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 کاملBlue Whales Respond to Anthropogenic Noise
Anthropogenic noise may significantly impact exposed marine mammals. This work studied the vocalization response of endangered blue whales to anthropogenic noise sources in the mid-frequency range using passive acoustic monitoring in the Southern California Bight. Blue whales were less likely to produce calls when mid-frequency active sonar was present. This reduction was more pronounced when t...
متن کاملImmune functions in beluga whales
Natural killer (NK) activity, an important non-specific defense mechanism against viral infections and tumors, was demonstrated in beluga whales using two different methods: “‘Cr release and flow cytometry. Using the “Cr release assay, NK activity in belugas was shown to be higher against K-562 than against YAC-1 cell lines. Moreover, it was enhanced by the addition of human recombinant interle...

متن کاملSpatial modeling of haul-out site use by harbor seals in Cook Inlet, Alaska
Harbor seals Phoca vitulina haul out on land to give birth to and rear their pups, rest, escape aquatic predation and molt. The choice of a haul-out site is therefore fundamental to survival and reproduction. Aerial surveys of harbor seals were conducted in Cook Inlet, Alaska, to investigate the seals’ selection of various environmental characteristics of haul-out sites. Eight surveys from Apri...
