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

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.

Population ecology of epiphytic angiosperms: A review

Epiphytic angiosperms represent ca. 10 % of the world's flowering plants and are key elements in tropical forests. Here we synthesize the available literature on their population ecology in an

Epiphytes: a study of the history of forest canopy research

The development of new and more versatile access techniques is a major contributor to the continuously growing field of canopy research. Methods such as cranes, canopy walkways, hot-air balloons,

Ecophysiology and Crassulacean Acid Metabolism of Tropical Epiphytes

Epiphytes are plants that germinate and grow upon other plants without contact with mineral soil and without parasitizing their host plant. Therefore, they derive nutrients and water from the

Divergent Adaptation Strategies of Vascular Facultative Epiphytes to Bark and Soil Habitats: Insights from Stoichiometry

The results implied that facultative epiphytes maintain stable metabolic leaf activity via variable element concentrations of roots to adapt to highly heterogeneous forest habitats.


Vascular epiphyte assemblage structure and distribution patterns in the south-temperate zone

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

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.



Plant size and intraspecific variability in vascular epiphytes

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.

Small plants, large plants: the importance of plant size for the physiological ecology of vascular epiphytes.

This short review will summarize what is known to date about this phenomenon, describe the possible mechanism and will discuss the consequences for the present understanding of epiphyte biology.

Bromeliaceae: Profile of an Adaptive Radiation

This book, first published in 2000, presents a synthesis of the extensive information available on the biology of Bromeliacea, a largely neotropical family of about 2700 described species, concentrates on function and underlying mechanisms.

Herbivory in the epiphyte, Vriesea sanguinolenta Cogn. & Marchal (Bromeliaceae)

Level of damage to photosynthetic tissue, mostly caused by the larvae of Napaea eucharilla (Riodinidae, Lepidoptera), indicate that vascular epiphytes may be regularly and sometimes even lethally attacked by insect herbivores.

15N natural abundance of vascular rainforest epiphytes: Implications for nitrogen source and acquisition

It is concluded that epiphytes may utilize N‐depleted nitrogen from atmospheric deposition and N fixation and that discrimination against N is an intrinsic function ofEpiphyte physiology.


The distribution of epiphytes among branches and trees and the rates of recruitment, growth and mortality of these subpopulations must be determined to understand the population dynamics.

Ecology of vascular epiphytes in West African rain forest

The ecology of 153 species of vascular epiphytes (101 orchids, 39 pteridophytes and 13 others) in the Nimba Mts in Liberia is described. 29 species are recorded in Liberia for the first time

Some Often Overlooked Plant Characteristics as Determinants of Plant Growth: A Reconsideration

Plant primary production is ultimately dependent on photosynthetic CO2 uptake. However, photosynthate production also depends on the amount of photosynthetically active tissue constructed by the

Cuticles of Vascular Epiphytes: Efficient Barriers for Water Loss after Stomatal Closure?

Water permeabilities of astomatous, isolated cuticular membranes of 15 vascular epiphyte species from the moist lowland forest of Barro Colorado Nature Monument, Panama, were investigated and showed the lowest cuticular permeances to water recorded to date.
