Research Description

David Ackerly is a climate change biologist and professor in the departments of Integrative Biology and Environmental Science, Policy, and Management and Dean of the Rausser College of Natural Resources at UC Berkeley. Ackerly’s research group studies the impacts of climate change on biodiversity in California, and post-fire forest dynamics in mixed hardwood and oak woodlands. He has focused on the importance of spatial climate heterogeneity at landscape and regional scales to enhance resilience and facilitate range shifts for native plants and animals. Ackerly is a recipient of the 2011 Distinguished Faculty Mentor Award, a Senior Fellow with the Berkeley Institute of Data Sciences, a Fellow of the California Academy of Sciences, and a Fellow of the Ecological Society of America.

The Climate Crisis: Justice and Solutions

Despite the grim findings of the latest U.N. Climate Report, UC Berkeley associate adjunct professor and report lead author Patrick Gonzalez expresses a “science-based optimism” about humanity’s ability to cut carbon emissions and limit the worst projected impacts of climate change.

As global climate shifts, forests’ futures may be caught in the wind

Forests’ ability to survive and adapt to the disruptions wrought by climate change may depend, in part, on the eddies and swirls of global wind currents, suggests a new study by researchers at the University of California, Berkeley. The findings are the first to show that wind may not only influence the spread of an individual tree or species’ genes, but can also help shape genetic diversity and direct the flow of gene variants across entire forests and landscapes.

Climate change and COVID-19: Can this crisis shift the paradigm?

Ever so slowly, communities around the globe are cautiously easing shelter-in-place orders, and people are heading back to work — bringing with them damaging behaviors that hurt the environment and impact climate change, such as increased reliance on single-use plastic grocery bags.

UC Berkeley, Jerry Brown launch new pan-Pacific climate institute

UC Berkeley, in partnership with former California Gov. Edmund G. Brown Jr. and China’s top climate change official, Xie Zhenhua, today (Monday, Sept. 23) announced the launch of a new campus institute to bring together top researchers and policymakers from both sides of the Pacific to stop the rise of greenhouse gases.

UC Berkeley leads new assessment of Bay Area climate impacts

California today issued its latest assessment of the many challenges the state faces from climate change — including wildfires like those still raging throughout the state – and highlighted for the first time the regional impacts with nine deep-dive reports spearheaded by University of California scientists.

Deploying drones to follow the water

Drones will play a key role in assessing the impact of highly variable water resources around the state thanks to a new $2.2 million grant from the Gordon and Betty Moore Foundation.

Forecasting Change, Welcome or Not

Plant ecologist David Ackerly has calculated that some animals and plants would need to migrate as much as four miles a year to track their preferred temperature in a rapidly warming climate. 

Warmer, drier climate altering forests statewide

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.

Scientists enlist big data to guide conservation efforts

Despite a deluge of new information about the diversity and distribution of plants and animals around the globe, “big data” has yet to make a mark on conservation efforts to preserve the planet’s biodiversity. But that may soon change.

Climate change puts ecosystems on the run

To keep up with global warming, the average ecosystem will need to shift about a quarter mile each year, says a new study by scientists at Stanford University and the University of California, Berkeley.
