This book was released on 1982 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Above-qcound net primary productivity (NPP) , herbivory and vegetation structural characteristics were measured in high and low diversity successional and agricultural ecosystems at a wet tropical site near Turrialfca, Costa Bica. Insecticide and defoliation experiments were performed to evaluate the effects of herbivory on NPP in high and low diversity ecosystems. The four experimental ecosystems were enriched succession (natural regeneration augmented by propagule additions) , natural succession (control) , successional mimic (an ecosystem with investigator-controlled species composition designed to imitate natural succession), and successional monoculture (two naize crops followed by cassava) . Plant species richness and leaf area index (LAI) were highest in the enriched, high in the natural succession, intermediate in the miiiiic, and low in the monoculture at 1.5 yr.
