Super happy to have @ulaskimarta.bsky.social joining us at @uwsafs.bsky.social! Looking forward to working together!

Mismatches between invasive species policy, which relies on administrative borders, and scientific research conducted at ecological units complicate regulation, risk assessment, and biosecurity. Here we explore some solutions. www.nature.com/articles/s44...

Welcome the editors for FieldNotes 2026! pt. 1 We're so excited to introduce the editors of our editorial team! Stay tuned for the remaining editors and other updates!

‪Another wonderful CESAB FOOD-WEBS working group meeting in Montpellier! Super productive and creative time together. Funding: @frbiodiv.bsky.social

River need greater protection, but to date our methods for tracking protection status have been limited. In this post I describe a new method from @oldenfish.bsky.social @americanrivers.bsky.social and Conservation Science Partners - the Protected River Index www.forbes.com/sites/jeffop...

🗣️ MAJOR ANNOUNCEMENT: Over 80% of our nation’s 4.4M miles of rivers aren’t adequately protected! Our brand new peer-reviewed research with Conservation Science Partners published in Nature Sustainability shows just how vulnerable our rivers are. ➡️ Learn more: www.americanrivers.org/npra-explore...

Late night, but there is no better feeling that having stable isotope samples all prepped! ⚛️🎉

Finally found some time to reconnect with my caps. Red swamp crayfish in all its glory. Adding it to my office wall! @newbelgium.bsky.social @pikebrewing.bsky.social

Sunrise from UW SAFS @uwsafs.bsky.social. Not a bad way to start the day! ☀️

Is Facebook fueling the online trade in aquatic invasive species? Survey of hobbyists indicates that over half engage in peer-to-peer organism exchange, transport across state lines & release them into the wild. AI Podcast: open.substack.com/pub/oldenfis.... Paper: www.reabic.net/journals/mbi...

The current website of the US Department of Agriculture. What a nightmare.

I've been proud to serve as the faculty leader for this effort. It has been a pleasure to interact with passionate students and emerging science communicators for many years now! We publish annually. I encourage you to check out past issues and follow! @uwsafs.bsky.social @trevorabranch.bsky.social

Fish ecologists routinely posit that functional trait analyses, founded either solely or in part on morphological traits, provide opportunities to guide global biodiversity conservation. Our paper just published in GEB sought to explore this claim. doi.org/10.1111/geb.... Read thread below.

It was a real pleasure to participate in the Mazama Newt Workshop at Crater Lake hosted by the @oregonzoo.bsky.social and the National Park Service. Discussions focused on a recovery plan for the Mazama newt in light of an exploding invasive signal crayfish. Great to see @ericrlarson.bsky.social!

Just out: Few-shot transfer learning enables robust acoustic monitoring of wildlife communities at the landscape scale. Super great work by Gio Jacuzzi. doi.org/10.1016/j.ec.... Github release: zenodo.org/records/1569...

Wonderful to be able to spend some time at @iea-udg.bsky.social at @univgirona.bsky.social with my host and friend @garciaberthou.bsky.social. Looking forward to my seminar in a few hours!

A huge congrats to Dr. Diallo @jessdiallo.bsky.social! Many more great things lay ahead!

Another wonderful CESAB FOOD-WEBS working group meeting!. Such a wonderful and productive time (managed to submit 2 papers during the meeting) Special thanks to @profchrisharrod.bsky.social for hosting us at @sceneuog.bsky.social in Scotland! Funding: @frbiodiv.bsky.social

The impact of invasive fishes lasts a lifetime - we found lifetime trophic shifts in native species using fish eye lens stable isotope analysis coupled with otolith growth measurements 🐟 👁️ 📈 Check out the new pub with @oldenfish.bsky.social esajournals.onlinelibrary.wiley.com/doi/10.1002/...

