Seed Dispersal by Bats and Birds in Forest and Disturbed Habitats of Chiapas, Mexico1

摘要: We examined seed dispersal by bats and birds in four habitats of the Selva Lacandona tropical rain forest region, Chiapas, Mexico. The represented a disturbance gradient: active cornfield, ten-year-old abandoned cacao plantation, forest. Using traps before sunrise (0400 h) sunset (1800 h), we compared volant vertebrate dispersal, assuming that seeds found at end night were dispersed those day birds. did not find from other frugivores such as monkeys or opossums. In all more than most months also birds, except December when no traps. Bats consistently species although x2 comparison showed differences to be significant. Fifty percent pioneer species. Cecropia high percentage (up 87% up 83% birds) fell our influence on secondary successional processes is likely fundamental for establishment vegetation. Since (primarily disturbed areas consisting primarily species), they are play an important role restoration among structurally vegetationally different cornfields, old fields, plantations,
