Abstract

• Recent studies have assessed that microbial parameters may be used as bioindicators of climate change in the carbon cycle. The carbon fl ux in aquatic environments is ruled by microorganisms that provide both organication and oxidation of the organic matter by means of production and respiration, respectively. Recent studies on the global carbon budget show that not always a coupling between microbial autotrophic and heterotrophic activities exists. Consequently, aquatic environments can act as sink or source of CO2 in relation to productive or degradative processes, respectively. Our working group for more than a decade studying the role of microbial activity in the biogeochimical processes in the deep Mediterranean Sea and in the Antarctic Ocean which are interesting for several search sites. Recently, transitional areas are often studied for resource management and exploitation. Brackish ecosystems are among the most geochemically and biologically active areas of the biosphere and it plays a considerable role in the global biogeochemichal cycle. Some studies have shown that, in lakes with different trophic state, measurements of microbial activities over the organic matter provide ecological information in terms of functional effi ciency of the microbial community that could be useful for resource management. Microorganisms affect signifi cantly the lake biogeochemistry . In fact, owing to their high abundance, biochemical diversity and quick turnover times, they promptly responds to environmental changes and utilize a wide spectrum of nutritional sources. In transitional environments, microbial autotrophic and heterotrophic activities may be balanced or unbalanced in relation to the ecosystem maturity. Consequently, microorganisms can act as sink or source of CO2 in relation to their dominant metabolism, respectively. Nothwithstanding their peculiarities and biodiversity, up to date few research considered microbial community and biogeochemical processes in lagoons that sometimes result characterized by marked diversifi cation of the trophic levels, organic matter turnover and metabolic C budget both at spatial and seasonal scales, with conditions ranging from oligotrophy to eutrophy. The occurrence of seasonal trophic imbalances in these oligotrophic ecosystems confi rm their vulnerability to climate changes. (literal)
