متن کاملBELUGA WHALE, Delphinapterus leucas: Cook Inlet Population - Critically Endangered
Population Identity: Based on studies of mitochondrial DNA, Cook Inlet belugas are genetically distinct from the other four beluga populations that occur in western and northern Alaska (O’Corry-Crowe et al. 1997; O’Corry-Crowe, pers. comm.). There have been only two beluga sightings recorded in the region between Cook Inlet and the nearest beluga population in Bristol Bay (Frost and Lowry 1990;...
متن کاملMigratory culture, population structure and stock identity in North Pacific beluga whales (Delphinapterus leucas)
The annual return of beluga whales, Delphinapterus leucas, to traditional seasonal locations across the Arctic may involve migratory culture, while the convergence of discrete summering aggregations on common wintering grounds may facilitate outbreeding. Natal philopatry and cultural inheritance, however, has been difficult to assess as earlier studies were of too short a duration, while geneti...
متن کاملBeluga whale (Delphinapterus leucas) vocalizations and call classification from the eastern Beaufort Sea population.
Beluga whales, Delphinapterus leucas, have a graded call system; call types exist on a continuum making classification challenging. A description of vocalizations from the eastern Beaufort Sea beluga population during its spring migration are presented here, using both a non-parametric classification tree analysis (CART), and a Random Forest analysis. Twelve frequency and duration measurements ...
متن کاملThe Genome of the Beluga Whale (Delphinapterus leucas)
The beluga whale is a cetacean that inhabits arctic and subarctic regions, and is the only living member of the genus Delphinapterus. The genome of the beluga whale was determined using DNA sequencing approaches that employed both microfluidic partitioning library and non-partitioned library construction. The former allowed for the construction of a highly contiguous assembly with a scaffold N5...
