  abstract = {{M}any trophic indices have been constructed for temperate aquatic environments, but few have proved reliable for tropical environments. {I}ndices constructed on the basis of nutrients may not be effective for describing the trophic state because the fractions of nitrogen and phosphorus differ in their potential to predict the nutrient limitation in tropical aquatic environments. {W}e developed an index based on the phytoplankton {R}eynolds functional groups for an {A}mazonian floodplain lake from samples collected during 2 contrasting hydrological periods (rising and flushing) and compared it with the index initially proposed by {C}arlson in 1977 and further adapted to tropical environments by {T}oledo in 1990. {T}he functional group and {C}arlson indices matched only 37% and 56% of the sample units collected during the rising and flushing periods, respectively. {O}ur study confirms the difficulty of assessing trophic states using only phosphorus and chlorophyll a in tropical floodplain lakes. {I}n this environment (1) nitrogen may significantly limit phytoplankton growth and (2) complex phytoplankton-nutrient relationships occur during the hydrological cycle that cannot be accounted for through a simple phosphorus and chlorophyll a formula.},
