Limnologica, 2016 Nutrient enrichment and changes in riparian tree species composition affect many streams worldwide but their combined effects on decomposers and litter decomposition have been rarely assessed. In this study we assessed the effects of experimental nitrogen (N) enrichment of a small forest stream on the decomposition of three leaf litter species ...

Non-Additive effects on decomposition from mixing litter of the invasive Mikania micrantha H.B.K. with native plants. [PDF]
PLoS ONE, 2013 A common hypothesis to explain the effect of litter mixing is based on the difference in litter N content between mixed species. Although many studies have shown that litter of invasive non-native plants typically has higher N content than that of native

Pulse frequency and soil‐litter mixing alter the control of cumulative precipitation over litter decomposition [PDF]
Ecology, 2017 AbstractMacroclimate has traditionally been considered the predominant driver of litter decomposition. However, in drylands, cumulative monthly or annual precipitation typically fails to predict decomposition. In these systems, the windows of opportunity for decomposer activity may rather depend on the precipitation frequency and local factors ...

Leaf litter mixtures alter microbial community development: mechanisms for non-additive effects in litter decomposition. [PDF]
PLoS ONE, 2013 To what extent microbial community composition can explain variability in ecosystem processes remains an open question in ecology. Microbial decomposer communities can change during litter decomposition due to biotic interactions and shifting substrate ...

Species diversity and chemical properties of litter influence non-additive effects of litter mixtures on soil carbon and nitrogen cycling. [PDF]
PLoS ONE, 2017 Decomposition of litter mixtures generally cannot be predicted from the component species incubated in isolation. Therefore, such non-additive effects of litter mixing on soil C and N dynamics remain poorly understood in terrestrial ecosystems.

Litter decomposition in peatlands is promoted by mixed plants [PDF]
Journal of Soils and Sediments, 2017 Purpose: The carbon sink function of peatlands is primarily driven by a higher production than decomposition of the litter Sphagnum mosses. The observed increase of vascular plants in peatlands could alter the decomposition rate and the carbon (C) cycle through a litter mixing effect, which is still poorly studied.

Ecology and EvolutionThe effect of mixing litter on decomposition has received considerable attention in terrestrial and aquatic (but rarely in both) ecosystems, with a striking lack of consensus in the obtained results.

Effects of litter mixing on litter decomposition and soil properties along simulated invasion gradients of non-native trees [PDF]
Plant and Soil, 2019 Aims Plant invasions generally lead to mixtures betweennative and non-native litter. We assess the interactionsbetween leaf litters from two invasive non-native trees(Robinia pseudoacia or Ailanthus altissima) and the nativePopulus alba on litter decomposition, nutrient releaseand soil properties along two gradients of invasion.Methods Microcosms with ...

Guangxi ZhiwuLitter is an important part of forest productivity, and its productivity and stoichiometric ratio(high N and low C:N, C:P and N:P, which facilitate litter decomposition)are vital in regulating soil carbon dynamics through decomposition rate modulation ...

Mixing effects of understory plant litter on decomposition and nutrient release of tree litter in two plantations in Northeast China. [PDF]
PLoS ONE, 2013 Understory vegetation plays a crucial role in carbon and nutrient cycling in forest ecosystems; however, it is not clear how understory species affect tree litter decomposition and nutrient dynamics.
