Table 3.

Differences in light compensation point (PPFD_c), maximum quantum yield of PSII (F_v/F_m), and quantum yield of PSII (Φ_PSII) between (a) habitat, (b) species (in the order of increasing PPCD_c), and (c) month. Post hoc contrast results from the linear-mixed-effects models. Undrained state, Sphagnum girgensohnii and July are the baselines, two of which are kept constant while the predictor variable in question changes. P-values indicate significant differences from undrained, S. girgensohnii, and July, respectively. Average ± SE, n = number of measured moss samples.
