Influence of developmental rate on behavioral personality forming
SCHMIDTMAJEROVÁ, Eva
The aim of this thesis was to empirically examine one of the theories regarding the laws of intraspecific variability in animal behavior, which assumes that differences in behavior are directly related to individual differences in the rate of growth. One of our most common rodents, common vole (Microtus arvalis) was chosen as a model species, mainly because lots of previous studies on this species have demonstrated, among other things, presence of consistent differences in behavior.
Effect of substrate on the production of earthworms Dendrobena veneta
SCHMIDTMAJEROVÁ, Eva
The importance of biological processes for processing of organic wastes is widely acknowledged. My thesis focuses on one of the most efficient methods for conversion of organic wastes into precious products, which are at the same time environmentally friendly. Vermicomposting includes complex food webs and simultaneously modifies various chemical forms of basic nutrients into inorganic compounds, useful for plant nutrition. The thesis briefly describes biology, distribution and basic ecological categories of earthworms and shows their importance in decomposition organic wastes. I describe here the main earthworm species and then concentrate on Dendrobaena veneta. I then compare 5 substrates from the point of view of their suitability for production of this earthworm species and of the suitability of the resulting substrate as fertilizer. I have found that the best substrate for production of Dendrobaena veneta was the output of a sewarage plant and pure celulose.
