Had a great time reconnecting with folks and meeting new people at #ASLOSIL26! I also had a chance to share my work and some anecdotes about Mike Pace, one of my mentors who had a session honoring him. Thanks to the organizers for an awesome conference!

GARgantuan thank you to @governorwalz.mn.gov for recognizing the value of our native fishes! FINtastic meeting him AND getting getting a photoGARph! #NativeFishDay

Scientists warn that the world’s rivers are running out of oxygen www.sciencedaily.com/releases/202... 🧪🌎

And that’s a wrap! I graduated with my PhD from UW’s Center for Limnology this weekend. I’m excited to stick around the CFL for a bit as a postdoc with Hilary Dugan working on some freshwater salinization questions. Going to celebrate finishing my degree by attending #ASLOSIL26!

If you're coming to #ASLOSIL26, check out these TWO starter packs of fellow attendees on Bluesky!

I am recruiting graduate students to start in fall 2027! Several potential projects, generally focused on analyzing and forecasting changes in aquatic carbon cycling. #ASLOSIL26 I am around all week—please reach out if you would like to find a time to chat! abbylewis.github.io/join_the_lab...

More evidence that goldfish released into lakes & ponds can transform ecosystems. besjournals.onlinelibrary.wiley.com/doi/10.1111/...

I successfully defended my PhD last week! 🎉 I enjoyed sharing all I’ve worked on over the last five years, showing that #climate alters #resilience of lake primary production to short-term perturbations by weather and nutrients. I’m excited to stick around the CFL a bit longer as a postdoc!

Great to see Madison limnology covered on NPR!

When extreme events happen together or in sequence, their impacts can be catastrophic for people and river biodiversity. Whether that’s a flood following a drought, a drought and heatwave operating in unison, or a flood falling on saturated ground, the impacts of these compound events can multiply.

It took me two years, but I’ve finally finished my latest #SciArt piece! This is a bathymetric woodcarving of Trout Lake, where I’ve spent a lot of time as a grad student. I carved it using a router and Dremel, then filled with epoxy. As I wrap up my PhD, it feels right to finish this work. #art

It's time to apply for PAID summer internships @umflbs.bsky.social ! Note that our internships are open to all and incl field & lab science as well as data science, marketing, environmental law, journalism, & education. Spread the word! attn @umontana.bsky.social flbs.umt.edu/newflbs/educ...

At #AGU2025 and interested in hyperspectral remote sensing of lake water quality and phenology? I’m excited to be presenting my research on NASA’s Hyperwall “Lite” today!

BEHOLD the GARgantuan Alligator Gar!!! This is the largest Alligator Gar I’ve encountered; at over 7 feet 10 inches (240 cm) and approximately 55 inches in girth, its weight is estimated at 300 pounds (136 kg)! A true river monster, among the largest caught, tagged and safely released! #GarWeek

Department of Biology, Lakehead University is seeking a CERC in Freshwater Sustainability and Healthy Aquatic Ecosystems.

Scientists look for cause of spike in swimmer’s itch plaguing Minnesota lakes www.mprnews.org/story/2025/0... by @kirstimarohn.bsky.social @mprnews.org

It was a bittersweet farewell to UNDERC this week as I finished the final field season of my PhD. I’m grateful for the science I got to do as part of the Cascade Project and the wonderful people I’ve gotten to work with. I’m excited to see what comes next! @ndfieldecology.bsky.social

We're hiring for a second position in my department this year! Assistant Professor in Environmental Geochemistry. aprecruit.berkeley.edu/JPF05078

"We conducted extensive monitoring prior to the removal of invasive rats and they weren't detected at all. We believe a small population held on all those years and then, without invasive predators, it finally had the opportunity to recover & grow its population." www.thecooldown.com/outdoors/lea...

Our overview of the impressive paper by Jensen et al in PNAS about under-ice oxygen levels is out. "Small lakes are suffocating as winters warm" www.pnas.org/doi/10.1073/...

I have a fully funded PhD position open for start in Jan or May 2026. Field work in peatlands of the Northwest Territories, with lab work to understand potential downstream mobilization of carbon, nutrients, mercury after thaw or wildfire. Reach out for more information, and please send on!

ID Help: This specimen was found in a stormwater management pond (SWMP) in Ontario. It was found at 1-m depth, but given the dynamic water-levels of SWMPs, it could be an emergent plant rather than a submergent (which is what we are focused on). TIA for ID help. Cc @jolatimore.bsky.social

**NEW DATABASE** - and it's a big one: BioTIME 2.0 is out! I'll guide you through why this database is a game changer for anyone interested in species on the move --> the3dlab.org/2025/05/21/b... The paper --> doi.org/10.1111/geb....

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.

The first paper from my PhD is now out in @aslo.org Limnology and Oceanography Letters! We used nine years of daily temp and chl data from Peter, Paul, and Tuesday Lakes to show that aquatic heatwaves increased surface chlorophyll concentrations during 24 out of 29 events. doi.org/10.1002/lol2...

Tonight I got to hear El Niño and La Niña! Faculty and students from @uwmad-aos.bsky.social and UW’s School of Music collaborated to turn #climate data into beautiful music. Different notes represented peaks and troughs. Musical dissonance was disagreement between climate models and observed data

You recently obtained a Ph.D. or are currently a postdoc, do not live in Canada but are looking to move to Canada? You are interested in watershed-scale carbon storage and transport? There is an oportunity to apply for a 3-year PDF fellowship in my institution (Université de Montréal), get in touch!

After 24 years of work, I’m thrilled to announce the TYMEFLIES dataset, which comprises metagenomes from Lake Mendota (Madison, WI), collected roughly every 10 days (471 samples) for 20 years! @quendi.bsky.social @robinrohwer.bsky.social rdcu.be/d5put A thread…

Got to visit the Cedar Creek LTER this week! I jumped at the chance to contribute to their chronolog of this spot by Fish Lake—you can never have too many lake photos! Now home to @ntl-lter.bsky.social

My #MacrophyteMonday plant is coontail (Ceratophyllum demersum)! This aquatic plant is a common and beneficial part of #Michigan #lake communities. It is sometimes confused with invasive Eurasian milfoil, but is easily distinguished (1/n).

Removal of ash trees due to emerald ash borer infestation did not change daytime air temps in densely-developed Madison neighborhoods (recent study by NTL scientists Elizabeth Berg and Chris Kucharik): iopscience.iop.org/article/10.1...

NTL LTER samples 11 lakes year round and the data are publicly available! Seven lakes are in northern WI and have been monitored since 1981. The other four lakes are in southern WI and have been monitored since 1995 (although some records are 100+ yrs!) lter.limnology.wisc.edu/core-study-l...

Started out my Thanksgiving morning with a visit from these otters. They were having a feast of their own!

Northwoods lake turning over brought a surprise cyanobacteria bloom today

Actually, it’s pronounced “GARter Pack” Come on, y’all should have expected this once I showed up here 😂

Cascade is hiring summer undergrads! Come work with us in the Northwoods this summer as we begin our next whole-lake experiment. More info here: limnology.wisc.edu/employment/r...

Created a Garmin watch design to include a few familiar lakes—it is currently Mendota o’clock

Frigid temps in Madison mean Lake Mendota continues to cool—just waiting to see if this means it’ll finally freeze!
