After 1 month, the incubated samples were reexamined for changes in inorganic nitrogen concentrations. Differences in the cumulative values among fragmentation treatments were insignificant as measured by analysis of variance (ANOVA) tests

Plant data are from 13 censuses, from the fall of 1984 through the fall of 1989. All plants were identified, and the percent cover was measured by means of a modified point-frame method in permanently positioned 1 -M2 quadrats. Thirty quadrats were sampled in each large patch, four in each medium patch, and two in each small patch. Patch size differences in cumulative species counts were not significant as measured by ANOVA tests

Species evenness was calculated as$ where pi is the proportional representation (relative percent cover of plants or number of individuals for arthropods) of each species. Higher values indicate more even representation of multiple species; lower values indicate dominance by fewer species

The site had been in a wheat-soybean rotation before the initiation of the experiment. The patch array was created immediately after a final winter wheat harvest. Natural vegetation of the region is a mosaic of open prairie, successional woodlands, and mature deciduous forest
