Data and code for "Leaf dry matter content is phylogenetically conserved and related to environmental conditions, especially wildfire activity"Files in the folder:1 - LDMCdataset.csvIt contains:species: species names checked according to the World Flora Online (https://www.worldfloraonline.org/)phylogenetic_groups: classify according to APG III (2009)(http://www.mobot.org/MOBOT/research/APweb/).growth_form: classify according to the descriptions of each species’ adult form in the Encyclopedia of Life (https://eol.org/)postfire_regeneration: species that have or do not have traits associated with postfire regenerationregeneration_strategies: seeders (facultative seeders and obligate seeders), non-seeders (obligate resprouters), and unknown (species were only reported to have seedling emergence in the first year after fire, but it is unclear how they specifically regenerated)LDMC: leaf dry matter content (original unit: g g-1)FA: defined as the logarithm of the average number of fire incidences in each region divided by the size of the region, as recorded by the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor in the Terra satellite at 30 seconds resolution, no unitTN: soil total nitrogen content (original unit: g kg-1)MAT: mean annual temperature (original unit: ℃)MAP: mean annual precipitation (original unit: mm)AI: aridity index (the ratio of mean annual precipitation to mean annual reference evapotranspiration)2 - LDMC.treeThe phylogenetic tree for the species list in LDMCdataset.csv.3 - Main_Analysis_Code.RIt contains all the analytical steps to reproduce the results reported in the main text.4 - Check_Species_Names.RCode for verifying and correcting species names. Species names are matched against the World Flora Online Taxonomic Backbone using the WorldFlora package.5 - GBIF_Coordinate_Cleaning_and_Environmental_Data_Extraction.RCode for extracting species distribution data from GBIF, cleaning erroneous coordinates, and linking these coordinates to environmental variables such as fire activity, soil total nitrogen content, mean annual temperature, mean annual precipitation, and aridity index.6 - Figure_Replication_Steps.txtProvides detailed instructions on replicating Figures 1–4 using Origin software.7 - WFOTaxonomicBackbone_v.1.7_20220712.zipThe World Flora Online Taxonomic Backbone database used for species name verification (Source:https://www.worldfloraonline.org/downloadData).8 - unchecked_species_name.csvA list of species names prior to review and correction.9 - wc2.1_30s_bio_1.tifRaster file containing global data for mean annual temperature (MAT) at 30 seconds resolution from the WorldClim (https://www.worldclim.org/data/worldclim21.html).10 - wc2.1_30s_bio_12.tifRaster file containing global data for mean annual precipitation (MAP) at 30 seconds resolution from the WorldClim (https://www.worldclim.org/data/worldclim21.html).11 - fire activity.tifRaster file with fire activity index data prepared for spatial analysis in the study (source: https://doi.org/10.6084/m9.figshare.4579327.v2).12 - nitrogen.tifRaster file for soil total nitrogen content sourced from SoilGrids (https://geodata.ucdavis.edu/geodata/soil/soilgrids/).13 - ai_v3_yr.tifRaster file for aridity index sourced from the Global Aridity Index database (https://doi.org/10.6084/m9.figshare.7504448.v6).
