Canadian Journal of Zoology (1993)
We studied development and sexual dimorphism in external measurements of Dall's porpoises (Phocoenoides dalli) from the northwestern North Pacific. Relative rates of increase in the measurements of the head and…
Predation by killer whales (Orcinus orca) and the evolution of whistle loss and narrow-band high frequency clicks in odontocetes
Morisaka, T.; Connor, R. C.
Journal of Evolutionary Biology (2007)
A disparate selection of toothed whales (Odontoceti) share striking features of their acoustic repertoires including the absence of whistles and high frequency but weak (low peak-to-peak source level) clicks that…
Comparison of dolphins’ body and brain measurements with four other groups of cetaceans reveals great diversity
Ridgway, Sam H.; Carlin, Kevin P.; Van Alstyne, Kaitlin R.; Hanson, Alicia C.; Tarpley, Raymond J.
Brain, Behavior and Evolution (2016)
We compared mature dolphins with 4 other groupings of mature cetaceans. With a large data set, we found great brain diversity among 5 different taxonomic groupings. The dolphins in our…
Harbor porpoise (Phocoena phocoena) recovery in the inland waters of Washington: Estimates of density and abundance from aerial surveys, 2013–2015
Jefferson, Thomas A.; Smultea, Mari A.; Courbis, Sarah S.; Campbell, Gregory S.
Canadian Journal of Zoology (2016)
The harbor porpoise (Phocoena phocoena (L., 1758)) used to be common in Puget Sound, Washington, but virtually disappeared from these waters by the 1970s. We conducted systematic aerial line-transect surveys…
Abundance and distribution of cetaceans in the Gulf of Alaska
Rone, Brenda K.; Zerbini, Alexandre N.; Douglas, Annie B.; Weller, David W.; Clapham, Phillip J.
Marine Biology (2017)
To effectively protect and manage marine mammals, contemporary information on their abundance and distribution is essential. Several factors influence present-day insight including the accessibility of the study area and the…
Sound production by a neonatal Dall’s porpoise (Phocoenoides dalli)
Bain, David E.
Proceedings of the 16th Annual IMATA Conference (1988)
-San Antonio, Texas- In July of 1987, a Dall's porpoise (Phocoenoides dalli), with her umbilical cord still attached, stranded in Bodega Bay, California. She was transported to Marine World Africa,…
Studies on echolocation of porpoises taken in salmon gillnet fisheries
Hatakeyama, Yoshimi; Soeda, Hideo
Sensory Abilities of Cetaceans (1990)
(...)In the Bering Sea, marine mammals, particularly Dall's porpoises, Phocoenoides dalli, get incidentally entangled in gillnets of the Japanese mothership salmon fishery. The maximum total number of Dall's porpoises to…
Asymmetry of the nasofacial skull in toothed whales (Odontoceti)
Huggenberger, S.; Leidenberger, S.; Oelschläger, H. H. A.
Journal of Zoology (2016)
In this study, the nasal asymmetry of odontocetes (toothed whales) was analyzed morphometrically by placing landmarks on photographed nasofacial skulls from 12 different species and genera that belong to four…
Cetacean distribution and abundance in relation to oceanographic domains on the eastern Bering Sea shelf, June and July of 2002, 2008, and 2010
Friday, Nancy A.; Zerbini, Alexandre N.; Waite, Janice M.; Moore, Sue E.; Clapham, Phillip J.
Deep Sea Research Part II: Topical Studies in Oceanography (2013)
As part of the Bering Sea Project, cetacean surveys were conducted to describe distribution and estimate abundance on the eastern Bering Sea shelf. Three marine mammal observers conducted visual surveys…
Feeding habits of Dall’s porpoises (Phocoenoides dalli) in the subarctic North Pacific and the Bering Sea basin and the impact of predation on mesopelagic micronekton
Ohizumi, Hiroshi; Kuramochi, Toshiaki; Kubodera, Tsunemi; Yoshioka, Motoi; Miyazaki, Nobuyuki
Deep Sea Research Part I: Oceanographic Research Papers (2003)
We investigated the stomach contents of Dall's porpoises collected in pelagic waters spanning most of their range in the North Pacific and the Bering Sea. Analysis revealed the porpoises fed…
