Biodiversity and biogeography—GBIF_Filter.

Definition part:

     Bacteria phyla (bacteria_main_groups)

   // all variables are set at zero (0) or an empty list

Define treatments and operations:

      Retrieve and set the classification used from the directory

   “Classification_2000_Plus”, see supplementary materials directory.

     Retrieve data from each geographical area fond in the directory

   “GBIF_Plus”, see  supplementary materials and filter and assign them to their

   respective phyla.

     Write the occurrences in the file “gbif_Classification_2000_Plus.txt”, see

   supplementary materials.

     Unclassified taxa are saved in the file.

    “absent_taxa_Classification_2000_Plus.txt” and

    “absent_taxa_Classification_2000_Plus_ex_All.txt” see supplementary

    materials.
