Comparison of nematode communities in anecic earthworm casts and adjacent soil reveal a land use-independent trophic group signature

By ingesting soil and organic matter in different horizons depositing casts on surface, anecic earthworms have large influence ecological processes. However, we still a limited understanding of the consequences earthworm casting activity nematode communities, role played by land use this relationship. Therefore, main objective study was to compare effect Amynthas adexilis (Thai, 1984) structure woodland meadow presenting C content northern Vietnam. Nematode population physico-chemical properties produced A. adjacent no recent (0–10 cm deep) were characterized. incorporated into its compared bulk top horizon, reflected significant increase carbon nitrogen contents (1.4 times more 1.8 woodland). Earthworm contained 2.6 1.7 nematodes than soil, woodland, respectively. The community similar both uses. Compared significantly enriched all trophic groups (between 1.9 11.6 meadow, between 1.6 23.7 depending group), except for obligate plant feeders that under-represented less uses). parasitic index decreased indicating an environment favourable nematodes.
