ppl1662-sup-0001-Figures1.pdfPDF document93K Fig. S1. Above ground dry weight and relative dry weight of C3 and C4 grasses throughout the 2010 growing season.
ppl1662-sup-0002-Figures2.pdfPDF document79K Fig. S2. Fv/Fm of C3 and C4 grasses throughout the 2010 growing season. Each point represents daily averages of four to nine measurement time-points, each composed of five to seven leaf replicates (±se). In most cases error bars are smaller than the symbol and therefore not visible.
ppl1662-sup-0003-Figures3.pdfPDF document94K Fig. S3. Daily responses of NPQ and ΦPSII of C3 and C4 grasses and corresponding environmental conditions, for two representative days of the 2010 growing season. Measurement time-points represent an average of five to seven leaf samples (±se).
ppl1662-sup-0004-TableS1.pdfPDF document79K Table S1. Variance explained by nested random factors, day of year and time of day, within modeled responses of ΦPSII, NPQ and EPS. Percentages may not add up to 100% due to rounding.
ppl1662-sup-0005-TableS2.pdfPDF document74K Table S2. Temperature measurements from the Grand Lake Meadows and environmental conditions for Fredericton during the 2010 growing season. The 2010 climate at this site was within the cooler range of the defined temperature limits of C4 photosynthesis (Long 1999, Sage et al. 1999b).
