Southwest Biological Science Center
Home
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.
Terrestrial Dryland Ecology Branch
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 ScienceRiver Ecosystem Science Branch
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.

Future Temperature and Soil Moisture May Alter Location of Agricultural Regions
Future high temperature extremes and soil moisture conditions may cause some regions to become more suitable for rainfed, or non-irrigated, agriculture, while causing other areas to lose suitable farmland, according to a new U.S. Geological Survey study.
Increases in Wildfire-Caused Erosion Could Impact Water Supply and Quality in the West
A growing number of wildfire-burned areas throughout the western United States are expected to increase soil erosion rates within watersheds, causing more sediment to be present in downstream rivers and reservoirs, according to a new study by the U.S. Geological Survey.
Wildfire and Invasive Species Drives Increasing Size and Cost of Public Land Restoration Efforts
An examination of long-term data for lands managed by the Bureau of Land Management finds that land treatments in the southwestern United States are increasingly large, expensive and related to fire and invasive species control.

Landscape-scale wildlife species richness metrics to inform wind and solar energy facility siting: An Arizona case study
The juxtaposition of wildlife and wind or solar energy facility infrastructure can present problems for developers, planners, policy makers, and management agencies. Guidance on siting of these renewable energy facilities may help identify potential wildlife-facility conflicts with species of regulatory or economic concern. However, existing...
Thomas, Kathryn A.; Jarchow, Christopher; Arundel, Terry; Jamwal, Pankaj; Borens, Amanda; Drost, Charles A. Soil water dynamics at 15 locations distributed across a desert landscape: insights from a 27‐yr dataset
Desert ecosystems are primarily limited by water availability. Within a climatic regime, topography, soil characteristics, and vegetation are expected to determine how the combined effects of precipitation, temperature, and evaporative demand of the atmosphere shape the spatial and temporal patterns of water within the soil profile and across a...
