Welti, Ellen
Research Ecologist, Great Plains Science Program, Conservation Ecology Center, Smithsonian Conservation Biology Insitute
Ellen Welti is a community ecologist working on grassland insects and plants. She is part of the Great Plains Science Program, based in the prairies of north central Montana. She runs observational monitoring targeting grasshoppers, dung beetles, wolf spiders, plant composition, and plant biomass. Her research topics include the function of insects in grasslands, plant-insect interactions, ecological time series, and plant and insect responses to altered biogeochemistry.
