Biodiversity of algae (all groups including Cyanobacteria) from oligotrophic lotic and lentic habitats

Research questions

Algae of freshwaters comprise a high diversity of taxa from various evolutionary affiliations (cyanobacteria to green algae) which are to a large extent specific to particular environmental niches and show specific ecological tolerances / preferences. We hypothesize that pristine habitats comprise the highest number of taxa menaced by habitat alterations. Even within urban areas fountain waters could remain refugia for rare taxa when the ground waters have remained at near natural conditions. Within the WFD the definition of natural reference situations is often problematic since such sites are becoming rare and were completely lost in cultural landscapes. We assume that the study of a wide range of habitats in the Alps defined by large altitudinal, moisture and urbanisation gradients would facilitate the delimitation of taxon specific niches irrespective of their affiliation into sessile / benthic or planktonic alga
