Life strategies of harmful planktonic algae (with respect to phosphate limitation) in marine environments

While bloom formation is associated with nutrient availability, bloom manteinence and the general life strategy of harmful algae have to cope with nutrient limitations. Phosphate limitation is a general phenomenon in marine ecosystems and a predicted global trend. The northern Adriatic (Mediterranean) is an interesting ecosystem to study life strategy adaptations to phosphate limitation. It is characterized by steep gradients of nutrient availability and thus allows the comparison of harmful algae in-situ behavior in correlation with a large range of culture experiments reflecting in situ conditions. In earlier studies we found that alkaline phosphatase extracellular activity as well as membrane lipid remodeling are major reactions of phytoplankton to phosphate limitations. However, each species is using those functions in its own way to ensure survival and success within the phytoplankton community. Having identified phosphate limitation as a major shaping factor we here present how harmful algae species of the genera Pseudo-nitzschia H.Peragallo, 1900 and Skeletonema Greville, 1865 ensure successful competition within the phytoplankton community. We discuss how the derived life strategies explain the spatiotemporal distribution of those harmful species. Recent results suggest a large range of species specific strategies to cope with P- stress.
