“…In later phases of an invasion, post‐introduction evolution can contribute to an increase in a plant's impact and alter evolutionary responses of native species through a variety of processes including local adaptation, drift and phenotypic plasticity (Zenni, Dickie, et al, ). For a native species, such processes allow species to adapt in response to an invasion (Hulme & Le Roux, ). For a non‐native species, such processes contribute to local adaptation and range expansion (Colautti & Barrett, ).…”

1. Biological invasions are a major driver of ecosystem change but causes of variation in their environmental impacts over space and time remain poorly understood. Most approaches used to quantify the impacts of non-native species assume there are interactions among per capita (i.e. individual level) effects, species abundance and the area occupied by the species. However, studies rarely evaluate these factors and their interactions and often fail to recognize that the magnitude of impacts can be highly context dependent. Understanding what drives the context dependence of non-native species impacts can improve our understanding and predictions of ecosystem change and better inform options for mitigation.2. Conifers, especially pines, are among the most problematic non-native plant species globally. We use Pinaceae to illustrate how context dependence in biodiversity and environmental impacts of non-native plant species can be generated by at least four processes: nonlinear density effects; intraspecific variation in functional traits; shifts in impacts over time; and persistence of impacts as biological or ecosystem legacies following non-native species removal. Using this understanding, we develop a framework to better quantify interactions of impacts along environmental gradients (e.g. soil fertility, climate, ecosystem age).3. We demonstrate how impacts of non-native species can occur at both low and high density, and that failing to account for intraspecific variation in effect traits can lead to significant errors in the prediction of impacts. By incorporating context dependence in regard to density and functional traits, we can measure how the interaction of this context dependence will shift along environmental gradients. | 945Functional Ecology SAPSFORD et Al.

“…Plant invasion is recognized as a species that is established outside of its natural past or present distribution [5] and believed to cause damage to the environment and human health [6]. On whose introduction and/or invasion may alter ecosystem properties and community dynamics, even participating in feedback loops that affect climate change [7]. For example, Yuan et al [8] observed that exotic Spartina alterniflora invasion alters the ecosystem atmosphere exchange of CH 4 , N 2 O, and C sequestration in a coastal salt marsh in China.…”

The rapid expansion of Solidago canadensis and climate warming in southeastern China may interactively affect soil net nitrogen (N) mineralization, which may lead to plant invasion. A greenhouse simulated experiment was conducted with invasion, warming, and their interaction to investigate these changes' effects on soil net N mineralization in an ecological system. Our results indicated that the average rate of net mineralization, nitrification, and ammonification decreased with invasion, warming, and their interaction. The enzyme activities and pH showed more sensitivity in warming than invasion, and have a similar decreased trend with net N mineralization response to environmental changes, except sucrase. At the same time, enzyme and pH may play a key role in the process of net N mineralization from Pearson's correlation and redundancy analysis, especially for sucrase and urease. In addition, the lower produced of litter biomass by plants growing in pots was also an important reason for the decrease of net N mineralization rate. These results indicated that the significant decrease in substrate quality (N availability) by the increase in invasion and warming may cause the deterioration of species production in soil, which will have important consequences for soil ecology, N-cycles, and plant invasion.

“…Moreover, these plantations, with an average wood yield of 50 to 60 m 3 of Urograndis per hectare, need for higher amounts of agrochemicals, due to lower population diversity and lower adaptation to climate change (Kageyama & dos Santos, 2015). In short, here we highlight the threat on biodiversity that have been brought by alien species in headwaters and the changes that it can promote on native species (Hulme & Le Roux, 2016) which, in turn, impact the ecosystem services.…”
