the effect of organohalogen contaminants on western steller sea lion survival and movement in the russian far east.the western stock of steller sea lions (eumetopias jubatus) have experienced dramatic declines since the 1960s, particularly in the western alaskan and asian portions, which have continued to decline or stabilized at low levels. multiple causes for this decline have been proposed and may include anthropogenic contamination from organohalogen contaminants (ocs). these include polychlorinated biphenyls (pcbs) and dichlorodiphenyltrichloroethane (ddt), which have not been ruled out as a potential c ...201424887189
age specific survival rates of steller sea lions at rookeries with divergent population trends in the russian far east.after a dramatic population decline, steller sea lions have begun to recover throughout most of their range. however, steller sea lions in the western aleutians and commander islands are continuing to decline. comparing survival rates between regions with different population trends may provide insights into the factors driving the dynamics, but published data on vital rates have been extremely scarce, especially in regions where the populations are still declining. fortunately, an unprecedented ...201526016772
