Terrestrial plant litter is important in sustaining stream food webs in forested headwaters. Leaf litter quality
often decreases when native species are replaced by introduced species, and a lower quality of leaf litter
inputs may alter litter decomposition at sites afforested with non-native species. However, since detritivore
composition and resource use plasticity may depend on the prevalent litter inputs, the extent of the alteration
in decomposition can vary between streams. We tested 2 hypotheses using 2 native and 3 introduced
species of tree differing in quality in 4 Iberian regions with contrasting vegetational traits: 1) decomposition
rates of all plant species would be higher in regions where streams normally receive litter inputs of lower
rather than higher quality; 2) a higher resource-use plasticity of detritivores in regions vegetated with plants
of lower litter quality will cause a greater evenness in decomposition rates among plant species compared to
regions ...
