However, we still have a limited understanding of the consequences of earthworm casting activity on nematode communities, and the role played by the land use in this relationship. Therefore, the main objective of this study was to compare the effect of the anecic earthworm Amynthas adexilis (Thai, 1984) on the structure of nematode communities, in a woodland and meadow presenting different soil organic C content in northern Vietnam. Nematode population and physico-chemical properties of casts produced by the anecic earthworm A. adexilis and adjacent soil presenting no recent earthworm activity (0-10 cm deep) were characterized. A. adexilis incorporated organic matter into its casts compared to the adjacent bulk top soil horizon, reflected by a significant increase of the organic carbon and nitrogen contents (1.4 times more in the meadow and 1.8 times more in the woodland). Earthworm casts contained 2.6 and 1.7 times more nematodes than the adjacent top soil, in meadow and woodland, respectively. The effect of earthworm casting activity on nematode community structure was similar in both land uses. Compared to the soil, casts were significantly enriched in all trophic groups (between 1.9 and 11.6 times more in casts in the meadow, and between 1.6 and 23.7 times more in casts in the woodland, depending on the trophic group), except for obligate plant feeders that were under-represented (1.4 times less in casts for both land uses). The plant parasitic index decreased in the casts compared to the soil, indicating an environment less favourable for plant parasitic nematodes. specialized VIET NAM 076 068 27 e01565 [7 ] 2021 2351-9894 https://www.documentation.ird.fr/hor/fdi:010081240 10.1016/j.gecco.2021.e01565 Get 2351-9894 [F B010081240] https://www.documentation.ird.fr/hor/fdi:010081240 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers21-04/010081240.pdf IRD - Base Horizon / Pleins textes 2021-04-19 2025-03-26 fdi:010081240 fre
