Perception of low-frequency acoustic signals by a harbour porpoise (Phocoena phocoena) in the presence of simulated offshore wind turbine noise

Lucke, Klaus; Lepper, Paul A.; Hoeve, Bert; Everaarts, Eligius; van Elk, Niels; Siebert, Ursula
Aquatic Mammals (2007)

Using auditory evoked potential (AEP) methods, a study was conducted on a harbour porpoise (Phocoena phocoena) at the Dolfinarium Harderwijk in The Netherlands. The study measured the audible range of…

Behavioral responses of a harbor porpoise (Phocoena phocoena) to 25.5- to 24.5-kHz sonar down-sweeps with and without side bands

Kastelein, Ronald A.; van den Belt, Ivanka; Gransier, Robin; Johansson, Torbjörn
Aquatic Mammals (2015)

Signals used in naval and long-range fish detec­tion sonar often contain harmonics which may influence the behavior of harbor porpoises (Phocoena phocoena) more than the lower fun­damental frequencies, so the…

Behavioral responses of a Harbor porpoise (Phocoena phocoena) to 25-kHz FM sonar signals

Kastelein, Ronald A.; van den Belt, Ivanka; Helder-Hoek, Lean; Gransier, Robin; Johansson, Torbjörn
Aquatic Mammals (2015)

The effects of three sonar sound types (peak frequency ca. 25 kHz with high-frequency side bands at 71 and 121 kHz) on the behavior of a harbor porpoise (Phocoena phocoena)…

Predation of harbour porpoises (Phocoena phocoena) by grey seals (Halichoerus grypus) in Wales

Stringell, Thomas; Hill, Dave; Rees, Dafydd; Rees, Ffion; Rees, Padrig; Morgan, Greg
Aquatic Mammals (2015)

(...)Grey seals are generalist feeders, taking a wide variety of fish, mollusc, echinoderm, crustacean, and cephalopod prey (Bowen & Harrison, 1994; Hammond et al., 1994; Strong, 1996; Brown et al.,…

Determining genotypes from blowhole exhalation samples of harbour porpoises (Phocoena phocoena)

Borowska, Ewa I.; Nowak, Zuzanna; van Elk, Cornelis; Wahlberg, Magnus
Aquatic Mammals (2014)

(...) It is currently not known if DNA could be obtained from blowhole exhalations of smaller- toothed whales, such as harbour porpoises, with much smaller exhalation volumes than bottlenose dolphins.…

Effect of series of 1 to 2 kHz and 6 to 7 kHz up-sweeps and down-sweeps on the behavior of a harbor porpoise (Phocoena phocoena)

Kastelein, Ronald; Schop, Jessica; Gransier, Robin; Steen, Nele; Jennings, Nancy
Aquatic Mammals (2014)

To compare the effect of naval sonar up-sweeps and down-sweeps on the behavior of harbor porpoises, a harbor porpoise in a large pool was exposed to simulated low- and mid-frequency…

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…

Records of harbour porpoises (Phocoena phocoena) in fishing nets during the interwar period in Poland: Verification of archival materials

Psuty, Iwona
Aquatic Mammals (2013)

The Polish fisheries administration registered incidents of harbour porpoises caught by fishermen from fishing bases within the country's borders between 1922 and 1938. These data are unique in the Baltic…
