he Schweitzer Lab works on the linkages and feedbacks between above- and belowground processes in terrestrial ecosystems. We are interested in biodiversity studies emphasizing quantitative, experimental, and multidisciplinary approaches to fundamental ecological and evolutionary questions. We examine the role of plant-soil linkages and feedbacks to soils and nutrient cycling and the ecological and evolutionary importance of these linkages to both soils and plants. This approach takes an integrative approach to both the biotic and abiotic factors that govern species interactions. We work in a range of contexts in global change including invasion biology, climatic change and biodiversity and ecosystem function – the results of which have both applied and theoretical importance to the conservation and sustainability of natural ecosystems.
