Small cetaceans are by-caught in salmon gillnet fisheries in British Columbia (BC) waters. In Canada, there is currently no generic calculation to identify when management action is necessary to reduce…
Use of organochlorines as chemical tracers in determining some reproductive parameters in Dalli-type Dall’s porpoise Phocoenoides dalli
Subramanian, AN.; Tanabe, Shinsuke; Tatsukawa, Ryo
Marine Environmental Research (1988)
Persistent organochlorines (PCBs and p,p′-DDE) in the bodies of dalli- and truei-type Dall's porpoises (Phocoenoides dalli) from the Bering Sea and the northwestern North Pacific were used as chemical tracers…
Population structure and intergeneric hybridization in harbour porpoises Phocoena phocoena in British Columbia, Canada
Crossman, CA; Barrett-Lennard, LG; Taylor, EB
Endangered Species Research (2014)
We used variation at microsatellite loci and in mitochondrial DNA (mtDNA) to detect and quantify (1) hybridization between the harbour porpoises Phocoena phocoena and the Dall’s porpoises Phoconoides dalli and…
Clicking in a Killer Whale Habitat: Narrow-Band, High-Frequency Biosonar Clicks of Harbour Porpoise (Phocoena phocoena) and Dall’s Porpoise (Phocoenoides dalli)
Kyhn, Line A.; Tougaard, Jakob; Beedholm, Kristian; Jensen, Frants H.; Ashe, Erin; Williams, Rob; Madsen, Peter T.
PLoS ONE (2013)
Odontocetes produce a range of different echolocation clicks but four groups in different families have converged on producing the same stereotyped narrow band high frequency (NBHF) click. In microchiropteran bats,…
Geographic variation and sexual dimorphism in the skull of Dall’s porpoise, Phocoenoides dalli
Amano, Masao; Miyazaki, Nobuyuki
Marine Mammal Sci (1992)
Two hundred and eighty-nine skulls of Dall's porpoises from the North Pacific Ocean, Sea of Japan, Sea of Okhotsk, and Bering Sea were investigated morphometrically. A clear pattern of geographic…
Phylogeography, intraspecific structure and sex-biased dispersal of Dall’s porpoise, Phocoenoides dalli , revealed by mitochondrial and microsatellite DNA analyses
Escorza-Treviño, S.; Dizon, A. E.
Molecular Ecology (2000)
Mitochondrial DNA (mtDNA) control-region sequences and microsatellite loci length polymorphisms were used to estimate phylogeographical patterns (historical patterns underlying contemporary distribution), intraspecific population structure and gender-biased dispersal of Phocoenoides dalli…
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…
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,…
Age, growth, and reproductive patterns of Dall’s porpoise (Phocoenoides dalli) in the central north Pacific ocean
Ferrero, Richard C.; Walker, William A.
Marine Mammal Sci (1999)
Life history parameters were estimated for Dall's porpoise, Phocoenoides dalli, from biological specimens collected in the western Aleutian Islands, during 1981–1987. Of 2,033 males and 3,566 females examined, reproductive data…
Seasonal patterns in the abundance and distribution of California cetaceans, 1991-1992
Forney, Karin A.; Barlow, Jay
Marine Mammal Sci (1998)
This study presents a detailed seasonal comparison of the abundance and distribution of cetaceans within 100-150 nmi (185-278 km) of the California coast during 1991 and 1992. The results of…
