Table 3. Mean nematode abundance and diversity indices by depth (± standard deviation).
| Location | Depth (cm) | Abundance | Richness (Genera) | Evenness | Shannon diversity | Maturity index (MI) |
|---|---|---|---|---|---|---|
| Transects (0.5–2 m distance) | 0‒5* | 445.5 ± 191.0A | 14.4 ± 3.6 A | 0.7 ± 0.1 | 1.9 ± 0.3 | 1.9 ± 0.2 A |
| 30‒35* | 148.3 ± 209.7B | 8.9 ± 2.9 B | 0.8 ± 0.2 | 1.6 ± 0.6 | 2.3 ± 0.4 B | |
| Grave (0 m distance) | 0‒5 | 480.6 ± 191.9 A | 10.3 ± 2.0 A | 0.7 ± 0.1 | 1.7 ± 0.2 | 1.8 ± 0.2 |
| 30‒35 | 480.0 ± 306.2 A | 7.7 ± 2.1 AB | 0.4 ± 0.2 | 0.8 ± 0.4 | 2.1 ± 0.1 | |
| 40‒45 | 352.0 | 8.0 | 0.8 | 1.7 | 1.5 | |
| 70‒75 | 25.0 ± 26.1 B | 4.0 ± 4.1 B | 0.7 ± 0.5 | 0.9 ± 0.9 | 1.7 ± 0.5 | |
| 85‒90 | 0.0 | 0.0 | 0.0 | 0.0 | n/a |
Significant differences between depths are indicated in bold and superscript letters designate groups that are not significantly different from each other (within either transects or grave) based on the Tukey HSD post hoc test.
*Data for transects represent the mean of samples from all distances (0.5, 1.0, 1.5 and 2.0 m) in all three transects (n = 18: 0‒5 cm, n = 15: 30‒35 cm), as there was no statistically significant difference with distance from grave.
