Successional Pathways...
A team of investigators, post-doctoral investigators, graduate, and undergraduate students are synthesizing results from four initially independent projects on secondary forest regeneration in central Amazonia, Brazil, Costa Rica, and Chiapas, Mexico. These studies provide a wide array of successional sites, encompassing a range of successional stages, climatic gradients, and land-use histories in tropical forest ecosystems