Management struggles to keep pace with invaders. With @jessdiallo.bsky.social and others we demonstrate the utility of removal models to help improve invasive removal programs & robustly evaluate the success of population suppression & eradication. esajournals.onlinelibrary.wiley.com/doi/10.1002/...

I miss this article last week in all the chaos - but it's well worth the read. Thanks @jjopperman.bsky.social for all you do!

🔊 America’s Most Endangered Rivers® of 2025 report! From Alaska to New Jersey, whether threatened by drought, mining, or flooding, these 10 rivers all have one thing in common: they are all at a tipping point, facing an urgent decision in the coming months. Take action: mostendangeredrivers.org

Dear friends and colleagues! I'm looking for a riparian zone (area) spatial layer for 🇨🇦 Canada 🇨🇦 (or ind. provinces/territories). Something simple that has been delineated using a DEM and estimated flood height, for example. Image below is purely eye candy. Many thanks ... from a Canadian 🇨🇦

Just returning from the Texas A&M Ecological Integration Symposium (eeb.tamu.edu/eis/). Thanks to the student organizing committee and all the other invited speakers! I presented on the current protection status of American's rivers and threats to protections in the future. @tamu.bsky.social

Really looking forward to reading this paper by Christina McCabe @jdtonkin.bsky.social and others! www.nature.com/articles/s44...

We can protect our nation’s freshwater species by: ✅ Removing Dams ✅ Restoring Damaged Rivers ✅ Protecting Healthy River Habitat Take the pledge to stand up for all wildlife that depends on rivers #WorldWildlifeDay act.americanrivers.org/page/80077/p...

A wonderful collaboration with friend Andre Padial and other Brazilian colleagues. We explored changes in biogeographic patterns in global fish diversity caused by the spread of non-native species, teasing apart the geographic and taxonomic drivers of change. neobiota.pensoft.net/article/1266...

Identifying and Approaching Barriers to Environmental Flow Implementation Using Social–Ecological Systems doi.org/10.1002/wat2... A wonderful collaboration with Maddy Grupper, Avril Horne and Angus Webb at University of Melbourne. @nature.org @wwf-water.bsky.social

Human barriers are replete across the world! This paper just out in Nature Water aims to advance a more comprehensive river barrier mapping solution to support environmental management www.nature.com/articles/s44... @jjopperman.bsky.social @americanrivers.bsky.social @wwf-water.bsky.social

Invasion ecology is replete with a body of well-supported yet contradictory evidence for numerous invasion hypotheses, likely as a result of context dependency. Just published in DDI we explore the indirect effects & context dependencies in fish invasions. onlinelibrary.wiley.com/doi/10.1111/...

We often think of rivers as linear features, but lateral dynamics are just as important and often overlooked! In our paper we present a framework for the study and management of rivers which emphasises lateral connectivity. #floodplainconnectivity #riverrestoration Link to paper shorturl.at/ri3lA

A wonderful holiday card from @clairevaage.bsky.social. It’s impossible not to get holiday cheer from an eastern mudminnow! With the added bonus of Olden Lab stickers!

New paper in @freshwaterscience.bsky.social reporting on the efficiency and effectiveness of an innovative new methodology called autonomous suction harvesting that controls aquatic invasive plant using a ROV instead of a diver . Paper <- dx.doi.org/10.1086/733211 or find at RG @uwsafs.bsky.social

People often ask me "what do you work on?". At the end of an exhausting day, I wish I could make stickers of this word cloud and just slap it on their shoulders! ;)

Our new study reports that over 13,000 human barriers fragment close to THREE-QUARTERS of all rivers in the Mekong River Basin. Paper is free to access here: doi.org/10.1016/j.rs....

Hydropower impacts on riverine biodiversity. A paper recently out in Nature Reviews - Earth and Environment with @fengzhihe.bsky.social @scjaehnig.bsky.social jcsvenning.bsky.social and others! A good one-stop shop for understanding the impacts of hydropower dams. www.nature.com/articles/s43...
