Marine Ecology Progress Series (2014)
During recent decades, the 2 distinct harbour porpoise populations of the Baltic Sea have decreased sharply in abundance. The Baltic Proper population is down to a few hundred individuals and…
Effects of noise and by-catch on a Danish harbour porpoise population
Nabe-Nielsen, Jacob; Sibly, Richard M.; Tougaard, Jakob; Teilmann, Jonas; Sveegaard, Signe
Ecological Modelling (2014)
Ships and wind turbines generate noise, which can have a negative impact on marine mammal populations by scaring animals away. Effective modelling of how this affects the populations has to…
Do man-made structures and water depth affect the diel rhythms in click recordings of harbor porpoises (Phocoena phocoena)?
Brandt, Miriam J.; Hansen, Sophie; Diederichs, Ansgar; Nehls, Georg
Mar Mam Sci (2014)
The construction of industrial offshore structures may lead to colonization by a variety of marine organisms resulting in locally enhanced biodiversity and biomass, which may then affect the habitat use…
Genetic diversity and population structure of the critically endangered Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) as revealed by mitochondrial and microsatellite DNA
Chen, Minmin; Zheng, Jinsong; Wu, Min; Ruan, Rui; Zhao, Qingzhong; Wang, Ding
International Journal of Molecular Sciences (2014)
Ecological surveys have indicated that the population of the critically endangered Yangtze finless porpoise (YFP, Neophocaena asiaeorientalis asiaeorientalis) is becoming increasingly small and fragmented, and will be at high risk…
Unique feeding morphology in a new prognathous extinct porpoise from the Pliocene of California
Racicot, Rachel A.; Deméré, Thomas A.; Beatty, Brian L.; Boessenecker, Robert W.
Current Biology (2014)
Modern porpoises (Odontoceti: Phocoenidae) are some of the smallest cetaceans and usually feed near the seafloor on small fish and cephalopods. Within both extinct and extant phocoenids, no evidence for…

Leopold, M. F.; Begeman, L.; van Bleijswijk, J. D. L.; IJsseldijk, L. L.; Witte, H. J.; Grone, A.
Proceedings of the Royal Society B: Biological Sciences (2014)
Harbour porpoises (Phocoena phocoena) stranding in large numbers around the southern North Sea with fatal, sharp-edged mutilations have spurred controversy among scientists, the fishing industry and conservationists, whose views about…
Assessing the impact of underwater clearance of unexploded ordnance on Harbour porpoises (Phocoena phocoena) in the southern North Sea
von Benda-Beckmann, Alexander M.; Aarts, Geert; Sertlek, H. Özkan; Lucke, Klaus; Verboom, Wim C.; Kastelein, Ronald A.; Ketten, Darlene R.; van Bemmelen, Rob; Lam, Frans-Peter A.; Kirkwood, Roger J.; Ainslie, Michael A.
Aquatic Mammals (2015)
Large amounts of legacy unexploded ordnance (UXO) are still present in the North Sea. UXO are frequently accidentally encountered by fishermen and dredging vessels. Out of concern for human safety…
