Richness Patterns

Data of species and genus richness for the Northern Hemisphere for the present, masked for cold regions criteria and aggregated at two degree resolution with CRS “+proj=longlat +datum=WGS84 +no_defs +ellps=WGS84 +towgs84=0,0,0” The raster ‘cold-adapted_species.tif’ and ‘cold-adapted_genera.tif’ contains the richness of cold-adapted species and genera respectively, and is the data set used to produce Figure 3. The six files ‘cold-adapted_family_[family name].tif’ contain the richness for the Compositae, Poaceae, Leguminosae, Brassicaceae, Cyperaceae, and Rosaceae families. These are the six most common cold-adapted families for the Northern Hemisphere and is the data used to produce Figure 4. The script ‘read_plor_richness.patterns.R’ loads and plots one simple example of richness patterns in a Artic Polar Stereographic projection (EPSG:3995). The folder ‘ocean_layer’ contains an ocean layer shapefile used to facilitate data visualization.
