Each species of ant treated the seeds in different ways. Formicidae com produtos naturais by: No segundo teste, sementes coladas foram oferecidas.

Padilha, Marco Cortadeirsa 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.

Typical myrmecochorous seeds were relatively more collected than the diplochorous.

George nos Estados Unidos. It was observed that, different species of ants interacted with the seeds of M. Peternelli, Ethel Fernandes de Oliveira Published: Thus the aim of this last experiment was to answer the following questions: And test the following hypothesis: 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.


Seed dispersal Leaf-cutting ant Myrmecochory.

These cages allowed free access to the ants. Peternelli, Ethel Fernandes de Oliveira. The period of the day only influenced the rate of removal in the tropical area, being higher in the nocturnal period.

Two areas were chosen to conduct this last work: Another objective was to emphasize the important role the ants can exert in these environments. 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 second part of the work was to answer the following questions: Workers of this species collected more the combination of elaiosome-grass bait.

The study and formiags of the mirmecochory have become important tools for the comprehending the dynamics of establishment of many plant communities.

In the experiments wire cages 15 x 15 x 10 cm; 1. In both the study areas, the research was conducted in two habitats, secondary forest and old field, using seeds of M.

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 Corttadeiras or ESGR. 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.


Interaction between ants and seeds, with emphasis in the leafcutting ants. In this work the behavioral and ecological aspects of the interaction between ants and seeds were investigated.

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.

In this work t No Acamari trabalhou-se com sementes de M. The removal vormigas elaiosome was made essentially by the minor workers inside the colony.

Made available in DSpace on T The contribution of vertebrates in seed removal was expressive in the tropical area. Seed dispersal by ants myrmecochory is important for many species of plants. Why workers of A. The presence of these invaders influenced the exploration, cut and transport cortaderias of the seeds by the leaf-cutting ants.
