Rodent suppression of seedling establishment in tropical pasture.

Grasses are recognized as a critical regeneration barrier in tropical pastures, yet the effects of rodents and rodent-grass interactions are not well understood. As selective foragers, rodents could shape tree communities, moderating biodiversity in regenerating tropical landscapes. We utilized a fully crossed two-way factorial design to examine the effect that grasses, rodents, and their interaction had on tree seedling establishment in pasture habitat.
