Habitat heterogeneity is an important driver of aboveground species diversity but few studies have investigated effects on soil communities. Trees shape their surrounding by both leaf litter and roots generating small scale heterogeneity and potentially governing community patterns of soil organisms. To assess the role of vegetation for the soil fauna, we studied whether tree species (Fagus sylvatica L., Acer pseudoplatanus L., Fraxinus excelsior L., Tilia cordata Mill.), markedly differing in… Expand
Leaf litter identity rather than diversity shapes microbial functions and microarthropod abundance in tropical montane rainforests
Results provide evidence that decomposition and microbial biomass in litter respond to leaf litter diversity as well as litter identity (chemical and physical characteristics), while microarthropods respond only to litter identity but not litter diversity. Expand
Morpho-ecological structure of oribatid mite (Acariformes, Oribatida) communities in the forest litter of recultivated areas
The obtained results expand the understanding of the role of oribatid mites in the processes of ecological rehabilitation of disturbed ecosystems in the conditions of modern nature management. Expand


Oribatid mite community structure and tree species diversity: A link?
The results suggest that oribatid mite community structure is minimally affected by tree species diversity and associated changes in litter diversity. Expand
Does plant species co-occurrence influence soil mite diversity?
The results indicate that grasses in diculture supported a more species and phylogenetically rich soil mite fauna than was observed for monocultures and that this relationship was significant at depth but not in the upper soil horizon. Expand
Oribatid mites (Acari: Oribatidae) are the most diverse arthropod group in forest litter and soil, and they make significant contributions to decomposition as microbial grazers and saprophages. As isExpand
Mixed leaf litter effects on decomposition rates and soil microarthropod communities in an oak–pine stand in Japan
Faunal abundance in litter bags was higher in mixed-species litter than in those with single- species litter, and species richness of oribatid mites was also higher in the three-species mixed litter, which seemed to be responsible for the more abundant soil microarthropod community. Expand
The influence of plant litter diversity on decomposer abundance and diversity
Litter mixing effects on the abundance and diversity of decomposer biota, when they occur, are likely to be of secondary and generally minor significance when compared to the effects of litter species identity and composition. Expand
Biodiversity at the plant–soil interface: microbial abundance and community structure respond to litter mixing
The data provide support for both the increased abundance hypothesis and the altered microbial community hypothesis, and microbial changes do not translate to predictably altered litter decomposition and may only produce synergisms when mixed litters are functionally similar. Expand
Tree species influence on microbial communities in litter and soil: Current knowledge and research needs
The evidence that tree species influence the composition of the microbial communities in decomposing litter, forest floors, soil and the rhizo/mycorrhizosphere is examined to definitively deduce the influence of tree species. Expand
Litter complexity and composition are determinants of the diversity and species composition of oribatid mites (Acari: Oribatida) in litterbags
Results indicate a link between heterogeneity and diversity of mites active in a particular horizon of litter and some influence of litter-type upon species composition, though not conclusive evidence of the ultimate role of heterogeneity in maintaining the diversity of oribatid mites. Expand
Tree identity surpasses tree diversity in affecting the community structure of oribatid mites (Oribatida) of deciduous temperate forests
Results suggest that large and strongly sclerotized oribatid mite species, such as Steganacarus magnus and Chamobates voigtsi , benefited from the presence of ash and lime, indicating that these large species better resist harsh microclimatic conditions in shallow organic layers. Expand
Leaf litter species identity influences biochemical composition of ectomycorrhizal fungi
It is suggested that the biochemical composition of ECM fungi is a fungal response trait, sensitive to environmental changes such as shifts in leaf litter species, as well as a dynamic response of the fungal proteome to soil nutritional changes. Expand
