However, Chellappa and Costa (2003) found that the introduction of intensive fish farming in the Gargalheiras reservoir in the state of Rio Grande do Norte (Northeastern Brazil), previously dominated by cyanobacteria, provided favorable conditions for the dominance of species of Chlorophyceae, especially Chlorococcales
The green alga species Pseudokirchneriella subcapitata, belonging to the order Chlorococcales
, class Chlorophyceae, was acquired in the Laboratory of Phycology of University of Concepcion, Chile.
The increase in species richness observed during the first days of colonization in the artificial substratum, was possibly due to the propagules present in the environment, since the habitat was not yet colonized, the migration processes favor the colonization and succession of species, allowing the composition of not only colonizing and opportunistic species of diatoms, as well as Chlorococcales
, Desmidiales and filamentous algae, as Bulbochaete and Oedogonium.
The phytoplankton, volvocles, chlorococcales
was found to be the most prevailing throughout the study period and exhibited their extreme adaptability to varied ecological conditions.
