Ants respond to the external stimulations promoted by an appendage elaiosome rich in lipids, attached on to the seed, by carrying the seeds to their nests, where the appendage is removed and used as food. A segunda parte dos trabalhos foi responder a seguinte pergunta: Padilha, Marco Antonio Published: No segundo teste, sementes coladas foram oferecidas.

The presence of these invaders influenced the exploration, cut and transport time of the seeds by the leaf-cutting ants. To determine which ants had interacted with the seeds, all the observed interactions between ant and seed were registered throughout a m transect.

However, in these areas, the contribution given by the ants was also relatively important. The study and understanding of the mirmecochory have become important tools for the comprehending the dynamics of establishment of many plant communities. In the field A. The contribution of vertebrates in seed removal was expressive in the tropical area.

Initially the role of volatile produced by elaiosome of seeds of Mabea fisutlifera Euphorbiaceae in the attraction of ants Atta sexdens rubropilosa and Atta bisphaerica was investigated, with the use of olfactometry in laboratory.

In olfactometer, the ants were attracted by volatile of the seeds with elaiosome and by odor of commercial baits when air was offered as alternative source. In the experiments wire cages 15 x 15 x 10 cm; 1.

They effectively dispersed the seeds of S. And test the following hypothesis: Seed dispersal by ants myrmecochory is important for many species of plants. Thus the aim of this last experiment was to answer the following questions: Peternelli, Ethel Fernandes de Oliveira Published: This tool could be further used for understanding succession processes in environment recovery.

Why workers of A. Formicidae com produtos naturais by: Part of the experiments was carried out in laboratory and part in the field.

The second part of the work was to answer the following questions: To compare the removal of seeds by ants and vertebrates in the two areas forest and old fieldtwo parallel m transects were established in each area within the Acamari or ESGR. George nos Estados Unidos.

No Acamari trabalhou-se com sementes de M. Workers of this species collected more the combination of elaiosome-grass bait. The removal of elaiosome was made essentially by the minor workers inside the colony.

Made available in DSpace on T In the second test, glued seeds were offered; in the third test, the seeds were allowed to be explored by the workers of leaf-cutting ants with the presence of two invading species, Pheidole sp. Interaction between ants and seeds, with emphasis in the leafcutting ants. It was concluded that volatiles of seed elaiosomes were attractive to the ants, and also that composites of elaiosome have potential to be used in the confection of toxic baits.

In the third and last part removal rates of seeds in two succession stage; old field with shrub regeneration and secondary forest, in tropical and temperate environments were evaluated. Another objective was to emphasize the important role the ants can exert in fromigas environments.

In this work the behavioral and ecological aspects of the interaction between ants and seeds were investigated. Peternelli, Ethel Fernandes de Oliveira.

Three experiments of behavior with seeds of M.
