data(plant_richness_df)Format
A data frame with 227 rows and 22 columns:
ecoregion_id: Id of the ecoregion).x: Longitude in degrees (WGS84).y: Latitude in degrees (WGS84).richness_species_vascular: Number of vascular species found in the ecoregion. Response variable.bias_area_km2: Area of the ecoregion in squared kilometers.bias_species_per_record: Number of species divided by the number of spatial GBIF records available in the ecoregion as a measure of sampling bias.climate_aridity_index_average: Average of the ecoregion.climate_hypervolume: Volume of the climatic envelope of the ecoregion, computed with the hypervolume package.climate_velocity_lgm_average: Average climate velocity of the ecoregion since the Last Glacial Maximum.neighbors_count: Number of immediate neighbors of the ecoregion as a measure of connectivity/isolation.neighbors_percent_shared_edge: Percentage of shared edge with the neighbors as a measure of connectivity/isolation.human_population_density: Population density of the ecoregion.topography_elevation_average: Average elevation of the ecoregion.landcover_herbs_percent_average: Average cover percentage of herbs extracted from MODIS Vegetation Continuous Fields.fragmentation_cohesion: Geographic fragmentation index of the ecoregion as computed with the R package landscapemetrics.fragmentation_division: Another fragmentation index.neighbors_area: Total area of the ecoregions's immediate neighbors.human_population: Human population in the ecoregion.human_footprint_average: Average human footprint in the ecoregion.climate_bio1_average: Average mean annual temperature.climate_bio15_minimum: Average precipitation seasonality.
