Arbuscular mycorrhizal fungi are ubiquitous in field soils, as are mycophagous animals such as Collembola. It has been suggested that these animals reduce the functioning of the mycorrhiza and are thus detrimental to plant growth. However, recent choice experiments suggest that Collembola preferentially feed on nonmycorrhizal fungi in the rhizosphere. If these preferences also occur in field soils, then Collembola might indirectly benefit plants through an enhancement of mycorrhizal functioning and indirect multitrophic links to foliar-feeding insect herbivores.
丛枝菌根真菌在田间土壤中普遍存在，以真菌为食的动物如弹尾虫也是如此。有人认为这些动物会降低菌根的功能，从而对植物生长不利。然而，最近的选择实验表明，弹尾虫优先取食根际的非菌根真菌。如果这些偏好也出现在田间土壤中，那么弹尾虫可能会通过增强菌根功能以及与取食叶片的植食性昆虫的间接多营养联系而间接地使植物受益。
