Heavy metals in the Northern Fur Seal, Callorhinus
ursinus, and Harbor Seal, Phoca vitulina richardi.
This commission was one of many created during the late 19th and early 20th centuries to solve problems with dwindling commercial natural resources such as timber, fisheries, and northern fur seals, Callorhinus
ursinus, (Jordan, 1922; Olson, 1971) and provides a classic example from the Progressive Era (Hays, 1959).
Food of the Pacific white-sided dolphin, Lagenorhynchus obliquidens, Dali's porpoise, Phocoenoides dalli, and northern fur seal, Callorhinus
ursinus, off California and Washington.
On an earlier review of this anomaly in otariids, Acevedo and Aguayo (2008) reported cases in five otariid species: Antarctic fur seal, Arctocephalus gazella (Peter, 1875), Northern fur seal, Callorhinus
ursinus Linnaeus, 1758, Steller sea lion, Eumetopias jubatus (Schreber, 1776), Californian sea lion, Zalophus californianus (Lesson, 1828), and South American sea lion, Otaria flavescens (Shaw, 1800).
groenlandica (harp seals), Callorhinus
ursinus (northern fur seals), Mirounga angustirostris (northern elephant seals), Zalophus californianus (California sea lions), Eumetopias jubatus (steller sea lions), and Otaria flavescens (South American sea lions) (9-13).
The residual flow is northward, but this pass appears to be an important avenue for many migrating marine mammals, particularly fur seals, Callorhinus
ursinus, and gray whales, Eschrichtius robustus, and it appears to be an area of high productivity, given the number of sea bird colonies and whales observed (L.
at least if the parent is Callorhinus
ursinus, the northern fur seal.
It is therefore advantageous for the pup to consume milk as rapidly as possible, as found in northern fur seals Callorhinus
ursinus (Costa and Gentry 1986).
ursinus -- which roughly means 'bear with a beautiful nose' -- has been studied for more than a century, by scores of researchers.
22) A review of the NMFS POP database, which included the NMML pelagic fur seal, Callorhinus
ursinus, program data, yielded 167 harbor porpoise (50 sightings total) north of 50[degrees] N, 135[degrees] W from 1958 to 1968, none of which occurred in Cook Inlet (Fig.
Archived reports from an international controversy in the early 1890s over management of the harvest of fur seals, Callorhinus
ursinus, on the Pribilof Islands in the southeastern Bering Sea provided an unanticipated record of observations on the growth of lichens in association with the prevailing climatic conditions.
What portion of the geographic range of northern fur seals, Callorhinus
ursinus, in the Bering Sea should be protected from the direct effects of fishing during their breeding season?
