• The lab is full steam ahead this Fall 2019! We started scouting sites for our CADFW Delta restoring wetlands project, we are building traps for the field experiment at Pinnacles, and we are making progress in our data-driven projects (river-reservoir dynamics, CA drought, created wetlands, metacommunity stability).
• Guillermo and Kyle presented at the California chapter of the Society for Freshwater Science (CalSFS) – California Bioassessment Workgroup (CABW) meeting at UC Davis.
• Albert coauthored a review in Science, with SESYNC director Margaret Palmer, on the importance of flow regime for river ecosystem restoration. Check it out here! [see associated interview].
• The lab hosted Sebastien Rauch and Ekaterina Sokolova, who visited us from Chalmers University of Technology, Sweden.
• The lab also hosted John Sabo, director of Future H2O (Arizona State University), with whom we continue to collaborate on spectral methods and hydrologic regime shifts.
• Albert joined the editorial board of Conservation Letters, a leading journal on interdisciplinary conservation science.

More soon! 🙂

Jessie Moravek, Ph.D. student in the lab, gave a TEDx talk at the TEDxFulbrightGlasgow event last June, on hydropower development and its impacts on ecosystems and people. The talk is online now. Check it out here!

Interview with the PPIC Water Policy Center.

• We welcome Jessie Moravek and Megan Pagliaro to the Ruhi Lab! Jessie is interested in studying the impacts of hydropower dams, and potential for mitigating them via reoperation and removal; and will be co-advised by Justin Brashares. Megan has been putting together an exciting research project on wetland restoration trajectories in the San Francisco Bay. Read more about them and their inspiring interests!
• We also look forward to hosting Tadeu Siqueira, Brazilian sabbatical visitor who received a FAPESP grant to research metacommunity dynamics under environmental fluctuations; as well as Ph.D. student Zhenhua Sun, who is visiting this Fall from Sweden to study biodiversity benefits of stormwater ponds. Welcome all!

The Ruhi Lab will receive funding from the California Department of Fish and Wildlife, for the project ‘Reconnecting Delta food webs: evaluating the influence of tidal marsh restoration on energy flow and prey availability for native fishes’. This Fall we will start a 3-year project combining analyses of community composition, stable isotopes, and sensor time-series data, in collaboration with USGS and ICF, via State Water Contractors. More soon!

I am Tongbi Tu, a new postdoc in the lab.  I am working on a SESYNC Pursuit to study causal pathways and feedbacks within complex water management systems. This project integrates ecology, hydrology, and water law. The interdisciplinary team is composed of Sankar Arumugam (NCSU), Xiaoli Dong (UC Davis), Caitlin Dyckman (Clemson Univ.), Ted Grantham (UC Berkeley), Lars Olson (Univ. of Maryland), Benjamin Ruddell (Northern Arizona Univ.), Nicola Ulibarri (UC Irvine), and Albert Ruhi (UC Berkeley).

In this working group we will apply physically-based and time-series models to investigate how reservoirs can help provide engineered resilience to socio-environmental systems–especially during periods of drought. We will use a variety of approaches to detect direct and indirect causal pathways and feedbacks between hydrologic conditions, human uses, and downstream ecological outcomes in the Lower Colorado River basin. A better understanding of the complex dynamics of water systems can help advance sustainable freshwater management–a critical need in the face of increasing competition for scarce freshwater resources.
