Extra Material for Chapter 4B: How to estimate functional diversity indices
Example Chronosequence 

There are 12 files for Chapter4B:

1.This readme first chronosequence.txt file with information about the other files

2.File Species along Chronosequence.xls: Excel file six sheets having information about traits values and species presence used to defined Plant Functional Groups, estimate functional diversity indices and its relationships with the chronosequence. 

3.File Trait by spp Chronosequence.IDB2: InfoStat file with information about trait values of species for the chronosequence.

4.File Trait by spp Chronosequence for PCoA.IDB2: InfoStat file with information about trait values of species and the transformation of nominal and ordinary variables into new dummy and indicator variables to perform principal coordinate analysis.

5.File Trait by spp Chronosequence with PFT.IDB2: InfoStat file with information about trait values of species along the chronosequence and the information about plant functional type each species belong.

6.File spp by plot Chronosequence.IDB2: InfoStat file with information about presence of species in plots along the chronosequence including abundance and basal area.

7.File Concatenated Chronosequence.IDBD: InfoStat file with information about presence of species in plots along the Chronosequence and its trait values 

8.File Trait by spp Chronosequence.FDDB: FDiversity file with information about trait values of species for the chronosequence.

9.File spp by plot Chronosequence.FDDB: FDiversity file with information about presence of species in plots along the chronosequence including abundance and basal area.

10.File Concatenated Chronosequence.FDDB: FDiversity file with information about presence of species in plots along the Chronosequence and its trait values 

11.File Results Chronosequence with abundance.FDDB: FDiversity file with functional diversity indices estimated using abundance (number of individuals for each species in the plot) as weighted variable.

12.File Results Chronosequence with basal area.FDDB: FDiversity file with functional diversity indices estimated using basal area (sum of the basal area for the total number of individuals of each species in the plot) as weighted variable.


To open InfoStat files you have to download and install InfoStat statistical software from www.infostat.com.ar . There is a free version (with small limitations for saving results) and a professional version with no restrictions. The entire example may be run using the free version. 

To open FDiversity files you have to download FDiversity software from www.fdiversity.nucleodiversus.org and install it following the tutorial of Section 4.1 or the instructions you will find in the User Manual (available from FDiversity Help menu and/or the web page).
