Soils are carbon sinks, storing more planet-warming carbon than the atmosphere and all animal and plant life combined.

But they can also release massive amounts of stored carbon into the atmosphere. Given carbon’s central role in climate change, understanding the forces that govern how soils absorb and release carbon is crucial.

The National Academies of Sciences, Engineering and Medicine (NASEM) just announced that they’ve selected Professor Asmeret Asefaw Berhe to serve as an inaugural member of the Academies’ newest initiative — New Voices in Sciences, Engineering and Medicine (SEM).

There are too many trees in Sierra Nevada forests, say experts from UC Merced, UC Irvine and the National Park Service working at the National Science Foundation Southern Sierra Critical Zone Observatory (NSF SSCZO).

This comes as a surprise to those of us who see dense, verdant forests as a sign of a healthy environment. After all, green is good, right? Not necessarily. When it comes to the number of trees in California forests, bigger isn’t always better.

April is Earth Month. It’s also when UC Water Academy — an intensive course aimed at training the next generation of California water experts — starts its second year.

For the first time, UC Merced’s doctoral programs in the sciences have been ranked among the best in the nation, according to U.S. News & World Report’s 2019 edition of Best Graduate Schools.

A new study published online in the Journal of Geophysical Research: Biogeosciences finds that the giant sequoia, a fixture of California’s Sierra Nevada forests for the past 2.6 million years, might be in jeopardy from the effects of drought and climate change.

A team of UC Merced researchers was recently awarded $100,000 from Pacific Gas and Electric Company (PG&E) to identify ways to improve drought resilience and reduce the risk of wildfire in Sierra Nevada forests.

Professor Asmeret Asefaw Berhe is a biogeochemist who studies the impact of climate change on Sierra Nevada soils. She’s also active in efforts to recruit and retain women in science, technology, engineering and math (STEM).

Scientists from the Sierra Nevada Research Institute, UC Merced, UC Berkeley and the USDA Agricultural Research Service have designed the first ever wireless sensor network (WSN) capable of accurately monitoring the hydrology of large mountain river basins.

Subalpine meadows are among the Sierra Nevada’s most enchantingly picturesque landscapes.
