Ejemová, Tereza
The bachelor thesis deals with food ecology of European beaver (Castor fiber) in the the wooded area of Tvrdonice. It examines quantity and quality of usable biomass in the non-growing season, when beavers feed on bark and phloem of woody plants. The main wood species that were studied are: poplar (Populus sp.), willow (Salix sp.), oak (Quercus sp.) and elder (Sambucus sp.). The basis of the methodology is collection enough of woody species and laboratory measurement of volume, weight and content of crude protein in usable biomass. The result is a comparison of biomass in individual trees and determination of their nutritional quality.
