A comparative dataset on population genetics, traits, and distributions for nineteen Caribbean tree species

We present a comparative genetic dataset of 19 tree species (including one palm) from the Caribbean island of Puerto Rico, as well as some samples from neighboring islands (Hispañola and the US Virgin Islands). Using a reduced-representation sequencing technique (SLAF-seq), we identified species-specific single-nucleotide polymorphism (SNP) datasets with 24,413 to 433,637 high-quality SNPs per species. The focal species represent a range of life-history and climate associations; we therefore include complementary information on species functional traits (wood density, leaf thickness, specific leaf area, maximum height, and seed dry mass), as well as geographic distributions and climatic associations from species distribution models. All raw reads from the SLAF-seq sequencing are available at the European Nucleotide Archive (ENA, https://www.ebi.ac.uk/ena/browser/home) under the project accession number PRJEB96042 In this repository, we share the output from the Species distribution models (SDMs.zip). The file names correspond to the Species codes in the Species trait data (Species_Traits.xlsx) We also share the R scripts to run the Species distribution models 1_Environmental_variables.R: processing of environmental data downloaded at http://prism.oregonstate.edu 2_SDMs.R : Running the species Distribution models (SDMs) 3_Read_RDA.R : demonstration script on how to read the.
