Description

  • The variety of ways that seeds disperse into a disturbed site affects the diversity of species that regenerate.
  • This article looks at the role of bat and bird dispersal in the regeneration of a disturbed forest on the Luzon Island of the Philippines.
  • Seed traps (1 x 1 m) were constructed and seven seed traps were placed at each point along a gradient of proximity to forest: along the forest edge and at 20, 40, 60, and 80 meters from the forest edge.
  • The traps captured an abundance of wind-dispersed seeds, which is characteristic of early-successional species.
  • However, unlike the typical paradigm, the even more animal-dispersed seed species were found on the site.
  • Bird dispersal was greater than bat dispersal in terms of seed abundance and species diversity. This predominance by birds was even higher in the dry season.
  • Dispersal was greater in areas with more fleshy-fruited trees, which attract the brids and bats, in closer proximity to the sample point.
