The bacterium Xylella fastidiosa is quarantined as a harmful organism and has already caused economically significant lethal diseases of grapevine, citrus, plum, peach, almond, oak, oleander, and numerous forest tree species in the Americas.
Historical California vegetation data that more than once dodged the dumpster have now proved their true value, documenting that a changing forest structure seen in the Sierra Nevada has actually happened statewide over the past 90 years.
An analysis of 727 mass die-offs of nearly 2,500 animal species from the past 70 years has found that such events are increasing among birds, fish and marine invertebrates.
A research team led by UC Berkeley ecologist Henry Streby discovered that birds in the mountains of eastern Tennessee fled their breeding grounds one to two days ahead of the arrival of powerful supercell storms.
A new study representing a collaboration across several ESPM lab groups has found that organic farming is much more productive than commonly perceived.
A new international research review led by UC Berkeley says the debate over fuel-reduction techniques is only a small part of a much larger fire problem.
A new study by ESPM postdoctoral researchers Daniel Karp and Leithen M'gonigle, and professor Claire Kremen, highlights just how dramatic the evolutionary diversity of wildlife is affected when forests are transformed into agricultural lands.
A new study by biologists at Stanford University and UC Berkeley highlights the dramatic hit on the evolutionary diversity of wildlife when forests are transformed into agricultural lands.
A conservation biologist at the University of California, Berkeley, is giving important guidance in the efforts to rescue Devils Hole pupfish by establishing a captive breeding program.
Global decline of wildlife populations is driving increases in violent conflicts, organized crime and child labor around the world, according to a new policy paper led by UC Berkeley researchers.
Sudden Oak Death (SOD), a serious exotic disease, is threatening the survival of tanoak and several oak species in California. Community volunteers can help by collecting and submitting leaf samples for DNA-based analyses.
The California drought is helping save the state's signature tree - the mighty oak - by slowing down the spread of the plague-like disease scientists call sudden oak death.
California's winter tule fog has declined dramatically over the past three decades, raising a red flag for the state's multibillion dollar agricultural industry, according to researchers at the University of California, Berkeley.
A new study by UC Berkeley researchers and international collaborators finds that policies to support sustainable cattle ranching practices in Brazil could put a big dent in the beef and food industry’s greenhouse gas impact.
Ohio State University researchers have developed a way to predict the resistance or susceptibility of trees to sudden oak death disease, providing forest managers with the first effective method to manage trees in infested natural areas and in adjoining areas where the disease is expected in the future.
Over the next five years, UC Berkeley scientists will study the Eel River watershed in Northern California. What they uncover will help improve global climate models and modeling tools that can be used by state or regional decision makers to guide planning.
Calcium can do much more than strengthen bones. The mineral is a critical nutrient for healthy tree growth, and new research shows that adding it to the soil helps reverse the decades-long decline of forests ailing from the effects of acid rain.
Low-income neighborhoods are more often exposed to poor environmental quality when compared to wealthier communities, and scientists are saying this gap will increase as climate change is more widely felt.
Public health and environmental science professor Rachel Morello-Frosch has found that minorities are more likely to live in "urban heat islands" and are most at risk during heat waves.
In the largest U.S. atmospheric chemistry field project in decades, researchers sponsored by the National Science Foundation (NSF) and other organizations are working to study tiny particles and gases in the air over the southeastern United States.
