The Southwest Biological Science Center (SBSC) conducts quality, objective research on the lands and aquatic systems of the Southwest. This research can assist those who manage, conserve, and rehabilitate the arid regions of the nation. Click on SCIENCE in the sidebar to the left to explore SBSC science in more detail.
The Terrestrial Dryland Ecology (TDE) Branch of the SBSC studies the biology, ecology,and processes of semi-arid and arid lands (known as drylands). TDE researchers study plant-soil-water relationships and the wildlife found in drylands.TDE Science
The River Ecosystem Science (RES) Branch of the SBSC, which includes the Grand Canyon Monitoring and Research Center (GCMRC), studies the biology, ecology, and processes of the rivers in the Southwest.RES (GCMRC) Science

Several news sources have reported on a recently published paper by Travis Nauman and Mike Duniway titled, “Disturbance automated reference toolset (DART): assessing patterns in ecological recovery from energy development on the Colorado Plateau”.
A new scientific approach can now provide regional assessments of land recovery following oil and gas drilling activities, according to a new U.S. Geological Survey study published in the journal Science of the Total Environment.
A video put out by CBS discusses some of the ecological issues of Arches and Canyonlands National Parks in UT such as nonnative annual grasses, disturbance caused by cattle grazing, and the difficulty of getting native, perennial grasses established. The video focuses on the research of SBSC’s Rebecca Mann and Mike Duniway, who are studying the use connectivity modifiers (ConMods) in restoration.
Aridity is an important environmental filter in the assembly of plant communities worldwide. The extent to which root traits mediate responses to aridity, and how they are coordinated with leaf traits, remains unclear. Here, we measured variation in root tissue density (RTD), specific root length (SRL), specific leaf area (SLA), and seed size within and among thirty perennial grass communities...
N2 fixation and ammonia oxidation (AO) are the two most important processes in the nitrogen (N) cycle of biological soil crusts (BSCs). We studied the short-term response of acetylene reduction assay (ARA) rates, an indicator of potential N2 fixation, and AO rates to temperature (T, -5°C to 35°C) in BSC of different successional stages along the BSC ecological succession and geographic origin (...
Drylands cover 40% of the global terrestrial surface and provide important ecosystem services. While drylands as a whole are expected to increase in extent and aridity in coming decades, temperature and precipitation forecasts vary by latitude and geographic region suggesting different trajectories for tropical, subtropical, and temperate drylands. Uncertainty in the future of tropical and...
