Abstract Background Invasive species can threaten native diversity and alter ecosystem processes while interacting with other components of global environmental change. Invasive plants are becoming increasingly problematic and this can be stimulated by changes in the environment. However, existing studies have primarily investigated the effects of environmental change on a specific stage of plant invasion rather than the continuous invasion process. Methods A space-for-time substitution experiment was performed to investigate how warming and nitrogen deposition affects the invasion process of a plant. Specifically, different ratios of invasive Solidago canadensis L. to native Artemisia argyi Levl. et Van were employed as a proxy to represent successive levels of invasion. A total of seven treatments were applied in the experiment: ambient (CK), N addition (+ 5, + 12 g m−2 year−1), warming (+ 1.15, + 1.86 °C) and their interaction (5 g N m−2 year−1 + 1.15 °C, 12 g N m−2 year−1 + 1.86 °C). The growth performance and competitiveness of S. canadensis were investigated. Results The competitiveness of Solidago canadensis decreased linearly with its invasion degree (p |
