A rigorous, first-of-its-kind global study provides new insights into the natural history of soil biodiversity and shows that changes in soil pH during soil development is a major driver of most of that biodiversity.

Climate change is having a profound effect on the millions of migrating birds that rely on annual stops along the Pacific Flyway as they head from Alaska to Patagonia each year.

They are finding less food, saltier water and fewer places to breed and rest on their long journeys, according to a new paper in Nature’s Scientific Reports.

A $4.6 million grant to UCs Merced and Irvine will help researchers develop new tools and methods for better managing the state’s forests, shrub lands and grasslands.

UC Merced researchers have evidence that California’s forests are especially vulnerable to multi-year droughts because their health depends on water stored several feet below ground.

The Earth is changing, and humans face major challenges if they hope to adapt, survive and preserve any semblance of the world as it is now.

Humans will need to create sustainable food, water and energy supplies; curb climate change; eliminate pollution and waste; and design efficient, healthy and resilient cities. To support these efforts, they will also need to enhance society’s ability and will to make informed decisions and act; and develop leaders who are prepared to address a sustainable future.

Civil and environmental engineering Professor Erin Hestir’s proposal for a unique system of mapping mercury in the waters of the San Francisco Delta has won her and her team of collaborators a $1.7 million grant from the California Department of Fish and Wildlife (CDFW).

Paleoecology Professor Jessica Blois recently became the campus’s 19th recipient of the National Science Foundation (NSF) Faculty Early Career Development Program (CAREER) award.

The NSF describes as the CAREER as its “most prestigious award in support of early-career faculty who have the potential to serve as academic role models in research and education and to lead advances in the mission of their organizations.”

The award provides Blois with $782,449 over the next five years to pursue an agenda that includes research and outreach.

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.
