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.

Changes in prey, turbidity, and competition reduce somatic growth and cause the collapse of a fish population

Somatic growth exerts strong control on patterns in the abundance of animal populations via effects on maturation, fecundity, and survival rates of juveniles and adults. In this paper, we quantify abiotic and biotic drivers of rainbow trout growth in the Colorado River, AZ, and the resulting impact on spatial and temporal variation in abundance....

Nitrogen enrichment reduces nitrogen and phosphorus resorption through changes to species resorption and plant community composition

Anthropogenic nitrogen (N) deposition has affected plant community composition and nutrient cycling in terrestrial ecosystems worldwide. This includes changes to the way plants use and recycle nutrients, including effects on nutrient resorption, which is a key process through which plants recover nutrients from tissue during senescence. Nutrient...

Post-fire growth of seeded and planted big sagebrush - Strategic designs for restoring Greater Sage-grouse nesting habitat

Wildfires change plant community structure and impact wildlife habitat and population dynamics. Recent wildfire‐induced losses of big sagebrush (Artemisia tridentata) in North American shrublands are outpacing natural recovery and leading to substantial losses in habitat for sagebrush‐obligate species such as Greater Sage‐grouse. Managers are...
