SynopsisThe general environmental factors controlling the epiphytic vegetation on birch are discussed, as is the physio-chemical nature of birch bark as a substratum for epiphytes (especially lichens). In terms of species diversity, birch is found to be a poor host (phorophyte) for epiphytes and various reasons (e.g. low bark pH) for this are suggested.

POPULATION VARIATIONS OF EPIPHYTIC BACTERIA
Canadian Journal of Microbiology, 1967Stained bacteria were observed on the surface of bleached leaves. On most plants in Puerto Rico, bacteria were absent during dry weather and were found in varying numbers with the onset of a rainy period. In Ohio, there were a few or no bacteria on leaves of crop plants sampled at different times during the growing season.

In all aquatic environments, available surfaces are rapidly colonized by a variety of organisms. If these organisms grow on plants they are called epiphytes. Seagrasses provide an excellent substratum for epiphytic organisms and these organisms are an integral component of seagrass ecosystems.

Epiphytic microorganisms and IAA synthesis
Planta, 1968Epiphytic microorganisms present on cotton plants synthesized 3-indoleacetic acid (IAA) from tryptophan. Microorganisms from the root zone synthesized 3 times the amount of IAA when compared with the shoot zone and the root zone contained a much higher number of microorganisms. IAA-synthesizing activity was eliminated when the tissues were treated with

Epiphytes existed in forests and other vegetation long before the advent of human civilization and the current human domination of the globe. As part of the forest, epiphytes were affected by human activities without being the actual target, e.g., when slash-and-burn agriculture was used for subsistence.

Epilithic or saxicolous bryophytes may be defined as those growing directly on the surface of rock, and in this chapter do not include aquatic species; epiphytic or corticolous species are those growing on the bark of living trees and shrubs. In the literature, authors dealing with epiphytes usually adhere strictly to the above definition, probably ...
