RESULTS
A total of 1719 beetle specimens and 395 spider specimens were captured across three habitats at the three farms during the experiment. Three of the spider specimens were damaged beyond recognition in the traps and were not included in the analysis. Beetle diversity was slightly lower in edge habitat than in crop and forest habitats (Fig. 1), although ANOVA of Simpson's indices indicated that diversity did not differ significantly across the three habitat types (Table 1). In contrast, ANOVA revealed that spider diversity was significantly affected by habitat type Table 20, with densities higher in forest fragments than in edge habitat( Tukey's HSD multiple comparison test, P 0.047; Fig. 2) Beetle and spider family types and abundance differed substantially among habitats(Tables 3, 4). Sorensen quantitative index analyses revealed that there was little overlap in beetle families across the three habitats (Table 5). The same was true for spiders, except that there was slightly more overlap among spider families between crop and edge habitats (Table 6).
