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…
Phylogeography of the finless porpoise (genus Neophocaena): testing the stepwise divergence hypothesis in the northwestern Pacific
Lin, Wenzhi; Frère, Céline H.; Karczmarski, Leszek; Xia, Jia; Gui, Duan; Wu, Yuping
Scientific Reports (2014)
We used 344 mitochondrial control region (717 bp) sequences from the finless porpoise (genus Neophocaena) from the northwestern Pacific to investigate the extent and manner in which past climatic oscillations may…
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…
Revision of the taxonomy of finless porpoises (genus Neophocaena): the existence of two species
Jefferson, Thomas A.; Wang, John Y.
Journal of Marine Animals and Their Ecology (2011)
Due to extensive morphological variation and inadequately-sampled or poorly-designed studies, the taxonomy of the finless porpoises (genus Neophocaena) has been controversial for some time. An uneasy stability with the arrangement…
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,…
Auditory temporal resolution and evoked responses to pulsed sounds for the Yangtze finless porpoises (Neophocaena phocaenoides asiaeorientalis)
Mooney, T. Aran; Li, Songhai; Ketten, Darlene R.; Wang, Kexiong; Wang, Ding
J Comp Physiol A (2011)
Temporal cues are important for some forms of auditory processing, such as echolocation. Among odontocetes (toothed whales, dolphins, and porpoises), it has been suggested that porpoises may have temporal processing…
A questionnaire survey on the distribution of the finless porpoise, Neophocaena phocaenoides, in Japanese waters
Shirakihara, Kunio; Yoshida, Hideyoshi; Shirakihara, Miki; Takemura, Akira
Marine Mammal Sci (1992)
(...) The finless porpoise (Neophocaena phocaenoides) shows a decidedly inshore distribution pattern (Kasuya and Kureha 1979), occurring in coastal waters frequented by fishermen. Its lack of a beak and a…
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…
The first Yangtze finless porpoise successfully born in captivity
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…
Ex-situ conservation status of an endangered Yangtze finless porpoise population (Neophocaena phocaenoides asiaeorientalis) as measured from microsatellites and mtDNA diversity
XIA, J; ZHENG, J; WANG, D
ICES Journal of Marine Science (2005)
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…
