PLOS ONE (2017)
Marine traffic is threatening cetaceans on a local and global scale. The Istanbul Strait is one of the busiest waterways, with up to 2,500 vessels present daily. This is the…
COSEWIC assessment and status report on the harbour porpoise (Pacific Ocean population) Phocoena phocoena vomerina in Canada
Hall, A.; Heise, K.
COSEWIC Status Reports (2017)
Wildlife Species Description and Significance The Pacific Harbour Porpoise (Phocoena phocoena vomerina) is the smallest cetacean in British Columbia (BC), ranging from 1.5 to 1.6 m and 45 to 60…
Meals on wheels? A decade of megafaunal visual and acoustic observations from offshore oil & gas rigs and platforms in the North and Irish Seas
Todd, Victoria Louise Georgia; Warley, Jane Clare; Todd, Ian Boyer
PLOS ONE (2016)
A decade of visual and acoustic detections of marine megafauna around offshore Oil & Gas (O&G) installations in the North and Irish Seas are presented. Marine megafauna activity was monitored…
Reversible bending of the dorsal fins of harbor porpoises (Phocoena phocoena) and a striped dolphin (Stenella coeruleoalba) in captivity
Kastelein, Ronald A.; Triesscheijn, Rob J. V.; Jennings, Nancy
Aquatic Mammals (2016)
The dorsal fin of odontocetes has, among other roles, hydrodynamic and thermoregulatory functions. In captivity, the dorsal fin sometimes bends laterally. Bending of the dorsal fin was described in 13…
Cognitive control of heart rate in diving harbor porpoises
Elmegaard, Siri L.; Johnson, Mark; Madsen, Peter T.; McDonald, Birgitte I.
Current Biology (2016)
Marine mammals have adapted to forage while holding their breath in a suite of aquatic habitats from shallow rivers to deep oceans. The key to tolerate such extensive apnea is…
Ultra-high foraging rates of harbor porpoises make them vulnerable to anthropogenic disturbance
Wisniewska, Danuta Maria; Johnson, Mark; Teilmann, Jonas; Rojano-Doñate, Laia; Shearer, Jeanne; Sveegaard, Signe; Miller, Lee A.; Siebert, Ursula; Madsen, Peter Teglberg
Current Biology (2016)
The question of how individuals acquire and allocate resources to maximize fitness is central in evolutionary ecology. Basic information on prey selection, search effort, and capture rates are critical for…
Harbour porpoise movement strategy affects cumulative number of animals acoustically exposed to underwater explosions
Aarts, G.; von Benda-Beckmann, A. M.; Lucke, K.; Sertlek, H. Ö.; van Bemmelen, R.; Geelhoed, S. C. V.; Brasseur, S.; Scheidat, M.; Lam, F. P. A.; Slabbekoorn, H.; Kirkwood, R.
Marine Ecology Progress Series (2016)
Anthropogenic sound in the marine environment can have negative consequences for marine fauna. Since most sound sources are intermittent or continuous, estimating how many individuals are exposed over time remains…
Parentage-based group composition and dispersal pattern studies of the Yangtze finless porpoise population in Poyang Lake
Chen, Minmin; Zheng, Yang; Hao, Yujiang; Mei, Zhigang; Wang, Kexiong; Zhao, Qingzhong; Zheng, Jinsong; Wang, Ding
International Journal of Molecular Sciences (2016)
Social behaviors are poorly known for the critically endangered Yangtze finless porpoise (YFP, Neophocaena asiaeorientalis asiaeorientalis). Here, group composition and dispersal patterns of the YFP population living in the Poyang…
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.…
Effect of construction-related activities and vessel traffic on marine mammals
Culloch, R. M.; Anderwald, P.; Brandecker, A.; Haberlin, D.; McGovern, B.; Pinfield, R.; Visser, F.; Jessopp, M.; Cronin, M.
Marine Ecology Progress Series (2016)
During the construction of a gas pipeline from an offshore gas field in northwest Ireland, a year-round shore-based marine mammal monitoring programme was undertaken. Using 6 yr of data, generalised…
