Plant diversity effects on soil heterotrophic activity in experimental grassland ecosystems
TL;DR: The presence of nitrogen fixers seemed to be the most important component of the plant diversity manipulation for soil heterotrophs, and reduction in plant biomass due to the simulated loss of plant species had more pronounced effects on voles and earthworms than on microbes.
Journal ArticleDOI
Protozoa, Nematoda and Lumbricidae in the rhizosphere of Hordelymus europeaus (Poaceae): faunal interactions, response of microorganisms and effects on plant growth
TL;DR: It is concluded that nematodes and protozoa stimulated plant growth by non-nutritional effects, whereas the effects of earthworms were caused by an increase in nutrient supply to H. europaeus.
Journal ArticleDOI
Microbial-faunal interactions in the rhizosphere and effects on plant growth
TL;DR: In this paper, the role of the soil fauna interacting with rhizosphere micro-organisms and plant roots has been investigated, and it is shown that the interaction between plant roots, root exudates, and microorganisms can only be understood in relation to soil faunal activity.
Journal ArticleDOI
Effects of plant diversity on Collembola in an experimental grassland ecosystem
TL;DR: The results suggest that microbivorous soil invertebrates are controlled by food quality rather than quantity and indicate that presence of certain plant species and functional groups may be more important for collembolan community structure than the diversity of plant speciesand functional groups per se.
