Can we see a cohort effect on survival of Steller sea lions ( Eumetopias jubatus) at Kozlova Cape rookery (eastern Kamchatka, Russia)?
Abstract Steller sea lions ( Eumetopias jubatus ) have experienced a decline in Russia as well as the United States. The causes for the decline of the Russian population may or may not overlap the causes of the decline in Alaska. The demographics of the Russian population are not well understood and...
