A small, representative system having analogies to a larger system in constitution, configuration, or development: "He sees the auto industry as a microcosm of the U.S. itself" (William J. Hampton).

mi′cro·cos′mi·cal·ly adv.

microcosm

  1. an entity which is a miniature version of a more common, extensive whole.
  2. a controlled laboratory system that contains the necessary components of the ECOSYSTEM being studied. Microcosms are designed to simulate natural systems, but are likely to be simplified versions of such systems and thus may exclude or alter certain of the processes that occur naturally A microcosm may represent a portion of a natural system, that has been brought into the laboratory with the INDIGENOUS ORGANISMS and processes relatively undisturbed. Alternatively, a microcosm may be constructed in the laboratory as a simpler representation of the natural system, so that certain biological factors can be studied. The limitations of any particular microcosm must be fully understood when interpreting the results obtained from it.

We predict that, under sufficiently low [O.sub.2] conditions, nutrient levels would begin to dominate, and, under optimal [O.sub.2] and nutrient conditions, the physical dimensions of the microcosm would become important with large SA/V ratios favouring the Wrinkly Spreader and low ratios possibly selecting for low-[O.sub.2]-adapted mutants.
The second section on lyrical microcosm is also excellent, though perhaps not as consistently so.
Five gram of soil was placed into a 120 mL crimp top serum vial for microcosm construction.
I am running out of space to list more Valve Microcosms --and there are very many--but if you see the pattern, you can invent your own without much ado.
Each microcosm was sampled on the first day of the experiment and then at 2, 4, 6, 8, 10, 12, 14, 16, and 20 wks (9 sampling dates) during the incubation.
Water samples were collected at the sediment-water interface of each microcosm (i.e., the microcosm water column) using a syringe attached to a silicone hose.
That's why Microcosm began their campaign in January, at the very peak of the "Buyer's Remorse" season.
Over time, however, headspace flushing of the microcosm bottles became a less frequent requirement, as the molar ratio between [O.sub.2] and [CO.sub.2] remained high enough to support microbial degradation of organic contaminants.
Between the 19 and 26 Dec., microcosm temperatures decreased from about 9 to 4 C, an average decline of about 0.7 C [d.sup.-1] We compared the temperatures in our microcosms to those of two nearby sections of the Trinity River that are monitored daily by the U.S.
The objective of this microcosm study was to elucidate the effects of soil macrofauna on SOM decomposition and accumulation in the mineral layer in a central Florida hardwood forest with specific reference to the role of A.
Purposeful perception is sensation and in order to understand more deeply that sensation it is necessary, in the beginning, to be able to distinguish sensation in a macrocosm (spontaneously) from sensation in a microcosm (through the device).
Fittingly, when designing this modest house on a typically cramped Tokyo site, the architect chose to create Fuji in microcosm: an unreachable subject of contemplation.
