Phenotypic plasticity of selected species of aquatic insects
 DUDOVÁ, Pavla
Phenotypic plasticity is the ability of the single genotype to pruduce multiple phenotypes in response to evironmental conditions. There are many factors affecting phenotypic plasticity. The aim of this thesis is to summarize the current knowledge of phenotypic plasticity of aquatic insects with emphasis on the role of temperature and food availability. The review is complemented by a laboratory experiments designed to investigate the effect of temperature and food availability on growth and development rate of diving beetle Acilius canaliculatus (Coleoptera: Dytiscidae). The results are discussed in the light of the ecological concepts of temperature-size rule and developmental isomorphy.

The effect of experience on the frequency-dependent food selectivity of predatory aquatic insects.
 DUDOVÁ, Pavla
The aim of this thesis is to evaluate current knowledge of predation in aquatic insects in the light of optimal foraging theory and switching. I explain these two phenomena and discuss how they can be connected to explain frequency-dependent prey selection. The review is complemmented by laboratory experiments on the effect of experience on frequency-dependent food selectivity of larvae of dragonflies (Odonata).
