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.

UC Davis Professor Hugh Safford was hiking for pleasure in California’s High Sierra when he stumbled upon a new elevation record for the Jeffrey pine, which may now be the state’s highest-altitude tree. His serendipitous finding is published in Madroño, a journal of the California Botanical Society.

On the shores of Lake Tahoe at Emerald Bay State Park grows what some consider to be the most iconic old-growth forest in the Lake Tahoe Basin. Giant ponderosa pines — some of the last remaining in the area — share space with at least 13 other tree species.

During Bilegt Baatar’s time in the Environmental Policy and Management (EPM) graduate program at UC Davis, he worked on a project that explored meaningful solutions for rural communities. He was part of a student team that analyzed gaps in electric vehicle infrastructure in non-urban areas and developed policy recommendations to address these challenges. Years later, Baatar was excited when a regulatory department cited his team’s work.

As their traditional dining options dwindle and natural areas give way to restaurants, homes and sidewalks, the coyotes of San Francisco are shifting what they eat.

Scientists from the University of California, Davis, wanted to understand what San Francisco’s coyotes are eating, and how their diet is changed and shaped by the city’s landscape, which can vary from block to block.

A ground squirrel with cheeks stuffed with nuts, seeds or grains, is a common sight. But a new study provides the first evidence that California ground squirrels also hunt, kill and eat voles. The study, led by the University of Wisconsin-Eau Claire and the University of California, Davis, is the first to chronicle widespread carnivorous behavior among squirrels.

The social cost of carbon — an important figure that global policymakers use to analyze the benefits of climate and energy policies — is too low, according to a study led by the University of California, Davis.

The University of California, Davis, Office of Research is pleased to announce the appointment of Stephanie Hampton as the director of the Tahoe Environmental Research Center (TERC) and professor in the Department of Environmental Science and Policy.

From coastal redwoods and Joshua trees to golden poppies and sagebrush, California is a global botanical hotspot. It’s also a place confronted with extreme heat, wildfires and crumbling coastlines. The state’s natural beauty and history of pioneering conservation efforts make it a test bed for protecting biodiversity in the face of current and future climate change, argues a study led by the University of California, Davis.
