   Notes: Ecosystems: H =  heath (with or without birch trees),WW = wet woodland, R = ruderal, ME = meadow, A = alpine (above treeline), CF = coniferous forest, RB = riverbank, MI = mire. See Appendix C for further descriptions of ecosystems. Experimental treatments: 1 yr or 2 yr indicate incubation for one or two years. 5 mm = 5-mm mesh bags, TOP = incubation on the surface of the matrix litter. The last column indicates whether the litter bags contained 1.0 or 0.2 g of litter.
