“…Our previous study showed that the phenotypic plasticity of S . canadensis is high in response to temperature and water availability [22]. In the present study, we observed strong plasticity of the proline content, intermediate plasticity of the net photosynthetic rate, stomatal conductance and relative chlorophyll content, and relatively weaker plasticity of the transpiration rate and the activity of peroxidase.…”

“…Based on growth chamber and greenhouse experiments, we determined that the phenotypic plasticity of S . canadensis may have evolved rapidly in regions with different climatic conditions and might have contributed to the spread of this invasive species [22]. However, we also found that individual plasiticty, not local adaptation, plays an important role in the response of S .…”

“…Furthermore, local adaptation has been well verified as a major mechanism enhancing invasiveness [13], which helps invasive plants successfully adapt to novel heterogeneous environments [7, 9]. Alternatively, phenotypic plasticity, the ability of a single genotype to produce different phenotypes in response to environmental variation [14–16], also contributes to the success of an invasive plant species by allowing increased fitness across a range of habitats [3, 17–22] and plays an important role in successful establishment under novel conditions [19, 23]. A central issue in invasion ecology is determining the importance of phenotypic plasticity and local adaptation in the adaption of invasive plant to novel heterogeneous environments across its distribution.…”

Local adaptation is an important mechanism underlying the adaptation of plants to environmental heterogeneity, and the toxicity of salt results in strong selection pressure on salt tolerance in plants and different ecotypes. Solidago canadensis, which is invasive in China, has spread widely and has recently colonized alkali sandy loams with a significant salt content. A common greenhouse experiment was conducted to test the role of local adaptation in the successful invasion of S. canadensis into salty habitats. Salt treatment significantly decreased the growth of S. canadensis, including rates of increase in the number of leaves and plant height; the root, shoot, and total biomass. Furthermore, salt stress significantly reduced the net photosynthetic rate, stomatal conductance, transpiration rate and relative chlorophyll content but significantly increased peroxidase activity and the proline content of S. canadensis and the root/shoot ratio. Two-way analysis of variance showed that salt treatment had a significant effect on the physiological traits of S. canadensis, except for the intercellular CO2 concentration, whereas the population and the salt × population interaction had no significant effect on any physiological traits. Most of the variation in plasticity existed within and not among populations, excep for the root/shoot ratio. S. canadensis populations from soil with moderate/high salt levels grew similarly to S. canadensis populations from soils with low salt levels. No significant correlation between salt tolerance indices and soil salinity levels was observed. The plasticity of the proline content, intercellular CO2 concentration and chlorophyll content had significant correlations with the salt tolerance index. These findings indicate a lack of evidence for local adaption in the existing populations of invasive S. canadensis in China; instead, plasticity might be more important than local adaptation in influencing the physiological traits and salt tolerance ability across the S. canadensis distribution.

“…The plasticity of S. canadensis appears to have a significant influence on its invasive success within a new range in China. It is presumed that the rapid spread of non‐native S. canadensis is related to the rapidly evolving phenotypic plasticity in regions with different climatic conditions (Li, Du, Guan, Yu, & van Kleunen, ). The results of other studies have proved that plasticity in S. canadensis plays a central role in shade adaptation (Du, Liu, Yan, Li, & Li, ) and salt tolerance (Li, Liu, Yan, & Du, ).…”

High phenotypic plasticity contributes to invasiveness of alien species. Goldenrods of American origin (Solidago canadensis, S. gigantea and Euthamia graminifolia) have successfully invaded Europe, and this success can be related to their high phenotypic plasticity. The aim of our study was to test the hypothesis of higher phenotypic plasticity of invasive goldenrods by comparing them with native taxa: closely related Solidago virgaurea and similar ecologically, invasive in other regions Tanacetum vulgare. The species studied were grown in a common garden on three different substrates with different fertilizers. After 3 years, the height and number of ramets, biomass production and allocation, phenology and nitrate reductase activity (NRA) were measured. The highest level of phenotypic plasticity was exhibited by the competitively weak native species S. virgaurea. The invasive species produced relatively high biomass and exhibited a moderate level of phenotypic plasticity. Variability in the studied traits did not always correlate with differences in substrates. The invasion success of non‐native goldenrods is not caused by their having a higher phenotypic plasticity than native species. Rather, the non‐natives should be considered as “Jack of all traits, and master of some”.

“…The low viability of the SW population specially at the 18L:6D photoperiod may arise from photoperiod‐induced disruption of the circadian system due to the higher plasticity in this northern population (Liu & Zhao, ). Clinal variation in phenotypic plasticity is observed in many organisms, and this might be explained by higher fluctuations in environmental conditions at northern latitudes (Li, Du, Guan, Yu, & van Kleunen, ; Mathur & Schmidt, ; Molina‐Montenegro & Naya, ). A reduction of viability in response to day length has been observed in D. melanogaster , where a long photoperiod reduced survival (Vaiserman et al, ).…”

Introduction Organisms use environmental cues to match their phenotype with the future availability of resources and environmental conditions. Changes in the magnitude and frequency of environmental cues such as photoperiod and temperature along latitudes can be used by organisms to predict seasonal changes. While the role of temperature variation on the induction of plastic and seasonal responses is well established, the importance of photoperiod for predicting seasonal changes is less explored. Materials and methods Here we studied changes in life‐history and thermal stress resistance traits in Drosophila subobscura in response to variation in photoperiod (6:18, 12:12 and 18:6 light:dark cycles) mimicking seasonal variations in day length. The populations of D. subobscura were collected from five locations along a latitudinal gradient (from North Africa and Europe). These populations were exposed to different photoperiods for two generations, whereafter egg‐to‐adult viability, productivity, dry body weight, thermal tolerance, and starvation resistance were assessed. Results We found strong effects of photoperiod, origin of populations, and their interactions on life‐history and stress resistance traits. Thermal resistance varied between the populations and the effect of photoperiod depended on the trait and the method applied for the assessment of thermal resistance. Perspectives Our results show a strong effect of the origin of population and photoperiod on a range of fitness‐related traits and provide evidence for local adaptation to environmental cues (photoperiod by population interaction). The findings emphasize an important and often neglected role of photoperiod in studies on thermal resistance and suggest that cues induced by photoperiod may provide some buffer enabling populations to cope with a more variable and unpredictable future climate.
