Vliv heterogenity prostředí na sukcesní vývoj společenstev malých stojatých vod
DOSTÁLKOVÁ, Eva
Small standing water bodies that support colonization and help the survival of many species are nowadays often under threat. Since relationships between species and environments are often complex and not fully understood in these systems, this literature review has been written and a mesocosm experiment has been carried out in order to identify main mechanisms driving community assembly in habitats differing in complexity. I investigated the influence of artificial vegetation and clay on the community composition over a period of time. I found that a turbid environment (with clay) was not suitable for predators. This corresponds to our finding that in these environments, prey groups should be better developed, although the environment is different for each species.
Impact of abiotic factors on community assembly of freshwater insect and other invertebrates in small standing water bodies.
DOSTÁLKOVÁ, Eva
This thesis discusses the abiotic factors that influence conditions for community assembly of water invertebrates organisms in small water reservoirs. The aim of this thesis was to compare the role of and interaction among main abiotic factors for the assembly process. In addition, main biotic factors playing role in community structuring are reviewed and the possibilities of abiotic factors to affect them are discussed. The thesis further reviews abiotic properties that affect colonizator?s habitat choice and summarizes their implication for community assembly.
