Although dew deposition on plant leaves has potential physiological consequences for some plants, it has received little attention.
It seems that epiphytic bromeliads may also rely on alternative sources of water, such as fog or dew.
During the early dry season, dew increased with height and maximal dew amounts occurred at 2.85 m above ground.
A dew-point apparatus, which enabled a sample of air from a given place to be drawn into a chamber with the mirror, was tried.
Here we report on a numerical model that simulates the transport of dew and low levels of rain in undersaturated desert soil.
Finer-scale variations amongst the two deserts, however, cannot be explained solely by rainfall, but instead indicate fog and/or dew may be important moisture sources.
They survive by occupying the endolithic niche among the hygroscopic halite crystals, which is able to condense moisture from occasional fog or dew.
The results indicate that dew formation was quite frequent and could have an important role in the growth and survival of some epiphytic bromeliads.
