Download as PPTX, PDF2 likes3,568 views
The document discusses the application of Answer Set Programming (ASP) to model the principles of taxonomic and nomenclatural change in biodiversity. It presents a structured framework using ASP to simulate nomenclatural rules, showing how these principles can be represented and computed effectively. The conclusion emphasizes that ASP is a viable tool for representing nomenclature rules, managing taxonomic changes, and could enhance the stability of taxonomic nomenclature.
![Core principles embodied in the Code of Zoological Nomenclature
1. Binominal Nomenclature
• The scientific name of a species, and not of a taxon at any other rank, is a combination of two names.
2. Priority
• The valid name of a taxon is the oldest available name applied to it.
3. Coordination
• Within the [family, genus, species] group, a name established for a taxon at any rank is simultaneously
established with the same author/date for taxa with the same name-bearing type at other ranks in the group.
4. First Reviser
• The relative precedence of two or more names or nomenclatural acts published on the same date, or of
different original spellings of the same name, is determined by the First Reviser.
5. Homonymy
• The name of each taxon must be unique.
6. Typification
• Each nominal taxon in the family group, genus group or species group has a name-bearing type fixed to
provide the objective standard of reference by which the application of the name is determined.
7. [Gender Agreement]
• Agreement in grammatical gender between a generic name and Latin or latinized adjectival or participial
species-group names combined with it originally or subsequently.

- 13. 9-taxon use case – transition model
- 14. Input (original) taxonomy at t = 0 ["9-name/taxon use case"] • All type bearing and non-type bearing epithets have different publication years t=0 * = type-bearing name Transition: exactly 1 species will move to the other genus at t = 1. Since there are 4 species, this yields 4 Stable Models.
- 15. Model 1: O. secundus moves into Agenus • Requires new higher-level synonymies, "cascading", new names, new types t=0 t=1 Required nomenclatural changes; O. secundus is a type bearer.
- 16. Model 2: A. tertius moves into Ogenus • Non-type bearer – 1 taxonomic change ↔ 1 new combination t=0 t=1
- 17. Model 3: O. quartus moves into Agenus • Non-type bearer – 1 taxonomic change ↔ 1 new combination t=0 t=1
- 18. Model 4: A. primus "moves" [Ogenus spp. ingress into Agenus] • Most dramatic nomenclatural adjustments – A. primus is globally oldest type t=0 t=1 Two species (names) – secundus & quartus – move into Agenus.
- 19. Modeling in ASP Does it work? It does.

Priority = Principles currently modeled. • The valid name of a taxon is the oldest…. 3.

- 22. ASP code sample – modeling priority, new combination, synonymy
- 23. Next up – improved output visualization, more complex cases • "20-name/taxon use case" can include 36 *one-species-moves* permutations • Compute, tabulate, visualize complete set of nomenclatural changes for each • At the genus level, moving entire non-type genera requires no name change
- 24. Conclusions & outlook 1. This work is a novel representation of the Principles of Nomenclature in a formal logic system with default conditions and transitional properties. 2. The model can be elaborated to include an increasing wide range of taxonomic / nomenclatural change scenarios, and specific rule exceptions. 3. ASP could be utilized to validate proposed nomenclatural emendations or infer additional required changes, and implemented in a nomenclatoral repository such as ZooBank. 4. In complex change scenarios, ASP could be used to perform optimizations and minimize nomenclatural instability given the need to move one or more taxa.
