Vliv rostlin s různou ekonomickou strategií na půdní procesy
ŠKOPOVÁ, Kateřina
This bachelor thesis addresses plant-soil interactions through plant litter and living roots, compares the effects of plants with a competitive and conservative resource management strategy on soil and ecosystem functioning. The literature review is followed by a proposal for a scientific project aimed at increasing knowledge of the rhizosphere processes of competitive and conservative species and testing the validity of the hypothesis that competitive species affect their environment more intensively than conservative species.

Interactions between plants and soil biota and effect of energetic crops on these interactions
Heděnec, Petr ; Frouz, Jan (advisor) ; Pergl, Jan (referee) ; Mortimer, Simon (referee)
My PhD thesis is focused on study of plant-soil interactions. Chapter 1 is focused on general introduction to the interactions between plants and soil biota in terms of relationships between soil organisms and aboveground biomass as well as root biomass. Chapter 2 is focused on food interaction of Folsomia candida and soil microscopic fungi (Penicillium chrysogenum, Penicillium expansum, Absidia glauca, and Cladosporium herbarum). Fungi were grown separately on Petri dishes or on different litter type (oak, alder and willow) separately as well. Laboratory experiments showed that food preference was more influenced by different litter types than fungal species. In chapter 3 was studied long-term production of hybrid sorrel and its effect on the composition of the soil meso and macrofauna, basal soil respiration, microbial biomass and composition of cultivable fraction of soil microscopic fungi in comparison with oilseed rape and cultural meadow. There was found that long-term production of hybrid sorrel affects the composition of soil fauna, while the microbial activity of the soil was more affected by agriculture practices, especially tillage. In chapter 4 was studied the effect of native (Salix viminialis and Phalaris arudinacea) and introduced (Reynoutria sachalinensis, Silphium perfoliatum and...
