Scientists have identified more than 35 new groups of bacteria, clarifying a mysterious branch of the tree of life that has been hazy.
Steadily and alarmingly, humans have been depleting Earth's soil resources faster than the nutrients can be replenished.
Efforts to predict the emergence and spread of sudden oak death, an infectious tree-killing disease, have gotten a big boost from the work of grassroots volunteers.
A new study by Professor John Battles and collaborators at the National Park Service quantifies the amount of carbon stored and released through California forests and wildlands.
The existence of ultra-small bacteria has been debated for two decades, but there hasn’t been a comprehensive electron microscopy and DNA-based description of the microbes until now.
The similarity between vineyard landscapes in Chile and California is striking: both lie in mediterranean-climate ecosystems made up of twin vegetation types, and both produce some of the world’s best wines.
At the Rocky Mountain Biological Laboratory, the scientists have monitored ten 30-square meter plots of meadowland since 1989.
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.
