Table 1. Estimated parameters associated with the neutral model of biodiversity fit at the level of Scotland for bacterial and fungal communities described within each soil layer.
| Response matrix | Soil layer | Theta | I (median) | I (IQR) |
|---|---|---|---|---|
| Bacteria | 1 | 34.68 | 18.60 | 12.25 |
| 2 | 40.57 | 14.43 | 10.67 | |
| 3 | 40.51 | 10.12 | 9.37 | |
| 4 | 44.46 | 11.88 | 11.02 | |
| Fungi | 1 | 54.79 | 7.71 | 8.74 |
| 2 | 36.13 | 2.87 | 4.91 | |
| 3 | 16.49 | 1.10 | 2.59 | |
| 4 | 17.47 | 0.80 | 2.17 |
I, immigration; IQR, interquartile range; theta, biodiversity.
Theta is estimated for the entire metacommunity while I is estimated for each local community; the central tendency and dispersion of the distribution across communities is represented by the median and IQR, respectively.
