Summary of the response of soil organism diversity and composition at two depths (0–10 cm, 11–20 cm) to the two axes of experimental meadow treatments: diversity and height
| Measure | Effect | ||
|---|---|---|---|
| Diversity | Height | Interaction | |
| Soils, 0–10 cm | |||
| PLFA composition PC1 | yes | yes | |
| PLFA composition PC2 | yes | yes | |
| Bacterial DNA alpha diversity | |||
| Fungal DNA alpha diversity | ↑ | ||
| Bacterial DNA composition BC | yes | ||
| Fungal DNA composition BC | yes | yes | |
| Soils, 11–20 cm | |||
| PLFA composition PC1 | yes | yes | |
| PLFA composition PC2 | yes | yes | |
| Bacterial DNA alpha diversity | ↓ | ||
| Fungal DNA alpha diversity | ↓ | ||
| Bacterial DNA composition BC | yes | ||
| Fungal DNA composition BC | yes | ||
Significant effects for compositional change are indicated by “yes.” Significant effects for alpha diversity are designated with a symbol indicating the direction of effect; an up arrow indicates the response variable increases with increasing meadow height/diversity, a down arrow indicates the response variable decreases with increasing meadow height/diversity. Full results are in Table 4.
