (2016)

If efforts to conserve endangered species lack long-term visions and neglect the human dimensions, conservation success will be questionable. Exclusion of stakeholders in decisions can lead to mistrust and polarization…


Habitat-based cetacean density models for the U.S. Atlantic and Gulf of Mexico

Roberts, Jason J.; Best, Benjamin D.; Mannocci, Laura; Fujioka, Ei; Halpin, Patrick N.; Palka, Debra L.; Garrison, Lance P.; Mullin, Keith D.; Cole, Timothy V. N.; Khan, Christin B.; McLellan, William A.; Pabst, D. Ann; Lockhart, Gwen G.
Scientific Reports (2016)

Cetaceans are protected worldwide but vulnerable to incidental harm from an expanding array of human activities at sea. Managing potential hazards to these highly-mobile populations increasingly requires a detailed understanding…
