Earth Systems Science

It has been 186 years since Charles Darwin collected the samples of the Galapagos Islands species that led to his explanation of how the diversity of life on Earth has evolved and forever changed the way we understand the world.

During his five-week stay on the islands, Darwin collected dozens of samples, including one small, light brownish-grey snake on Floreana Island. That sample, now at the Natural History Museum in London, was the basis for describing a new species, the Galapagos (Floreana) racer.

With a new $20 million federal grant, UC Merced becomes part of a multi-institutional research collaborative to develop artificial intelligence — or AI — solutions to tackle some of agriculture’s biggest challenges related to water management, climate change and integration of new technology into farming.

Scientists often study the relationship of global warming and topsoil because soil is an important mediator of climate change. A newly released study indicates it’s critical to consider subsoil in climate-change research, too.

President Joe Biden has nominated UC Merced Professor Asmeret Asefaw Berhe to be the new director of the Office of Science in the federal Department of Energy.

Black History Month may feel different this February, after a year of the coronavirus and historic protests for social justice. While coming together couldn’t be more important, under current conditions few are able to gather to celebrate Black History Month and the many contributions Black people have made to society. 

Two new projects designed and led by UC Merced researchers will address challenges facing many Californians — wildfire recovery and agricultural labor — but will also have global reach.

Soil biogeochemistry Professor Asmeret Asefaw Berhe has been recognized by the American Geophysical Union (AGU) as one of this year’s recipients of the Joanne Simpson Medal for Mid-Career Scientists.

Since 2007, UC Merced researchers have been extremely productive in the Southern Sierra Critical Zone Observatory (CZO), delving into investigations of hydrology, climate change, geology, biology and more.

But the National Science Foundation, which funded the CZOs, is decommissioning the sites and has reconfigured the program around themed research clusters in a new program called the Critical Zone Collaborative Network (CZCN).

The world is a complex place, and humanity faces major challenges. Climate change mitigation might be the most difficult, in large part because of the interdependency of living things and their ecosystems.

How do people transform economic systems so they are also sustainable for people and the planet?

“If we don’t consider how everything connects from a systems perspective, we’re not going to solve grand challenges such as climate change,” Professor Tracey Osborne said. “Not even close.”

There’s a whole world of activity beneath your feet. Soil holds a large proportion of Earth's biodiversity, and is the place where organisms interact with each other and with plants, serving important functions for their ecosystems.
