Flow seasonality and fish assemblage in a tropical river, French Guiana, South America Neotropical Ichthyology
Tejerina-Garro,Francisco Leonardo; Mérona,Bernard de.
The objective of this study is to verify the existence of a seasonal pattern of variation in the fish assemblages of a tropical river using taxonomic and functional descriptors.

Four types of fish assemblage descriptors were used: the species descriptor (number of individual fish of each species in the sample); the family descriptor (number of individual fish of each family in the sample); the trophic descriptor (distribution of the fish biomass in each feeding guild) and the specific maximum observed size - MOS (number of...
