Resumo
Tigres Lake is a blocked valley lake, with no registered studies of
phytoplankton vertical distribution for that lake type; as such, our work assumes a
pioneering nature. The aim of this study was to recognize temporally and spatially the
vertical patterns of phytoplankton community attributes, to detect the dominant and
descriptive phytoplankton functional groups, and relate them to limnological characteristics.
Tigres Lake was characterized as a warm polymictic lake, featuring occasional thermal
stratification in deeper stations. The dry and early rainy seasons presented limnological
(evidenced by PCA) and biological (observed by CCA) differences. The dry months
presented more nutrient concentrations and greater transparency level; on those months,
phytoplankton functional groups Lo, Y, N and W1 were predominant; while the rainy
months featured higher temperatures and lower transparency levels, and the predominant
phytoplankton functional groups were S1, T and N. By jointly evaluating limnological
characteristics, biovolume and phytoplankton functional groups, it can be concluded that
the vertical profile of Tigres lake is oligo-mesotrophic.
