Extra Material for Chapter 4A: How to estimate functional diversity indices
Example Altitudinal Gradient 

There are 11 files for Chapter4A:

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

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

3.File trait by spp Altitudinal Gradient.IDB2: InfoStat file with information about trait values of species along the altitudinal gradient.

4.File trait by spp Altitudinal Gradient with PFT.IDB2: InfoStat file with information about trait values of species along the altitudinal gradient and the information about plant functional type each species belong.

5.File spp by plot Altitudinal Gradient.IDB2: InfoStat file with information about presence of tree species in the altitudinal gradient including abundance and basal area.

6. File trait by spp Altitudinal Gradient.FDDB: FDiversity file with information about species trait values along the altitudinal gradient.

7.File spp by plot Altitudinal Gradient.FDDB: FDiversity file with information about presence of tree species in the altitudinal gradient including abundance and basal area.

8.File Concat spp by plot Altitudinal Gradient.FDDB: FDiversity file with merging information about trait values and species abundance by along an altitudinal gradient.

9.File Concat Altitudinal Gradient with PFT.FDDB: FDiversity file with merging information about trait values and species abundance by along an altitudinal gradient, including plant functional types.

10.File Res indices with ba.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.

11.File Res indices with freq.FDDB: FDiversity file with functional diversity indices estimated using frequency (number of individuals for 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).
