Overwintering cattle outdoors causes soil surface disturbance, substantial increases of soil N_tot, C_org, and P and a shift in pH to alkaline levels. Since fungi predominate in unfertilized soils with acidic pH and have filamentous hyphae, we hypothesized that changes caused by overwintering cattle outdoors (trampling, excreta returns, and changes in soil chemistry) will lead to suppressed species richness, lower biomass, and alter the structure of fungal communities. The research was conducted on an upland pasture used more than 10 years for cattle overwintering. Both culture-dependent and -independent methods were used for the determination of either fungal species composition (cultivation; DGGE) or biomass (numbers of CFU; concentration of fungal PLFA marker 18:2w6,9). Soils under three different levels of cattle disturbance (S - severe, M - moderate, C - no disturbance/control) were investigated during three subsequent years.
