“…Yet beyond this, it is widely believed that evolutionary forces also apply at the level of ecosystems [144] with the evolutionary goal, as with all biological systems, to develop a controlled response amidst a background of environmental noise and fluctuation. Replication of biological order on the species level interacts with the disorder introduced by noise and changing selection pressures to produce the appearance of criticality on the ecological scale [145].…”

Second-generation sequencing technologies have granted us greater access to the diversity and genetics of microbial communities that naturally reside endo-and ecto-symbiotically with animal hosts. Substantial research has emerged describing the diversity and broader trends that exist within and between host species and their associated microbial ecosystems, yet the application of these data to our evolutionary understanding of microbiomes appears fragmented. For the most part biological perspectives are based on limited observations of oversimplified communities, while mathematical and/or computational modeling of these concepts often lack biological precedence. In recognition of this disconnect, both fields have attempted to incorporate ecological theories, although their applicability is currently a subject of debate because most ecological theories were developed based on observations of macro-organisms and their ecosystems. For the OPEN ACCESSEntropy 2011, 13 571 purposes of this review, we attempt to transcend the biological, ecological and computational realms, drawing on extensive literature, to forge a useful framework that can, at a minimum be built upon, but ideally will shape the hypotheses of each field as they move forward. In evaluating the top-down selection pressures that are exerted on a microbiome we find cause to warrant reconsideration of the much-maligned theory of multi-level selection and reason that complexity must be underscored by modularity.

“…The term relates to the "Community Theory" originally proposed by Caldwell et al 11) , which was based on the supposition that changes or constraints in the environment influence entire microbial populations instead of affecting each individual species independently. In this case, microorganisms proliferate in response to the environment, evolving into a biological network that is most suitable for survival and/or further growth ("Proliferation Hypothesis").…”

“…It is assumed that individual species in a microbial community interact and communicate with each other to support and sustain themselves, and the loss of any component species or the stable community structure could risk the function of the entire community. Examples of such stable, inter-dependent microbial communities include anaerobic digestor granules, degradative consortia, spoilage and corrosion biofilms, and kefir 11) .…”

A distinct microbial community is established in a given environment as a consequence of the community evolution of individual component microorganisms. According to the "Community Theory", microorganisms proliferate not as individual species but as a community in response to changes in the environment, evolving into a biological network that is most suitable for their survival and/or further growth. During this process, individual microorganisms interact and communicate with each other by sharing their limited genetic information in order to exploit available resources. Consequently, a functional community comprising many different species is formed. Such microbial communities are comparable to multi-cellular organisms in many ways, but often too complex to be characterized. Nutrient enrichment is one approach to the study of the functions of these inextricably linked biological networks. For soil microbial communities, amendment with organic matter can be employed to apply selective environmental advantages in order to transfer microbial communities to newly evolved biological consortia with distinctive functions. Many studies have reported that the incorporation of composts or green manures rendered soils suppressive to various soilborne pathogens. Among the pathogens that are controlled effectively are Pythium, Phytophthora, and Rhizoctonia. Soil enrichment with organic matter may be the most fundamental and sustainable approach to the biological control of soilborne diseases.
