Two isolated mountain lion populations in Southern California’s Santa Ana and Santa Monica Mountains are at risk of local extinction, perhaps as soon as within 50 years, according to a study published in the journal Ecological Applications. For the study, lead author John Benson of the University of Nebraska and co-authors at UCLA, UC Davis, the National Park Service, the University of Washington, Northern Arizona University, and the University of Wyoming used population viability modeling to predict the possibilities of extinction from genetic and demographic risk factors. The extinction risk is due to low genetic diversity and mortality that affects the stability of the population. But increasing connectivity could help.

Pandemic Engineering: Tools for Lowering Risk and Spread of Infection
UC Davis's dean of engineering, Richard L. Corsi, Ph.D., P.E., is an internationally recognized expert in the field of indoor air quality, with a specific interest in physical and chemical interactions between pollutants and indoor materials. Corsi discusses "pandemic engineering" and approaches to disrupt transmission by reducing the inhaled dose of respiratory aerosols, including the highly effective and relatively low-cost do-it-yourself air cleaner for respiratory aerosols that has become known as the "Corsi-Rosenthal box."

How Agricultural Innovations Help Feed the Future In Cambodia
Farmers in Cambodia have started to grow more vegetables to meet rising consumer demand, supported by innovations from a team led by UC Davis researchers. With help from Cambodia’s Royal University of Agriculture, farmers adopted "nethouses" to protect crops from pests without the use of chemical pesticides and packinghouses to better care for their crops after harvest.

Knights Landing - Community Garden
Knights Landing is a small, rural community just north of Davis, CA. With little access to a local grocery store, volunteers from UC Davis helped complete a community garden so they can grow their own fresh produce. Series: "UCTV Prime" [Agriculture] [Show ID: 37405]
