  • This article examines seed germination, predation, removal and death for six different species in undistured forest, logged forest and an active pature.
  • Because gaps created from logging are often overrun by liana tangles, it also compares between seeds planted under patches of lianas (low forest) and under patches of mature forest (high forest). Vieira and Scariot tested seeds from six different tree species that would all be at peak disperal at the same time but that represent a spectrum of seed size and dispersal mechanisms. 
  • They hypothesized that seed predation would be higher in logged sites, that seed predation would be more frequent on small seeds than large seeds in pasture, and that seed germination would be negatively impacted by shading beneath lianas in low forest and the extreme abiotic conditions in pastureland.
  • After monitoring for 8 months they founds that small seeded species had higher germination than larger seeds but were more susepticble to predation in pastureland. Large seeded species had highest seed removal in pastureland and high forest but had much lower removal rates in low forest. This suggests that lianas, while often thought to inhibit succeession, may protect large seeds from predation.
  • Vieira and Scariot recommend waiting until the end of the rainy season to cut back lianas so that seeds below are protected and have a greater chance of germinating.
