Marine Technology Society Journal (2005)
To observe the bio-sonar behavior of dolphins and porpoises, a miniature stereo acoustic data logger was developed to record the echolocation clicks of small cetaceans. The 'A-tag' device is small…
Parentage determination of an isolated Yangtze finless porpoise population Neophocaena phocaenoides asiaeorientalis in the Yangtze Tian-e-Zhou Baiji National Natural Reserve based on molecular data
Junhong, Xia; Jinsong, Zheng; Limei, Xu; Ding, Wang
Progress in Natural Science (2005)
Reproductive behaviors are poorly known for the Yangtze finless porpoise Neophocaena phocaenoides asiaeorientalis. In this study, the parentage of an isolated Yangtze finless porpoise population inhabiting the Yangtze Tian-e-Zhou Baiji…

WANG, Ding; HAO, Yujiang; WANG, Kexiong; ZHAO, Quingzhong; CHEN, Daoquang; WEI, Zhuo; ZHANG, Xianfeng
Environmental Science and Pollution Research (2005)
As the sole freshwater subspecies of finless porpoise (Neophocaena phocaenoides), the Yangtze finless porpoise (N. p. asiaeorientalis) lives only in the middle and lower reaches of the Yangtze River and…
Reproductive seasonality and maturity of male Neophocaena phocaenoides asiaeorientalis in captivity: A case study based on the hormone evidence
Daoquan, Chen; Yujiang, Hao; Qingzhong, Zhao; Ding, Wang
Marine and Freshwater Behaviour and Physiology (2006)
To provide hormone evidence on reproductive seasonality and maturity of the Yangtze finless porpoise, the authors monitored the monthly variations of serum reproductive hormones of a male Yangtze finless porpoise…
Review on breeding biology of Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis)
Hao, Yujiang; Wang, Ding; Zhang, Xianfeng
Acta Theriologica Sinica (2006)
There are three Neophocaena phocaenoides subspecies recognized in Chinese waters: South China Sea population, N. p. phocaenoides; Yellow Sea population, N. p. sunameri; and Yangtze population, N. p. asiaeorientalis. The…

Fresenius Environmental Bulletin (2006)
Mercury concentrations in some key tissues (liver, kidney, small intestine, stomach, blubber and brain) of five Yangtze finless porpoises (Neophocaena phocaenoides asiaeorientalis), accidentally died in the Eastern Dongting Lake of…
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,…
Geographical distribution of polybrominated diphenyl ethers (PBDEs) and organochlorines in small cetaceans from Asian waters
Kajiwara, Natsuko; Kamikawa, Satoko; Ramu, Karri; Ueno, Daisuke; Yamada, Tadasu K.; Subramanian, Annamalai; Lam, Paul K. S.; Jefferson, Thomas A.; Prudente, Maricar; Chung, Kyu-Hyuck; Tanabe, Shinsuke
Chemosphere (2006)
Polybrominated diphenyl ethers (PBDEs) are one of the flame retardants widely used in plastics, textiles, electronic appliances, and electrical household appliances. In this study, PBDEs and organochlorine compounds (OCs) were…
Distribution and abundance of finless porpoise in the Inland Sea of Japan
Shirakihara, Kunio; Shirakihara, Miki; Yamamoto, Yoshiteru
Marine Biology (2006)
Aerial sighting surveys were conducted in 2000 to evaluate the distribution and abundance of finless porpoise Neophocaena phocaenoides in the Inland Sea of Japan. We flew 60 north–south transects (2,218…
Comparison of echolocation behaviour between coastal and riverine porpoises
Akamatsu, Tomonari; Teilmann, Jonas; Miller, Lee A.; Tougaard, Jakob; Dietz, Rune; Wang, Ding; Wang, Kexiong; Siebert, Ursula; Naito, Yasuhiko
Deep Sea Research Part II: Topical Studies in Oceanography (2007)
Echolocation behaviour of a harbor porpoise and six finless porpoises was recorded in open-water systems using acoustic data loggers (A-tag). In total 1359 click trains were recorded during 4.6 h…
