Phytoplankton functional groups in a subtropical Brazilian reservoir: responses to impoundment

Abstract: The discontinuity in rivers caused by the construction of reservoirs disrupts the longitudinal gradient and decreases the natural connectivity of lotic systems. We evaluated the dynamics of Reynolds functional groups (RFGs) in response to the formation of a subtropical reservoir, in relation to the environmental changes between the pre-and post-impoundment periods. We hypothesized that the disruption of longitudinal connectivity and the changes in the light and mixing regime after the impoundment would directl… Show more

“…The functional groups theory can be highlighted with two ideas: (1) a species belonging to a functionally well-adapted group can tolerate the limiting environment of factor deficiency more successfully than a less adapted species; (2) a light, P, or C or N constrained habitat is more likely to be populated by species with the appropriate adaptation properties [20]. Although phytoplankton functional groups have been described for lakes, this approach has also been applied to certain types of reservoirs in various regions [12,16,[22][23][24]. This has proved to be a useful method of evaluating ecological status in reservoir ecosystems.…”

“…Many studies have used phytoplankton functional groups in analyses of different systems around the world, such as reservoirs (e.g., Rangel et al, 2016;de Souza et al, 2016), rivers (e.g., Abonyi et al, 2012;Devercelli and O'Farrell, 2013), and floodplain lakes (e.g., Stanković et al, 2012a,b;Stević et al, 2013). Floodplain systems consist of flooded areas along the main river that periodically oscillate between the aquatic-terrestrial transition zone (ATTZ).…”

“…In its current form, the PFG approach uses more than 40 categories according to the sensitivities and tolerances of representative taxa, identified by alphanumeric codes (Padisa´k et al, 2009;Salmaso et al, 2014). In the past decade, the PFG approach has provided important information for understanding the dynamics of phytoplankton communities and has been successfully applied in temperate (Huszar et al, 2003;Leita˜o et al, 2003;Tian et al, 2015), subtropical (Becker et al, 2009;Souza et al, 2016;Xiao et al, 2011), and tropical (Costa et al, 2009;Gebrehiwot et al, 2017;Rodrigues et al, 2017) regions.…”
