Comparative summary of carbon isotope discrimination (Δ, bar chart), net CO2 assimilation (filled circles) and ETR (filled triangles) at optimal TWC for contrasting bryophyte life forms. Data summarized from figures 1–3, collated to show non-ventilated liverwort and hornwort thalli (hatched bars, Pn, Pellia endiviifolia; Pp, Pellia epiphylla; Mf, Megaceros fuegiensis), ventilated liverworts (blank bars, Cc, Conocephalum conicum; Lc, Lunularia cruciata; Mp, Marchantia polymorpha), and hornworts and algae with a CCM (grey bars, Mv, Megaceros vincentianus; Pc, Phaeoceros carolinianus; Co, Coleochaete orbicularis; Cr, Chlamydomonas reinhardtii).
