A new study in Science led by Santiago Ramirez , post-doctoral researcher in theTsutsui Lab, has found that the orchid bee evolved at least 12 millions years earlier than the orchid.
Orchid bees aren’t so dependent on orchids after all, according to a new study that challenges the prevailing view of how plants and their insect pollinators evolve together.
Professor Damian Elias identifies the cause of sounds made by some hummingbird species during courtship.
Professor Peng Gong and PhD student Iryna Dronova are applying remote sensing, GIS, and field surveys to study the seasonal variation in plant functional types that not only provide critical habitat but are key players in Poyang lake’s biogeochemical cycles.
PhD student Sheri Spiegal and the Range Ecology Lab, under the leadership of Professor James Bartolome, are measuring vegetation change across space and time in Tejon Ranch’s grasslands and isolating environmental factors driving the change.
UC Berkeley and the Italian National Research Council showed that the pathogen responsible for cypress canker disease, has lived and thrived in California for a long time.
Getz lab member Steve Bellan is looking at how the behavior of scavengers, like the black-backed jackals, contributes to the dynamics of infectious diseases.
Steve Bellan, a Ph.D. student in the Getz Lab, uses a combination of dynamic modeling and field work to gain insight into how host movement and social behavior contribute to the epidemiologic dynamics of infectious diseases.
UC scientists built and worked in towers as part of the largest single atmospheric research effort in the state. The data they've collected will guide policymakers dealing with air pollution.
Graduate student Sarah Reed of the Amundson Lab, studies the exchanges and feedbacks between terra firma and the organisms that move and live within it.
Graduate student Thomas Azwell's research focuses on a better understanding of the environmental impacts of oil spills and innovating better technologies for oil spill response, remediation and restoration.
Graduate student Erica Spotswood's research investigates how the introduction of non-native frugivores and fruit-bearing plants on oceanic islands has altered seed dispersal relationships between birds and plants.
The Blodgett Forest Research Station in the Sierra Nevada mountains is part of a study designed to find out how trees respond to different levels of competition for resources (light, water, and nutrients).
Professor Li Wenjun of Peking University and Professor Lynn Huntsinger of ESPM have collaborated on studies of the impacts of policies that seek to reduce sand storms and improve the lives of herders in Inner Mongolia.
ESPM professor George Oster and colleagues presented a model to explain how the diversity of shell shapes and patterns amongst the marine mollusks arise from the neural net in their mantle—the secretory organ that constructs and paints the shell.
ESPM scientist Ronald Amundson and his colleagues are using field research and chemical techniques to determine how old the desert is, how the landscape has evolved during millions of years of near-lifelessness, and how microbial life has adapted to these harsh conditions.
A paper reviewing the impact of the loss of large predators and herbivores high in the food chain confirms that their decline has had cascading effects in marine, terrestrial and freshwater ecosystems throughout the world.
Graduate student Erica Spotswood used data from organisations across the United States and Canada to assess the risk factors which could increase rates of injury or mortality including bird size, age, frequency of capture and the role of predators.
Researchers found that across all eight counties studied, there was a positive correlation between water systems that served larger proportions of Latinos and increased nitrate levels in the water systems.
California agriculture reaps $937 million to $2.4 billion per year in economic value from wild, free-living bee species that serve the critical function of pollinating crops.
