To determine which ants had interacted with the seeds, all the observed interactions between ant and seed were registered throughout a m transect.

The presence of these invaders influenced the exploration, cut and transport time of the seeds by the leaf-cutting ants. Formicidae com produtos naturais by: Elas efetivamente dispersaram as sementes de S.

In both the study areas, the research was conducted in two habitats, secondary forest and old field, using seeds of M. It was observed that, different species of ants interacted with the seeds of M.

Another objective was to emphasize the important role the ants can exert in these environments.

The second part of the work was to answer the following questions: Formicidae em eucaliptais by: Two areas were chosen to conduct this last work: This tool could be further used for understanding succession processes in environment recovery. After that, in the field, the attractiveness of baits made of elaiosome, elaiosome-grass and commercial baits were investigated.

Peternelli, Ethel Fernandes de Oliveira. No Acamari trabalhou-se com sementes de M. Workers of this species collected more the combination of elaiosome-grass bait.

However, in these areas, the contribution given by the ants was also relatively important. 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. Three experiments of behavior with seeds of M. In the third cortaderas 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.

Why workers of A. Padilha, Marco Antonio Published: Seed dispersal by ants myrmecochory is important for many species of plants. Typical myrmecochorous seeds were relatively more collected than the diplochorous.

The contribution of vertebrates in seed removal was expressive in the tropical area. Doutorado em Entomologia Department: The removal of elaiosome was made essentially by the minor workers inside the colony. Seed dispersal Leaf-cutting ant Myrmecochory.

In the second test, glued seeds were offered; in cortadwiras 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.

George nos Estados Unidos. In the field A. Made available in DSpace on T 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. These cages allowed free access to the ants. They effectively dispersed the seeds of S.

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. Each species of ant treated the seeds in different ways. No segundo teste, sementes coladas foram oferecidas. The study and understanding of the mirmecochory have become important tools for the comprehending the dynamics of establishment of many plant communities.

Peternelli, Ethel Fernandes de Oliveira Published: Thus the aim of this last experiment was to answer the following questions: 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.

The period of the day only influenced the rate of removal in the tropical area, being higher in the nocturnal period.

Part of formigad experiments was carried out in laboratory and part in the field. 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. Interaction between ants and seeds, with emphasis in the leafcutting ants. In this work t A segunda parte dos cortaveiras foi responder a seguinte pergunta: In the experiments wire cages 15 x 15 x 10 cm; 1.

And test the following hypothesis: In this work the behavioral and ecological aspects of the interaction between ants and seeds were investigated.
