The effect of magnetic field intensities on the oxygen consumption in Porcellio laevis latre (Oniscoidea, Isopoda).

The effects of the 5 gauss, 50 gauss and 500 gauss magnetic fields on the oxygen consumption in Porcellio laevis adults, at soil pH 3.8 and 7.0, were investigated in a series of laboratory experiments. The oxygen consumption was the highest at 5 gauss and pH 3.8, and lowest at 500 gauss and pH 7.0. Highest isopod mortality was recorded under all magnetic fields at pH 3.8, and lowest at pH 7.0. The significance of these findings is discussed.
