| ABSTRACT Ceratium furcoides has received attention due its invasive behavior in South America and consequent alterations in local phytoplankton communities. Pedalinhos Lake had been dominated by chlorophytes until 2015, when the first occurrence of this dinoflagellate was detected. In order to investigate the colonization process of this species, we monitored the meteorological variables and phytoplankton abundance of this urban lake on a weekly basis from September 2015 to September 2018. At the beginning of the invasion process (Year 1), a peak density of 10,170 ind.mL-1 was recorded, with a significant decrease to 23 ind.mL-1, indicating an initial, unstable process of adaptation, with notable oscillation and reduction of cyanobacterial blooms. At this... |
