What does a “resilient” forest look like in California’s Sierra Nevada? A lot fewer trees than we’re used to, according to a study of frequent-fire forests from the University of California, Davis.

More than a century ago, Sierra Nevada forests faced almost no competition from neighboring trees for resources. The tree densities of the late 1900s would astonish most Californians today. Because of fire suppression, trees in current forests live alongside six to seven times as many trees as their ancestors did — competing for less water amid drier and hotter conditions.

Giving 1,200-pound cows access to one of California's most fragile and biologically rich ecosystems seems a strange way to protect its threatened and endangered species.

Study of a rice field in Asia found that selective breeding and management decisions maintained crop yields despite climate changes, but those interventions weren’t enough to increase production to meet global demand, according to a paper from University of California, Davis.

Pima cotton is the predominant variety of cotton grown in California. It’s ideal for making premium fabrics for clothing and bed sheets. But Fusarium wilt disease, caused by a soil-borne fungus, can devastate a cotton crop. It’s responsible for crop losses in several production regions in the U.S. and worldwide. 

Gene editing can improve crop performance, but there’s a catch: It can be hard to grow plants from cells after you’ve tweaked their genomes.

At 5 feet, 2 inches, Plant Sciences Professor Emerita Barbara D. Webster may have been petite in stature, but she was a powerhouse when it came to reducing barriers for women in academia.

“She was formidable,” said her daughter, Susan V. Webster, with a chuckle. “She didn’t back down.”

Four years after plant sciences professor Kentaro Inoue was struck and killed while riding his bike, the last three graduate students from his lab are ensuring his scientific legacy lives on through their published research, careers in industry and academia, and mentoring of future science students.

Two UC Davis students—Abelina Jackson and Saarah Kuzay—are among those who have been selected as 2020 Borlaug Scholars by the National Association of Plant Breeders (NAPB).

The Borlaug Scholars Program seeks to strengthen the plant breeding profession by helping support attendance of future leaders at the NAPB annual meeting. However, this year’s annual meeting will be held in a virtual format because of COVID-19 concerns. Each student will receive free registration for the conference and a membership in NAPB.

Big data is all around us –– even in the wine we drink. UC Davis’ Smart Farm Big Idea is tackling how to take some of this vast trove of information and synthesize it for the benefit of agriculture.

Mason Earles, assistant professor in the Department of Viticulture and Enology and the Department of Biological and Agricultural Engineering, is applying big data by merging agricultural and machine learning to glean information that improves vineyards’ health and yields.

The UC Davis Public Scholarship and Engagement Program has awarded funding to 14 new research projects, including five to faculty in the College of Agricultural and Environmental Sciences, that will address diverse issues such as climate change, the welfare of families, and cultivating a new grain crop.
