Availability and species diversity of forest products in a Neotropical rainforest landscape

摘要: Abstract Tropical rainforests harbor a high diversity of tree species, offering potentially rich array timber (TFP) and non-timber (NTFP) forest products. The supply such products has been commonly evaluated at the local (plot) scale; however, little is known about how their availability change landscape scale, particularly in heterogeneous environments. This information critical designing management programs. Here, we assess extent to which frequency, abundance, diversity, composition productivity (aboveground biomass) assemblages with potential (PFPs) across three units (LUs) that differ soil topographic conditions. study was carried out well-conserved old-growth tropical rainforest southeastern Mexico. Three plots (0.5 ha each) were established per LU, all trees ≥ 10 cm inventoried, taxonomically identified assigned eight product categories. General linear models, multiple regression ordination analysis (CCA) used structural compositional changes supplying different PFPs among LUs along physicochemical gradients. More than half (94 57%) total number species (165) had one or more PFPs, mostly related Ordination showed abundance distribution LUs, nitrogen, pH aluminum saturation. Variation terms biomass strongly driven by available phosphorus physiological depth. Each LU provide products, producing diverse mosaic within landscape. Decisions concerning sustainable should consider variability landscapes, as well environmental factors govern this spatial variation.
