We examined how vegetation mosaic influences distribution of the edaphic ant (Formicidae) community in the northern part of the Pantanal in Cáceres, State of Mato Grosso, Brazil. Plant formations (hereafter habitats) that characterize this area include several savanna types, such as: Cerrado sensu stricto, Cerradão, Semi-deciduous forest, Termite savanna, Open fields and Cerrado field/carandazal. Pitfall traps were placed in ten 250 m transects each one separated by 1 km, within an area of 2 x 5 km (following RAPELD methodology). Five traps at intervals of 50 m were placed along each transect, in September and December 2008. Forty-four ant species were collected. leaf litter predicted ant presence and influenced species occurrence in the different habitats. Pantanal habitats are very different structurally from one to another, which has have resulted in areas with very specific ant assemblages. The understanding of the antcommunity structure in these areas is fundamental to floodplain management.
