Vliv antropogenních vstupů dusíku na strukturu a funkci ektomykorhizních společenstev smrkových lesů
CHOMA, Michal
The effect of anthropogenic nitrogen (N) inputs on the structure of ectomycorrhizal fungal communities in Norway spruce forests was investigated. With the use of soil DNA amplicon sequencing, ectomycorrhizal communities were described in spruce forests exposed historically to different anthropogenic N deposition and experimental manipulative N treatments. This information was put into context with soil biochemical properties and rates of soil processes involved in C and N cycling in order to reveal possible consequences of ectomycorrhizal community restructuring for soil and ecosystem functioning.
Activity of soil enzymes in the Norway spruce forests attacked by bark beetle
ŠLAJSOVÁ, Petra
Activity of enzymes was investigated in the soils of Norway spruce forests in the Bohemian Forest. The aim of the study was the determintation of the impact of temperature and plants dominant in understorey on the activity of extracellular enzymes in the soils in the watershed of Plešné and Čertovo Lake. The measurement of enzymes activities was conducted using the fluorometric method with model substrates.
