Fig. 2 : Responses of leaf resource characteristics (a-c), invertebrate community structure (d-f) and ecosystem functions (g-i) to flow permanence (FP), upstream proportion of perennial reaches (upstream connectivity: UC%) and upstream distance to the source (DS). Response variables include: leaf stock mass (a), carbon to nitrogen leaf contents (C/N; b-c), shredder abundances (d,f), invertebrate richness (e) and coarse and fine mesh leaf bag decomposition rates (Coarse K and Fine K, g-i). Full and dotted lines indicate significant and non-significant relationships, respectively. Responses were grouped by seasons, flow regime and locations to illustrate interactions. Regressions in (g) were fitted with a quadratic polynomial function.
