Application of a developed high-throughput community analysis toolset to describe the spatial and temporal dynamics of aquatic mycoplankton communities
Aquatic fungi are a highly diverse ecological group of organisms adapted to survive in a variety of aquatic habitats ranging from alpine rivers to coral reefs and from arctic lakes to deep sea sediments. Though highly abundant and diverse in many aquatic ecosystems, there are still many gaps in our...

Aquatic fungi are a highly diverse ecological group of organisms adapted to survive in a variety of aquatic habitats ranging from alpine rivers to coral reefs and from arctic lakes to deep sea sediments. Though highly abundant and diverse in many aquatic ecosystems, there are still many gaps in our knowledge and understanding about what is shaping their community structure, distribution, and dispersal patterns. In addition, little is known about their role in the biogeochemical and carbon cycles and their position in the microbial loop and food web structures. A limiting reason was the lack of an adequate toolkit for an easy and high-throughput description of aquatic fungal communities. Therefore, the aim of my dissertation was to develop missing tools such as a primer tool and a pipeline for the analysis of fungal high-throughput 18S rRNA gene sequence datasets and to test them for ecological questions involving the spatio-temporal resolution of mycoplankton communities. In Chapter I, I present a primer toolkit consisting of a comprehensive list of 18S rRNA gene sequence primer pairs of various characteristics in respect to amplicon length, total fungal coverage, specificity on fungal taxa, and prevention of co-amplification from other eukaryotic groups.
