How important can the presence/absence of macrophytes be in determining phytoplankton strategies in two tropical shallow reservoirs with different trophic status?

This study aimed at comparing phytoplankton taxonomic classes and morpho-functional attributes in two shallow tropical reservoirs with different nutrient levels and representing extremes of the alternative stable states theory. The reservoirs, locally called Ninféias Pond (23°38′18.95″S; 46°37′16.3″W) and Garças Pond (23°38′40.6″S; 46°37′28.0″W), are located in the city of São...

New records of Nitella (Chlorophyta: Characeae) in Mato Grosso and Mato Grosso do Sul States, Brazil

Charophyceae (Chlorophyta) are a unique class of algae due their vegetative structure and macroscopic gametangia. The floristic survey of the genus Nitella (Characeae, Chlorophyta) in Mato Grosso (18º55'05"S and 54º50'39"W) and Mato Grosso do Sul States (19º12'03"S and 57º35'32"W), was performed by analyzing specimens from SP, HMS and CPAP herbarium specimens, and resulted in the...
