Hi Armand, If you take taxa broadly yes a lot as we need to merge many taxonomies into a single one. This is too much to describe here in detail, an overview is here: https://data-blog.gbif.org/post/gbif-backbone-taxonomy/ If it is on names only not so much. We try to prefer IPNI/ZooBank spellings. We show the authority year always with a comma and try to remove all nomenclatural or taxonomic annotations like "s.l." "comb.nov." from the authorship. If the primary source has no authorship or publication we try to augment that from secondary sources, which could also alter the meaning of the primary one. Named hybrids should receive a space after the hybrid marker. That is from the top of my head what is happening to names in the backbone, but likely I am have missed things. Markus On 24.

Sometimes with sometimes without spaces in between initials and surnames. When we build the backbone we try to normalize authorships to have a consistent format, thereby those blanks everywhere.

In the original data resource the blanks are present. Gbif remove some where the blanks. https://api.gbif.org/v1/species/match?name=Arthopyrenia%20dispersa Example : GBIF : Arthopyrenia dispersa J.Lahm ex Körb. COL : Arthopyrenia dispersa J. Lahm ex Körb. Species Fungorum : Arthopyrenia dispersa J. Lahm ex Körb. As you see the blank between J. and Lahm is missing. There are many taxon authorities where this is the case. Armand Turpel
