Diversidade de espécies, diversidade funcional e estoque de biomassa no sub-bosque de florestas nativas e monoculturas arbóreas

Abstract

The conversion of native forests to tree monocultures have been producing an heterogeneus landscape mosaic where the capacity of colonization of understorey plants from adjacent forest is still unknown. These changes in land use may lead to modifications on plant species composition which can alter forest carbon storage. These study investigates differences in species composition, species richness, abundance and functional richness of plants that colonized the understorey of forests and tree monocultures. It also investigates how species diversity and the diversity of functional groups could influence biomass storage in the understorey. The study was conducted at the São Francisco de Paula National Forest, RS, Brazil, using three replicates of each of the following habitas monocultures of Pinus, Eucalyptus and Araucaria angustifolia and Araucaria forest. In each of the 1 study sites five 8m² plots and five 1m³ plots were defined. Richness, abundance and biomass storage of plant species were surveyed and sepa
