Diverzita a disperzia v metapopuláciách a metaspoločenstvách malých vodných biotopov
Diversity and dispersal in metapopulations and metacommunities of small aquatic biotopes
Program: VEGA
Zodpovedný riešiteľ: RNDr. Čiamporová – Zaťovičová Zuzana PhD.
Annotation: Project is aimed at small aquatic biotopes, very important regarding their biodiversity, yet often overlooked and understudied. Project is logically linked to previous projects of team members. Proposed is reasonable improvement of datasets on communities of natural biotopes in lowland and mountain regions, new data will be acquired on human impacted areas, including robust environmental data. Macrophytes, molluscs, zooplankton and aquatic insects were chosen as model groups due to their indication value, different ecological requirements and function in food webs. Main goal is to understand patterns of biological diversity of small water bodies, emphasizing 1) evaluation of the importance of different biotope types for biodiversity preservation, 2) assessment of dispersal and habitat features roles in metacommunity structure and 3) describing extent of connectivity within metapopulations. Reaching the goals will improve effective conservation of aquatic ecosystems – important component of global environment.

Funkčná a taxonomická diverzita mokradí a ich vzťah k ekosystémovým procesom
Functional and taxonomic diversity of wetlands and their relationship to ecosystem processes
Program: APVV
Zodpovedný riešiteľ: Ing. Hrivnák Richard PhD.
Annotation: Functional diversity is a component of biodiversity that generally concerns the range of things that organisms doin ecosystems. The relationship between taxonomic and functional diversity is virtually unknown in the most ofecosystems. The proposed project is focused on functional biodiversity of wetland communities and itsrelationship with taxonomic diversity and ecosystem processes. Proposed project is based on the study of threeecosystem processes of key importance in wetlands: decomposition rate, primary productivity and invasibility.Pond-dwelling communities of plant and macroinvertebrates are proposed here as a model system for theresearch with the following aims:1) To evaluate the effect of environment and diversity (functional and taxonomic) on ecosystem processes2) To assess the response of taxonomic and functional diversity to human influence
