PLoS ONE (2013)
Odontocetes produce a range of different echolocation clicks but four groups in different families have converged on producing the same stereotyped narrow band high frequency (NBHF) click. In microchiropteran bats,…
New material of Haborophocoena toyoshimai (Odontoceti: Phocoenidae) from the lower Pliocene Embetsu formation of Hokkaido, Japan
Ichishima, Hiroto; Kimura, Masaichi
Paleontological Research (2013)
A new specimen of the Early Pliocene porpoise Haborophocoena toyoshimai, comprising an incomplete cranium, was discovered from the Embetsu Formation near the locality of H. minutus, Haboro Town, Hokkaido, Japan.…
The possible reasons for bottlenose dolphins (Tursiops truncatus) participating in non-predatory aggressive interactions with harbour porpoises (Phocoena phocoena) in Cardigan Bay, Wales
Neale, Leonora
Honour's Thesis - University of Nottingham (2013)
Between 1991 and 2011, 137 harbour porpoises (Phocoena phocoena) died as a result of attacks by bottlenose dolphins (Tursiops truncatus) in Cardigan Bay. The suggested reasons for these non-predatory aggressive…
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…
Exposing the grey seal as a major predator of harbour porpoises
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…
High frequency components of ship noise in shallow water with a discussion of implications for harbor porpoises (Phocoena phocoena)
Hermannsen, Line; Beedholm, Kristian; Tougaard, Jakob; Madsen, Peter T.
The Journal of the Acoustical Society of America (2014)
Growing ship traffic worldwide has led to increased vessel noise with possible negative impacts on marine life. Most research has focused on low frequency components of ship noise, but for…
Harbor porpoise, Phocoena phocoena vomerina, in Cook Inlet, Alaska
Shelden, K.E.W.; Agler, B.A.; Brueggeman, J.J.; Cornick, L.A.; Speckman, S.G.; Prevel-Ramos, A.
Marine Fisheries Review (2014)
Harbor porpoise, Phocoena phocoena vomerina, in Cook Inlet, Alaska, are managed as part of the Gulf of Alaska (GOA) stock. It is not known if this population is distinct from…
