Metals in diet of Bering Sea walrus: Mya sp. as a possible transmitter of elevated cadmium and other metals Metals in diet of Bering Sea walrus: Mya sp. as a possible transmitter of elevated cadmium and other metals
Elevated levels of cadmium in Pacific walrus (Odobenus rosmarus divergens) and northern fur seals (Callorhinus ursinus) have been reported in populations from the Bering Sea (Goldblatt & Anthony, 1983; Taylor et al., 1989). Russian and US authorities are concerned because of the possible health hazards from consuming pinniped meat harvested for subsistence peoples. The effects of cadmium...

The marine snail, Cerithidea californica, matures at smaller sizes where parasitism is high The marine snail, Cerithidea californica, matures at smaller sizes where parasitism is high
I investigated life-history and parasitism in the salt marsh snail, Cerithidea californica. Latitude and growing conditions were important factors determining maturation size. After accounting for environmental variation, there was a negative association between the maturation size of snails and the prevalence of parasitic castration by larval trematodes. As predicted by life-history...

Reproductive characteristics of female sea otters Reproductive characteristics of female sea otters
Several important aspects of reproduction in the female sea otter, such as gestation, pupping frequency, period of pup dependency, and annual pupping rate, were unclear when this study was begun. We present data from 75 tagged adult females that indicate gestation is variable, but on average is about 6 months, the length of pup dependency is 6 mo, thus the pupping interval is usually 12...
