Sažetak
The northern Adriatic is characterized by particularly steep ecological gradients over space and time. Some of those gradients are strongly connected to benthic pelagic coupling, like e.g. the sudden availability of nutrients during the onset of water column mixing. Living species have to adapt to abiotic processes in the ecosystem and of course to processes in benthic pelagic coupling. However, they also play an active role in the mechanisms driving benthic pelagic coupling. The analysis of aggregates in the water column and the metabolic activity of planktonic species in and around those aggregates exemplifies the danger of generalization, black box approaches and again the need for in situ observations. It also demonstrates how the borders between benthic and pelagic life can be crossed in both directions. To understand adaptations to and active roles in such processes, meticulous in situ observations are of pivotal importance. The large variability in phytoplankton species (and other pelagic species) stands in strong contrast to the apparent continuity and lack of structure of their environment. However, research on phytoplankton life strategies, in particular with regard to competition for nutrients, unveils a rather rich structure of the pelagic ecosystem and a correspondingly rich variability of life strategies. Such rich variability can be found for interactions between different planktonic organisms as well. Food preference as well as grazing efficiency of planktonic and benthic species vary throughout their lifecycle already and showcase the complexity of the biology behind benthic pelagic coupling.
