Decomposition rates (mean ± SE) of Alnus incana (white bars) and Betula pendula (grey bars) expressed as rates per degree-day, in autumn and spring, and pools and riffles. Table 1. Results of the mixed-effect model containing the response variable leaf decomposition rates (calculated as per degree-day) and the predictors season, habitat, and leaf species, and its 2- and 3-way interaction terms.

jane12142-sup-0004-AppendixS4.docWord document137KAppendix S4. Canonical correspondence analysis (CCA) of the detritivore species in pools and riffles, and in autumn and spring. Habitats and seasons are differentiated in this analysis using the continuous variables mean water flow velocity (m s−1; lower in pools and higher in riffles) and mean water temperature (°C; lower in autumn and higher in spring).
