Water level fluctuations play a significant role in linking water and soil environments and shaping littoral zone. The aim of study was to evaluate the physical and chemical features of water as well as light availability in phytolittoral zone in the case of water level rise. Investigations were carried out in deep mesotrophic lake with well-developed charophytes meadow, above which samples were collected (30 stations). In this lake between year 2010 and 2012 water level increased over 1.0 m as a result of intense...

Currently a sharp increase of carbon dioxide content in atmosphere of the Earth is one of the great environmental concerns. It could lead to negative (possibly catastrophic) changes of our planet climate. Experts attribute the rapid and significant increase in anthropogenic CO2 emissions to the number of anticipated causes of this problem, as well as the continuing (also anthropogenic and significant) decrease in the natural storage capacities of this greenhouse gas in terrestrial ecosystems. The rate of increment...
