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.

Zmeny biodiverzity v urbánne fragmentovanej krajine
Changes in biodiversity in an urban fragmented landscape
Program: VEGA
Zodpovedný riešiteľ: Ing. Čejka Tomáš PhD.
Annotation: The project deals with changes in biodiversity in an urban environment in two ways: in the space (ecological gradients, fragmentation of habitats) and time (historical data). For study, we chose two ecologically linked model groups: vascular plants and land snails. Based on the research of these model organisms, we will solve five main points: [1] How the urban fragmented woodland fits principles of the island biogeography and what is the impact of the fragmentation and env. variables on the biota structure and variability. [2] Whether and to what extent the genetic diversity of the populations of selected model species varies in long-term continuously forested areas comparing the neorefugia; [3] How the urban environment impacts in time and space on the diversity of indigenous species; [4] On the basis of the theory of refugia verify what is the ecol.l traits structure of biota in the remains of forest vegetation; [5] Whether biotic homogenization occurs and which groups of biota are most affected by biotic homogenisation.
