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.

Most people wouldn’t think sharks can teach researchers about the planet’s distant past and its more immediate future.

UC Merced paleoecologist Professor Sora Kim isn’t most people.

There’s a connection between data in fossilized shark teeth and climate change, and thanks to a grant from the National Science Foundation, she aims to use that information to better understand climate change.

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.

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.

Forty million years after dinosaurs went extinct, one of the largest predators that ever prowled Earth’s oceans emerged, feeding the imaginations of modern scientists and the nightmares of modern movie audiences.

Megalodon — the name means ‘giant tooth’ — appeared some 23 million years ago and reigned the seas for about 21 million years. In 400 million years of shark evolution, megalodon is the most massive shark species that ever lived, growing to 60 feet long, or three times the size of the largest of today’s great whites.

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).

California aims to lead the nation — and the globe — in climate change research, policy and action — in large part through climate-focused research conducted at University of California campuses and labs.

Some of that research, including from UC Merced, will be on display this week as climate-change scientists, policymakers and trailblazers from around the globe gather in San Francisco for the 2018 Global Climate Action Summit .
