Factors controlling leaf litter breakdown in Amazonian streams
Our objective was to assess the relative importance of leaf litter quality, and the microbial and aquatic invertebrate communities involved in leaf litter breakdown in Amazonian streams. We test the hypothesis that leaf litter quality is the driving force of leaf breakdown rates, rather than the mic...

We incubated 3 g of Eucalyptus camaldulensis (EC), Baccharis platypoda, Symphonia globulifera, Mabea speciosa (MS), and Eperua duckeana (ED) leaves in five streams for 75, 56, 46, 26, 14, or 7 days.
