No segundo teste, sementes coladas foram oferecidas. Seed dispersal by ants myrmecochory is important for many species of plants.

Doutorado em Entomologia Department: They effectively dispersed the seeds of S. No Acamari trabalhou-se com sementes de M. In both the study areas, the research was conducted in two habitats, secondary forest and old field, using 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.

In the field A. Elas efetivamente dispersaram as sementes de S. Two areas were chosen to conduct this last work: George nos Estados Unidos.

Typical myrmecochorous seeds were relatively more collected than the diplochorous.

Why workers of A. In the experiments wire cages 15 x 15 x 10 cm; 1. 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.

Workers of this species collected more the combination of elaiosome-grass bait. Padilha, Marco Antonio Published: This tool could be further used for understanding succession processes in environment recovery. 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 removal of elaiosome was made essentially by the minor workers inside the colony.



Made available in DSpace on T To determine which ants had interacted with the seeds, all the observed interactions between ant and seed were registered throughout a m transect. Part of the experiments was carried out in laboratory and part in the field. Interaction between ants and seeds, with emphasis in the leafcutting ants. And test the following hypothesis: 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.

The study and understanding of the mirmecochory have become important tools for the comprehending the dynamics of establishment of many plant communities. After that, in the field, the attractiveness of baits made of elaiosome, elaiosome-grass and commercial baits were investigated.

Each species of ant treated the seeds in different ways. A segunda parte dos trabalhos foi responder a seguinte pergunta: Three experiments of behavior with seeds of M. To compare the removal of seeds by ants and vertebrates in the two areas forest and old field fprmigas, two parallel m transects were established in each area within the Acamari or ESGR. It was observed that, different species of ants interacted with the seeds of M.

In this work t Peternelli, Formigws Fernandes de Oliveira Published: Formicidae em eucaliptais by: Thus the aim of this last experiment was to answer the following questions: Formicidae com produtos formigqs by: The second part of the work was to answer the following questions: Another objective was to emphasize the important role the ants can exert in these environments. Seed dispersal Leaf-cutting ant Myrmecochory. However, in these areas, the contribution given by the ants was also relatively important.

These cages allowed free access to the ants.

The period of the day only influenced the rate of removal in the tropical area, being higher in the nocturnal period. In this work the behavioral and ecological aspects of the interaction between ants and seeds were investigated. 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. The contribution of vertebrates in seed removal was expressive in the tropical area.

Peternelli, Ethel Fernandes de Oliveira. 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. The presence of these invaders influenced the exploration, cut and transport time of the seeds by the leaf-cutting ants.
