The influence of intensity of agricultural land use on pollinator diversity and abundance
Tomsová, Lucie ; Janovský, Zdeněk (advisor) ; Černá, Kristýna (referee)
Agricultural intensification is one of the main reasons for the decline of biodiversity and ecosystem services in agricultural landscape. One of the ecosystem services is pollination, which helps to preserve the biodiversity of wild plants in cultural landscape and is also vital for production of food, especially fruits and vegetables. Decreasing management intensity could be one of the potential solutions for maintaining sufficient level of pollination in the agricultural landscape. This can be achieved at least on parts of agricultural land. Also, certain areas of cultivated land can be excluded from production in exchange for subsidies for farmers who agree to implement this method. For this reason, the European Union has introduced organic farming and agri- environmental schemes. The aim of the study was to determine whether currently applied low-intensity management is sufficiently effective to protect wild plants, pollinators and their mutual relations. And if so, whether it is due to the decreased management intensity or due to the floral sources available. Another question dealt with is how the effects of organic farming depend on the landscape structure. Results of various studies dealing with this topic were qualitatively compared. Current studies show that organic farming has positive...

The effect of agri-environmental schemes on biodiversity
Vodička, Jan ; Reif, Jiří (advisor) ; Kindlmann, Pavel (referee)
The aim of thesis is summary of current results of scientific publications evaluating effectiveness of agri-environmental measures in the relation to biodiversity. This work deals with this issue in Europe, characterizes the situation in selected European countries and evaluate the effectiveness of compensation schemes and individual measures on selected groups of organisms. It also deals with the factors influencing the effectiveness and methodical approaches of evaluation studies. Results of studies suggest a low to medium efficiency of allover measures for plants and invertebrates and low efficiency for birds. Conversely targeted measures had a high efficiency, but their overall significance was very low due to small proportion of land compared to the horizontal measures.The worst situation was in the Netherlands, in other countries the results were relatively similar.
