KEY WORDS: Jellyfish · Distribution · Food consumption · Ecosystem changes · Bering Sea. in the Bering Sea have been confounded by the presence of a congener, Kamchatka Flounder (Atheresthes evermanni: KF), which occurs mostly in the western Bering Sea but also in the eastern Bering Sea and Aleutian Islands. Visual identification between these two species is possible for adults, but not for larval or early juvenile stages.

The Pacific walrus population for example, virtually all of which is found in the Bering Sea during the mating season, splits up as the pack ice retreats northwards in April-May, mostly females and juveniles following the ice to the southern edge of the Chukchi Sea.
Aug 01, · Abstract. Five species of pagophilic (ice-loving) pinnipeds live in the Bering and Chukchi seas: Odobenus rosmarus, Phoca (Pusa) hispida, Phoca (Histriophoca) fasciata, an ice-breeding population of Phoca (Phoca) vitulina, and Erignathus barbatus.
Breeding adults of these species are mostly separated from each other during late winter and early spring, when, throughout the pupping Cited by: Discusses the adaptation, evolution, classification, distribution, ecology, behavior, communication, and learning of seals, sea lions and walruses.

Analyses of the most abundant marine bird species in the eastern Bering Sea indicate that their distribution and abundance are the result of complex interactions between biotic and abiotic elements of the environment.
Of particular importance are the effects of ice systems, food availability, oceanographic frontal systems, and the location of suitable nesting sites. status of all known vertebrate species in the Bering Sea, we hope to alleviate this situation by calling attention to the full range of species of concern in the Bering Sea, highlighting species about which we lack sufﬁcient infor-mation, and providing a scientiﬁc basis for improving conservation of the precious wildlife of the Bering Sea.
