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.
In 2006, California voters approved Proposition 84, a bond measure authorizing $5.4 billion in spending on projects to improve parks, natural resource protection, and water quality, safety, and supply. Most…
Current rates of species extinction exceed the evolutionary background rate, and some biologists claim we are witnessing the sixth mass extinction in the history of life on Earth. Imagining Extinction…
La Kretz Postdoc John Benson's work suggests that a new immigrant lion every two to four years is necessary for the Santa Monica Mountains population to remain viable
The Water Hub is a dynamic visualization and mapping platform (http://waterhub.ucla.edu); an online data repository for viewing and finding water-related information in Los Angeles County.
The Center for Tropical Research has recently developed new models in California to determine the amount of intraspecific genetic variation present in an area. Recently, we tested this new approach in the Santa Monica Mountains National Recreational Area (SMNRA), part of the southern subunit (2) of the California Landscape Conservation Cooperative.
With the imminent revitalization of the L.A. River, the city’s landscape is about to transform. But how will the restoration project impact life in and around the river?
The recent discovery by UCLA Center for Tropical Research (CTR) scientists that the large-bodied frugivorous hornbills (Ceratogymna sp., Fig. 1) of Central Africa make long-distance movements (Fig. 2) highlights their…
Coastal wetlands are among the most vulnerable ecosystems on the planet. Pressured in many cases by human development from the land, they also now face pressures due to sea level…
The Partnership for International Research and Education project seeks to develop an
integrated framework for conserving central African biodiversity under climate change that is both evolutionary-informed and grounded in the socioeconomic constraints of the region.
