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).

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.

It is said that rainforests are the Earth’s lungs, capturing carbon dioxide from the atmosphere, building it into lush vegetation and releasing oxygen and water back into the air.

When people think of engineering in nature, they tend to think of species such as beavers — the tree-felling, dam-building rodents whose machinations can shape the landscape by creating lakes and changing the path of rivers.

But beavers are far from the only organisms to reshape their environment. A squirrel that inadvertently plants oak trees is also an “ecosystem engineer.” Roughly speaking, any organism whose impact on the environment outlasts its own lifetime is an environmental engineer.

Wildfire seasons are intensifying because of climate change. That means reforestation efforts will increase, making it important for scientists and resource managers to understand how to make sure restorations will thrive in the future.

Every Fourth of July, the Carnegie Corporation of New York honors the legacy of its founder Andrew Carnegie, by recognizing an extraordinary group of immigrants, who are now naturalized American citizens, and who have made notable contributions to the progress of American society.

About 4.5 billion people around the globe do not have access to adequate sanitation, and what they do have — typically pit latrines and lagoons — are responsible for widespread illnesses and a portion of the greenhouse gases that are warming the planet.

UC Merced Professor Rebecca Ryals and a group of colleagues have a solution that not only increases safety, sustainability and jobs, but reduces greenhouse gas emissions and waste-borne illnesses while producing an effective fertilizer for agriculture.

UC Merced Professor Peggy O’Day hopes to improve water quality in the California Delta by studying local wetlands.

O’Day is leading a new three-year study of Merced County wetlands that drain into the San Joaquin River and eventually the Delta.
