NAMMCOSP (2003)
The known geographical distribution (based on ship surveys, aerial surveys, incidental sightings, stranding and bycatch data) and the population genetic structure obtained from mitochondria DNA and nuclear DNA (isozymes and…
Molecular analyses of the truei and dalli morphotypes of Dall’s porpoise (Phocoenoides dalli)
Escorza-Treviño, S.; Pastene, L. A.; Dizon, A. E.
Journal of Mammalogy (2004)
The taxonomic status of the 2 morphologically distinct forms of Dall's porpoises, Phocoenoides dalli (dalli- and truei-type) remains unresolved. To address this uncertainty, mitochondrial DNA (mtDNA) sequences were used to…
Natural hybridization between Dall’s porpoises (Phocoenoides dalli) and harbour porpoises (Phocoena phocoena)
Willis, Pamela M; Crespi, Bernard J; Dill, Lawrence M; Baird, Robin W; Hanson, M Bradley
Can. J. Zool. (2004)
Natural hybridization occurs rarely in mammals compared with other taxonomic groups of animals. Cetaceans appear unique among mammals in exhibiting striking karyological uniformity, which suggests that they have the potential…
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…
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…
Population structure of nuclear and mitochondrial DNA variation among South American Burmeister’s porpoises (Phocoena spinipinnis)
Rosa, Sabrina; Milinkovitch, Michel C.; Van Waerebeek, Koen; Berck, Jehanne; Oporto, Jorge; Alfaro-Shigueto, Joanna; Van Bressem, Marie-Françoise; Goodall, Natalie; Cassens, Insa
Conservation Genetics (2005)
Little is known about the biology of Burmeister’s porpoises (Phocoena spinipinnis), a small cetacean species endemic to South American waters. Information on stock structure, however, is urgently needed, as the…
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…
Population structure and historical demography of eastern North Atlantic harbour porpoises inferred through mtDNA sequences
Tolley, K. A.; Rosel, P. E.
Marine Ecology Progress Series (2006)
The harbour porpoise Phocoena phocoena experiences high rates of incidental mortality in commercial fisheries, and in some areas these rates are sufficiently high to justify concern over population sustainability. Given…

Intermingling of dalli-type Dall’s porpoises into a wintering truei-type population off Japan: Implications from color patterns
Amano, Masao; Hayano, Azusa
Marine Mammal Sci (2007)
There are two major color morphs, truei and dalli types, of the Dall's porpoise and the latter includes two minor morphs. A small number of dalli types are found among…
