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…
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…
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…
Phylogeography of the finless porpoise (genus Neophocaena): testing the stepwise divergence hypothesis in the northwestern Pacific
Lin, Wenzhi; Frère, Céline H.; Karczmarski, Leszek; Xia, Jia; Gui, Duan; Wu, Yuping
Scientific Reports (2014)
We used 344 mitochondrial control region (717 bp) sequences from the finless porpoise (genus Neophocaena) from the northwestern Pacific to investigate the extent and manner in which past climatic oscillations may…

Mei, Zhigang; Zhang, Xinqiao; Huang, Shiang-Lin; Zhao, Xiujiang; Hao, Yujiang; Zhang, Lin; Qian, Zhengyi; Zheng, Jinsong; Wang, Kexiong; Wang, Ding
Biological Conservation (2014)
For the conservation of endangered animals to be effective, information on population distribution and abundance requires regular updating from census efforts. The Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) has recently…
Population structure and intergeneric hybridization in harbour porpoises Phocoena phocoena in British Columbia, Canada
Crossman, CA; Barrett-Lennard, LG; Taylor, EB
Endangered Species Research (2014)
We used variation at microsatellite loci and in mitochondrial DNA (mtDNA) to detect and quantify (1) hybridization between the harbour porpoises Phocoena phocoena and the Dall’s porpoises Phoconoides dalli and…
Fine-scale hydrodynamics influence the spatio-temporal distribution of harbour porpoises at a coastal hotspot
Jones, A. R.; Hosegood, P.; Wynn, R. B.; De Boer, M. N.; Butler-Cowdry, S.; Embling, C. B.
Progress in Oceanography (2014)
The coastal Runnelstone Reef, off southwest Cornwall (UK), is characterised by complex topography and strong tidal flows and is a known high-density site for harbour porpoise (Phocoena phocoena); a European…
Yangtze finless porpoises along the main channel of Poyang Lake, China: Implications for conservation
Dong, Lijun; Wang, Ding; Wang, Kexiong; li, Songhai; Mei, Zhigang; Wang, Shiyong; Akamatsu, Tomonari; Kimura, Satoko
Mar Mam Sci (2014)
Poyang Lake is the largest freshwater lake in China and flows into the Yangtze River. It is a traditional habitat for the endangered Yangtze finless porpoise, which has not been…
Measuring the economic value of increased precision in scientific estimates of marine mammal abundance and bycatch: Harbor porpoise Phocoena phocoena in the northeast U.S. gill-net fishery
Bisack, Kathryn D.; Magnusson, Gisele
North American Journal of Fisheries Management (2014)
Marine mammal stock assessments provide information that is valuable to public sector management and the private fishing sector; however, data are costly to collect. The precautionary approach, which is widely…
