The mitochondrial DNA control region of 12 finless porpoises (Neophocaena phocaenoides) from the Yangtze River, Yellow Sea, and South China Sea, was amplified. Two portions, 317 and 245 base pairs,…
Uncertainty about the magnitude of various risks facing endangered species can paralyze conservation action. The vaquita is a naturally rare porpoise that has declined to the low hundreds of individuals…
The vaquita, Phocoena sinus, is one of two critically endangered cetacean species, and is listed as an endangered species in both the United States and Mexico. These listings result from…
The harbour porpoise (Phocoena phocoena) is subject to a high rate of incidental mortality in fisheries worldwide and, in some areas, these rates are sufficiently high to warrant concern over…
A 60-cm female fetus recovered from a Dall's porpoise (Phocoenoides dalli) found dead in southern British Columbia was fathered by a harbour porpoise (Phocoena phocoena). This is the first report…
The population structure of harbour porpoises from British and adjacent waters was studied by examining variability in a 200 bp (base pair) section of the control region of mitochondrial DNA…
We used 11 restriction endonucleases to study mtDNA variation in 101 Dall's porpoises Phocoenoides dalli from the Bering Sea and western North Pacific. There was little phylogeographic patterning among the…
Portions of the cytochrome b gene and control region of the mitochondrial DNA molecule were sequenced to investigate systematic relationships among the six extant species of true porpoises, (Cetacea: Phocoenidae).…
At the meeting of the IWC Scientific Committee held in Dublin in May 1995, the special topic addressed by the sub-committee on small cetaceans was the North Atlantic harbour porpoise.…
Genetic variability and differentiation of three families containing 12 species of toothed whales mainly from the sea around Japan have been examined by starch-gel electrophoresis at 19 genetic loci encoding…
