Unique Identifiers: improving the database for data science

Maybe I’m misinterpreting what you’re saying, but this is not correct. Whilst all V. peregrina ssp. peregrina fall within V. peregrina, the opposite is not true. The existence of a nominate subspecies implies that there must also be other subspecies, in which case some observations of V. peregrina may correspond to this other infraspecific entity. So they do not represent the same entity.
