Water ecosystems of Arctic region are most vulnerable to modern climatic changes, since global biogeochemical processes mostly occur on territories of permafrost zone. This work gives new insights into fundamental research question of how fast organic matter of thawing permafrost can be converted to greenhouse gases which are emitted into the atmosphere (for example, CH4). We aimed to identify microbial response and associated release of CH4 from Arctic lakes in response to temperature increase. We investigated la...

Zooplankton organisms are widely used as indicators of ecosystem changes (Adrian et al., 2009, Nigamatzyanova G., Frolova L., 2017). Both zooplankton and nutrients play an important role in monitoring and assessing water quality by greatly contributing to biological productivity (Vinberg,1960). In the current study, we examined water quality of different types of water bodies of Ob and Erkuta river basins, based on the analysis of zooplankton communities and the concentration of nutrients. 72 species of zooplankto...
