  1. The challenge of organism identity --- The flora of the Southeast as a case study • Robert K. Peet • University of North Carolina Ecological Society of America Vegetation Panel • SEEK development team • SERNEC RTN

  2. Biodiversity documentation depends on accurate identification of organisms • Accurate identification and labelling of organisms is a critical part of collecting, recording, and reporting biological data. • Increasingly, research depends on the integration and re-use of multiple datasets. • Traditional Linnaean nomenclature is insufficient

  3. One concept ofAbieslasiocarpa USDA Plants & ITIS Abies lasiocarpa var. lasiocarpa var. arizonica

  4. A narrower concept of Abies lasiocarpa Flora North America Abies lasiocarpa Abies bifolia Partnership with USDA plants to provide plant concepts for data integration

  5. High-elevation fir trees of western North America AZ NM CO WY MT AB eBC wBC WA OR Distribution Abies lasiocarpa var. arizonica Abies lasiocarpa var. lasiocarpa USDA - ITIS Abies lasiocarpa Abies bifolia Flora North America A B C Minimal concepts

  6. Andropogonvirginicus complex 9 elemental units; 17 base concepts, 27 scientific names

  7. Standardized taxon lists failto allow dataset integration • The reasons include: • Taxonomic concepts are not defined (just lists of names), • Multiple party perspectives on taxon concepts and names are not supported • The user cannot reconstruct the database as viewed at an arbitrary time in the past. • The single largest impediment to large-scale synthesis in biodiversity & ecology.

  8. A Case Study:Flora of the Southeastern US • Regional floras obsolete and incomplete • Need for an updated atlas of the flora of the Southeast • Datasets with inconsistent taxonomic concepts have defied integration • SERNEC has a goal of integrating collections across the region • 65,000 concept relationships already mapped

  9. How have things changed? Concept relationships of Southeastern US plants treated in different floras. Based on > 65,000 concept relationshipshttp://herbarium.unc.edu/flora.htm

  10. The Opportunity Multiple groups are building IT tools but lack data to populate the tools We have a critical mass of taxon concepts and concept relationships SERNEC organization provides a community approach Potential for SERNEC to establish best practices and set standards

  11. Toward a new Atlas http://herbarium.unc.edu/seflora/firstviewer.htm How to integrate new sources of data?? Carya carolinae-septentrionalis, Radford et al. 1968

  12. Add static database records & dynamic access to museum collections NCU RAB USDA CVS Carya carolinae-septentrionalis

  13. But wait !!There is a concept issue • According to Radford 1968, USDA PLANTS v 4.0, & Weakley 2005 • Carya carolinae-septentrionalis • Carya ovata • According to Stone 1997 in FNA • Carya ovata var australis • Carya ovata var. ovata

  14. Some nominal occurrences might or might not represent the taxon Carya carolinae-septentrionalis

  15. Next steps? Software: • Allow user to select a taxonomic perspective (e.g., Weakley, PLANTS, or FNA) • Allow user to select date-specific version of Databases. • Data integration tools and services Data needs: • Comprehensive map of relationships taxonomic concepts • Identify observation records to concept

  16. The way ahead • Publications, datasets, and museums identify taxa to concepts. • Databases and data services document core sets of taxonomic concepts and the relationships of those concepts to each other.
