Chemosphere (2008)
Total and subcellular renal Zn, Cu, Se, Mn, V, Hg, Cd and Ag were determined by a mother–fetus pair of Dall’s porpoises (Phocoenoides dalli). All element concentrations in the maternal…
First case of a monitored pregnancy of a harbour porpoise (Phocoena phocoena) under human care
Blanchet, Marie-Anne; Nance, Tiffany; Ast, Colleen; Wahlberg, Magnus; Acquarone, Mario
Aquatic Mammals (2008)
Most of the data collected on the reproduction of harbour porpoises (Phocoena phocoena) comes from by-caught or stranded animals and is therefore opportunistic in nature. Harbour porpoises kept in a…
Emission of social sounds by marine animals
Au, W. W. L.; Hastings, M. C.
Principles of Marine Bioacoustics (2008)
(...) Sound emissions by odontocetes (toothed whales and dolphins) can be classified into two broad categories of frequency-varying continuous tonal sounds referred to as whistles and broadband clicks (Evans, 1967),…
Click train patterns of free-ranging harbour porpoises acquired using T-PODs may be useful as indicators of their behaviour
Koschinski, S.; Diederichs, A.; Amundin, M.
Journal of Cetacean Research and Management (2008)
Harbour porpoise signals consist of directional, high frequency stereotypic clicks which can be logged using T-PODs. Variation in interclick intervals (ICIs) can be used to distinguish different acoustic behaviours. So…
Changes in the occurrence of common dolphins, striped dolphins and harbour porpoises in the English Channel and Bay of Biscay
MacLeod, Colin D.; Brereton, Tom; Martin, Clive
Journal of the Marine Biological Association of the United Kingdom (2008)
Regular monitoring of the status of cetacean populations is essential for conservation, policy and management. By using a passenger ferry as a scientific research platform, this study provides information on…
Rehabilitation and homing behavior of a satellite-tracked harbor porpoise (Phocoena phocoena)
Schofield, David T.; Early, Greg; Wenzel, Frederick W.; Matassa, Keith; Perry, Cindi; Beekman, Gerry; Whitaker, Brent; Gebhard, Erika; Walton, Wendy; Swingle, Mark
Aquatic Mammals (2008)
A yearling male harbor porpoise (Phocoena phocoena) stranded alive on the shores of Avon, North Carolina, and was rehabilitated for nearly 10 mo at the National Aquarium in Baltimore and…
Characterisation of harbour porpoise (Phocoena phocoena) habitat in German waters
Gilles, A.
Doctoral Thesis - Christian-Albrechts-Universität zu Kiel (2008)
The harbour porpoise (Phocoena phocoena) is an important top predator and as such an indicator species for its environment. Before the beginning of the 21st century, little data existed on…
Diurnal and tidal variations in habitat use of the harbour porpoise (Phocoena phocoena) in southwest Britain
Goodwin, Lissa
Aquatic Mammals (2008)
With the United Kingdom required to designate Special Areas of Conservation (SACs) under Natura 2000 by 2012, it is important to understand site-specific activity and habitat use in order to…
Effect of two levels of masking noise on the hearing threshold of a harbor porpoise (Phocoena phocoena) for a 4.0 kHz signal
Kastelein, Ronald A.; Wensveen, Paul J.
Aquatic Mammals (2008)
The 50% detection hearing thresholds of a harbor porpoise for a 4.0 kHz narrow-band FM signal, presented at the background noise level in a pool and with two masking noise…
Changes in click source levels with distance to targets: Studies of free-ranging white-beaked dolphins Lagenorhynchus albirostris and captive harbour porpoises Phocoena phocoena
Atem, Ana Carolina G.; Rasmussen, Marianne H.; Wahlberg, Magnus; Petersen, Hans C.; Miller, Lee A.;
Bioacoustics (2009)
Probably all odontocetes use echolocation for spatial orientation and detection of prey. We used a four hydrophone “Y” array to record the high frequency clicks from free-ranging White-beaked Dolphins Lagenorhynchus…
