Why workers of A.

Formigas cortadeiras, queimada sazonal e a distribuição de n by Lukas Brayan on Prezi

In the experiments wire cages 15 x 15 x 10 cm; 1. George nos Estados Unidos. The second part of the work was to answer the following questions: Each species of ant cortadeirras the seeds in different ways.

Elas efetivamente dispersaram as sementes de S. To determine which ants had interacted with the seeds, all the observed interactions between ant and seed were registered throughout a m transect.

Three experiments of behavior with seeds of M. Seed dispersal Leaf-cutting ant Myrmecochory. 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.

And test the following hypothesis: Cortadeirae the aim of this last experiment was to answer the following questions: Peternelli, Ethel Fernandes de Oliveira.

After that, in the field, the attractiveness of baits made of elaiosome, elaiosome-grass and commercial baits were investigated. Workers of this species collected more the combination of elaiosome-grass bait.


Part of the experiments was carried out in laboratory and part in the field. Typical myrmecochorous seeds were relatively more collected cortadeias the diplochorous. Interaction between ants and seeds, with emphasis in the leafcutting ants. Padilha, Marco Antonio Published: 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.


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

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.

Seed dispersal by ants myrmecochory is important for many species of plants. A segunda parte dos trabalhos foi responder a seguinte pergunta: Fromigas, in these areas, the contribution given by the ants was also relatively important.

Formicidae com produtos naturais by: 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 both the study areas, the research was conducted in two habitats, secondary forest and old field, using seeds of M.

The removal of elaiosome was made essentially by the minor workers inside the colony. In the field A. 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 study and understanding of the mirmecochory have become important tools for the comprehending the dynamics of establishment of many plant communities.

Cortaeeiras available in DSpace on T This tool could be further used for understanding succession processes in environment recovery. Two areas were chosen to conduct this last work: The period of the day only influenced the rate of removal in the tropical area, being higher in the nocturnal period. Formicidae em eucaliptais by: In this work 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.

These cages allowed free access to the ants.

Peternelli, Ethel Fernandes de Oliveira Published: The presence of these invaders cortdaeiras the exploration, cut and transport time of the seeds by the leaf-cutting ants. No Acamari trabalhou-se com sementes de M. In this work the behavioral and ecological aspects of the interaction between ants and seeds were investigated. The contribution of vertebrates in seed removal was expressive in the tropical area.

No segundo teste, sementes coladas foram oferecidas.
