Resumo: | The main selective forces affecting the fruiting strategies are related to the environment in which plants occur. As a savanna, microclimatic conditions should not vary in relation to distance from edge in cerrado sensu stricto fragments. Thus, we postulated that the importance of different dispersal syndromes would not vary towards the fragment core. Our aim was to test in four cerrado sensu stricto fragments in central Brazil whether the absolute density of anemo-, auto-, and zoochorous individuals varied in relation to edge distance. According to results, the absolute density of anemo-and autochorous individuals did not vary, whereas those of zoochorous individuals increased with edge distance, pointing out that there were other factors rather than abiotic conditions shifting zoochorous species to the interior of cerrado sensu stricto fragments.
