1) Figure 5: PPFD response curves of relative electron flow rate (REFR), NPQ and l-qP,from chlorophyll-fluorescence measurements for two representative species. Plagiomnium undulatum is a shade-loving species, while Racomitrium lanuginosum is a species of sun-exposed habitats. Note the different x-axis scales of the curves, and the varying y-axis scales of the REFR graphs. The y-axis scales for NPQ and 1-qP are the same throughout.
