Protists, unicellular eukaryotes, are one of the most diverse (if not the most diverse) group of organisms on the planet and are widely distributed over the eukaryotic tree of live. They exhibit a ubiquitous distribution upon many terrestrial and aquatic ecosystems. Additionally, their ecological roles span across many different trophic modes, from phototrophic primary producers like phytoplankton, to parasites, symbionts and predators, significantly involved into ecological nutrient cycling. In recent years, molecular techniques have unveiled an impressive array of previously unknown protists, changing our perception of their ecological roles and diversity in global ecosystems. The primary aim of the present study was to explore the diversity with regard to taxonomic and functional composition. By combining amplicon sequencing with modern taxonomic methods such as cultivation-based approaches and microscopy, our objective was to expand knowledge of protist diversity in brackish and freshwater habitats. This included exploring the protist communities in their entirety as well as investigating two specific communities closely associated with amphibian species. We selected two regions in the southern Baltic Sea differing in several abiotic factors (Fehmarnbelt and Oderbank), as a model for studying benthic protist communities in brackish-water environments. The study offered novel insights into brackish-water communities, that have not been investigated in this magnitude and might hint at potential correlations between specific protist groups and environmental parameters. This study also has an applied aspect as it was intended to serve as a baseline study to monitor the effect of ground fishing in future. Using a very strictly filtered amplicon sequencing dataset, we found no overlap in taxonomic composition between the two selected regions. While ciliates exhibited remarkable diversity in both regions, marine alveolates belonging to the MALV group displayed the highest read abundances. Previous studies have shown that this group of organisms, with an assumed parasitic life style, is highly abundant in marine environmental datasets, but have not yet been recorded from brackishwater habitats. However, as they are mostly uncultured, not much is known about their ecology. In freshwater environments but also in amphibian hosts, protist parasites and commensals are known to be common. As an example, we wanted to get more insight into the trophic mode of parasitism by investigating the presence of Batrachochytrium dendrobatidis (Bd) and other amphibian parasites in the green toad (Bufotes viridis) and syntopic amphibians. Therefore, we combined DNA metabarcoding with a qPCR survey. The results revealed the presence of Bd in green toad populations, highlighting the potential threat of this deadly pathogen to amphibian populations in the investigated region. Additionally, the study identified other parasitic organisms, mainly protists, inhabiting the gut of the amphibians. As an antagonist to the detrimental effects of the presence of protists in connection with amphibians, we were interested in the occurrence of the unicellular alga Oophila in German breeding waters of Rana dalmatina. The alga is known for its close association with various amphibians, forming a kind of mutualistic relationship. Our study offers valuable insights into the diversity of micro-eukaryotes, with a particular focus on green algae, inhabiting amphibian clutches. Through DNA metabarcoding, we uncovered a wide array of protist taxa colonizing these amphibian egg masses, highlighting the ecological complexity of this specific habitat. Importantly, the study revealed substrate-specific preferences among these protists - clutches are inhabited by a unique protist community. Additionally, we aimed to disentangle parts of the uncertain taxonomy of Oophila, showing that a certain clade is exceptionally frequent in amphibian clutches, also in our investigated specimens. These results emphasize how taxonomic studies play a crucial role in enhancing the accuracy and reliability of public databases used in environmental sequencing studies. Modern taxonomy provides essential reference points for researchers to correctly classify and interpret the vast diversity of genetic sequences encountered in various ecosystems. To highlight this aspect further more, we investigated two taxonomic groups in more detail, to revise and/or expand their taxonomy. The genus Goniomonas (sensu lato) is not only the single taxon of cryptophytes without a plastid, it also shows a deep genetic divergence between the freshwater and marine strains. Even though it is a very frequently observed heterotrophic flagellate, only few species have been described yet, mainly on the basis of morphologic observations. The objective of our study was to revise the genus Goniomonas and offer a suitable Neotype. In the course of the study it became evident that the genus had be be split into several new genera. We based the introduction of Limnogoniomonas gen. nov., Goniomonas and Aquagoniomonas gen. nov., Neptunogoniomonas gen. nov., Marigoniomonas gen. nov, Thalassogoniomonas gen. nov., Poseidogoniomonas gen. nov. and Cosmogoniomonas gen. nov. on both morphological and phylogenetic investigations. The taxonomy of the bicosoecid Cafeteria has been recently revised. With our study we aimed to resolve the species diversity of the genus furthermore, additionally by adding autecological experiments into an integrative taxonomic approach. In this way, we were able to describe several new species of Cafeteria including one from the Baltic Sea. As those sequences are or will deposted in public databases, this thesis shows the close connection between modern taxonomy and environmental sequencing.
