For the past five years, Goabaone Jaqueline Ramatlapeng, a National Geographic Explorer and UC Davis earth and planetary sciences doctoral candidate, has studied the water chemistry of the Okavango Delta, the largest freshwater wetland in southern Africa. Recently, she received $100,000 from the National Geographic Society to further her research.
While so much of the ocean is still a mystery to us, the beauty and life within it are being affected by our choices as a species. In some ways, its' changing faster than we can study them. In the book “At Every Depth,” UC Davis scientist Tessa Hill and writer Eric Simons chronicle those changes through the eyes of the community members closest to the shores. But the book is not a passive volume. Instead, it’s a call to action.
You don't have to be a student at UC Davis to learn from these professors. Their knowledge about Earth and its environment is woven throughout these new books, including two from College of Letters and Science faculty, that came out in 2023 or are about to be published.
Paleontologists are getting a glimpse at life over a billion years in the past based on chemical traces in ancient rocks and the genetics of living animals. Research published Dec. 1 in Nature Communications combines geology and genetics, showing how changes in the early Earth prompted a shift in how animals eat.
Shellfish, along with other marine organisms, are facing a crisis, one that affects the
integrity of their shells. As carbon dioxide emissions increase in the atmosphere, so too
does the amount of carbon dioxide absorbed by our oceans, leading to ocean
acidification. Graduate student Meghan Zulian has devoted her doctoral studies to
understanding how ocean acidification, and more broadly climate change, affects
culturally, economically and ecologically important shellfish, including abalone
Over the course of her career, Distinguished Professor Isabel Montañez has created a
research niche in the fields of geochemistry and paleoclimatology: applying an Earth
systems science approach to recreate Earth from eons past. For her monumental work
in the geology field, Montañez recently received the Geological Society of America’s
Arthur L. Day Medal.
As we reckon with the effects of climate change, so too must the other organisms that
call Earth home. But what if you couldn’t move away from your dwelling to escape a
threat? What if your shelter, your refuge, was a part of your body? Shellfish face this
plight. Supported by an $80,000 California Sea Grant Graduate Research Fellowship,
UC Davis doctoral candidate Hannah Kempf is exploring how to unify modern scientific
techniques with Indigenous shellfish management practices to help protect shellfish
from ocean acidification.
Violence during climatic change has evidence in history. University of California, Davis, researchers said they have have found a pattern of increased violence during climatic change in the south central Andes between A.D. 470 and 1500. During that time, which includes the Medieval Climatic Anomaly (ca. A.D. 900-1250), temperatures rose, drought occurred, and the first states of the Andes collapsed.
Caden Williams is among 413 college students nationwide selected from a pool of more than 5,000 applicants to receive the prestigious STEM scholarship, which was established by Congress in 1986 to honor the late U.S. Sen. Barry Goldwater. The award provides up to $7,500 for college expenses. This is the sixth consecutive year that a UC Davis student has been named a Goldwater Scholar.
People often say things like Phoenix has always been dry; Seattle has always been wet; and San Francisco has always been foggy. But “always” is a strong word. A study from the UC Davis Department of Earth and Planetary Sciences synthesizes climate trends across the Western U.S. during a relatively young and lesser-studied period of Earth’s history — the Holocene Era, which stretches from the present day to the past 11,000 years.
