TL;DR: In this article, the authors studied phytoplankton diel variations in an Amazonian flood-plain lake (Lago Batata) for one year, according to the hydrometric level fluctuation of the Trombetas river (39.7-47.0 m over sea level), to which the lake is permanently connected.

TL;DR: Phytoplankton species may be more useful than these trophic indices to the classification of the condition of tropical lakes because there was no clear relationship between Secchi depth, chlorophyll, or TP and troPHic status.

TL;DR: The seasonal dynamics of S. roundii are studied, which can form blooms in the coastal Imboassica Lagoon, Rio de Janeiro stale, Brazil, and a tentative habitat template is offered, which appears to belong to D-assemblage, a set of small and fast-growing diatoms well represented in small, shallow and enriched waters.

TL;DR: The occurrence of Pseudo-nitzschia brasiliana Lundholm, Hasle & Fryxell, a recently described marine diatom, is reported for two distinct environments on the coast of the state of Rio de Janeiro, Brazil, during the El Nino-ENSO summer of 1998 as discussed by the authors.
