Ecological and Biochemical Evaluation of the Environment of Modern Foraminifers of the White Sea

摘要

Current ecological conditions in the regions of Bol'shoi Keretskii raid and Glubokaya Salma (Kandalaksha Bay, White Sea) were evaluated on the basis of structural and dynamic indices of the upper sediments in the context of specific composition of the benthic foraminiferal community. The distribution of the main species of living foraminifers was determined for the shallow and deep-sea groups. The relationship between populations of the most abundant species of living benthic foraminifers and hydrolytic enzyme activities providing for destruction of bottom organic matter at biochemical rates has been revealed.
