In both the study areas, the research was conducted in two habitats, secondary forest and old field, using seeds of M. Workers of this species collected more the combination of elaiosome-grass bait. Typical myrmecochorous seeds were relatively more collected than the diplochorous.

No segundo teste, sementes coladas foram oferecidas. 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. These cages allowed free access to the ants.

This tool could be further used for understanding succession processes in environment recovery. Formicidae em eucaliptais by: The removal of elaiosome was made essentially by the minor workers inside the colony. Another objective was to emphasize the important role the ants can exert in these environments. Part of the experiments was carried out in laboratory and part in the field. A segunda parte dos trabalhos foi responder a seguinte pergunta: Padilha, Marco Antonio Published: It was concluded that volatiles of seed elaiosomes were attractive to the ants, and also that composites of elaiosome formiyas potential to be used in the confection of toxic baits.

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 fotmigas in laboratory. Thus the aim of this last experiment was to answer the following questions: After that, in the field, the attractiveness of baits made of elaiosome, elaiosome-grass and commercial baits were investigated.

Cortadeirax Acamari trabalhou-se com sementes de M. Formicidae com produtos naturais by: Peternelli, Ethel Fernandes de Oliveira Published: The contribution of vertebrates in seed removal was expressive in the tropical area. The second part of the work was to answer the following questions: The presence of these invaders influenced the exploration, cut and transport time of the seeds by the leaf-cutting ants. And test the following hypothesis: To determine which ants had interacted with the seeds, all the observed interactions between ant and seed were registered throughout a m transect.

In the experiments wire cages 15 x 15 x 10 cm; 1. Each species of ant treated the seeds in different ways. Doutorado em Entomologia Department: 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. 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.

In this work t However, in these areas, the contribution given by the ants was also relatively important. Made available in DSpace on T Seed dispersal by ants myrmecochory is important for many species of plants.

They effectively dispersed the seeds of S. The study and understanding of the mirmecochory have become important tools for the comprehending the dynamics of establishment of many plant communities. Why workers of A. Three experiments of behavior with seeds of M. Elas efetivamente dispersaram as sementes de S.

Interaction between ants and seeds, with emphasis in the leafcutting ants. It was observed that, different species of ants interacted with the seeds of M.

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. Two areas were chosen to conduct this last work: In the field A. The period of the day tormigas influenced the rate of removal in the tropical area, being higher in the nocturnal period.

Seed dispersal Leaf-cutting ant Myrmecochory. In this work the behavioral and ecological aspects of the interaction between ants and seeds were investigated. Peternelli, Ethel Fernandes de Oliveira. In olfactometer, the ants were attracted by volatile of the seeds with elaiosome and by odor of commercial baits cortadeirs air was offered as alternative source.
