Building a regional database of taxonomic concepts.
There is an increasing recognition of the need to clarify and explicitly communicate the taxonomic circumscriptions or concepts in all usages of scientific names, including monographs, floras, species lists, ecological sampling, legal applications, and online data compilations. The recognition that “names are not enough” has become codified in recently promulgated standards, but robust and extensive examples of how to implement this through the development and application of concept-based taxonomy are few. We here present a large example of taxonomic concept-mapping for the vascular flora of the Southeastern United States, wherein more than 6000 taxa and more than 2500 taxonomic works have been “mapped” to a single “accepted taxonomy.” The optimal way forward, though, appears to be through recognition of Least Divisible Taxonomic Units, and a mechanism for their flexible aggregation into the taxa recognized in important taxonomic schemas. This method allows for change over time, application of differing taxonomic standards, both maximal precision and flexibility of detail, and identification and annotation of individual specimens, allowing much more accurate and useful data aggregation than is currently possible.
