The hypothesis was tested that microarthropod populations would exhibit greater increases in population densities and remain active longer under the same plant species at the base of a watershed where water and organic matter accumulate, than they would upper watershed locations. Only collembolans exhibited numerical responses as a function of moisture. Although soil moisture and organic content were greater in soils at the base of the watershed, soil microarthropods there exhibited less increase following rains than they did in upper watershed locations. Numerical responses of soil Acari were seasonal with maximum numbers in October at the end of the normal wet season (July-September) and were not correlated with soil moisture or soil organic matter. -Authors
