Resumen
This study evaluated the effect of periodic flooding and habitat structure on
the richness and distribution of the soil ant assemblage in a comparative study of floodprone areas (grassland, mounds and landizais fields), non flooded areas (ridges and
cerrado) in the Northern region of the Pantanal, based on the following items: (i) what is
the richness of soil ants occurring in this region? (ii) what is the influence of periodic
flooding as to the richness and distribution of soil ant community, comparing flooded
and non flooded areas in region north the Pantanal? and (iii) what is the effect of
vegetation structure on the distribution and richness of soil ant assemblage in region
north the Pantanal? The results of this research indicate that the northern region of the
Pantanal has a wide richness of species of soil ants and can be compared to ant richness
in areas of the Cerrado, the Atlantic Forest. The registration of four new species of ants
for this region indicates that the richness found in this environment is probably higher,
highlighting the need to continue these studies. It was observed that the ants move from
the wetlands to non flooded areas during the aquatic phase of the Pantanal, where they
remain throughout the flood period, returning to their habitats of origin during the low
water period. This move causes the structuring of the assemblage in mosaics with
specific compositions in both the studied areas. The structural variation in the Pantanal
vegetation types (range, savannah, landizal, carvoal, mound field, and grassland)
influences directly the distribution of the ant assemblage. The percentage of sand and
the accumulation of litter were significant factors in the distribution of the soil ant
assemblage in this region, forming different groups among the studied areas. The flood
rates and structural change in the vegetation, characteristic of the Pantanal, provide a
wide range of habitats and resources which are necessary for soil ants over the seasonal
period to which the region is subject, generating assemblage with distinct patterns and
dynamics in each type of habitat in this flooded ecosystem.
