Plant-soil interactions to maintain biodiversity and functions of tropical forest ecosystems

Organizer: Kazumichi Fujii

Unique features of tropical forests are their high biodiversity and productivity on strongly-weathered soils, which contrast with temperate forests that support much lower diversity on more fertile soils. Patterns and processes of plants, soils, and their interactions are diverse among tropical forests. New data are recasting the existing image of tropical forest-soil systems and raise new question: to what extent do plants, soils, or their interactions determine variation in biodiversity and functions among tropical forest ecosystems? To answer this question, different viewpoints of plant ecology and soil ecology, and those from different research sites are needed. We invite tropical soil scientists and plant ecologists from tropical America, Africa, and Southeast Asia to discuss the needs and possibilities of a cross-continental comparison.
