Description

The data.txt file is a tab-delimited file. It contains a list of studies used in the meta-analysis, including type of CO2 treatment, dominant vegetation, and values for mean ambient and mean elevated activity for the various enzyme groups.

Column definitions

1. Study citation

2. Type of CO2 treatment

3. Length of CO2 treatment

4. Dominant Vegetation

5. Treatment (Elevated or Ambient)

6. Simple Sugar Degradation

7. Starch Degradation

8. b-glucan Degradation

9. Cellulose Degradation

10. Xylan/Hemicellulose Degradation

11. Lignin Degradation

12. Chitin Degradation

13. Protein Degradation

14. Organic P Degradation

15. Organic S Degradation

Missing values are represented as “-9999”.

Checksum values are (calculations do not include “-9999” for missing values):

Column 6 (Simple Sugar Degradation): SUM= 35031.1; 126 missing values (rows with data: 32)

Column 8 (b-glucan Degradation): SUM= 24891.97; 102 missing values (rows with data: 56)

Column 11 (Lignin Degradation): SUM= 29411.038; 120 missing values (rows with data: 38)

Column 15 (Organic S Degradation): SUM= 1053.8; 130 missing values (rows with data: 28)
