Examples

  • To what extent can depth-scale effects observed in these mesocosm studies be extrapolated to nature?

    Academic text (2003)
  • For a given question and system, an "experimental window" of scale, in which mesocosms exhibit realistic ecological dynamics, can often be empirically determined.

    Academic text (2003)
  • Only one size of marsh mesocosm was used in the studies.

    Academic text (2003)
  • Three replicates of each mesocosm type were used in experiments.

    Academic text (2003)
  • Unique to this study, however, were the dramatic effects of mesocosm size, shape, and experimental duration on fish growth rates (Figure 9).

    Academic text (2003)
  • We tested our hypothesis for scale effects on among-system variability using data from planktonic-benthic mesocosm experiments.

    Academic text (2003)
  • The MEERC mesocosms were derived from and intended to serve as models of Chesapeake Bay ecosystems.

    Academic text (2003)
  • Fifteen cylindrical mesocosms were constructed, with five distinct dimensions, three volumes, and three replicates per dimension (Figure 5).

    Academic text (2003)
  • We found that in plankton-dominated mesocosms this "boom-bust" bloom cycle was substantially damped with continual addition of nutrients.

    Academic text (2003)
  • The researchers conducted tests in a series of mesocosms to measure the effects of pollutants on aquatic life.

Morphology

mesocosm = cosmos (semi-transparent) = meso + cosm + meso

The formation 'meso-' (middle/medium) + 'cosm(s)' (world/universe) gives 'middle-scale world' which suggests a medium-scale experimental system, but the specific technical meaning (a controlled experimental environment) is specialized and not fully predictable by a general B1 learner.

Etymology

Mesocosm comes from the Greek parts meso- meaning 'middle' and -cosm from cosmos meaning 'world'. A mesocosm is a 'middle world' — a medium-sized, controlled place between a tiny lab system called a microcosm and the whole natural world, the macrocosm, which is why scientists use mesocosms to study how nature works while still keeping control.
