Pasture damage by an Amazonian earthworm
Article Abstract:
Research into pasture degradation in central Amazonia, near Manaus, Brazil, indicates that soil macrofauna can have a significant and long-term impact on the porosity of pasture soils. If tropical rainforest remains undisturbed, an extremely diverse soil macrofauna maintains an adequate soil pore volume by balance the impact of compacting and decompacting agents. Biodiversity declines significantly following deforestation and the establishment of exotic grasses, with large populations of the earthworm P. corethrurus emerging. These earthworm populations dramatically reduce macroporosity.
