“…Therefore, it can be hypothesized that invasive exotic plants will have a greater positive response to elevated CO 2 conditions than their native counterparts, resulting in an increase in their competitive ability relative to slower growing species. Open top chamber (Dukes 2002;Hattenschwiler and Korner 2003), controlled environment glasshouse (Smith et al 1987), environmental controlled growth chamber (Sasek and Strain 1991;Ziska 2003; Baruch and Jackson 2005;Ziska et al 2005;McPeek and Wang 2007;Song et al 2009), and FACE (Smith et al 2000;Huxman and Smith 2001;Belote et al 2003;Nagel et al 2004) experiments that have manipulated CO 2 levels have provided evidence to support this hypothesis (but see Taylor and Potvin 1997;Dukes 2000;Bradford et al 2007 for exceptions).…”

We hypothesized that the greater competitive ability of invasive exotic plants relative to native plants would increase under elevated CO(2) because they typically have traits that confer the ability for fast growth when resources are not limiting and thus are likely to be more responsive to elevated CO(2). A series of competition experiments under ambient and elevated CO(2) glasshouse conditions were conducted to determine an index of relative competition intensity for 14 native-invasive exotic species-pairs. Traits including specific leaf area, leaf mass ratio, leaf area ratio, relative growth rate, net assimilation rate and root weight ratio were measured. Competitive rankings within species-pairs were not affected by CO(2) concentration: invasive exotic species were more competitive in 9 of the 14 species-pairs and native species were more competitive in the remaining 5 species-pairs, regardless of CO(2) concentration. However, there was a significant interaction between plant type and CO(2) treatment due to reduced competitive response of native species under elevated compared with ambient CO(2) conditions. Native species had significantly lower specific leaf area and leaf area ratio under elevated compared with ambient CO(2). We also compared traits of more-competitive with less-competitive species, regardless of plant type, under both CO(2) treatments. More-competitive species had smaller leaf weight ratio and leaf area ratio, and larger relative growth rate and net assimilation rate under both ambient and elevated CO(2) conditions. These results suggest that growth and allocation traits can be useful predictors of the outcome of competitive interactions under both ambient and elevated CO(2) conditions. Under predicted future atmospheric CO(2) conditions, competitive rankings among species may not change substantially, but the relative success of invasive exotic species may be increased. Thus, under future atmospheric CO(2) conditions, the ecological and economic impact of some invasive exotic plants may be even greater than under current conditions.

“…For example, Spartina alterniflora was found to have a competitive advantage over native plant species ). Other studies illustrated significant differences in the response of native and invasive plants (Mikania micrantha, Wedelia trilobata, Ipomoea cairica) to elevated concentrations of CO 2 and discussed these results in terms of a future success of invasive species in the face of ongoing increases in atmospheric CO 2 concentrations (Song et al 2009, Song et al 2010. found that increased temperatures enhance the aboveground biomass in Ipomoea cairica as well as the phytotoxicity of aqueous leachates from fresh leaves of this introduced liana.…”

“…For example, Song et al (2009) found that the increase in photosynthetic rate due to elevated CO 2 concentrations was significantly higher in non-native than in native species. In a study on the Yangtze River system, Jiang et al Studies on the genetic variation or diversity of non-native plants revealed a very low genetic diversity in most clonal invasive plants such as Alternanthera philoxeroides and Eichhornia crassipes (Mart.)…”

Plant invasions in China: an emerging hot topic in invasion science

China has shown a rapid economic development in recent decades, and several drivers of this change are known to enhance biological invasions, a major cause of biodiversity loss. Here we review the current state of research on plant invasions in China by analyzing papers referenced in the ISI Web of Knowledge. Since 2001, the number of papers has increased exponentially, indicating that plant invasions in China are an emerging hot topic in invasion science. The analyzed papers cover a broad range of methodological approaches and research topics. While more that 250 invasive plant species with negative impacts have been reported from China, only a few species have been considered in more than a handful of papers (in order of decreasing number of references: Spartina alterniflora, Ageratina adenophora, Mikania micrantha, Alternanthera philoxeroides, Solidago canadensis, Eichhornia crassipes). Yet this selection might rather reflect the location of research teams than the most invasive plant species in China. Considering the previous achievements in China found in our analysis research in plant invasions could be expanded by (1) compiling comprehensive lists of non-native plant species at the provincial and national scales and to include species that are native to one part of China but non-native to others in these lists; (2) strengthening pathways studies (primary introduction to the country, secondary releases within the country) to enhance prevention and management; and (3) assessing impacts of invasive species at different spatial scales (habitats, regions) and in relation to conservation resources.

“…Fast-growing species require higher capture of nutrients and have a stronger carbon drain, and therefore respond more intensively to an increase in [CO 2 ] (Poorter 1993;Poorter & Navas 2003). The increase in [CO 2 ] is likely to promote the dominance of invasive species (Smith et al 2000;Polley et al 2002;Weltzin et al 2003), which can be stimulated to increase growth and leaf area as well as biomass of leaves, stems and roots (Ziska & George 2004;Song et al 2009). Several authors have postulated that climate change will have imbalanced effects among native and invasive plants .…”

“…These characteristics, associated with a high phenotypic variability, may enhance the ability of B. dracunculifolia to behave as an invasive species (Negreiros et al 2014). The great plasticity shown by invasive species allow them to adjust the allocation of biomass (Song et al 2009) or maximize the production of seeds, favoring the colonization of habitats after disturbances (Chew & Bonser 2009). In a future scenario of changes in resource availability by increased [CO 2 ], species with large plastic capacity may have greater success in establishment, by changing physiological or morphological traits to maintain the balance of resource acquisition.…”

The increase in atmospheric CO 2 concentration predicted to the end of this century may cause several alterations on plant species development, which shall result in changes in the structure and function of plant communities. The present work aimed to investigate the effects of the increase in atmospheric CO 2 concentration on the development of Baccharis dracunculifolia, a key pioneer Neotropical shrub. Seedlings of B. dracunculifolia were exposed to 720 ppm of CO 2 as well as to ambient concentration of CO 2 (approximately 360 ppm) during 120 days in open top chambers. Growth and dry biomass accumulation were higher under elevated CO 2 concentrations. As a response to CO 2 enrichment, there was an increase of 134% in total dry mass, 208% in root dry mass and 152% in stem dry mass. The shrubby habit of B. dracunculifolia and the larger number of meristems produced under high CO 2 promoted the increase in 137% in the number of branches. The present study contributes to the knowledge about how pioneer tropical plants may respond to increased atmospheric [CO 2 ] in environments with low nutrient limitation.
