“…The results of these experiments with large sets of populations originating from a wide geographical range across Europe and Israel, have confirmed the existence of a large phenotypic variability in both plant species within their native ranges of occurrence (Dykyjová, 1978a; Edwards, 1996; Clevering, 1999; Clevering et al ., 2001; Bastlová & Květ, 2002; Olsson & Ågren, 2002; Bastlová et al ., 2003). In particular, they have reinforced our previous results indicating a relationship between the latitude of the original geographical location of the plants on the one hand and their growth dynamics and biomass allocation patterns on the other (Bastlová et al ., 2003). Decreasing latitude was associated with an increase in the overall size of above‐ground plant parts of L. salicaria (including both shoot height and total above‐ground dry weight) and with an increase in the total shoot height of P. australis .…”

“…Our study, and some previous ones (Edwards et al ., 1998; Bastlová et al ., 2003), indicate, however, that even within the species’ native range, i.e. in conditions where herbivores are naturally present, L. salicaria genotypes exist that are similar to invasive ones in vigorous vegetative growth and reduced allocation to reproductive structures.…”

“…Previous studies of L. salicaria have shown that plants originating from a small geographical area (e.g. country), had comparable plant growth characteristics if the effect of nutrient supply was eliminated by cultivating the plants under identical experimental conditions (Bastlová & Květ, 2003; Bastlová et al ., 2003). Consequently, the highest proportion of variability in plant morphological characteristics within the native range was attributed to latitude of the original geographical location.…”

“…In many cases, however, the variability of plant growth characteristics was found to be very high both within the native and the invasive sets of the populations studied. More detailed studies, involving plants originating from broader geographical areas, showed latitudinal differentiation in life history, phenology and biomass allocation pattern in native genotypes across the European geographical gradient (Olsson & Ågren, 2002; Bastlová et al ., 2003). Most of the plant growth characteristics indicated clinal variation and their values significantly increased with decreasing latitude of the sites from which the studied plants originated (Bastlová et al ., 2003).…”

AimThe response of L. salicaria and P. australis plants originating from a broad latitudinal gradient to mineral nutrient and water supply was studied. We suggest implications for mechanisms possibly underlying the invasiveness of these two plant species.Location A common garden tub experiment was carried out at T r ebo ˜ , Czech Republic (49 ° N 14 ° 47 ′ E, altitude 433 m). MethodsPlants of 30 L. salicaria and 6 P. australis populations originating from a wide geographical area in Europe and in Israel (60 °− 32 ° N latitude, 6 ° W − 20 ° E longitude) were cultivated for one growing season at two water levels and three ( L. salicaria ) or two ( P. australis ) nutrient doses, respectively. At the end of cultivation, basic morphological and growth characteristics were recorded. ResultsThe latitude of the original geographical location was the most significant factor, affecting both the phenology and most of the plant morphological and growth characteristics measured in both plant species, with the characteristics related to plant size being negatively correlated with latitude. The effect of nutrient dose was very strong in both species, while the effect of water level was more pronounced in P. australis than in L. salicaria . Main conclusionsThe results confirmed the existence of a large phenotypic variability in both plant species within their native ranges of occurrence. In both plant species, the latitudinal variation in plant morphological and growth characteristics most probably indicates the differentiation of genotypes adapted to local geographical conditions. The plants of both species originating from all geographical locations tested responded to the respective nutrient treatments in a similar manner. Exceptions were found in growth characteristics related to reproduction in L. salicaria , indicating that better nutrient supply could enhance the reproductive ability of certain genotypes. Based on the results obtained, we suggest implications for mechanisms possibly underlying the invasiveness of the plant species studied.

“…, 1987). Latitudinal clines in flowering time and associated life‐history traits have been demonstrated in two separate regions of the species’ native range (Olsson & Ågren, 2002; Bastlová et al. , 2004, 2006; Olsson, 2004), but nothing is known of geographic variation in life history among introduced populations.…”

Range expansion during biological invasion requires that invaders adapt to geographical variation in climate, which should yield latitudinal clines in reproductive phenology. We investigated geographic variation in life history among 25 introduced populations of Lythrum salicaria, a widespread European invader of North American wetlands. We detected a strong latitudinal cline in initiation of flowering and size at flowering, which paralleled that reported among native populations. Plants from higher latitudes flowered earlier and at a smaller size than those from lower latitudes, even when raised in a uniform glasshouse. Early flowering was associated with greatly reduced reproductive output, but this was not associated with latitudinal variation in abundance, and probably did not result from a genetic correlation between time to and size at flowering. As introduction to North America c. 200 years ago, L. salicaria has re‐established latitudinal clines in life history, probably as an evolutionary response to climatic selection.

It is important to investigate the molecular causes of the variation in ecologically important traits to fully understand phenotypic responses to climate change. In the Mississippi River Delta, two distinct, sympatric invasive lineages of common reed (Phragmites australis) are known to differ in several ecophysiological characteristics and are expected to become more salt resistant due to increasing atmospheric CO2 and temperature. We investigated whether different patterns of gene expression can explain their ecophysiological differences and increased vigor under future climatic conditions. We compared the transcript abundance of photosynthetic genes of the Calvin cycle (Rubisco small subunit, RbcS; Phosphoglycerate kinase, PGK; Phosphoribulokinase, PRK), genes related with salt transport (Na+/H+ antiporter, PhaNHA) and oxidative stress response genes (Manganese Superoxide dismutase, MnSOD; Glutathione peroxidase, GPX), and the total aboveground biomass production between two genotypes representing the two lineages. The two genotypes (Delta-type, Mediterranean lineage, and EU-type, Eurasian lineage) were grown under an ambient and a future climate scenario with simultaneously elevated CO2 and temperature, and under two different soil salinities (0‰ or 20‰). We found neither differences in the aboveground biomass production nor the transcript abundances of the two genotypes, but soil salinity significantly affected all the investigated parameters, often interacting with the climatic conditions. At 20‰ salinity, most genes were higher expressed in the future than in the ambient climatic conditions. Higher transcription of the genes suggests higher abundance of the protein they code for, and consequently increased photosynthate production, improved stress responses, and salt exclusion. Therefore, the higher expression of these genes most likely contributed to the significantly ameliorated salinity impact on the aboveground biomass production of both P. australis genotypes under elevated temperature and CO2. Although transcript abundances did not explain differences between the lineages, they correlated with the increased vigor of both lineages under anticipated future climatic conditions.
