Pre‐adaptation and adaptation shape trait‐environment matching in the Neotropics

The resources provided here comprise raw and final data sets used in our study 'Preadaptation and adaptation shape trait-environment matching in the Neotropics' (DOI: 10.1111/geb.13730) comprising curated geographic occurrences for 156 Swartzia taxa across its distribution in the Neotropics, phylogenetic information for 69 Swartzia taxa, and corresponding climatic (i.e. 19 climatic variables taken from WorldClim), soil (i.e. sand, nitrogen, and clay content taken from the SoilGrids 2.0 portal), and trait data for each taxa (i.e. trait measurements for lefleats, petals, and fruits). We also provide the script used to extract trait information from botanical monographs.

Methods
The data-sets were collected using various methods. Trait data include measurements taken from the literature for leaflets, fruits, and petals, mainly from the works of Cowan (1967), and Torke and Mansano (2011) (but see detailed references provided in the corresponding supplementary files). Additional data for leaflets and fruits were obtained from herbarium specimens as described in the paper (see also the herbarium references provided in the corresponding supplementary files ). Data for nuclear and plastid DNA sequences were obtained from the study of Torke and Schall (2008). Phylogenetic trees were generated using BEAST2 (Bouckaert et al. 2014) , as described in the paper (see Methods). Data on occurrences were obtained from herbarium sources and curated posteriorly. For the occurrence dataset, we extracted climate data from WorldClim 2 (Fick & Hijmans 2017) and soil data from SoilGrids 2.0 (Poggio et al. 2021). See detailed information for each supplementary file provided in the README file.
