abstract = "The Amazon floodplains are complex systems influenced by the
annual hydrological regime with an effect on the structuring of
physical, chemical and biological processes. Thus, we evaluated
the relationship of environmental factors with the composition and
variation of functional groups based on morphology (MBFG) during
the hydrological year in an Amazonian floodplain lake, with
monthly sampling (2013 to 2014). We used analysis of variance
(ANOVA) and KruskalWallis to show differences in physicochemical
variables between hydroperiods. We performed permutation analysis
of variance (PERMANOVA) to assess the dissimilarity of
morphofunctional groups between hydroperiods and also of
environmental data between the months of the study and RDA
redundancy analysis to assess the relationship between MBFGs and
environmental data. It was registered 101 taxa distributed in
eight taxonomic categories and was grouped into 5 MBFGs (III, IV,
V, VI and VII), with Chlorophyceae (31 taxa) and Cyanobacteria (27
taxas) with the higher number of taxa. Furthermore, there was a
dominance of Cyanobacteria in the total biovolume, which form
blooms (MBFGs III and VII) during the periods of falling and low
water in lake, influenced mainly by the reduction in the
availability of light and an increase in temperature. In another
scenario, the dominance of MBFGs V and VI occurred during periods
of rising and high water with association with carbon compounds,
rainfall, SRP and NO2. Thus, our results demonstrate that the
availability of light, the concentration of nutrients and
temperature were the most important variables for the
morphofunctional structuring of phytoplankton in aquatic system.",
