Abstract

We have studied the state of the zooplankton community of Lake Sevan in present-day climatic conditions at a relatively stable water level. The taxonomic composition is poor but retains features that were characteristic of this lake even before the beginning of the artificial lowering of the water level (1938) for energy and irrigation purposes. The lake is mesotrophic in zooplankton development indicators, but in some years a low transparency and high values of zooplankton biomass are observed, which is characteristic of eutrophic reservoirs. This is a consequence of an increase in water level and aY possible increase in water temperature under climate change.

全球气候变化背景下塞凡湖浮游动物研究作为生态系统稳定性指标

摘要

我们研究了当前气候条件下相对稳定的水位下塞凡湖浮游动物群落的状况。分类组成很差，但保留了该湖的特征，甚至在出于能源和灌溉目的而人为降低水位（1938年）之前。该湖浮游动物发育指标为中营养性，但某些年份浮游动物生物量透明度较低，数值较高，这是富营养化水库的特征。这是气候变化下水位上升和水温可能上升的结果。
