Biology & ecology of a killer whale (Orcinus orca) community that interacts with pelagic trawlers in the Northeast Atlantic
Observations of killer whales (Orcinus orca) aggregating around pelagic fishing vessels operating offshore during the autumn/winter Northeast Atlantic mackerel (Scomber scrombrus) fishery, have been documented in the literature since the 1970s. However, baseline information on the biology and …

Isolation and Genomic Analysis of the Cetacean Y-chromosome
… sorting or microdissection is reported for the killer whale (Orcinus orca). Microdissected Y-chromosomes from the killer whale and bottlenose dolphin (Tursiops truncatus) were screened for sequences containing microsatellite motifs. 15 and 10 male-specific microsatellites were identified from …

Echolocation in wild killer whales (Orcinus orca)
Echolocation by odontocete whales has been demonstrated in captive settings many times, yet little is known about its use and function in the wild. In this thesis, I describe echolocation sounds in pods of killer whales (Orcinus orca) off the coasts of British Columbia and Alaska. I examine the …

Vocalizing Behavior in Killer Whales (Orcinus orca) – an Evolutionary Account
… in his biolinguistic account of language, with killer whale (Orcinus orca) vocalizations and what we call the orca vocalization and orca symbolic vocalization systems. We postulate hypothetical orca counterparts of the elements of language described in Chomsky’s account and trace out the …

Orchestration : the movement and vocal behavior of free-ranging Norwegian killer whales (Orcinus orca)
… information content flowing between individuals. Killer whales are likely to acquire traits culturally based on their population-specific feeding behaviors and group-distinctive vocal repertoires. I used digital tags to explore the contributions of individual Norwegian killer whales to group …

Maintaining contact : design and use of acoustic signals in killer whales, Orcinus orca
… signals produced by free-ranging resident killer whales. The analysis focuses on signal features that might be useful for animals to maintain contact and coordinate activities with preferred associates, including: distinctiveness by group or individual, call amplitude, and directionality …

Dialect Use Within a Socially Fluid Group of Southern Resident Killer Whales, <i>Orcinus orca</i>
<p>Resident killer whales, <em>Orcinus orca</em>, of the Northeastern Pacific form stable kinship-based matrifocal associations and communicate with group-specific repertoires of discrete calls (dialects) that reflect these associations. The gradual fission of matrilines is usually consistent with …
