Shy in high school, Rachel Fang didn’t want to follow the same pattern as a UC Merced student.

“I decided that I was going to change,” Fang said. “I wanted to be more outspoken.”

The discovery of a new, rare species of monkey flower by Professor Jason Sexton provides clues as to how new species are born.

Sexton, who researches the monkey flowers that grow wild throughout California, and are especially prolific in the Sierra Nevada, conducted this work with researchers Kathleen G. Ferris and John H. Willis, both from Duke University.

As the climate warms, sources of the water so critical to life everywhere on Earth are drying up.

By the end of this century, communities dependent on freshwater from mountain-fed rivers could see significantly less water, according to a new climate model recently released by University of California researchers.

For example, people who get freshwater from the Kings River could see a 26 percent decrease in river flow.

Extreme changes in seasonality in the Sierra Nevada can have lasting impacts on meadow health and could mean less water and carbon storage in high elevation wetlands, according to research conducted at UC Merced.

The National Science Foundation is honoring UC Merced Professor Asmeret Asefaw Berhe with a Faculty Early Career Development Award to support her examination of how soil helps regulate the climate.

The awards are given to junior faculty members who “who exemplify the role of teacher-scholars through outstanding research, excellent education and the integration of education and research within the context of the mission of their organizations,” the NSF said.

The environment affects the way genetic populations move, and similar environments likely play a bigger role in how a species develops than does geographic distance.

Those are just two of the discoveries Professor Jason Sexton has made while studying the monkey flower, a California native that is practically in his back yard, now that he has joined UC Merced.

Two researchers from the University of California, Merced, are slated to take part in the UC Drought Science, Policy and Management Summit at the state Capitol this week.

In a megadrought like the one California is experiencing, people tend to look at how much rainfall has come along.

But it also matters when the snowmelt releases its cache, because the snowpack is the state’s natural reservoir.

Large, naturally occurring low-oxygen zones in the Pacific appear to be expanding, and there is a sharp change in the number of bacteria that produce and consume different forms of toxic sulfur, according to a UC Merced researcher’s latest paper in Nature Communications.

These expanding deoxygenated zones could also contribute to climate change, which, in turn, appears to contribute to their growth.

The protected land adjoining the northeast corner of campus is officially part of the UC Natural Reserve System now that the UC Board of Regents gave the proposed reserve final approval today at its January meeting.  

The Merced Vernal Pools and Grasslands Reserve is the 39th reserve in the statewide system, adding more than 6,500 acres to the more than 750,000 acres already being conserved and studied. UC Merced’s reserve, though, is the first one in the San Joaquin Valley, and the first one in the heart of the greater Central Valley.
