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.

At the northern tip of the UC Merced campus, an unremarkable aluminum gate leads into a field that extends, seemingly, into infinity. Perpendicular to the gate, the LeGrand Canal, drawn from Lake Yosemite, snakes around campus into the emerald pastures, through farm rows and almond orchards across the highway. It’s the rainy season and bulbous cumuli foreground the rippled line of the Sierra Nevada that slices across the open sky.

Three big UC Solar projects are poised to be the next big breakthroughs in low-cost, accessible sustainable commercial and residential energy in California and far beyond.

Researchers are building working models of one project developed through a grant from the California Energy Commission for a solar unit that can provide electricity and heat to commercial and residential buildings.

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.

Conservation and leadership of the country’s national parks and natural resources is ingrained in the UC Merced’s DNA. To reinforce the concentrated efforts surrounding sustainability of the nation’s gems, the university recently hosted its prestigious National Parks Institute Executive Leadership Seminar.

Graduate student Vicky Espinoza shared the plight of some San Joaquin Valley families with a wide audience this spring in her role as a Next Generation delegate to this year’s Chicago Council on Global Affairs Global Food Security Symposium, entitled “From Scarcity to Security: Managing Water for a Nutritious Food Future.”

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.

UC Merced’s Graduate Division will host its Grad Slam competition on April 18 with graduate scholars presenting on topics ranging from Valley Fever immune response and antibiotic resistance to computer vision and mathematical methods for thermal collection. This year’s competition started in March with 30 graduate students in the qualifying round, from which the judges narrowed the field to the top 12.

The campus’s 2019 Grad Slam semi-finalists are:

Children who live near major roads are at higher risk for developmental delays because of traffic-related pollutants.

That’s the major finding of a new study authored by UC Merced environmental epidemiology Professor Sandie Ha and colleagues. The study appears in the journal Environmental Research and is funded by the National Institutes of Health (NIH) and the UC Merced Senate Grant.
