Modern microbial ecology was launched by Robert Hungate and coworkers, who investigated the rumen ecosystem. The study of the rumen required Hungate to develop techniques for culturing anaerobic microbes, and he also pioneered a quantitative approach to the study of microbes and their ecological activities that differentiated the relative ...
At the same time it represents thousands of populations accounting for most of the phylogenetic diversity in an ecosystem. This low-abundance high-diversity group is the rare biosphere. Using this method, Sogin et al.’s study of microbial diversity in North Atlantic deep water produced an estimate of 5266 different taxa. [11]
A 2016 paper by Brent Stephens [7] highlights some of the key findings of studies of "microbiomes of the indoor environment". These key findings include those listed below: "Culture-independent methods reveal vastly greater microbial diversity compared to culture-based methods" "Indoor spaces often harbor unique microbial communities"
These include the buccal region (especially cavities in the gingiva), rumen, caecum etc. of mammalian herbivores or even invertebrate digestive tracts.In the case of mammalian gastrointestinal microecology, microorganisms such as protozoa, bacteria, as well as curious incompletely defined organisms (such as certain large structurally complex Selenomonads, Quinella ovalis "Quin's Oval ...
The hydrothermal vent microbial community includes all unicellular organisms that live and reproduce in a chemically distinct area around hydrothermal vents. These include organisms in the microbial mat, free floating cells, or bacteria in an endosymbiotic relationship with animals. Chemolithoautotrophic bacteria derive nutrients and energy ...
Organisms evolve within ecosystems so that the change of one organism affects the change of others. The hologenome theory of evolution proposes that an object of natural selection is not the individual organism, but the organism together with its associated organisms, including its microbial communities. Coral reefs.
Access to the previously invisible world opened the eyes and the minds of the researchers of the seventeenth century. Antonie van Leeuwenhoek investigated diverse bacteria of various shapes, fungi, and protozoa, which he called animalcules, mainly from water, mud, and dental plaque samples, and discovered biofilms as a first indication of microorganisms interacting within complex communities.
The Deep Carbon Observatory's research considers the global carbon cycle beyond Earth's surface. It explores high-pressure and extreme temperature organic synthesis, complex interactions between organic molecules and minerals, conducts field observations of deep microbial ecosystems and of anomalies in petroleum geochemistry, and constructs theoretical models of lower crust and upper mantle ...
