• Resumen

  • This study was conducted in burned and harvested areas of Catalonia. It was evaluated the effect of the granivorous in predispersive fruit removal of Smilax aspera and Quercus coccifera and postdispersive seed removal. Nuts removal by rodents was nil in the burned area while for S. aspera only occurred in 2008. The minimum distance to any unburned margin and the distance to the fire perimeter explained patterns of seed removal for rodents and ants, respectively. Seed removal was also lower at unlogged sites vs. logged ones but it was only significative for ants. Rodents removed more seeds under piles of branches because logging while ants did so in areas of bare soil. It should consider the impact of granivorous in the management of burned habitats.
