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…
A review of methods for defining population structure in the harbour porpoise (Phocoena phocoena)
Lockyer, Christina
NAMMCOSP (2003)
Wide-ranging methods that have been used to determine population structure, including distribution, life history, biology, ecological factors such as diet and contaminant loads, morphology and genetics, are reviewed. The importance…
