Together, these studies provide growing evidence for the importance of assembly processes in determining microbial community properties. They hypothesized that the relative importance of stochastic vs.
Species are most commonly defined through the biological species concept promoted by Mayr 4 a genetic definition that envisages a species as a group of interbreeding individuals that is isolated from other such groups by bar- riers to recombination.
No use, distribution or reproduction is permitted which does not comply with these terms. They found that associations between plants and microbial community composition were less pronounced at higher elevations, likely due to an increase in the influence of physical harshness on community composition.
From the limited amount of largely disjointed metagenomic and functional data obtained to date, extensive intra- and inter-system as well as extensive intra- and inter-population differences are apparent. Microbial ecologists are beginning to actively draw upon ecological theories from macro ecology to study microbial communities.
These interactions are shaped by a complex set of selective forces, which include both host and microbially-derived selective pressures. In particular, our understanding of microbial population-level differentiation involved in ecological adaptation that leads to microbial divergence and speciation has been profoundly altered.
In perspective, we suggest that the study of microbial community dynamics can not only benefit from applying ecological theories originally developed in macro ecology, but also contribute to the development and testing of new ecological theories. Our planet is experiencing rates of environmental change unprecedented in modern times, and an understanding of how microbes both mediate and respond to these shifts is an important research challenge De Vries and Shade, In the following sections we discuss examples of areas of ecological theory that might be particularly valuable in microbial ecology.

This book synthesises current viewpoints and knowledge on microbial ecological theory. Microbial ecologists are beginning to actively draw upon ecological theories from macro ecology to study microbial communities. For example, they propose that structure is not likely to be relevant for organic matter breakdown in mineral soils, where diffusion is limited and organic particles may be occluded or sorbed to soil surfaces.
Hallmarks of Microbial Adaptation, Divergence and Speciation? A wide range of bacteria inhabit intercellular spaces but only a few are true endosymbionts able to penetrate living cells whilst remaining membrane-bound, accessing plant carbon compounds in a manner analogous to biotrophic pathogens.
Numerous processes that underlie microbial differentiation have been identified but determining the relative significance of these processes remains challenging. Consequently, it is difficult to ascertain specific molecular patterns that define specific microbial groups that would be congruent with the definition of a microbial species.
Both secrete factors prior to contacting plant cells which appear to prepare the hosts for mutual rather than pathogenic interactions and suppress the defence mechanisms.These papers have been widely accessed and are directly applicable to the development of policy, and the microbiome plays a key role in the control and competence of insect crop pests and vectors of disease The role of ecological theory in microbial ecology.

Nat Rev Microbiol 5: – The human-microbial ecosystem plays a variety of important roles in human health and disease. Each person can be viewed as an island-like “patch” of habitat occupied by microbial assemblages formed by the fundamental processes of community ecology: dispersal, local diversification, environmental selection, and ecological drift.
Community assembly theory, and metacommunity theory. The authors demonstrate how the application of macro-ecological theory to the microbial world is not only enhancing our understanding of microbial ecology but also providing a reference point for the development of new theories.
In the following sections we discuss examples of areas of ecological theory that might be particularly valuable in microbial ecology. but this NATURE REVIEWS | MICROBIOLOGY might not lead to simple mapping between molecular markers and an ecological niche.
