Developing Metrics to Evaluate the Skill and Credibility of Downscaling

Within the climate science community, a variety of techniques are used to "downscale" information from global climate models and produce fine-scale projections of future climate, but the relative strengths and weaknesses of these techniques are not well-understood. In this project, we are comparing downscaling techniques and establishing best practices.

distribution modeling using remote sensing

Distribution Modeling Using Remote Sensing

In this research, species distribution modeling is used as a tool to understand the environmental determinants that control the distribution of species and to obtain spatial patterns on the species’…

dja reserve

Dja Reserve

For the past 20 years, we have been conducting research in the Dja Biosphere Reserve and adjacent areas.  The Dja Biosphere Reserve is a UNESCO World Heritage site located in…

ebola

Ebola

The Center for Tropical Research is investigating what may be the environmental drivers of infectious diseases, and what might trigger outbreaks during particular times or conditions. In collaboration with Dr. Rick Schoenberg, chair of the the Department of Statistics at UCLA, our team is using novel models to understand ebola outbreaks.

eco-evolutionary consequences of global change on invasive plant species

Eco-Evolutionary Consequences of Global Change on Invasive Plant Species

Human activities are dramatically impacting ecosystems worldwide due to air pollution – and resulting changes to climate and nitrogen cycling – and the spread of nonnative plant species. These drivers of global change may have strong and interactive ecological effects, but the evolutionary impacts of these factors are poorly understood. La Kretz postdoc Justin Valliere is currently exploring potential adaptation to nitrogen pollution and climate in common invasive plant species of California. This study will have important implications for invasive plant management under predicted global change.

eco-labels and cleaning product attributes

Eco-labels and Cleaning Product Attributes

In this project, which was also a practicum project, we examine the preferences of consumers over different eco-label attributes for cleaning products. To accomplish this goal, we designed and implemented…

eco-labels and quality in wine

Eco-labels and Quality in Wine

Eco-labels are part of a new wave of environmental policy that emphasizes information disclosure as a tool to induce environmentally friendly behavior by both firms and consumers. Little consensus exists…

ecological impacts of nitrogen deposition on coastal sage scrub of the santa monica mountains

Ecological Impacts of Nitrogen Deposition on Coastal Sage Scrub of the Santa Monica Mountains

California’s native ecosystems are increasingly impacted by nitrogen deposition resulting from air pollution, particularly in the greater Los Angeles area. This project, led by La Kretz postdoc Justin Valliere, extends an ongoing collaboration between the National Park Service, the U.S. Forest Service and the UCLA, with the goal of understanding the ecological impacts of nitrogen pollution on the severely threatened coastal sage scrub plant community of the Santa Monica Mountains.
