The potential for nighttime CO2 uptake and/or increases in tissue acidity characteristic of crassulacean acid metabolism (CAM) was investigated, to varying degrees, in 12 species of Vittariaceae as well as in seven species in four other families of tropical epiphytic ferns. Evidence of CAM (actually CAM cycling, i.e., diel changes in tissue acidity without nighttime atmospheric CO2 uptake), though highly variable, was found in two species of Vittariaceae. The ecophysiological significance of… 
Low-level CAM photosynthesis in a succulent-leaved member of the Urticaceae, Pilea peperomioides.
TLDR
This is the first report of CAM in the family Urticaceae and nocturnal increases in titratable acidity in both leaf laminas and petioles were observed in all plants exposed to wet-dry-wet cycles, providing unequivocal evidence of CAM activity.
EVOLUTIONARY ASPECTS OF CRASSULACEAN ACID METABOLISM
TLDR
CAM is widely distributed among botanical families, its origin is believed to be polyphyletic; however, the evolutionary mechanisms which allowed reappearance of this complex metabolism are not yet understood.
The photosynthetic pathway of the roots of twelve epiphytic orchids with CAM leaves
TLDR
The photosynthetic pathway of the roots was investigated in twelve taxa of epiphytic orchids having CAM leaves, and the a/b ratios indicate that the organs, especially the roots, are likely shade-adapted.
Sun/shade adaptations of the photosynthetic apparatus of Hoya carnosa, an epiphytic CAM vine, in a subtropical rain forest in northeastern Taiwan
TLDR
Results of this investigation reveal that H. carnosa in this subtropical rain forest in Taiwan exhibits adaptations to both high and low light levels, which should prove adaptive for an epiphytic vine with leaves on the same individual exposed to a wide range of exposure and shade in the host tree canopy.
Canopy CO2 concentrations and Crassulacean acid metabolism in Hoya carnosa in a subtropical rain forest in Taiwan: consideration of CO2 availability and the evolution of CAM in epiphytes
TLDR
It is found that host-respired CO2 does not contribute substantially to the carbon budget of this epiphytic CAM plant, and this finding does not support the hypothesis that CAM may have evolved in tropicalEpiphytes in response to diel changes in the CO2 concentrations within the host tree canopy.
Water stress and abscisic acid treatments induce the CAM pathway in the epiphytic fern Vittaria lineata (L.) Smith
TLDR
Findings suggest that V. lineata could change its mode of carbon fixation from C3 to the CAM pathway in response to drought, and the concentrations of carotenoids were stable.
Water stress and abscisic acid treatments induce the CAM pathway in the epiphytic fern Vittaria lineata ( L . )
Among various epiphytic ferns found in the Brazilian Atlantic Forest, we studied Vittaria lineata (L.) Smith (Polypodiopsida, Pteridaceae). Anatomical characterization of the leaf was carried out by
Ferns in an Angiosperm World: Cretaceous Radiation into the Epiphytic Niche and Diversification on the Forest Floor
TLDR
A number of functional aspects of fern biology are reviewed to include both gametophytic and sporophytic physiology, and it is possible that angiosperms engineered conditions that lead to aseasonal tropical forests and that wetter forests may have facilitated fern diversification.

The occurrence of crassulacean acid metabolism among vascular epiphytes from Central Panama.
TLDR
Investigation of the occurrence of crassulacean acid metabolism among the epiphyte flora of the lowland forest on Barro Colorado Island, Panama found indications of CAM were found in 29 species of three families, Orchidaceae, Bromeliaceae, and Cactaceae.
Regulation of Crassulacean Acid Metabolism by Water Status in the C3/CAM Intermediate Sedum telephium
TLDR
C3/CAM intermediates offer a model system that can be used to investigate metabolic regulation and gene expression in relation to environmental factors, and are of great interest in terms of evolution and plant adaptation to the environment.
Degrees of crassulacean acid metabolism in tropical epiphytic and lithophytic ferns
TLDR
It is suggested that CAM may be more prevalent in tropical epiphytic and lithophytic ferns than currently envisaged and carbon isotope ratios may not, by themselves, be sufficient for the identification of weak CAM.
Crassulacean acid metabolism in the epiphytic ferns Drymoglossum piloselloides and Pyrrosia longifolia: studies on responses to environmental signals
TLDR
The observed responses of the ferns to temperature changes suggest that the in situ environmental conditions are optimal for their CAM performance, and the results are discussed, in particular, in relation to CAM performance of epiphytes growing in the wet tropics.
Crassulacean acid metabolism in australian vascular epiphytes and some related species
TLDR
It is concluded that CAM is widespread in Australian epiphytes, most prevalent in species found in exposed microhabitats where the growing conditions are characterised by relatively high light intensities and short but frequent periods of water stress.
Mode of photosynthesis during different life stages of hemiepiphytic Clusia species.
TLDR
The expression of CAM in the three Clusia species is not developmentally controlled but triggered by environmental factors such as water availability and light intensity, and these factors remain relatively stable in this ecosystem and CAM is therefore not fully expressed.
Gas Exchange and Water Relations in Epiphytic Tropical Ferns
TLDR
This chapter will discuss recent results obtained by investigations in the laboratory as well as some in situ studies on tropical epiphytic ferns growing in their natural stands in Singapore.
Diffusive Resistance, Titratable Acidity, and CO 2 Fixation in Two Tropical Epiphytic Ferns
TLDR
There is further evidence to support the previous findings that certain epiphytic ferns do exhibit characteristics of CAM plants and diurnal changes in titratable acidity of Drymoglossum, Pyrrosia, and Kalanchoe were similar.
Evolutionary Aspects of Crassulacean Acid Metabolism in the Crassulaceae
The CAM pathway is taxonomically widespread and is believed to be used by about 16 000 species of vascular plants (see p. 9), a figure that includes more than 6% of all angiosperms. In addition, CAM
Water stress in the epiphytic orchid, Dimerandra emarginata (G. Meyer) Hoehne
TLDR
Comparisons of calculated daily water loss, PWC and the length of drought periods suggest that D. emarginata can only survive a dry season by drawing on the water reserves of older stems and by an efficient uptake of the occasional rain.
