TL;DR: Low mesophyll conductance to CO2 was the main cause for low photosynthesis in ferns and fern allies, which, in turn, was associated with thick cell walls and reduced chloroplast distribution towards intercellular mesophyLL air spaces.

TL;DR: This study focused on the photosynthetic responses of Polylepis species and how they are able to cope with such a challenging environment as low temperatures, high solar radiation and water scarcity.

TL;DR: It is proposed that niche differentiation between sprouts and saplings extends the regeneration niche to suboptimal conditions for sexual recruitment and contributes toward explaining the high colonization ability of E. cordifolia in this kind of forest, whose composition is strongly driven by gap dynamics.

TL;DR: It is suggested that the acclimation of the photosynthetic capacity among current leaf cohorts represents a well-tuned mechanism helping E. cordifolia seedlings to face a single stress like shade or drought stress, but is insufficient to cope with simultaneous stresses.

TL;DR: The physiological differences between sexual and vegetative recruits satisfactorily explain the ecological niche of E. cordifolia, with saplings restricted to more closed and humid sites.
