California often swings between climate extremes — from powerful storms to punishing droughts. As climate change drives more intense and frequent dry and wet cycles, pressure on California’s water supplies grows.

A new University of California, Davis, economic study finds that drought in California pushes the price of water from rivers, lakes and reservoirs up by $487 per acre-foot, more than triple the cost during an average wet year. The research appears in Nature Sustainability.

A University of California, Davis research project that aims to improve maternal health for Black women, who face high rates of pregnancy-related complications, needs funding support to continue onto a vital next phase of the study.

Scientists at the University of California, Davis, have discovered a new species of trapdoor spider lurking in California’s coastal sand dunes. The newly identified Aptostichus ramirezae is a close relative of Aptostichus simus, a species found along the coast from Monterey to Baja California, Mexico.

A team of researchers from University of California, Davis, spent the summer at elementary schools across the state measuring tree canopies and just how hot playgrounds, basketball courts, soccer fields and other outdoor spaces can get.

A team of international researchers led by University of California, Davis, released a mobile tool recently that will help small-scale farmers in Asia and Africa craft the right diet for cattle to increase yield and productivity, helping to reduce methane emissions.

Demand for cattle milk and meat in Africa is growing each year. High costs for feed without adequate nutrients reduces productivity and contributes to emissions of methane, a potent greenhouse gas.

Siblings are special. Be they protector or tormentor, friend or foe, the relationship between siblings is like no other. They witness each other’s childhoods — sharing parents, history, secrets and advice.

Even among some bird species, siblings can be powerful role models — eclipsing even their parents’ influence — according to a study from the University of California, Davis, and the Max Planck Institute of Animal Behavior.

As the climate warms and nutrient inputs shift, algal communities in cool, clear mountain lakes like Lake Tahoe will likely experience seasonal changes, according to a study from the University of California, Davis.

Periphyton, that fuzzy layer of attached algae covering the rocks as you step into the water, is a healthy and critical part of a lake’s food web. Periphyton blooms, however, signal changes that can degrade both water quality and a shoreline’s natural beauty.

Three professors in the College of Agricultural and Environmental Sciences at UC Davis have taken on new roles on the college leadership team, Dean Ashley M. Stokes announced.

Professor Jason Bond is the new executive associate dean, or EAD, after serving on an interim basis in that position for several months. Professor Anne Todgham is the new associate dean for agricultural sciences and Professor Amanda Guyer is associate dean for human and social sciences.

For every juicy tomato or crunchy almond California grows, there’s a pile of pulp, hulls or scraps that often goes to waste. A new online tool, created by University of California, Davis researchers, tracks those agricultural byproducts aiming to find innovative ways to put them to use.
