Effects of bison grazing, fire, and topography on floristic diversity in tallgrass prairie.
Grazed and ungrazed sites subjected to different fire frequencies were sampled on the Konza Prairie Research Natural Area in northeast Kansas after 4 years of bison grazing (1987-1991). The objective… Expand

Invasive warm-season grasses reduce mycorrhizal root colonization and biomass production of native prairie grasses
Soil organisms play important roles in regulating ecosystem-level processes and the association of arbuscular mycorrhizal (AM) fungi with a plant species can be a central force shaping plant species’… Expand
