“…Analogous to competition, high extent of plasticity is also assumed to be correlated to invasiveness. This theory was supported for different populations of one aquatic species (Hyldegaard & Brix ) and by Funk () when five invasive species were compared with five native. However, the theory was not supported when 20 native and 20 exotic invasive species were compared (Godoy et al .…”

“…One exception is the study by Poorter and Lambers () who showed that a more plastic genotype of Plantago major competed better than a less plastic one. Regarding invasive species, an invasive population of Ceratophyllum demersum was found to be more plastic than a non‐invasive one (Hyldegaard & Brix ), five invasive species were generally more plastic than five native species on Hawaii (Funk ), but there was no general difference in extent of plasticity between exotic invasive species and native species when 40 species in Spain were pairwise compared (Godoy et al . ).…”

31Plant species differ in their ability to transform available recourses to biomass and to respond 32 in a plastic way to environmental circumstances; we hypothesized that such differences 33 among four weed taxa of Papaver would explain differences in their competitive response. 34We first compared two populations each of Papaver rhoeas L., P. dubium L. ssp. dubium, P. 35 dubium L. ssp. lecoqii (Lamotte) Syme and P. argemone L., grown in greenhouse for six 36 weeks in a nutrient gradient combined with two light treatments to elucidate possible 37 differences in responses. As there were clear differences, a second experiment evaluated 38 whether these differences also meant differences in competitive response, during early 39 growth, when tested against two crops (wheat, rape). The assumption that competitive 40 response was linked to the ability to transform nutrient and light to biomass was not 41 supported: even though differences in extent of plasticity existed, the effect of competition 42 was similar for the taxa. Thus, higher plasticity and ability to transform available recourses to 43 biomass did not lead to stronger competitiveness for Papaver during early growth. 44

“…A large degree of phenotypic plasticity for resource capture has long been recognised as an important feature of submerged aquatic macrophytes (Going, Simpson & Even, ; Hyldgaard & Brix, ; Malheiro et al ., ). Phenotypic plasticity is defined as its capacity to produce morphologically or physiologically distinct phenotypes in response to different environmental influences (Bradshaw, ).…”

“…Phenotypic plasticity is considered as an important factor contributing to plant invasiveness, since rapid acclimation to the novel environment may be a precondition for establishment and subsequent competitive replacement of native species (Sultan, ; Hulme, ). Invasive plants have previously been shown to possess greater phenotypic plasticity than their native conspecific or congeneric relatives, allowing them to inhabit new areas with great success by obviating genetic adaptation through natural selection (Funk, ; Hyldgaard & Brix, ). Hence, understanding which abiotic factors, particularly growth‐limiting resources, can cause pronounced trait responses and limitations in exotic plants may help to predict the development of future invasions under global change.…”

Invasive submerged freshwater macrophytes are more plastic in their response to light intensity than to the availability of free CO₂ in air‐equilibrated water

1. The future increase in the atmospheric CO 2 concentration is likely to affect the growth and performance of submerged freshwater macrophytes because of higher concentrations of free CO 2 in the water at air equilibrium. We measured the plastic responses to free CO 2 and light for several traits of four invasive aquatic plants (Elodea canadensis, Egeria densa, Hydrilla verticillata and Ceratophyllum demersum) that use bicarbonate. 2. The plants were grown in standard culture media at either high (HiC, c. 50 lmol L À1 ) or low concentrations of free CO 2 (LowC, c. 19 lmol L À1 ) combined with high (HiL, c. 150 lmol m À2 s À1 ) or low (LowL, c. 21 lmol m À2 s À1 ) light intensity in a 2 9 2 factorial experiment. We compared the relative growth rate (RGR), several morphological traits, the photosynthetic response to light intensity and the bicarbonate uptake capacity of the four species. For every trait measured, we established plasticity indices for light and CO 2 availability. 3. Light intensity had a greater effect than CO 2 concentration on all species. The RGR of all four species was higher at high light intensity, and photosynthetic light responses acclimated to low light with a lower light compensation point, and with higher concentrations of photosynthetic pigments and quantum yield. The bicarbonate uptake capacity was generally highest at the high light intensity and high concentrations of free CO 2 . Plasticity indices for light intensity were consistently higher than for CO 2 availability in all four species. 4. As the growth and photosynthesis of the four invasive bicarbonate users were only slightly affected by the CO 2 availability in air-equilibrated water, the future rise in atmospheric CO 2 is unlikely to exacerbate their invasive behaviour and may even reduce their competitiveness against species unable to use bicarbonate, especially at limiting light.

The antagonistic effect of UV radiation on warming or nitrate enrichment depends on ecotypes of freshwater macroalgae (Charophytes)

Increases in ultraviolet radiation (UVR), a negative global change factor, affect aquatic primary producers. This effect is expected to be modulated by other global change factors, and to be different for populations adapted to different environments. A common garden experimental approach using freshwater green macroalgae, the cosmopolitan charophyte species Chara hispida and C. vulgaris, allowed us to test whether the beneficial increases in water temperature (T) and nitrate concentration (N) mitigate negative UVR effects. Also, whether these interactions would be not only species–specific but also according to the origin of the population; therefore, two populations of each species were used: one from a coastal wetland and the other from a mountain lake. Two factorial‐design experiments were performed: (i) the presence and absence of UVR × lower and higher T × four populations, and (ii) the presence and absence of UVR × lower and higher N × four populations. Response variables were: growth, morphometry, UVR‐protective compounds, photosynthetic pigments, and stoichiometric composition. There were consistent response patterns in the key variables that represent different organization levels. Our main results showed that both warming and, to a lesser extent, the increase in nutrients ameliorated the negative effects of UVR on the molecular processes involved in acclimation to UVR, and that such a mitigating effect depended on the different phenotypic plasticity of each species and each ecotype. The coastal populations, being from a more variable environment, were more resilient than the mountain populations, mainly because of changes in growth and morphology.
