Abundance and distribution of pacific walrus Odobenus rosmarus divergens in vicinity of Cape Serdtse-Kamen in 2009-2013
Results of the first special research of pacific walrus Odobenus rosmarus divergens at Cape Serdtse-Kamen conducted in the 2009-2011 and 2013 are presented. The coastal haulout place looks as series of relatively isolated areas (up to 36) located alongshore about 20 km from Cape Serdtse-Kamen to the...
