Changes in taxonomic and functional diversity of plants in a chronosequence of Eucalyptus grandis plantations

Abstract Tree plantations have become one of the fastest-growing land uses and their impact on biodiversity was evaluated mainly at the taxonomic level. The aim of this study was to analyze environmental changes after the Eucalyptus plantation in an area originally covered by natural grasslands, tak...
