Timber and non-timber forest products in the northernmost Neotropical rainforest: Ecological factors unravel their landscape distribution.

摘要: Abstract The benefits provided by tropical rainforests are unevenly distributed throughout the landscape and shaped abiotic biotic components that influence spatial distribution functional traits of species involved. We tested whether environmental stratification rainforest in biophysical Landscape Units (LU), defined topography soil, is related to diversity, abundance productivity (standing biomass) tree assemblages provide potential forest products (PFP). Considering different PFP associated with specific plant traits, we also a phylogenetic signal exists among comprise use categories. Non-metric multidimensional scaling ordinations permutational analysis variance were based on frequency, 129 species, which classified as fodder, food, fuelwood, medicinal, melliferous, ornamental, plywood timber 15 plots 0.5 ha each. constructed studied analyzed strength (D-statistic) them. diversity useful changes LU.

However, since our study included broad variety structures, it possible dispersion change if consider uses within each category.
