NOT PEER-REVIEWED
"PeerJ Preprints" is a venue for early communication or feedback before peer review. Data may be preliminary.

Supplemental Information

Table S1

Summary of the results of independent one-way ANOVAs evaluating the effect of latitudinal origin (either population or temperature) on anatomical foliar traits and xanthophyll cycle pigment content of C. quitensis individuals sampled in the field. The net photosynthetic performance (measured as net photosynthesis rate) is shown under each thermal condition and population in common gardens and the ecophysiological responses to the simulated global warming expressed as the delta values between future and current individual values.

DOI: 10.7287/peerj.preprints.3069v1/supp-1

Table S2

Pair-wise a posteriori comparisons (HSD Tukey test’s) between the net photosynthetic response of each population under current (t0) and future conditions estimated during three simulated growing seasons (t1:t3). Bonferroni correction was applied to all P values due to multiple comparisons.

DOI: 10.7287/peerj.preprints.3069v1/supp-2

Table S3

Descriptive statistic of net photosynthesis measured (μmol CO2 m-2s-1) of each population under current (t0) and future conditions estimated during three simulated growing seasons (t1:t3). Mean, standard deviation (SD) and standard error (SE) are shown.
