Problems of the north

Problems of the North no.11 is devoted to the biological and ecological bases for the proper utilization, reestablishment, and conservation of wildlife (fur-bearing animals, marine mammals, fish and game birds). It contains much original data on the biology and ecology of individual species (including the polar bear, arctic fox, wild reindeer, and mountain sheep). This research work is also of importance with respect to zoo-geography. A substantial part of this issue is devoted to marine mammals and problems associated with the harvesting of marine mammals.
