As a guideline NOW uses the taxonomy of McKenna & Bell's
Classification of Mammals Above the Species Level, except for Muridae for which we use McKenna & Bell's classification with the modifications
suggested by Hans de Bruijn.
Practices related to data entry
- If the family (or subfamily) is not known at data entry (a relatively common occurrence) the value 'Findout' may be
used. These species can be listed and updated later.
- Taxonomic devices like 'cf.', 'aff.', 'ex gr.' no longer exist as such in the database, but have instead become attributes of individual occurrences of the taxon,
indicated by ID status, or attributes of all instances of the taxon, indicated by taxonomic status. The Additional Info field in the
Locality > Species tab (also visible in 'Loc-Sp Info' within Species records) may be used in these cases to mark what was written in the original document.
- It is important to think about the intention of the author when entering new species into the database or existing species into a locality. Please familiarise yourself with our
guidelines and examples under Taxonomic Fields and Species at Localities.
- Before entering a new species into the database, please make sure that it does not already exist under another genus name in the same family! You can search for
this by inputting the correct family and species names into the 'Species' list search fields. If this appears to be the case, see instructions under
'Taxonomy - Synonyms'. In any other (possible) synonymy cases, please contact Susanna Sova
or Laura Säilä before entering a new synonym into the database.
