                         only a small amount of the Earths water exists as continental 
                         surface water bodies, this compartment plays an important role in 
                         the biogeochemical cycles connecting the land to the atmosphere. 
                         The territory of Brazil encompasses a dense river net and enormous 
                         number of shallow lakes. Human actions have been heavily 
                         influenced by the inland waters across the country. Both 
                         biodiversity and processes in the water are strongly driven by 
                         seasonal fluvial forces and/or precipitation. These macro drivers 
                         are sensitive to climate changes. In addition to their crucial 
                         importance to humans, inland waters are extremely rich ecosystems, 
                         harboring high biodiversity, promoting landscape equilibrium 
                         (connecting ecosystems, maintaining animal and plant flows in the 
                         landscape, and transferring mass, nutrients and inocula), and 
                         controlling regional climates through hydrological-cycle feedback. 
                         In this contribution, we describe the aquatic ecological responses 
                         to climate change in a conceptual perspective, and we then analyze 
                         the possible climate change scenarios in different regions in 
                         Brazil. We also indentify some potential biogeochemical signals in 
                         running waters, natural lakes and man-made impoundments. The 
                         possible future changes in climate and aquatic ecosystems in 
                         Brazil are highly uncertain. Inland waters are pressured by local 
                         environmental changes because of land uses, landscape 
                         fragmentation, damming and diversion of water bodies, 
                         urbanization, wastewater load, and level of pollutants can alter 
                         biogeochemical patterns in inland waters over a shorter term than 
                         can climate changes. In fact, many intense environmental changes 
                         may enhance the effects of changes in climate. Therefore, the 
                         maintenance of key elements within the landscape and avoiding 
                         extreme perturbation in the systems are urgent to maintain the 
                         sustainability of Brazilian inland waters, in order to prevent 
                         more catastrophic future events.",
