The impact of the electromagnetic fields on the living organisms and their communities

The small terrestrial invertebrates can be regarded as extremely suitable for assessing impacts of the electromagnetic (EM) fields on the living organisms. They have a limited migration ability and a comparatively quick reproduction cycle. Therefore, they may be easily exposed to the EM fields during several generations. The results has proved the intensive impact of the EM fields, mainly on the ecological structure, composition of the communities, and on the morphological, physiological and ethological phenomena of some selected species. The insects communities in our research were for a long period to the EM waves with the intensity of the electrical field higher than 100-150 V/m, that is the natural electrical field of the Earth's atmosphere, and to the magnetic field with the intensity higher, than 32-56 A/m. The EM fields cause the long-term changes in the species distribution in the terrestrial ecosystems. The species compositions were also compared with those existing in the non-stressed regions, which are considered to be typical for their natural habitats.
