The Yangtze finless porpoise, Neophocaena phocaenoides asiaeorientalis, is an endangered small cetacean that occurs only in the middle and lower reaches of the Yangtze River of China. The establishment of…
Population genetic structure of the Yangtze Finless Porpoise (Neophocaena phocaenoides asiaeorientalis): Implications for management and conservation
Zheng, Jin-Song; Xia, Jun-Hong; He, Shun-Ping; Wang, Ding
Biochem Genet (2005)
Understanding the population genetic structure is a prerequisite for conservation of a species. The degree of genetic variability characteristic of the mitochondrial DNA control region has been widely exploited in…
Construction of ethogram of the captive Yangtze finless porpoises, Neophocaena phocaenoides asiaeorientalis
Xiao, J.; Wang, D.
Acta Hydrobiologica Sinica (2005)
Quantitative study of behavior should be preceded by precise description and definition of behavior. Therefore, an ethogram, which includes the comprehensive descriptions of the characteristic behavior of a species, should…
New stereo acoustic data logger for free-ranging dolphins and porpoises
Akamatsu, Tomonari; Matsuda, Akihiko; Suzuki, Shiro; Wang, Ding; Wang, Kexiong; Suzuki, Michihiko; Muramoto, Hiroyuki; Sugiyama, Naoki; Oota, Katsunori
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…
Neophocaena phocaenoides
Jefferson, T.A.; Hung, S.K.
Mammalian Species (2004)
(...) Neophocaena phocaenoides is the only member of the family Phocoenidae without a dorsal fin (Fig. I ). In its place is a low, geographically-variable dorsal ridge (sometimes inappropriately called…
Comparative anatomical study on the relationships between the vestigial pelvic bones and the surrounding structures of finless porpoises (Neophocaena phocaenoides)
Tajima, Yuko; Hayashi, Yoshihiro; Yamada, Tadasu K.
Journal of Veterinary Medical Science (2004)
Morphology of the modern cetaceans represents the results of adaptation of the ancestral terrestrial mammals to aquatic life through their evolutional processes. Some of the primitive fossil cetaceans are known…
Review of small cetaceans: Distribution, behaviour, migration and threats
Culik, Boris
(2004)
This report summarises the available knowledge on odontocete (toothed whale) distribution, behaviour, migration and threats and was compiled for the Bonn Secretariat of CMS.
Abundance estimate of finless porpoises off the Pacific coast of eastern Japan based on aerial surveys.
Amano, Masao; Nakahara, Fumio; Hayano, Azusa; Shirakihara, Kunio
Mammal Study (2003)
We carried out an aerial survey to estimate the abundance of finless porpoises Neophocaena phocaenoides off the Pacific coast of eastern Japan between Sendai Bay (38°23’N) and the mouth of…
Mitochondrial control region variability of baiji and the Yangtze finless porpoises, two sympatric small cetaceans in the Yangtze river
Yang, Guang; Liu, Shan; Ren, Wenhua; Zhou, Kaiya; Wei, Fuwen
Acta Theriologica (2003)
Baiji Lipotes vexillifer (Miller, 1918) and the Yangtze finless porpoise Neophocaena phocaenoides asiaeorientalis (Pilleri and Gihr, 1972) are two sympatric small cetaceans inhabiting the middle and lower reaches of the…
Preliminary analysis of geographic variation in cranial morphometrics of the finless porpoise (Neophocaena phocaenoides)
Jefferson, T. A.
The Raffles Bulletin of Zoology (2002)
The taxonomy of the finless porpoise (Neophocaena phocaenoides), while better-studied than that of many species of small cetaceans, still suffers from some uncertainties and a general lack of data from…
