Longitude and latitude values, as well as values of four environmental variables (from the Bio-ORACLE dataset; Tyberghein et al., 2012) for each of 98 occurrence sites (locations where a species was recorded).
A data frame that specifies geographic locations and environmental conditions of 98 occurrence sites.
The species name is here set to 'bg', which stands for background
Mean calcite concentration (mol/m3)
