Caption
Soil extracellular enzyme activities in the surface (0-5 cm) and subsurface (5-20 cm) layers of alpine meadow (A-F) and swamp meadow (G-L) under different warming treatments.CK: control treatment; 3-yr W: 3-year warming treatment; 6-yr W: 6-year warming treatment. Yellow, blue, and red dots indicate control, lower, and higher warming treatments, respectively, and while grey dots represent raw data collected before the warming experiment started. Different lowercase letters indicate significant differences (p < 0.05) between treatments at the same depth; non-significant differences are not marked. The straight lines indicate significant relationships (p < 0.05) between soil enzyme activities and warming duration under lower (blue line) and higher (red line) warming.
