Traditional knowledge of the ecology of beluga whales (Delphinapterus leucas) in the northern Bering Sea, Chukotka, Russia

The first systematic effort to document traditional ecological knowledge (T EK) of beluga whales (Delphinapterus leucas) in Russia was conducted in the villages of Sireniki, Novoe Chaplino, Yanrakinnot, and Uelen, in the Chuko tka Autonomous Okrug. The findings describe migratory and local movements, feeding, calving, ecological interactions, and human influences on distribu tion and behavior. The results add considerable detail to published account s of belugas in Russian waters of the Bering and Chukchi Seas. Among these are descriptions of avoidance and habituation responses to anthropogenic no ise, which appear to depend in part on association with hunting activities. The authors observe that most of the TEK documented in this study came fro m older hunters, and that the collective pool of traditional knowledge in t he region is disappearing.
