Dialect Use Within A Socially Fluid Group Of Southern Resident Killer Whales, Orcinus Orca, Courtney Elizabeth Smith
Master's Theses
Resident killer whales, Orcinus orca, 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 dialect variations among groups that may manifest as differences in call usage at the repertoire level or subtle structural differences of the calls themselves. Therefore, matrilines that are more closely related tend to be more acoustically similar. Within the endangered community of Southern Resident killer whales (SRKWs), recent evidence shows that one particular group (L pod) exhibits the lowest rate of intrapod association …
