1. Ecological stoichiometry predicts important control of the relative abundance of the key elements carbon (C), nitrogen (N) and phosphorus (P) on trophic interactions. In a nutrient-poor Amazonian lowland rain forest of French Guiana, we tested the hypothesis that decomposers exploit stoichiometrically diverse plant litter more efficiently, resulting in faster litter decomposition compared to litter with a uniform stoichiometry. 2. In a field experiment in the presence or absence of soil… Expand
Nutrient and Carbon Limitation on Decomposition in an Amazonian Moist Forest
Tropical forests determine global biogeochemical cycles to a large extent, but control factors for key ecosystem processes such as decomposition remain poorly understood. With a full-factorial CExpand
C, N and P fertilization in an Amazonian rainforest supports stoichiometric dissimilarity as a driver of litter diversity effects on decomposition
TLDR
It is indicated that litter stoichiometric dissimilarity drives mixture effects via the nutritional requirements of soil fauna through which species decompose faster as a group of different species. Expand
Distinct Microbial Limitations in Litter and Underlying Soil Revealed by Carbon and Nutrient Fertilization in a Tropical Rainforest
TLDR
The data suggest that increased nutrient enrichment in the studied Amazonian rainforest can considerably change microbial activity and litter decomposition, and that these effects differ between the litter layer and the underlying soil. Expand
Soil fauna promote litter decomposition but do not alter the relationship between leaf economics spectrum and litter decomposability
TLDR
This study advances the understanding of the soil fauna in driving litter decomposition in subtropical forests by finding significant linear relationships between LES and litter mass or carbon loss, but not nitrogen loss. Expand
Litter inputs drive patterns of soil nitrogen heterogeneity in a diverse tropical forest: results from a litter manipulation experiment
Abstract Plant functional traits affect soil nutrient cycling in many ecosystems, but high levels of diversity make it challenging to identify their influence in tropical rainforests. Here, we used aExpand
Effects of soil fauna on litter decomposition using field microcosms across 16 co-occurring temperate tree species
ABSTRACT Litter decomposition is an important part of the carbon and nutrient cycles in terrestrial ecosystems. However, understanding of the contribution of soil fauna to litter decomposition andExpand
Is litter decomposition enhanced in species mixtures? A meta-analysis
Litter decomposition is a key process in the carbon balance of soils. Commonly, plant litters occur in mixtures where the species differ in quality traits such as the nutrient concentration andExpand

Nutrient regulation of organic matter decomposition in a tropical rain forest.
TLDR
Results show that, while nutrients may not affect mass loss during decomposition in nutrient-poor, wet ecosystems, they may ultimately regulate CO2 losses (and hence C storage) by limiting microbial mineralization of DOM leached from the litter layer to soil. Expand
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
Multiple nutrients limit litterfall and decomposition in a tropical forest.
TLDR
Tropical forests are a non-Liebig world of multiple nutrient limitations, with at least four elements shaping rates of litterfall and decomposition, and multiple metallomic enzymes and cofactors likely create gradients in the break down of leaf litter. Expand
NUTRIENT LIMITATION OF DECOMPOSITION IN HAWAIIAN FORESTS
TLDR
Fertilization affected litter nutrient dynamics more strongly than it did decomposition, and uptake of both N and P by decomposers that was not always accompanied by changes in decomposition rates, suggesting nutrient incorporation into decomposing litter may retain nutrients within ecosystems, even when nutrients do not limit decomposition rate. Expand
Links between plant litter chemistry, species diversity, and below-ground ecosystem function
TLDR
It is shown that soil C and N cycling during decomposition are controlled by the composition and diversity of chemical compounds within plant litter mixtures, rather than by simple metrics of plant species diversity. Expand
The influence of plant litter diversity on decomposer abundance and diversity
TLDR
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
Phosphorus Limits Tropical Rain Forest Litter Fauna
TLDR
The density of the invertebrate litter fauna varied considerably, and was strongly tied to soil and litter phosphorus concentrations, and natural variation in nutrient levels can serve as a predictor of density in a highly diverse tropical animal community. Expand
Controls over foliar N:P ratios in tropical rain forests.
TLDR
Any use of N:P ratios in the tropics to infer larger-scale ecosystem processes must comprehensively account for the diversity of any given site and recognize the broad range in nutrient requirements, even at the local scale. Expand
