abstract = "Evolutionary computation has been applied to predict
the occurrence of massive cyanobacteria proliferations;
in the present study, this tool was further used to
explore the factors responsible for maintaining
picocyanobacterial dominance. Aiming to increase the
understanding of factors that promote dominance of
picocyanobacteria in tropical reservoirs, we chose two
reservoirs used for water supplies located in different
regions of Brazil and subjected to climate changes such
as warmer winters that intensify water column
stratification and prolonged dry seasons that cause
water level decreases. This study focused on the
diagnosis of the relationships among picocyanobacteria
(1-2 micrometer), zooplankton and environmental
variables using evolutionary computation. The
integrated data analysis performed here was very
successful in elucidating the dynamics of
picocyanobacterial density variation influenced by both
abiotic and biotic factors by the modeling approach.
Relative water column stability - RWCS and electrical
conductivity were highlighted as the most important
environmental drivers for picocyanobacterial peaks.
Hybrid Evolutionary Analysis (HEA) models for the two
reservoirs indicated for the first time in the
literature that rotifers, small-sized cladocerans and
copepods (mainly nauplii) can directly or indirectly
control picocyanobacteria in tropical mesotrophic
reservoirs, depending on RWCS conditions and electrical
conductivity. However, this control is modulated by pH,
water transparency and water temperature thresholds.",
