Functional diversity in ecological communities
 Džamba, Roman ; Hořák, David (advisor) ; Doležal, Jiří (referee)
Functional diversity is an important component of biodiversity. Value and range of functional traits and the number and composition of functional types are crucial for the short and long term functioning of ecosystems. Functional traits of species affect their performance in ecosystems and we can classify them as continuous or discontinuous. It has been suggested many ways to choose the appropriate traits and functional differences between species in estimating functional diversity. It is necessary to consider the nature and importance of ecosystem processes and environmental factors and consider properties of employed methodological approaches. There are many ways to estimate functional diversity. Functional diversity can be expressed by the number of functional groups, functional index or functional dendrograms. In natural communities, we see a positive relationship between species and functional diversity. Species diversity doesn't seem to be an adequate surrogate for functional diversity because the loss of an equal number of species may have different effects on the ecosystem, depending on the identity of the species. Functional redundancy refers to the functional similarity in the ecological niches occupation and is a source of stability in the ecosystem functioning.
