Millions of years in the making, California’s unique animals roam a variety landscapes, national and state parks, our towns, neighborhoods and even our own backyards. Researchers are tracking changes to wildlife populations and what that means - from starfish and Sierra sheep to bears and beetles.

California is also home to some of the largest populations of domestic animals in the country. UCANR works with these working animals to produce our food sustainably.

Learn about how the UC is always working to keep our wildlife wild and our farm animals healthy.

The largest non-commercial marine mass mortality event on record (as of 2013) created a 'natural experiment' and an opportunity to study genomic changes in wild populations with unprecedented detail. Rather than observing only the aftermath a team of researchers from UC Merced is reconstructing the population and genetic consequences of an epidemic outbreak of sea star wasting disease. The team measured the abundance and genetic variation of Pisaster ochraceus, a keystone species, in the year preceding mass mortality. They then repeated sampling of adults and juveniles in subsequent years, measuring population dynamics and genomic shifts during and after the disease outbreak. At a time when marine diseases and mass mortalities are on the rise, this study documents the impact of little-known wildlife diseases and potential trajectory of recovery in a keystone marine species.
