Photochemical efficiency of photosystem II, photon yield of O2 evolution, photosynthetic capacity, and carotenoid composition during the midday depression of net CO2 uptake in Arbutus unedo growing in Portugal

TL;DR: During the “midday depression” of net CO2 exchange in the mediterranean sclerophyllous shrub Arbutus unedo, examined in the field in Portugal during August of 1987, several parameters indicative of photosynthetic competence were strongly and reversibly affected.

Photosynthesis and water relations of lichen soil crusts: field measurements in the coastal fog zone of the Namib Desert
TL;DR: Although the coastal fog zone of the Namib Desert has negligible rainfall, large parts may be covered by soil-crust lichens with chlorophyll contents and photosynthetic rates on an area basis, almost equal to the leaves of typical higher plants.

Effect of high light on the efficiency of photochemical energy conversion in a variety of lichen species with green and blue-green phycobionts.
TL;DR: Green algalLichens were able to recover from exposure to excessive PFDs when thalli were in either the hydrated or desiccated state during such an exposure, whereas in blue-green algal lichens the decrease in photochemical efficiency was reversible in thalli illuminated in the desiccate state but rather sustained subsequent to illumination of thalli in the Hydrated state.

Water relations and CO2 exchange of the terrestrial lichen Teloschistes capensis in the Namib fog desert: Measurements during two seasons in the field and under controlled conditions
TL;DR: In both seasons, nocturnal hydration, by fog and/or dew, activated dark respiration of the lichens which was followed, after sunrise, by a short period of positive net photosynthesis (NP) that continued until metabolic inactivation occurred from desiccation, which reduced NP in lab and field experiments and caused an extended period of recovery.

Limitations due to water stress on leaf net photosynthesis of Quercus coccifera in the Portuguese evergreen scrub
TL;DR: During the late stages of drought in September, severe water stress led to reduction in mesophyll photosynthetic capacity and further reduction in leaf conductance, correlated with decrease in the daily minimum leaf water potential to greater negative values than-30 bar.
