Abstract Biodiversity is a major driver of numerous ecosystem functions. However, consequences of changes in forest biodiversity remain difficult to predict because of limited knowledge about how tree diversity influences ecosystem functions. Litter decomposition is a key process affecting nutrient cycling, productivity, and carbon storage and can be influenced by plant biodiversity. Leaf litter species composition, environmental conditions, and the detritivore community are main components of… Expand
Leaf litter identity rather than diversity shapes microbial functions and microarthropod abundance in tropical montane rainforests
TLDR
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

Soil animals alter plant litter diversity effects on decomposition.
TLDR
The data show that litter species richness and soil fauna interactively determine rates of decomposition in a temperate forest, suggesting a combination of bottom-up and top-down controls of litter diversity effects on ecosystem C and nutrient cycling. Expand
Partitioning the effect of composition and diversity of tree communities on leaf litter decomposition and soil respiration
TLDR
Insight is provided into the effect of loss of tree diversity in forests on soil processes, essential to predicting changes in the global carbon budget brought on by biodiversity loss. Expand
Plant litter functional diversity effects on litter mass loss depend on the macro-detritivore community.
TLDR
The results show that the effects of litter functional diversity on decomposition are contingent upon the macro-detritivore community and composition, and conclude that the temporal dynamics of litter trait diversity effects and their interaction with detritivor diversity are key to advancing the understanding of litter mass loss in nature.

Tree functional diversity affects litter decomposition and arthropod community composition in a tropical forest
TLDR
It is demonstrated that the mesocosms represent an effective approach to link studies of litter decomposition and arthropod communities, and indicates that changes in the functional diversity of litter could have wider implications for arthropode communities and ecosystem functioning in tropical forests.

Functional leaf traits and biodiversity effects on litter decomposition in a stream.
TLDR
Evidence was weak in support of the idea that functional litter dissimilarity matters, in spite of plausible mechanisms that could cause such effects, across decay categories. Expand
Biodiversity and Litter Decomposition in Terrestrial Ecosystems
▪ Abstract We explore empirical and theoretical evidence for the functional significance of plant-litter diversity and the extraordinary high diversity of decomposer organisms in the process ofExpand
Functional diversity affects decomposition processes in experimental grasslands
TLDR
The predominance of functional diversity rather than of species richness effects suggests that profound knowledge on functional attributes of plant species is the key to understand and to predict biodiversity-decomposition relationships. Expand
Plant Diversity Impacts Decomposition and Herbivory via Changes in Aboveground Arthropods
TLDR
Assessing aboveground decomposer and herbivore communities and linking their abundance and diversity to rates of decomposition and Herbivory showed that increasing plant diversity led to higher abundance and Diversity of decomposing arthropods through higher plant biomass and C:N ratio, leading to higher herbivory rates.

Tree species richness affects litter production and decomposition rates in a tropical biodiversity experiment
TLDR
There are no coherent and general effects of tree species richness on both litter production and decomposition from a manipulative biodiversity experiment with trees in tropical Panama, which has been designed to explore the relationship between tree diversity and ecosystem functioning. Expand
Tree identity rather than tree diversity drives earthworm communities in European forests
TLDR
This study advanced the understanding of the mechanisms driving tree identity effects and supported previous findings that litter quality, as a proxy of tree identity, was a stronger driver of earthworm species richness and biomass than tree diversity. Expand
