The current knowledge of the physiological ecology of vascular epiphytes is reviewed here with an emphasis on the most recent literature. It is argued that by far the most relevant abiotic constraint for growth and vegetative function of vascular epiphytes is water shortage, while other factors such as nutrient availability or irradiation, are generally of inferior importance. However, it is shown that the present understanding of epiphyte biology is still highly biased, both taxonomically and…

Mechanisms Regulating Epiphytic Plant Diversity
- Environmental Science
- 2012
Six putative mechanisms of epiphyte species diversity are identified, and possible direct and indirect linkages among the mechanisms are highlighted, including constrained dispersal, slow growth rate, substrate availability, host tree mortality, disturbance, and global climate change.

This is the first study to test the combined effects of area, isolation and resident plant richness on epiphytic plant assemblage structure in New Zealand, southern Chile, and Australia and suggests that plant communities are structured by dispersal.
Ecological stoichiometry of the epiphyte community in a subtropical forest canopy

The results suggest that epiphytes may have evolved specific nutrient characteristics and adaptations, so that they can distribute in heterogeneous canopy habitats and maintain the stability of nutrient metabolism.
The contribution of microorganisms and metazoans to mineral nutrition in bromeliads
- Environmental Science
- 2016
Evidence that bromeliads have evolved multi-faceted nutritional strategies to respond to fluctuations in the supply of natural nitrogen is reviewed, indicating that there have been convergent adaptations to nutrient scarcity.
Interactions of Epiphytes with Precipitation Partitioning
- Environmental Science
- 2020
Epiphytes are structurally-dependent plants which grow on other plants without taking nourishment from them. Phylogenetic and ecophysiological differences divide them into non-vascular epiphytes…

Plant size and intraspecific variability in vascular epiphytes
- Environmental Science
- 2001
From habitat conditions it seems that size-related differences in water availability are the driving force behind the observed size-dependent ecophysiological changes: the larger an epiphyte grows the more independent it is with regard to precipitation patterns.
