Impact of Extremely Low Frequency Electromagnetic Fields on Soil Arthropods. Ongoing Studies at the Wisconsin Test Facility.
Abstract
Possible Sanguine impact on soil arthropods was studied in 11 test plots and six control plots. As in 1971, no significant differences occurred between each of the four arthropods in main test and control supplots. Statistically significant differences occurred in some of the other plots in 1972, not observed in 1971. In some, a population was higher in the test plot; in others, it was higher in the control. A general feature of all arthropods in all plots is a mid-summer population peak with return by mid-September to spring levels. Within-plot population changes due to random, natural causes complicate analyses. Therefore, less reliance should be placed on variation in absolute numbers than on inter-group ratios and annual population curves to provide evidence for significant population shifts.
