Journal of Cetacean Research and Management (2008)

A vessel-based line-transect survey conducted during February 2004 along 1,018km of systematic trackline in the nearshore waters of Bangladesh resulted in 111 ‘on-effort’ cetacean sightings including: Irrawaddy dolphins, Orcaella brevirostris…


Predation by killer whales (Orcinus orca) and the evolution of whistle loss and narrow-band high frequency clicks in odontocetes

Morisaka, T.; Connor, R. C.
Journal of Evolutionary Biology (2007)

A disparate selection of toothed whales (Odontoceti) share striking features of their acoustic repertoires including the absence of whistles and high frequency but weak (low peak-to-peak source level) clicks that…

Environmental Pollution (2006)

Polybrominated diphenyl ethers (PBDEs) and organochlorine compounds (OCs) were determined in the blubber of male finless porpoises (Neophocaena phocaenoides) collected in 1990 and 2000/01 from the South China Sea. Among…


The phylogenetic relationships and biogeography of true porpoises (Mammalia: Phocoenidae) based on morphological data

Fajardo-Mellor, Liliana; Berta, Annalisa; Brownell, Robert L.; Boy, Claudia C.; Goodall, R. Natalie P.
Marine Mammal Sci (2006)

Prior studies of phylogenetic relationships among phocoenids based on morphology and molecular sequence data conflict and yield unresolved relationships among species. This study evaluates a comprehensive set of cranial, postcranial,…


Polybrominated diphenyl ethers (PBDEs) and organochlorines in small cetaceans from Hong Kong waters: Levels, profiles and distribution

Ramu, Karri; Kajiwara, Natsuko; Tanabe, Shinsuke; Lam, Paul K.S.; Jefferson, Thomas A.
Marine Pollution Bulletin (2005)

Polybrominated diphenyl ethers (PBDEs) and organochlorine compounds (OCs) were determined in the blubber, liver and kidney of Indo-Pacific humpback dolphins (Sousa chinensis) and finless porpoises (Neophocaena phocaenoides) stranded in Hong…
