Code and metadata for "From canopy to understory: Unravelling multi-strata drivers of tree beta diversity in Amazonian forests"

This repository contains two R scripts and associated plot-level metadata used in the study "From canopy to understory: Unravelling multi-strata drivers of tree beta diversity in Amazonian forests". The scripts reproduce key analyses performed in the study: Mantel and partial Mantel tests between floristic, environmental and geographic distance matrices, including variable selection procedures. Variance partitioning using climatic, edaphic and geographic variables. PERMANOVA analyses to identify significant environmental predictors, followed by NMDS ordinations with environmental fitting (envfit) based on the selected variables. The metadata file includes geolocation, elevation, and forest type for each plot. Floristic data are available on request via ForestPlots. This Zenodo record is currently private and will be made public upon article acceptance.
