Usage
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. -
