BELUGA 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 کاملEnvironmental Adaptations of the Beluga Whale (Delphinapterus leucas)
This paper aims to analyze the physiological, perceptual, and behavioral adaptations in the Beluga Whale (Delphinapterus leucas) as a result of its arctic niche. The social implications of these adaptations will be examined by looking at each part as influential elements of each other. Lastly, the idea of defining culture in cetaceans will be addressed, including a proposal for examining cultur...
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...
متن کاملPossible mechanisms of action of environmental contaminants on St. Lawrence beluga whales (Delphinapterus leucas).
A small isolated population of beluga whales (Delphinapterus leucas) that are highly contaminated by pollutants, mostly of industrial origin, resides in the St. Lawrence estuary, Québec, Canada. Overhunting in the first half of the century was the probable cause for this population to dwindle from several thousand animals to the current estimate of 500. The failure of the population to recover ...
متن کاملThe effect of sea - ice loss on beluga whales ( Delphinapterus leucas ) in
An aerial survey was conducted to estimate the abundance of belugas (Delphinapterus leucas) on their wintering ground in West Greenland in March–April 2006 and 2008. The survey was conducted as a double platform aerial line transect survey, and sampled approximately 17% of the total survey area of ca. 125 000 km. The abundance of belugas was 10 595 (95% confidence interval 4904–24 650). The lar...
