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

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.

Economic assessment of surface water in the Harney Basin, Oregon

Executive SummaryThe Harney Basin is a closed river basin in southeastern Oregon. Surface water in the basin is used for a variety of social, economic, and ecological benefits. While some surface water uses compete with one another, others are complementary or jointly produce multiple beneficial outcomes. The objective of this study is to conduct...

Drought resistance and resilience: The role of soil moisture–plant interactions and legacies in a dryland ecosystem

In many regions of the world, climate change is projected to reduce water availability through changes in the hydrological cycle, including more frequent and intense droughts, as well as seasonal shifts in precipitation. In water-limited ecosystems, such as drylands, lower soil water availability may exceed the adaptive capacity of many organisms...

Analysis of Escherichia coli, total recoverable iron, and dissolved selenium concentrations, loading, and identifying data gaps for selected 303(d) listed streams, Grand Valley, western Colorado, 1980–2018

Tributaries to the Colorado River in the Grand Valley in western Colorado (segment COLCLC13b) have been placed on the State of Colorado 303(d) list as impaired for Escherichia coli (E. coli), total recoverable iron, and dissolved selenium. The Colorado Department of Public Health and Environment Water Quality Control Division is required to...
