A few miles south of Yosemite’s famed Glacier Point, ringed by striking granite domes, lies the Illilouette Basin. This small stretch of the Sierra Nevada Mountains has become a sort of fire laboratory, a place where natural wildfires have been allowed to burn since 1972. In contrast with the long-supported program of fire suppression that has dominated American forests since the late 19th century, resulting in dense and unhealthy forests, the Illilouette Basin’s story is about the benefits that natural fire can bring to the landscape.
Groundwater is Key to Protecting Global Ecosystems
New research identifies ecosystems around the world that could be threatened by declining groundwater levels. The research, published July 17 in Nature, is the first time that groundwater-dependent ecosystems have been mapped on a global scale. Led by scientists from The Nature Conservancy and DRI, the global effort brought researchers together from universities, non-profit organizations, and institutions from seven countries.
River ‘Plastisphere’ Serves as Home to Ecosystem-Draining Organisms
New research explores the microbial communities that live on plastic waste and how they impact the 2nd most biodiverse river in the world. DRI researchers Monica Arienzo and Rachel Kozloski are co-authors on this new study that examines the ecological impacts of plastic waste in Cambodia’s Mekong River.
Western Agricultural Communities Need Water Conservation Strategies to Adapt to Future Shortages
Relying on water storage won’t be enough to make up for declines in future water availability under a changing climate, new study shows. Beatrice Gordon, lead author of the study and sociohydrologist and postdoctoral researcher at DRI, says the research is needed to inform water management at the local level, where most decisions are made.
New Study Estimates Lithium in Groundwater That Can Be Used for Drinking Water
DRI researchers Monica Arienzo and Daniel Saftner are coauthors on a new study led by the USGS that examines lithium levels in groundwater aquifers used to supply drinking water across the U.S. The new estimates can help health researchers determine potential connections between lithium exposure and human health outcomes.
Every Drop Counts: New Algorithm Tracks Texas’s Daily Reservoir Evaporation Rates
A recent collaboration between DRI and Texas A&M University researchers provides state of the art, real-time evaporation estimates for improved management of water supply reservoirs throughout Texas.
Rising Temperatures Will Significantly Reduce Streamflow in the Upper Colorado River Basin As Groundwater Levels Fall, New Research Shows
Climate change will dramatically impact streamflow and its contributions to the Colorado River by increasing forest water use and reducing groundwater levels, new study finds.
New Method Reveals Hidden Activity of Life Below Ground
DRI’s Duane Moser, Ali Saidi-Mehrabad, and Molly Devlin co-authored a new study that examines the genetics and life strategies of microbes living deep below Earth’s surface. Dr. Moser and his lab conducted the fieldwork for the research as part of their work studying deep wells located in the Death Valley regional flow system.
DRI’s Christine Albano Co-authors Groundbreaking New Research in Groundwater’s Role in Ecosystem Sustainability
A new study published in Nature Water used satellite data spanning 38 years to examine how groundwater-dependent ecosystems (such as wetlands, meadows, and springs) in California respond to fluctuations in groundwater levels. The research can help shed light on how water management practices can best account for ecosystem needs in addition to those of human society.
A Fresh Look at the Drivers of Extreme Flooding
A new study in Science Advances finds that compounding effects of flood drivers can complicate and exacerbate the risk of extreme floods in watersheds around the world. DRI’s Guo Yu, Ph.D., assistant research professor of hydrometeorology, co-authored the research.
