I'm very excited to announce that I’ll be joining the University of North Florida as an Assistant Professor! I’m so grateful for the support and collaborations that made this possible.

So excited to share our new paper out today in Ecological Applications @esajournals.bsky.social! We used time-series modeling explore ecological risk for fishes and their prey in the San Francisco Estuary during key phenological windows that shape food web dynamics. dx.doi.org/10.1002/eap....

Billions of gallons of water flow daily through California’s water projects. In this National Academies Report we examined key actions to protect endangered fish & Bay-Delta ecosystems while considering human water needs nap.nationalacademies.org/catalog/2913... #WaterResources #CentralValleyProject

At my first Western Society of Naturalists meeting presenting some of our work looking at sea otter restoration! Looking forward to introducing myself to a new scientific society and engaging with a new audience. Please reach out if you want to connect! #WSN2025

How vulnerable are riparian trees to drought? Using groundwater and satellite data from a California waterhsed, our new paper found that trees by drying rivers lost up to 5 weeks of growing season, suggesting they’re nearing critical groundwater limits. onlinelibrary.wiley.com/doi/10.1111/...

Does tidal marsh #restoration "work", if the goal is bringing back key species AND the trophic interactions that support them? A thousand stable isotope samples later, we have answers! 💯 work by PhD student Megan Pagliaro: esajournals.onlinelibrary.wiley.com/doi/10.1002/... #SanFrancisco #BayDelta

Looking for a postdoc, and interested in river-coastal linkages, #remote sensing, and time series analysis? Come work with us @natureatcal.bsky.social on an exciting project led by @rachelspatial.bsky.social! CC @sfs-src.bsky.social @aslo.org @cerfscience.bsky.social ‪‪@caseagrant.bsky.social‬

So great to see our work on blue dasher dragonflies highlighted in the New York Times. Excellent piece by @cjgiaimo.bsky.social! www.nytimes.com/2025/08/16/s...

Anyone at #esa2025 this year? Get in touch!

UC-Berkeley has an open-rank faculty position in our incredible Climate Equity and Environmental Justice (CEEJ) research cluster. It is an extraordinary interdisciplinary group working across multiple colleges and departments at the university! More information here: aprecruit.berkeley.edu/JPF04842

👥 10 students. 🌎 1 mission: a healthier planet. Meet the 2025 Benioff Scholars—driving real-world solutions to some of the planet’s most pressing environmental challenges.

An international, interdisciplinary group focused on advancing seaweed research, cultivation, and application gathered at UC Berkeley in early May for the inaugural workshop of the International Bioeconomy and Macroalgae Center.

This threat represents an immeasurable loss to community-driven research and to the training pipeline for the next generation of collaborative conservation leaders

New collaborative paper out in Ecology - subsidy timing matters in producing intraspecific life-history diversity; Led by Rui Ueda at Kyoto University esajournals.onlinelibrary.wiley.com/doi/10.1002/...

Professors at USGS coop units were absolutely critical parts of my education at 3 different universities. They're probably affiliated with more useful conservation research than any other agency on earth. Join the rally to defend science next week! 🌎🐟🦉🐍🦊🌿🧪 #hydrology #Invert mobilize.us/s/JyAqUI

Racist and sexist roots in the cancellation of NSF grants under Trump: Grants with female PIs canceled 2x more than men Grants with Black PIs canceled 4x over White PIs Grants with Hispanic PIs canceled 2x over White PIs Grants with PIs with disabilities canceled 2x more than without

The result of nearly two decades of work, my coauthors and I have just described two new crayfish species from western North America: introducing the Misfortunate Crayfish and Okanagan Crayfish (doi.org/10.11646/zoo...). More to follow soon, but it should be open access - message if you need a PDF.

A colleague at Stanford’s business school used The Stanford Daily to argue—poorly—against DEI. The piece was riddled with historical errors and left one searching for fact, so I broke my public writing hiatus to respond. I hope you’ll read and share the piece. stanforddaily.com/2025/04/22/w...

Happy about this one, skillfully led by Adrianne Smits & w/ many great coauthors!-> "Despite substantial increases in the volume of #freshwater data collected worldwide, many regions and ecosystems still lack sufficient data collection and access." esajournals.onlinelibrary.wiley.com/doi/full/10....

📢 GLOSSAQUA is out in Ecology @esajournals.bsky.social. Big collaboration w/40+ coauthors led by myself, @chaevangelista.bsky.social & @ignasiarranz.bsky.social. It compiles global size spectra parameters from aquatic ecosystems globally👉: doi.org/10.1002/ecy.... #datapaper #aquaticecology 🌍🧪🧵(1/4)

Looking for a quantitative ecology #postdoc? Check out this opening on time-series modeling of estuarine food webs - based in my group @natureatcal.bsky.social, in collaboration w/ State agency scientists. Apply ASAP - review of applications starts Apr 4. More info: aprecruit.berkeley.edu/JPF04818

University of California announced a systemwide hiring freeze. This affects not 1 but 10 campuses (including UCLA, UC Berkeley, UC San Francisco, UC San Diego among others) plus 3 national labs with impact on medical and scientific research and local economies. www.reuters.com/world/us/uni...

As a USGS Coop Alum (PhD at the Arkansas Unit) this is incredibly alarming. These units are key engines of applied research and training of the next generation of scientists, biologists and land managers. My peers are now leaders across state and federal agencies, non profits and universities.

Delighted to share our new paper in Ecology Letters: Variation in Salmon Migration Phenology Bolsters Population Dynamics but is Threatened by Drought. With @fishteph.bsky.social, Ted Grantham, and Mariska Obedzinski. #rivers #fishes #salmon 🧪🐟 🧵(1/8) doi.org/10.1111/ele....

A 12-year-long study led by @ucberkeleyofficial.bsky.social and @caseagrant.bsky.social researchers finds that the alternative life histories of coho salmon have made their populations more stable.

Check out my favorite dissertation chapter 👇🏻 made possible by @adamsiepielski.bsky.social, & former lab mates Tara Lanzer and Taylor Ping, who helped me assay hundreds of bugs when covid restrictions were in place.

If you're interested in river drying and cross-ecosystem linkages, check out our new Ecology paper led by undergraduate extraordinaire Amin al-Jamal! -> Aquatic top predator prefers terrestrial prey in an intermittent stream esajournals.onlinelibrary.wiley.com/doi/10.1002/...

A really cool paper from our incredibly talented former undergraduate, Amin al-Jamal (so far bluesky-less) is out in Ecology! It’s also my first senior author paper! We looked at the feeding habits of everyone’s “favorite” predatory stream insect—the giant water bug. doi.org/10.1002/ecy....

Which exploitation strategy should be adopted for salmonid metapopulations? 🎣 Could knowledge of source-sink dynamics improve their management? Our latest paper is just out! onlinelibrary.wiley.com/doi/10.1111/... Simulations results 📈 suggest being not selective as the best strategy 💡

What a good way to ring in the new year! Our new paper is (finally) out in Ecology Letters! doi.org/10.1111/ele.... We looked at climate driven phenological patterns across food webs in the San Francisco, Chesapeake, and Massachusetts Bay estuaries.

Grateful to be in a lab that loves watching fish as much as I do. @fishteph.bsky.social @roygbivv.bsky.social @robfour.bsky.social And the rest of the Berkeley freshwater labs crew

Really happy to see this one out, superbly led by Tadeu Siqueira & with the participation of a great team! On how the mechanisms conferring community stability vary across trophic levels in freshwater ecosystems: esajournals.onlinelibrary.wiley.com/doi/epdf/10....
