 abstract={The number of ant species and the size of their colonies decrease in the areas where sheep were penned-up. The foraging activity of ants of the genus Myrmica is higher in these areas, which results in a higher colony biomass production and in a more rapid development of young generation. The foraging activity of Lasius niger L. decreases in the area of a sheep-fold, which is followed by a decrease in the production of the colony and comparatively slow development of young generation. The dominant species consume in the sheep-fold about 150 mg per m2 of dry organic matter of plant and animal origin, while in the grazed pasture 1200 mg. These values correspond to 0.01 and 0.11% of primary production, respectively.},
