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 & GCMRC
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 rivers in the western United States, with an emphasis on the Southwest.

USGS Press Release: Plant age drives mortality, reproductive success and population dynamics
A USGS press release was published today highlighting a paper describing possible limitations of big sagebrush restoration in the American West after wildfires.
Why Sagebrush Re-establishment After Fire is so Difficult
Big sagebrush ecosystems are particularly sensitive to wildfires and life history information on big sagebrush is scarce and vital for restoration success.
SBSC Research on Barred and Spotted Owls Covered by Ecological Society of America
The Ecological Society of America put out a press release on a paper that investigated the relative importance of barred owl competition and habitat on northern spotted owls in an effort to assist managers. The lead author of the paper is Charles Yackulic of the USGS Southwest Biological Science Center.

The U.S. Geological Survey Southwest Biological Science Center—Sound science to serve the American Southwest
Home to Arches, Grand Canyon, and Saguaro National Parks, among others, the American Southwest’s landscapes are as fragile as they are iconic. Energy development, water security, and grassland restoration are important to the region as it experiences population growth and increased demand for resources. The U.S. Geological Survey’s Southwest...
Biological Science Center Staff, Southwest Earlier plant growth helps compensate for reduced carbon fixation after 13 years of warming
1. Drylands play a dominant role in global carbon cycling and are particularly vulnerable to increasing temperatures, but our understanding of how dryland ecosystems will respond to climatic change remains notably poor. Considering that the area of drylands is projected to increase 11–23% by 2100, understanding the impacts of warming on the...
