Fig. 1 Heterogeneous water supply (A) and homogeneous water supply (B) of experiment. Patches are separated by white plastic wrap. In the heterogeneous water treatment, the dark grey cells stand for patches with high water supply, providing with 100 mL water to each patch once every three days; the white cells stand for patches with low water supply, providing with 50 mL water to each patch every three days. In the homogeneous treatment, each patch (grey cell) was provided with 76.3 mL every three days. The total water supplied in the heterogeneous treatment was same as that in the homogeneous treatment, i.e. 1450 mL every three days.
