Forecasts favor above-average temperatures and below-average precipitation for the Rio Grande/Bravo Basin through January.
The UA College of Agriculture and Life Sciences partnered with the Water Resources Research Center and Arizona Public Media to take a deep dive into the water issues facing the Southwest and garnered this year's Rocky Mountain Emmy for Best Topical Documentary. WRRC director Sharon Megdal and her staff provided the film's producer with scientifically accurate information and a list of more than 60 water experts to interview, which included several UA researchers.
September precipitation was much-below average to below average across central and southeastern Arizona, while temperatures were below average to much-above average throughout the state. The three-month outlook for October through December calls for increased chances of below-average precipitation for most of Arizona and New Mexico, and increased chances of above-normal temperatures for the entire southwestern United States
The goals of the Sustainable Bioeconomy for Arid Regions Center will be to address the nation's needs for biofuels and bioproducts, strengthen Arizona's bioeconomy, and provide training for the next generation of scientists and engineers. Kimberly Ogden, director of the UA Institute for Energy Solutions, will head the Sustainable Bioeconomy for Arid Regions Center. Peter Waller and Dennis Ray, researchers from the College of Agriculture and Life Sciences, will also be involved with the center.
A new global assessment helps scientists explain why cases of pest resistance to genetically engineered crops increased by more than fivefold in the past decade, yet some pests remain suppressed. To test predictions about resistance, Bruce Tabashnik and Yves Carrière in the College of Agriculture and Life Sciences analyzed the global data on Bt crop use and pest responses.
Humans migrated out of Africa as the climate shifted from wet to dry about 60,000 years ago, according to new paleoclimate research. "Our data suggest that when most of our species left Africa, it was dry and not wet in northeast Africa," said Jessica Tierney, the UA associate professor of geosciences who led the study.
