The Fragility of Coastal Freshwater Resources in the Mediterranean Area - a Microbial-based Case Study of Lake Vrana

Mediterranean freshwater systems (coastal lakes or springs) as scarce water resources are experiencing an increase in anthropogenic and climate change-caused pressures, leading to increased productivity and consequent deterioration of the trophic state [1]. Coastal lakes are centers of carbon circulation and transformation managed to a large degree by microbial populations intertwined in a network of interactions [2]. The trophic state of the coastal Lake Vrana is under the influence ofseveral counteracting drivers. In the summer months, at least 50% of the surface area is covered by macrophytes [3] that utilize large amounts of nutrients and thereby mitigate eutrophication. On the other hand, the largest agricultural complex in the region with the water discharge system feeding into the lake and excessive water pumping at local springs can considerably enhance the natural eutrophication process[4]. High-throughput sequencing of 16S and 18S rRNA genes revealed the effect of several environmental pressures on the microbial community structural change, including salinity, and dissolved organic carbon (DOC) concentrations. While the connection between microbial primary producers and heterotrophic bacteria was deciphered through DOM perturbation, the lake’s precipitation-evaporation imbalance caused the seawater intrusion and the introduction of marine species and allochthonous DOM input.
