speciaties

Speciaties is a term encountered in some biodiversity and data-science contexts to denote a unit of biodiversity that resembles a species but is defined using integrative, data-driven criteria rather than formal taxonomic rules. It is not part of formal nomenclature and is not universally adopted.

Speciaties are typically delineated by integrating genetic divergence, morphological differentiation, ecological niche, and geographic patterns. Delimitation methods may include molecular phylogenetics, population genomics, and ecological niche modeling. Because speciaties are not formal taxa, their boundaries are provisional and may be revised as new data become available.

They differ from species in that they function as operational units rather than formal names; they may reflect cryptic diversity or uncertain taxonomy. They can assist in rapid biodiversity assessments and conservation planning, particularly for groups with complex or rapidly changing diversity.

Criticism and context: some scholars argue that speciaties risk instability in nomenclature and complicate conservation frameworks that rely on formal species designations; others view them as a flexible, data-driven approach to delimitation that can complement traditional taxonomy.

Examples: in plant and insect studies, speciaties have identified distinct lineages supported by genetic and ecological data, though further taxonomic work is often needed to determine whether a speciaty should be described as a species.
