From: Photosynthetic parameters of a sedge-grass marsh as a big-leaf: effect of plant species composition

Photosynthesis–irradiance (PPFD) relationship (PN/I) of the five plant species and weighted PN/I relationship for a theoretical “ecosystem big-leaf” (black line) modelled by non-rectangular hyperbolas. Grey areas represents standard errors of average PN/I relationships.
