Antarctic fur seals are relatively convenient for studying the molecular genetics of pigmentation for three main reasons. First, they aggregate ashore in large numbers during the breeding season, allowing sufficient numbers of hypopigmented individuals to be sampled for genetic analysis despite their rarity.

A new life table is compiled for the northern fur seal, Callorhinus ursinus, of the Pribilof Islands, Alaska. The population is assumed to be reasonably stable on the basis of (1) similar estimates for pup production in the late nineteen-seventies, after the apparent low of 1969 1970, and in 1963 when the herd reduction program ended; (2 Population models are reviewed to reveal trends in the study and management of the northern fur the nonlinear nature of density-dependent population regulation, (3) extension of density-dependent effects Reexamination of the life table for northern fur seals with implications about population regulatory mechanisms.

Such distributed regulatory networks are common in biological and engineered systems. The regulatory output is an emergent property of the entire system. Experimentally, it is possible to amplify one or more of the individual mechanisms to affect sleep, e.g. Injection of a SRS or stimulation of a sleep regulatory circuit. Pursuant to the regulations governing the subsistence taking of northern fur seals, this document summarizes the annual fur seal subsistence harvests on St. George and St. Paul Islands (the Pribilof Islands) for 2002 to 2004 and proposes annual estimates of fur seal subsistence needs for 2005 through 2007 on the Pribilof Islands, Alaska. the northern fur seal (Callorhinus ursinus) population of St. Paul Island, Alaska.
