Leaf Litter Mixtures Alter Microbial Community Development: Mechanisms for Non-Additive Effects in Litter Decomposition
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 availability. Though relative abundance of decomposers may change due to mixing leaf litter, linking these shifts to the non-additive patterns o...
متن کاملSpecies diversity and chemical properties of litter influence non-additive effects of litter mixtures on soil carbon and nitrogen cycling
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. In this study, litters of Mongolian pine and three dominant understory species and soil were collected from a Mongolian pine plantation in Northeast Chi...
متن کاملDecomposition of diverse litter mixtures in streams.
In view of growing interest in understanding how biodiversity affects ecosystem functioning, we investigated effects of riparian plant diversity on litter decomposition in forest streams. Leaf litter from 10 deciduous tree species was collected during natural leaf fall at two locations (Massif Central in France and Carpathians in Romania) and exposed in the field in litter bags. There were 35 s...
متن کاملNon-additive effects of litter mixtures on net N mineralization in a southern New England forest
In this study, we developed simple, phenomenological models that enabled us to examine whether litter mixtures of differing quality increased, decreased, or had no effect on the rate of net N mineralization relative to a model that extrapolated the expected result assuming no interaction among litters of differing quality. We found that the presence of low Ž . quality litter e.g., litter with a...
متن کاملEffect of Litter Quality on Leaf-Litter Decomposition in the Context of Home-Field Advantage and Non-Additive Effects in Temperate Forests in China
Litter quality is often considered the main driver of rates of decomposition. Litter decomposes faster in its home environment than in any other environment, which is called the home-field advantage (HFA). However, evidence for this phenomenon has not been universal. In addition, litter mixtures of different species can induce a non-additive effect (NAE) on decomposition processes. However, the...
