(...) gray seal (Halichoerus grypus) consumption of harbor porpoises—whether predation or scavenging—might reflect a change in gray seal feeding habits in the southern North Sea (Haelters et al. 2012), where…
Brief behavioral response threshold level of a harbor porpoise (Phocoena phocoena) to an impulsive sound
Kastelein, Ronald; Steen, Nele; Gransier, Robin; de Jong, Christ A. F.
Aquatic Mammals (2013)
Underwater impulsive sounds may affect the behavior of harbor porpoises within a certain distance from the sound source. To determine the 50% threshold received sound exposure level (SEL) of an…
Predictions from harbor porpoise habitat association models are confirmed by long-term passive acoustic monitoring
Brookes, Kate L.; Bailey, Helen; Thompson, Paul M.
The Journal of the Acoustical Society of America (2013)
Survey based habitat association models provide good spatial coverage, but only a snapshot in time of a species' occurrence in a particular area. A habitat association model for harbor porpoises…
Clicking in a Killer Whale Habitat: Narrow-Band, High-Frequency Biosonar Clicks of Harbour Porpoise (Phocoena phocoena) and Dall’s Porpoise (Phocoenoides dalli)
Kyhn, Line A.; Tougaard, Jakob; Beedholm, Kristian; Jensen, Frants H.; Ashe, Erin; Williams, Rob; Madsen, Peter T.
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,…
Evaluation of immune and stress status in harbour porpoises (Phocoena phocoena): can hormones and mRNA expression levels serve as indicators to assess stress?
Müller, Sabine; Lehnert, Kristina; Seibel, Henrike; Driver, Jörg; Ronnenberg, Katrin; Teilmann, Jonas; van Elk, Cornelius; Kristensen, Jakob; Everaarts, Eligius; Siebert, Ursula
BMC Vet Res (2013)
The harbour porpoise is exposed to increasing pressure caused by anthropogenic activities in its marine environment. Numerous offshore wind farms are planned or under construction in the North and Baltic…
Habitat preferences and distribution of the harbour porpoise Phocoena phocoena west of Scotland
Booth, C. G.; Embling, C.; Gordon, J.; Calderan, S. V.; Hammond, P. S.
Marine Ecology Progress Series (2013)
The west coast of Scotland is comprised of complex coastlines and topography, and a range of physical processes influence its coastal marine environment. The region is host to one of…

This paper describes a rare sighting of an anomalously white harbour porpoise (Phocoena phocoena) in the coastal waters of the outer Moray Firth in north-east Scotland. The recording provides the…
Unusual mortality events of harbor porpoise strandings in North Carolina, 1997–2009
Hohn, Aleta A.; Rotstein, David S.; Byrd, Barbie L.
Journal of Marine Biology (2013)
A marked increase in the frequency of harbor porpoises (Phocoena phocoena) stranded in North Carolina in 2005 was declared as an Unusual Mortality Event (UME). Strandings occurred in January through…
To ping or not to ping: The use of active acoustic devices in mitigating interactions between small cetaceans and gillnet fisheries
Dawson, S. M.; Northridge, S.; Waples, D.; Read, A. J.
Endangered Species Research (2013)
Active sound emitters (‘pingers’) are used in several gillnet fisheries to reduce bycatch of small cetaceans, and/or to reduce depredation by dolphins. Here, we review studies conducted to determine how…
