Plant scientists and wheat breeders now have a new tool to develop more nutritious and productive wheat varieties: A public online database of 10 million mutations in wheat genes. Scientists at UC Davis and three institutions in the UK created the database, which will allow scientists worldwide to study the function of every gene of wheat. The research will be reported in Proceedings of the National Academy of Sciences this week.
UC Davis Plant Sciences Professor, Jorge Dubcovsky is working to improve the yield and nutritional value of wheat, one of the world’s most important crops.

For the first time scientists can see how the shells of tiny marine organisms grow atom-by-atom, a new study reports. The advance provides new insights into the mechanisms of biomineralization and will improve our understanding of environmental change in Earth’s past.
Foraminifera are marine plankton with complex shells. The shells of dead forams in ocean sediments form a record of climate hundreds of millions of years into the past.
Led by researchers from the University of California, Davis and the University of Washington, with key support from the U.S. Department of Energy’s Pacific Northwest National Laboratory, the team examined an organic-mineral interface where the first calcium carbonate crystals start to appear in the shells of foraminifera, a type of plankton.

California’s coastal redwoods are one of the state’s most prominent icons, drawing more than 2 million visitors a year. Another prominent icon? Fog, winding its way across the coast and through the trees. Climate change may be impacting both of them.
Climate change may affect the fog that waters California’s iconic coastal redwoods.
While coastal redwoods typically get plenty of water during the winter, fog helps them get through the summer. But fog is on the decline. What that means for the coastal redwoods in currently unclear.
Under certain conditions, forests can grow in response to climate change

After a tip-off from nomadic herders, a team of scientists has confirmed reports of a forest expansion in eastern Tibet, a region dominated by ancient grasslands. The forest growth, unprecedented since 1760, is due to a combination of climatic changes: rising atmospheric carbon dioxide, increased water related to warming, and greater nutrient availability released by thawing permafrost.

The world’s coral reefs are both stunningly beautiful and vital to ocean health, hosting a huge diversity of fish and marine life. And they are, as they always have been, under pressure from periodic natural disasters. However, a coral reef’s ability to recover from unavoidable and often unpredictable natural disasters, like hurricanes and tsunamis, may depend on human activities including fishing and pollution. UC Davis marine biologist Mike Gil is one of the scientists working to understand how reefs recover from natural disturbances in the presence of unnatural, man-made stressors.

As the November 2015 Global Climate Change Conference COP21 concluded in Paris, 196 countries reached agreement on the reduction of fossil fuel use and emissions in the production and consumption of energy, even to the extent of potentially phasing out fossil fuels out entirely.
Both globally and in the U.S., energy production and use, as well as the transportation sectors, are the largest anthropogenic contributors of greenhouse gasses (GHG), which are believed to drive climate change. While there is scientific consensus regarding the relative importance of fossil fuel use, anti animal-agriculture advocates portray the idea that livestock is to blame for a lion’s share of the contributions to total GHG emissions.

Global carbon dioxide emissions are triggering permanent changes to ocean chemistry along the West Coast. Failure to act on this fundamental change in seawater chemistry, known as ocean acidification, is expected to have devastating ecological consequences for the West Coast in the decades to come, warns a multistate panel of scientists, including two from UC Davis Bodega Marine Laboratory.
Their report, issued this week, urges immediate action and outlines a regional strategy to combat the alarming global changes underway. Inaction now will reduce options and impose higher costs later, the report said.

Beloved by beach goers, tide pools are also important ecological zones that provide shelter and food for many plants and animals.
Marine life living in tide pools are vulnerable to rising acid levels in seawater, according to new research from UC Davis, the Carnegie Institution for Science and UC Santa Cruz published March 18 in the journal Scientific Reports.

It’s hard to manage what you don’t measure.
UC Davis is playing a major role in solving California’s biggest water woes by joining forces across the UC system. The UC Water Security and Sustainability Research Initiative aims to account for all of California’s water, better understand how and where it flows, and help demonstrate how water can be managed differently to allow for greater water security.
If you think it’s been a bit chilly in the Sacramento region this week, spare a thought for UC Davis alumnus Refael Klein, lieutenant junior grade in the Commissioned Officer Corps of the National Oceanic and Atmospheric Administration. On a recent day temperatures climbed to 35 degrees below zero Fahrenheit at the South Pole, Klein’s home for the next year.

“It’s been a big dream of mine to visit Antarctica,” said Klein in an interview before he left the U.S. “I feel very fortunate to have the opportunity.”
