Abstract Litter decomposition is fundamental for nutrient and carbon (C) cycling, playing a major role in regulating the Earth's climate system. Climate change and fertilization are expected to largely shift litter decomposition rates in terrestrial ecosystems, however, studies contextualizing the relative importance of these major global change drivers versus other key decomposition drivers such as substrate quality and ecosystem type are lacking. Herein, we used two independent field… 
Nitrogen Deposition Effects on Soil Properties, Microbial Abundance, and Litter Decomposition Across Three Shrublands Ecosystems From the Mediterranean Basin
Atmospheric nitrogen (N) inputs in the Mediterranean Basin are projected to increase due to fossil fuel combustion, fertilizer use, and the exacerbation of agricultural production processes. Although
Ecosystem type drives tea litter decomposition and associated prokaryotic microbiome communities in freshwater and coastal wetlands at a continental scale.
Wetland ecosystems are critical to the regulation of the global carbon cycle, and there is a high demand for data to improve carbon sequestration and emission models and predictions. Decomposition of
The Dynamics of Mass Loss and Nutrient Release of Decomposing Fine Roots, Needle Litter and Standard Substrates in Hemiboreal Coniferous Forests
Litter decomposition is a key process that drives carbon and nutrient cycles in forest soils. The decomposition of five different substrate types was analyzed in hemiboreal coniferous forests,
Microbial processing of plant remains is co-limited by multiple nutrients in global grasslands.
Microbial processing of aggregate-unprotected organic matter inputs is key for soil fertility, long-term ecosystem carbon and nutrient sequestration and sustainable agriculture. We investigated the
Combined effects of soil fertility and vegetation structure on early decomposition of organic matter in a tropical riparian zone
Abstract Monitoring forests undergoing restoration is important to evaluate not only the development of trees, but also the recovery of ecosystem functions. The decomposition of the organic matter is
Herb litter mediates tree litter decomposition and soil fauna composition
Herb litter has a major role in accelerating carbon sequestration and nutrient cycling in temperate forests and future research should focus on the generality of the observed patterns.
Effects of soil fauna on litter decomposition in Chinese forests: a meta-analysis

Litter quality and climate have been presumed to be the dominant factors regulating litter decomposition rates on broad spatial scales. However, the role of soil fauna on litter decomposition is
Sensitivity of global soil carbon stocks to combined nutrient enrichment.
Although nutrient enrichment caused soil carbon gains in most dry, sandy regions, considerable absolute losses of soil carbon may occur in high-latitude regions that store the majority of the world's soil carbon.
Preface of phytobiome in nutrient recycling, biogeochemistry, and spatial dynamics
Abstract Nutrients are essential for plant growth. Thus, nutrient recycling is an integral part of soil science, nutrient chemistry, and sustainable agriculture. Biogeochemistry of nutrients is a
Dynamics and characteristics of biogenic silica and macro- and microelements in decomposing litter in the Min River estuary, southeast China
Tidal marshes are important recycling areas for biogenic silica (BSi) and macro- and microelements at the land–sea interface and are key locations for examining the decomposition process of wetland


How does drought stress influence the decomposition of plant litter with contrasting quality in a grassland ecosystem?
Background and aimsPlant litter quality and water availability both control decomposition. The interaction of both parameters was never studied. We used a grassland site, where litter of contrasting
Long-term litter decomposition controlled by manganese redox cycling
The results suggest that the litter-decomposing machinery at the authors' coniferous forest site depends on the ability of plants and microbes to supply, accumulate, and regenerate short-lived Mn3+ species in the litter layer, indicating that biogeochemical constraints on bioavailability, mobility, and reactivity of Mn in the plant–soil system may have a profound impact on litter decomposition rates.
Combined effects of multifactor climate change and land-use on decomposition in temperate grassland
Abstract Climate change is likely to alter decomposition rates through direct effects on soil biotic activity and indirect effects on litter quality with possible impacts on the global carbon budget
Climate change alters stoichiometry of phosphorus and nitrogen in a semiarid grassland.
It is indicated that soil moisture is important in controlling P supply from inorganic sources, causing reduced P relative to N availability during dry periods, and both wetter soil conditions under elevated CO(2) and drier conditions with warming can further alter N : P.
Early stage litter decomposition across biomes.
The results indicate that multiple drivers are affecting early stage litter mass loss with litter quality being dominant, and that long-term studies combined with experimental trials are needed to quantify the relative importance of the different drivers over time.
Microbial abundance and composition influence litter decomposition response to environmental change.
The results show that environmental changes can affect rates of ecosystem processes directly through abiotic changes and indirectly through microbial abundances and communities, and models of ecosystem response to global change may need to represent microbial biomass and community composition to make accurate predictions.
Understanding the dominant controls on litter decomposition
Summary 1. Litter decomposition is a biogeochemical process fundamental to element cycling within ecosystems, influencing plant productivity, species composition and carbon storage. 2. Climate has

Litter quality versus soil microbial community controls over decomposition: a quantitative analysis
The results indicate that the effects of changing microbial community composition on decomposition are likely to be smaller than the potential effects of climate change and/or litter quality changes in response to increasing atmospheric CO2 concentrations or atmospheric nutrient deposition.
