From: An unexpected role for mixotrophs in the response of peatland carbon cycling to climate warming
Response of the bryosphere components (Sphagnum and associated mixotrophic testate amoebae and microalgae) to full light (PPFD of 600 μmol m−2 s−1) and dark treatments (no light) in microcosms (mean ± SE).
The effect of light conditions was tested on bryosphere photosynthetic capacity (Amax, bryo) (a) bryopshere maximum efficiency of PSII (Fv/Fm) (b) and bryosphere chlorophyll a+b content (c) microalgae (left) and mixotrophic testate amoeba (right) abundance (d) microalgae (left) and mixotrophic testate amoeba (right) biomass (e) microbial chlorophyll a+b content (f). White bars indicate light treatment and black bars dark treatment. Asterisks indicate significant differences between light and dark treatment. *P < 0.05; **P < 0.01; ***P < 0.001.
