1. NutNet data update 15 Aug 2011 Data management update
Taxonomic resolution update

3. Normalized data
From Wikipedia:
“Codd's twelve rules” are a set of thirteen rules (numbered 0-12) proposed by Edgar F. Codd, a pioneer of the relational model for databases…

* data are stored,
inserted,
changed,
and deleted in ONLY ONE PLACE.
* New data adds rows, not columns.

4. Site
Site_Name 1
XYZ 2
PDQ 1 2
Borer, Seabloom et al Bulletin of the Ecological Society of America 90:205–214

5. Places & people
Observed plant taxa
Units of Observation
Observed Data
NutNet relational database
Supported by U of M MSI

6. Taxon observations Connect to site
Taxonomy presents a common challenge to large ecological datasets
Species are the terminal identity in a nested hirearchy, easily captured by relational db models
Lookup and intersection tables can connect single taxon identity to multiple local names
A lot of work has been done trying to reconcile the taxonomy

8. ~1860 plant names
~1739
unique taxon identifiers

9. The next target:
Further resolving NutNet phylogeny

13. NutNet Results are based on your data – QC is critical
* Note any data issues as you work
* Changes to data should be made in one place. Any changes, updates or deletions necessary to the raw NutNet data should be given in writing (preferably by ) to Eric Lind
* Examine species list in your folder; add or correct for completeness
