Resource–consumer diversity: testing the effects of leaf litter species diversity on stream macroinvertebrate communities
1. Understanding relationships between resource and consumer diversity is essential to predicting how changes in resource diversity might affect several trophic levels and overall ecosystem functioning. 2. We tested for the effects of leaf litter species diversity (i.e. litter mixing) on litter mass remaining and macroinvertebrate communities (taxon diversity, abundance and biomass) during brea...
متن کاملTree species richness affects litter production and decomposition rates in a tropical biodiversity experiment
We report data on leaf 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. A total of 24 plots (2025 m) were established in 2001 using six native tree species, with 1-, 3-, and 6-species mixtures. We estimated litter production during t...
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 کاملNo evidence for leaf-trait dissimilarity effects on litter decomposition, fungal decomposers, and nutrient dynamics.
Biodiversity and ecosystem-functioning theory suggest that litter mixtures composed of dissimilar leaf species can enhance decomposition due to species trait complementarity. Here we created a continuous gradient of litter chemistry trait variability within species mixtures to assess effects of litter dissimilarity on three related processes in a natural stream: litter decomposition, fungal bio...
