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…


Habitat-based cetacean density models for the U.S. Atlantic and Gulf of Mexico

Roberts, Jason J.; Best, Benjamin D.; Mannocci, Laura; Fujioka, Ei; Halpin, Patrick N.; Palka, Debra L.; Garrison, Lance P.; Mullin, Keith D.; Cole, Timothy V. N.; Khan, Christin B.; McLellan, William A.; Pabst, D. Ann; Lockhart, Gwen G.
Scientific Reports (2016)

Cetaceans are protected worldwide but vulnerable to incidental harm from an expanding array of human activities at sea. Managing potential hazards to these highly-mobile populations increasingly requires a detailed understanding…


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…


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,…


Ultrastructure of enamel and dentine in extant dolphins (Cetacea: Delphinoidea and Inioidea)

Loch, Carolina; Duncan, Warwick; Simões-Lopes, Paulo C.; Kieser, Jules A.; Fordyce, R. Ewan
Zoomorphology (2012)

Longitudinal and cross sections of teeth from 17 species of the Recent dolphins (Delphinoidea and Inioidea) were examined under scanning electron microscope to study the arrangement and ultrastructure of dental…


Odontocetes of the Southern Ocean Sanctuary

Van Waerebeek, K.; Leaper, R.; Baker, A. N.; Papastavrou, V.; Thiele, D.; Findlay, K.; Donovan, G.; Ensor, P.
Journal of Cetacean Research and Management (2010)

Twenty-eight odontocete species were identified as occupying sub-Antarctic and Antarctic habitat covered by the 1994 IWC-established Southern Ocean Sanctuary. Toothed whales evidently play an important part in the Antarctic polar…


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…
