Scientific Committee Meeting Documents (2008)
(...) During April 1997 the acoustic detector was successfully used to detect vaquitas for the first time. On that occasion we surveyed on a fixed location, aboard an outboard motor…
Functional morphology of the hyolaryngeal complex of the harbor porpoise (Phocoena phocoena): Implications for its role in sound production and respiration
Huggenberger, Stefan; Rauschmann, Michael A.; Oelschläger, Helmut H. A.
Anatomical Record (2008)
In several publications, it was shown that echolocation sound generation in the nasal (epicranial) complex of toothed whales (Odontoceti) is pneumatically driven. Modern hypotheses consider the larynx and its surrounding…
Food habits of finless porpoises Neophocaena phocaenoides in Western Kyushu, Japan
Shirakihara, Miki; Seki, Kenji; Takemura, Akira; Shirakihara, Kunio; Yoshida, Hideyoshi; Yamazaki, Takeshi
Journal of Mammalogy (2008)
We examined the stomach contents of 87 finless porpoises (Neophocaena phocaenoides) in the Ariake Sound–Tachibana Bay area and Omura Bay in western Kyushu, Japan, between 1987 and 1992. Fish (Gobiidae…
Subcellular distribution of trace elements in kidney of a mother–fetus pair of Dall’s porpoises (Phocoenoides dalli)
Yang, Jian; Kunito, Takashi; Anan, Yasumi; Tanabe, Shinsuke; Miyazaki, Nobuyuki
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…
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…
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),…
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…
Habitat preferences and interannual variability in occurrence of the harbour porpoise Phocoena phocoena off northwest Scotland
Marubini, F.; Gimona, A.; Evans, P. G. H.; Wright, P. J.; Pierce, G. J.
Marine Ecology Progress Series (2009)
The harbour porpoise Phocoena phocoena is the most common cetacean around the British Isles, but knowledge of its ecology, habitat preferences and inter-annual variability is still inadequate. Here, sightings collected…
