Soil fauna modulates the effect of experimental drought on litter decomposition in forests invaded by an exotic pathogen

Litter decomposition is a fundamental process for nutrient cycling and C fluxes between terrestrial ecosystems and the atmosphere. Multiple factors such as environmental conditions, litter quality

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

A Warm Tea: The Role of Temperature and Hydroperiod on Litter Decomposition in Temporary Wetlands

Increasing global temperature and changes in the precipitation regime affect the global carbon cycle by altering the process of organic matter decomposition. Temporary aquatic systems are especially

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,

Impact of Tree Litter Identity, Litter Diversity and Habitat Quality on Litter Decomposition Rates in Tropical Moist Evergreen Forest.

Background: Attempts to restore degraded highlands by tree planting are common in East Africa. However, up till now, little attention has been given to effects of tree species choice on litter

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

Sedge replacement by grasses accelerates litter decomposition and decreases organic matter formation in alpine meadow soils

The dominance of sedges in Tibetan meadows is decreasing with the increasing abundance of grasses, mainly due to anthropogenic activities, nitrogen deposition, and climate warming. We investigated



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.

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.

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.

Interactions between leaf litter quality, particle size, and microbial community during the earliest stage of decay

With global change expected to alter aspects of the carbon (C) cycle, empirical data describing how microorganisms function in different environmental conditions are needed to increase predictive

Understanding the dominant controls on litter decomposition

Litter decomposition is a biogeochemical process fundamental to element cycling within ecosystems, influencing plant productivity, species composition and carbon storage. Climate has long been

Rates of litter decomposition in terrestrial ecosystems: global patterns and controlling factors

Aims We aim to construct a comprehensive global database of litter decomposition rate (k value) estimated by surface floor litterbags, and investigate the direct and indirect effects of impact

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.
