High-altitude freshwater lakes are experiencing ever-increasing risk of harmful algal blooms (HABs) on the face of climate change and a growing demand on agricultural production. The biggest alpine lake of the Caucasus, Lake Sevan, has “blooming” recently almost every year. Thus, the study of phytoplankton community’ development patterns in Lake Se...
Lake Sevan, Armenia, is the largest freshwater body in the Caucasus region. Cyanobacteria have become increasingly dominant in summer in Lake Sevan, reflecting the eutrophication of the lake and formed a massive bloom event in 2018. These recent observations mark the transition of this previously oligotrophic high mountain lake into a eutrophic lak...
A study of the horizontal and vertical distribution of phytoplankton in Lake Sevan was conductedin mid-July 2018 during the maximum Cyanoprokaryota blooms. The summer biomass of algae in the pelagiczone of the lake corresponded to values of mesatrophic waters. The Cyanoprokaryota biomass in Lake Sevanhas horizontal and vertical heterogeneity and is...
The current status of phytoplankton community in Lake Sevan (LS) was investigated. Water samples for phytoplankton and mineral phosphorus analyses were collected seasonally (spring–fall) in 2018. The results of the study showed that the unstabilized processes and nutrient pollution of the lake ecosystem led to bluegreen algae bloom in July. All of...
Based on the results of many years of comprehensive research conducted by the Institute of Hydroecology and Ichthyology of the National Center of Zoology and hydroecology of the National Academy of Sciences of the Republic of Armenia, quantitative and qualitative indicators of water in the lake were studied as a necessary condition for the preventi...
