The Konza Prairie LTER program is based on a conceptual framework that recognizes fire, grazing, and climatic variability as essential and interactive factors shaping the structure and dynamics of grasslands across landscape mosaics. Our LTER goals are to test specific hypotheses regarding the independent and interactive ecological effects of these factors in mesic grasslands, and to evaluate the potential consequences of multiple global change phenomena. Our research program is also designed to elucidate the role of biotic interactions (competition, mutualism, predation, herbivory) in grassland communities and ecosystems, and provide insight into more general ecological phenomenon with applicability to multiple ecological systems. Links at the left provide further information about our “core” LTER research activities, and a variety of other related studies underway at the Konza Prairie LTER site. More detailed information is also available in the most recent of our LTER proposals.
