3. Topics Introduction Taxonomic data Observation data Identification Vegetation data standards VegBank Data archiving and sharing

4. 1. Taxonomic database challenge: Standardizing taxa The problem: Integration of data potentially representing different times, places, investigators and taxonomic standards. The traditional solution: A standard list of organisms / communities.

5. USDA Plants & ITIS Abies lasiocarpa var. lasiocarpa var. arizonica One concept ofAbies lasiocarpa

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

7. NameReferenceConcept Taxonomic theory A taxon concept represents a unique combination of a name and a reference. Report -- name sec reference..

8. Relationships among concepts allow comparisons and conversions Congruent, equal (=) Includes (>) Included in (<) Overlaps (><) Disjunct (|) and others …

10. Andropogon virginicus complex in the Carolinas 9 elemental units; 17 base concepts

11. Standardized taxon lists fail to allow dataset integration The reasons include: Taxonomic concepts are not defined (just lists),Taxonomic concepts are not defined (just lists), Relationships among concepts are not definedRelationships among concepts are not defined The user cannot reconstruct the database as viewed at an arbitrary time in the past,The user cannot reconstruct the database as viewed at an arbitrary time in the past, Multiple party perspectives on taxonomic concepts and names cannot be supported or reconciled.Multiple party perspectives on taxonomic concepts and names cannot be supported or reconciled.

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

13. Carya carolinae-septentrionalis NCURABUSDACVS Add USDA PLANTS records & CVS vegetation plot data

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

15. How to merge records that may be based on different concepts??

To do otherwise would be to introduce false positives.

19. Taxonomic standards TDWG, TCS SEEK, TOS GUIDs, DOIs, LSISs IPNI

20. 2. Observation data TDWG proposal NatureServe EOs & Cornell bird data Basics –Place, time, protocol, taxa, attributes Plots constitute a subset Museum collections constitute a subset

21. A name in a publication could be either a concept or an identification. Identifications should include linkage to at least one concept, but need not be limited to a single concept. Eg. -- < Potentilla sec. Cronquist 1991 + ~ Potentilla simplex sec Cronquist 1991 + ~ Potentilla canadensis sec Cronquist 1991 3. Identifications

22. 1.Absolutely wrong 2.Understandable but wrong 3.Acceptable but not typical 4.Good fit 5.Ideal, typical Uncertainty

23. FGDC, ESA, IAVS VegBank XML VegetWeb IAVS: 24-27 April @ NESCent EML –Supports blocks of data –No concepts, no identification uncertainty 4. Vegetation data standards

24. 5.VegBank The ESA Vegetation Panel has developed VegBank-- a public archive for vegetation plots (http://vegbank.org).http://vegbank.org VegBank is expected to function for vegetation plot data in a manner analogous to GenBank. Primary data will be archived for future reference, novel synthesis, and reanalysis. The database architecture is compatable with most types of species co-occurrence data.

25. VegBank data are open access All data placed in VegBank are available to the public at no charge (unless the plot contributor places restrictions to protect location information for rare and endangered species or private lands). Key data can be viewed by a simple web link. The following link shows information for two VegBank plots: http://vegbank.org/get/std/observation/5153,5906
