ПРОСТОРОВА МІНЛИВІСТЬ ЕЛЕКТРОПРОВІДНОСТІ ҐРУНТУ ПІД ВПЛИВОМ РИЙНОЇ АКТИВНОСТІ СЛІПАКІВ НА РІЗНИХ МАСШТАБНИХ РІВНЯХ

The soil mounds emerged owing to the mole rats’ digging activity have been shown to be characterised by less electrical conductivity than surrounded soil. This effect is due to the changes of the mounds bulk’s density and moisture. The effect of the mole rats’ digging activity on the soil electrical conductivity has been found not to be restricted by the geometrical border of the mounds. The mounds are surrounded by 1–1.5 m halo of increased soil electrical conductivity. The halo size is increased with the aging of the mound and with the compacting of their aggregation.
