Biological research at DRI spans many spatial and temporal scales and environments from around the world. DRI scientists study how biota and ecosystems interact with the environment and how they respond to environmental change in diverse environments from the local Great Basin to Antarctica to mine shafts several miles deep. Scientists conduct research in extreme environments such as the Mojave Desert, the Dry Valleys of Antarctica and the Atacama Desert in Chile. Our scientists are also active in renewable energy research focusing on biomass crop production and assessing optimal environmental conditions for the production of algal biofuels. DEES scientists are working with federal agencies to conduct inventories of threatened and endangered plant and animal species to facilitate land use decisions for military training, and development of renewable energy. Our faculty have access to advanced analytical laboratories and controlled environment facilities, some of which are unique in the world.
