DD ChangE – Diverzita a distribúcia druhov a spoločenstiev v meniacom sa prostredí
Diversity and distribution of species and communities in changing environment
Program: VEGA
Zodpovedný riešiteľ: Mgr. Šibíková Mária PhD.
Annotation: Spatio-temporal changes translate to changes in diversity and distribution of populations and communities across all organizational levels, influencing many aspects of biota. Shifts in distribution of plant communities and species including invasions by alien species gained significance in past decades when this phenomenon became more evident. Now it is obvious that the main drivers and causes of changes in diversity and distribution include 1) land use and management; 2) climate change; 3) spreading of alien species and 4) natural disturbances. Combinations of these factors influence vegetation, agroecosystems and forestry either in negative or positive way. Identifying general pattern at local scales, in various habitats, and differentiation of effects caused by each driver will help us to understand the impact of observed changes and their role in ecosystems. To reach our goals we focus on habitats from the basins to the alpine belt – floodplains, montane forests, grassland and alpine communities.

Diverzita rastlín jelšových lesov hlavných bioregiónov strednej Európy
Diversity of plant understory of alder forests in the main bioregions of Central Europe
Program: VEGA
Zodpovedný riešiteľ: Ing. Hrivnák Richard PhD.
Annotation: Alder forests with dominance of Alnus glutinosa are ecologically and floristically specific vegetation type. These forests belong to the endangered vegetation and they are under strong human pressure in Central Europe. We focus on the study of plant diversity patterns (alpha, beta and gamma) in the main Central European bioregions (Alpine, Continental and Pannonian) with respect to various plant groups (vascular plants, bryophytes, native and alien species) and two types of these forests, riparian alder forests and alder carrs. In addition, we would like to detect which ecological factors (including human impact) have an impact on alpha diversity of plants and which conditions predeterminate the highest species richness.

Druhová bohatosť synúzie vyšších rastlín bukových lesov pozdĺž výškového gradientu
Species richness of vascular plants in undestory of beech forests along altitudinal gradient
Program: VEGA
Zodpovedný riešiteľ: RNDr. Valachovič Milan DrSc.
Annotation: Beech forests represent the most widespread forest vegetation type in Slovakia with an important sientific and socio-economic value. Species richness trend of vascular plants along altitudinal gradient reflects strong competitive ability of the European beech. The project is focused on i) species richness-altitudinal relationship at various spatial scales, and ii) potential factors controlling this interaction.
