Mechanisms of phytoplankton succession across steep spatio-temporal nutrient gradients in the northern Adriatic

The northern Adriatic (NA) is an ideal basin to study the adaptive strategies of plankton to a variety of conditions along steep spatio - temporal gradients. Earlier studies identified P - limitation as one of the key stresses within the NA that shape the biological response in terms of biodiversity and metabolic responses. A wide range of reports support the notion that P - limitation is a globally important phenomenon in marine ecosystems. In this study, microscopic analysis allowed the determination of phosphorus (P) stress of marine phytoplankton at species level along a trophic gradient in the NA. In P - limitation all species with considerable contributions to the hytoplankton community expressed alkaline phosphatase activity (APA).
