Key Points:

• Elephants function as a keystone species, producing large amounts of nutrient-rich dung that sustain diverse dung beetle populations and support wider ecosystem health.

• A 15-year field experiment showed that removing elephants leads to sharp declines in dung beetle abundance, biomass, and species diversity, and other herbivores cannot replace their role.

UC Merced is abuzz with celebration as students, families, friends, staff and faculty finish last-minute preparations for the largest commencement in university history.

Across three outdoor ceremonies, 1,649 undergraduates and 112 graduate students will walk the stage at Spring Commencement 2026, marking a record-setting milestone for the university. This year’s celebrations are especially meaningful as the university awards its 1,000th Ph.D., highlighting just how far the institution — and its graduates — have come.

Students who arrive at UC Merced planning on specific careers often discover along the way that their interests — and strengths — are broader than they first imagined.

A new initiative called Education Tracks, or EdTracks, is designed to give students a flexible, low‑risk way to explore careers in education without delaying graduation or adding significant cost.

Avinav Biswas, a third‑year undergraduate majoring in biological sciences at UC Merced, has been named a 2026 Barry M. Goldwater Scholar, becoming the university’s first recipient of one of the nation’s most prestigious undergraduate awards for students pursuing research careers in science, engineering and mathematics.

The scholarship provides $7,500 annually to support tuition, fees, books and living expenses. It is awarded to students who demonstrate exceptional research achievement and promise, and who plan to pursue careers centered on scientific discovery.

Professors Asmeret Asefaw Berhe and Ming-Hsuan Yang have been named 2025 fellows of the American Association for the Advancement of Science, the world’s largest general scientific society and publisher of the Science family of journals.

They are among the nearly 500 scientists, engineers and innovators who have been recognized this year for their distinguished scientific and social achievements.

UC Merced’s CalTeach program is opening new pathways for younger students to experience hands-on science, technology, engineering and math (STEM) learning, academic support and early exposure to a college environment.

On most days, Reo Maynard’s life swings between two ecosystems: the microscopic world inside an ant’s gut and the sprawling one that stretches from Fresno to the Sierra Nevada mountains.

The 51-year-old Navy veteran, dad of two, screenwriter-in-waiting and newly minted Fresno City College faculty member is in his eighth year at UC Merced, earning his Ph.D. in Quantitative Systems Biology.

“I’ll be defending in May. The end is here,” he said, with the equal parts relief and wonder of someone who kept moving when the ground shifted beneath him.

Although the oceans are the least explored places on the planet, even their depths are not untouched by humans.

Drawing on more than 2,300 seawater samples collected across the Pacific, Atlantic and Indian Oceans, researchers found that hundreds of synthetic chemicals — many of them rarely monitored and originating from everyday products — are now woven into the fabric of marine organic matter.

Our circadian clocks play a crucial role in our health and well-being, keeping our 24-hour biological cycles in sync with light and dark exposure. Disruptions in the rhythms of these clocks, as with jet lag and daylight saving time, can throw our daily rhythms out of whack.

But a group of researchers is getting closer to understanding how these clocks operate.

UC Merced biochemistry Professor Andy LiWang and his colleagues have solved how the circadian clocks in microscopic bacteria precisely control when different genes are turned on and off during the 24-hour cycle.

Biochemistry Professor Andy LiWang has spent much of his career studying how life keeps time. His work on the circadian clock of cyanobacteria — tiny, ancient organisms that share the planet with us — has shed light on one of biology’s most elegant systems.

But his newest research project, supported by a prestigious $1.2 million grant from the William M. Keck Foundation, pushes that inquiry into bold, uncharted territory.
