Project title : Diving Deep into the Microscopic Realm of Aquatic Habitats: Biodiversity Assessment of the Enigmatic Phytodiniales (Dinophyceae)

Within the unicellular Dinophyceae (Alveolata), the Phytodiniales are among the groups whose biodiversity is currently the least well researched. While many other Dinophyceae are predominantly planktonic, Phytodiniales are characterised by a mostly immotile lifestyle. In some cases, they exhibit interspecific interactions with other organisms in the form of epiphytism or even parasitism. This project employs a methodologically diverse approach that includes fieldwork, light, fluorescence and electron microscopy, Sanger sequencing, phylotranscriptomics, taxonomy and nomenclature. Material will be collected in a targeted manner, primarily from type localities, many of which are located in the Munich area, or from the ponds of the Nymphenburg Botanical Garden, where dark taxa of the Phytodiniales were already detected in a previous metabarcoding project. The research will be based on self-established unialgal strains, for which optimal ecological conditions for cultivation will be determined in the course of the project. Ideally, phytodinalean species that have been described more than 100 years ago, and rarely observed since then, will be successfully cultivated and studied in detail. It is also highly likely that this pioneering project will identify and describe species still unknown to science, a situation that is not uncommon in the microscopic realm, even in seemingly well-explored regions such as Central Europe.
