Eutrophication represents one of the most impacting threats for ecological status and related ecosystem services transitional waters; hence, its assessment plays a key role in management these ecosystems. A new multi-index method eutrophication assessment, based on index MaQI (Macrophyte Quality Index), trophic TWQI (Transitional Water physicochemical quality elements (sensu Dir. 2000/60/EC), w...

Theory suggests that variation in the attractive solvation force associated with cell-surface hydrophobicity can significantly affect contact rates among small cells in aqueous environments and consequently may influence rates and selective impacts of marine nanoflagellate grazers feeding on picoplankton assemblages. To investigate this hypothesis, we assayed the natural range in hydrophobic ch...

Due to the great climatic variety and the peculiar north-south orographic distribution, Argentinean lake systems include a wide diversity of aquatic environments. The deepest lakes are situated in the Patagonian Andes and Tierra del Fuego, and range from ultraoligotrophic to oligotrophic. Patagonian Plateau lakes are shallower than Andean lakes and usually range from mesotrophic to eutrophic. A...
