Periods of such magnitude allow the dynamics of water flux within the organism and between it and its microenvironment to be appreciated, and when enough is known about both fluxes it should be possible to predict from measurements of the physical environment the hydration state of a part

And using similar reasoning, it may be that many prostigmatid mites in deserts also have this kind of life cycle. The same may hold for some Collembola as well, although the recent discovery of an

They have in common a diet consisting mainly of living or dead plant material, and a longevity of several to many years. These traits are associated with life-history options that, in the uncertain environments of deserts, a

Scolopendromorph centipedes add moderately to the remaining taxa, as most likely do some of the large carabid beetles, but very little is known about the life histories of either in arid regions.

Instead, we shall emphasize the fauna we do know something about, namely the free-living nematodes, a great variety of mostly prostigmatid mites, and the Collembola (Fig. 37).
