From: Warming and elevated nitrogen deposition accelerate the invasion process of Solidago canadensis L.
Responses of growth and competitiveness of Solidago canadensis to environmental change. A total of seven environmental treatments were imposed: CK (control), N5 (N addition 5 g m-2 yr-1), N12 (N addition 12 g m-2 yr-1), T1 (temperature increase of 1.15 °C), T1N5 (combined 1.15 °C temperature increase and N addition of 5 g m-2 yr-1), T2 (temperature increase of 1.86 °C) and T2N12 (combined 1.86 °C temperature increase and N addition of 12 g m-2 yr-1). The sample size for each group in each boxplot is 60
