Sea Star Wasting Disease Update 2017

32822The years from 2013 through 2015 witnessed the largest non-commercial marine mass mortality event on record (as of 2013) as up to 96% of all Ochre Sea Stars on the coasts of California and Oregon perished. This created a ‘natural experiment’ and an opportunity to study genomic changes in wild populations with unprecedented detail. Rather than observing only the aftermath — usually the case in such catastrophes – a team of researchers from UC Merced is reconstructing the population and genetic consequences of this epidemic outbreak of sea star wasting disease. The team measured the abundance and genetic variation of Pisaster ochraceus (the Ochre Sea Star – 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.

UCTV Launches New Portal to Sustainability for California

8232As the world’s sixth largest economy and provider of more than half the nation’s fruits, nuts, and vegetables, sustaining California’s vitality is paramount. And, with greater demands from a changing climate and growing population, taking a proactive approach to maintaining sustainable growth for California is critical.

That is what Sustainable California, a new, media-rich web portal hosted by University of California Television (UCTV) is about.

Broadcasting stories of sustainability research and outreach conducted by University of California faculty, scientists and students, Sustainable California
connects users to the science-based, real-world solutions the University of California is creating to maintain the balance of natural resources, biodiversity and sustainable growth in our state.

Principal project partners include UC Water, UC Agriculture and Natural Resources, CITRIS and the Banatao Institute, the Sierra Nevada Research Institute and UC Merced School of Engineering among others.

UCTV Director Lynn Burnstan expressed her excitement at inaugurating the new portal, “This is what UCTV is about, connecting Californians to the real-world, inestimable values that the UC provides all of California. We are very excited to be able to join these partners and give the public direct access to what they are doing for all our benefit.”

The launch features Water in the Balance, from UC Merced headquartered UCWater, a 5-minute journey from Sierra Nevada snowpack through the state’s system of dams to groundwater; Introduction to Conservation Agriculture Cropping Systems, from UC Agriculture and Natural Resources, featuring California farmers and UC scientists working together to develop sustainable farming practices and Sierra-Net, from Berkeley-headquartered CITRIS and the Banatao Institute, featuring the development of innovative cyber-infrastructure to provide real-time monitoring of the state’s water resources.

The channel’s content is appropriate for audiences of all ages and freely accessible to the public online at uctv.tv/sustainable-cal. The integrated video, article and curriculum format of the channel, in addition to its focus on biodiversity, natural resources, and low-impact living, provides users both a look at and connection to practical solutions and approaches the UC is developing, making it a valuable resource for professional practitioners, educators, and media outlets.
