Summary
A 13-year monitoring of copepods in two habitats of a flooding savanna (flooded grassland and open water ponds) during dry and rainy seasons, revealed the existence of 15 species, 2 calanoids and 13 cyclopoids. 7 species appeared with high frequency during all the time of study. The flooded grassland shown highest species richness (15) and frequency of appearance than ponds. Cluster analysis defined 8 groups, 2 corresponding to the open water ponds and 6 to the flooded grassland. Only 4 species, Notodiaptomus henseni, Mesocyclops meridianus, Microcyclops varicans, and Thermocyclops decipiens, were found both in flooded grasslands and ponds, during dry and rainy seasons.
