(...) Some of the observations mentioned in this paper have been made at sea, on board the oceanographic vessel Calypso, put at our disposal by a special committee of the…
The diel rhythms of biosonar behavior in the Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) in the port of the Yangtze River: The correlation between prey availability and boat traffic
Wang, Zhitao; Akamatsu, Tomonari; Wang, Kexiong; Wang, Ding
PLoS ONE (2014)
Information on the habitat use of the critically endangered Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) is critical for its conservation. The diel biosonar behavior of the porpoise in the port…
Will harbour porpoises (Phocoena phocoena) habituate to pingers?
Cox, T. M.; Read, A. J.; Solow, A.; Tregenza, N.
Journal of Cetacean Research and Management (2001)
Large bycatches of harbour porpoises (Phocoena phocoena) occur in gillnet fisheries throughout the Northern Hemisphere. Several mitigation measures, including acoustic deterrent devices or ‘pingers’, have been used in efforts to…
Functional morphology and homology in the odontocete nasal complex: Implications for sound generation
Cranford, T. W.; Amundin, M.; Norris, K. S.
Journal of Morphology (1996)
The site and physiologic mechanism(s) responsible for the generation of odontocete biosonar signals have eluded investigators for decades. To address these issues we subjected postmortem toothed whale heads to interrogation…
Characterization of the temporomandibular joint of the harbour porpoise (Phocoena phocoena) and Risso’s dolphin (Grampus griseus)
McDonald, M.; Vapniarsky-Arzi, N.; Verstraete, F.J.M.; Staszyk, C.; Leale, D.M.; Woolard, K.D.; Arzi, B.
Archives of Oral Biology (2015)
Objectives The temporomandibular joint (TMJ) in cetaceans is largely uncharacterized. This study aims to describe the macroscopic, microscopic, biochemical and biomechanical features of the TMJ of two species of the…
The ontogeny of echolocation in a Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis)
Li, Songhai; Wang, Ding; Wang, Kexiong; Xiao, Jianqiang; Akamatsu, Tomonari
The Journal of the Acoustical Society of America (2007)
Acoustic and concurrent behavioral data from one neonatal male Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis) in captivity were presented. The calf click train was first recorded at 22 days postnatal,…
Dall porpoise, Phocoenoides dalli (True): Observations in captivity and at sea
Ridgway, S.H.
Norsk Hvalfangst-Tidende (1966)
The Dall porpoise Phocoenoides dalli is common in south central California waters from October through June. During the summer months it is not commonly found farther south than about 35°.…
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…
Scanning sonar of rolling porpoises during prey capture dives
Akamatsu, T.; Wang, D.; Wang, K.; Li, S.; Dong, S.
Journal of Experimental Biology (2009)
Dolphins and porpoises have excellent biosonar ability, which they use for navigation, ranging and foraging. However, the role of biosonar in free-ranging small cetaceans has not been fully investigated. The…
An adult-like sonar wave shape from a rehabilitated orphaned harbour porpoise (Phocoena phocoena)
Kamminga, C.; Engelsma, F.J.; Terry, R. P.
Ophelia (1999)
In July 1989, a lone male harbour porpoise (Phocoena phocoena), estimated to be no more than a few days old, was found stranded on the coast near Newport, Oregon, USA.…
