In biology, the Author of the scientific name of a taxon is the person or team who first makes the name available by using it in a scientific publication with a description of the taxon to which it applies.
the Family Group, covering taxa at the ranks of superfamily, family, subfamily, tribe, subtribe, and any other rank below superfamily and above genus
the Genus Group encompasses all taxa at the ranks of genus and subgenus.
the Species Group encompasses all taxa at the ranks of species and subspecies.
Within each group, the same authorship applies regardless of the taxon level to which the name (with, in the case of the Family Group, the appropriate variable ending) is applied. In strict taxonomical works the author and the date of publication will be appended to the taxon name to ensure clarity of the sense in which a taxon name is being used.
The use of brackets around the authorship of a species name indicates that the author made the specific name available but considered it part of a different genus (in this case, Linnaeus classified it as Papilio atalanta).
Botany
The International Code of Botanical Nomenclature does not use level groups. Names at every level can have distinct authorship. This extends up to class (or even to division), and down to variety, form and subform.
It has always seemed to me that the many parts that make up the subject of biology are related to each other more like the nodes of a web than as a linear collection of independent topics.
Another disadvantage of printed textbooks is the inevitable delay between the time that new advances in biology are reported and the time that they can become incorporated in a printed book (often several years).
The first edition of Kimball's general biology text was published in 1965.
