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…
Comparative anatomy of the bony labyrinth of extant and extinct porpoises (Cetacea: Phocoenidae)
Racicot, Rachel A.; Gearty, William; Kohno, Naoki; Flynn, John J.
Biological Journal of the Linnean Society (2016)
The inner ear anatomy of cetaceans, now more readily accessible by means of nondestructive high-resolution X-ray computed tomographic (CT) scanning, provides a window into their acoustic abilities and ecological preferences.…
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…
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…
Bigg’s (transient) killer whale predation on Dall’s porpoise (Phocoenoides dalli) and harbour porpoise (Phocoena phocoena)
McInnes, Josh D.; Cullen, Kelsey D.; Browne, Lynette M.; Dehalt, Annette; Templeman, Nick M.
Technical Report for the Royal British Columbia Museum (2015)
(...) Two separate predation events were documented off the coast of Vancouver Island, British Columbia between the years 2013-2014. Both predation events occurred on small cetaceans from the Phocoenidae family:…
Updated marine mammal distribution and abundance estimates in British Columbia
Best, B. D.; Fox, C. H.; Williams, R.; Halpin, P. N.; Paquet, P. C.
Journal of Cetacean Research and Management (2015)
Information relating to the distribution and abundance of species is critical for effective conservation and management. For many species, including cetacean species of conservation concern, abundance estimates are lacking, out…
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…
Accumulation of hydroxylated polychlorinated biphenyls (OH-PCBs) and implications for PCBs metabolic capacities in three porpoise species
Ochiai, Mari; Nomiyama, Kei; Isobe, Tomohiko; Mizukawa, Hazuki; Yamada, Tadasu K.; Tajima, Yuko; Matsuishi, Takashi; Amano, Masao; Tanabe, Shinsuke
Chemosphere (2013)
The present study investigated polychlorinated biphenyls (PCBs) and hydroxylated metabolites of PCBs (OH-PCBs) in blood from three porpoise species: finless porpoises (Neophocaena phocaenoides), harbor porpoises (Phocoena phocoena), and Dall’s porpoises…
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…
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,…
