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.

“The Delta is sort of the heart and lungs of Northern California,” said O’Day, a geochemistry professor, founding faculty member and former chair of the Department of Life and Environmental Sciences in the School of Natural Sciences.

Breakthrough collaborative science by an interdisciplinary team of researchers brought together by computational biology Professor David Ardell promises a new approach for treating all types of infections.

Infections have become more dangerous in recent years because bacteria and parasites rapidly evolve resistance to the medicines.

Even a little forest management significantly increases water runoff in the Central Sierra Nevada and other semi-arid regions, while drier forests need more extensive treatments, according to a new study published recently in the journal Ecohydrology.

“The result is more runoff to downstream water users,” said UC Merced Professor Martha Conklin , who led the study.

Soil is one of the foundations of life on Earth and could be an important part of the solution to climate change, if only we can stop treating it like dirt.

The most extreme drought event in hundreds of years caused a catastrophic die-off of the Sierra Nevada’s mature trees in 2015-2016.

A study published today in Nature Geoscience details how UC Merced Professor Roger Bales and his colleague Professor Michael Goulden from UC Irvine tracked the progress of the devastation caused by years of dry conditions combined with abnormally warm temperatures.

Climate change is bad news for forests, and a new study by UC Merced Professor Emily Moran demonstrates one aspect of that news.

Higher summer temperatures hurt tree seedlings’ growth and survival.

But whether that is entirely bad depends on the degree of change in the number of young trees.

A nine-year experiment by a UC Merced Department of Life and Environmental Sciences professor and his colleagues is illuminating the importance of soil carbon in maintaining healthy and functioning ecosystems because of its influence on the microbial communities that live in soil.

These communities’ health can help researchers understand the effects of climate change.

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.
