Life-history strategies drive plant species richness patterns in the Atlantic Forest hotspot

Aim: The underlying processes driving the origin and spatial variation of species richness stand as one of the most fundamental and enigmatic questions in ecology. Here, we assess the roles of water availability, energy availability, climatic seasonality, physiological tolerance, historical climate stability, topographic heterogeneity, and the mid-domain effect in shaping spatial richness variation among various plants of the Atlantic Forest.
Location: Atlantic Forest Hotspot, South America.
Taxon: 14,037 species of vascular plants (angiosperms and gymnosperms), including trees, lianas, shrubs, subshrubs, terrestrial herbs and epiphytic herbs.
Methods: We employed stacked ecological niche modeling to estimate species richness across different plant life forms. We then applied spatial models and hierarchical partitioning to assess the role and significance of each hypothesis in explaining species diversity variation.
Results: Spatial richness variation in the Atlantic Forest results from..., , , # Data from: Life-history strategies drive plant species richness patterns in the Atlantic Forest hotspot

## Description of the data and file structure

The data contains all the information and reproducible R scripts to generate the results and figures associated with the paper. Species distributions were estimated using ecological niche modeling. Presence-absence matrices were generated by stacking individual species models. Richness maps and statistical analyses were then conducted to evaluate the drivers of plant species richness across the Atlantic Forest.

All analyses were conducted using R (version ≥ 4.2).
