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…
Distribution of Dall’s porpoise, Phocoenoides dalli, in the North Pacific and Bering Sea, based on T/S Oshoro Maru 2012 summer cruise data
Suzuki, Sachiko; Sekiguchi, Keiko; Mitani, Yoko; Onishi, Hiroji; Kamito, Takehiko
Zoological Science (2016)
Dall's porpoise (Phocoenoides dalli) is a small toothed cetacean, widely inhabiting the North Pacific Ocean and adjacent seas, between about 30 and 62°N; however, only limited studies of its ecology…
Polybrominated diphenyl ethers (PBDEs) and their hydroxylated and methoxylated analogues in the blood of harbor, Dall’s and finless porpoises from the Japanese coastal waters
Ochiai, Mari; Nomiyama, Kei; Isobe, Tomohiko; Yamada, Tadasu K.; Tajima, Yuko; Matsuda, Ayaka; Shiozaki, Akira; Matsuishi, Takashi; Amano, Masao; Iwata, Hisato; Tanabe, Shinsuke
Marine Environmental Research (2016)
This study investigated the accumulation of polybrominated diphenyl ethers (PBDEs) and their hydroxylated and methoxylated analogues (OH-PBDEs and MeO-PBDEs) in the blood of harbor porpoises, Dall's porpoises, and finless porpoises…
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…
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…
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:…
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…
Sexual dimorphism of Dall’s porpoise and harbor porpoise skulls
Frandsen, Marie Schou; Galatius, Anders
Mammalian Biology - Zeitschrift für Säugetierkunde (2013)
To evaluate and quantify sexual dimorphism of skull shape and assess the ontogenetic background for differences, samples of 134 harbor porpoise (Phocoena phocoena) and 85 Dall's porpoise (Phocoenoides dalli) were…
Morphology and variation in porpoise (Cetacea: Phocoenidae) cranial endocasts
Racicot, Rachel A.; Colbert, Matthew W.
The Anatomical Record (2013)
Evolution of endocranial anatomy in cetaceans is important from the perspective of echolocation ability, intelligence, social structure, and alternate pathways for circulation to the brain. Apart from the importance of…
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…
