- Abstract
the reproductive success of plants depends on the dispersal of their seeds. One of the processes influencing this dispersal is predation. In particular, post-dispersal predation influences the survival and spatial distribution of plants. In this work we evaluated the relationship of post-dispersal predation of seeds of three palms, Oenocarpus bataua, Euterpe precatoria and Socratea exorrhiza, with the patterns of dense-dependence, seed size and germination, in a forest of eastern Colombia. Three individuals were selected from each palm species, from which seeds were collected according to their aggregation pattern, forty aggregated seeds and forty non-aggregated seeds. Seed weight, diameter, germination, and predation were determined. It was found that seed size was different in the three palm species, there was a positive correlation between seed weight and diameter, predation percentages were approximately 50 %, and there was a relationship between seed germination and predation. Thus, the population dynamics of the palms under study can be associated with seed characteristics such as size, germination, density-dependence and their ability to resist predators.
