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. On the shores of Lake Superior, Experimental Lakes Area and Large Lakes Observatory both just down the road... Deadline Dec 1. DM for questions! www.lakeheadu.ca/faculty-and-...

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/...

Interested in managing graduate ecology programs and supporting excellent students? Come join us in the Dept. of Integrative Biology at @uwmadscience.bsky.social Apply by August 10. jobs.wisc.edu/jobs/graduat...

JOIN US!!! @garlab.bsky.social is looking for a PhD and MS student to join our team studying ecology & conservation of gars, bowfin, and other non-game native fishes beginning Spring 2026! Posting & more info coming soon. Please DM or email [email protected] with CV if interested!

Come join the MU Limnology Lab as the new field manager! To apply for this position, please visit the MU web site at hrs.missouri.edu/find-a-job/s... and look for job opening ID 56749.

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

I'm very excited to share that Hacking Limno + DSOS are coming back for the FIFTH time 21-25 July! If you're interested in #machinelearning #remotesensing #modeling #limnology #oceanography, this is for YOU! Registration is FREE + open to ALL! #DSOS25 aquaticdatasciopensci.github.io/registration/

**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!

Are you excited as I am? BECAUSE IT’S PHOSPHORUS WEEK ! Official declarations from governors of N Carolina (below), Wisconsin, and Illinois ! governor.nc.gov/governor-pro...

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!

I am looking for a PhD student to start in fall of 2025 at MSU. Potential topics include trait-based approaches to plankton community resilience, temperature effects on communities, harmful algal blooms and many others. Please get in touch if interested. More info: www.kl-lab.group.

Lots of exciting papers in the current issue of ECOSYSTEMS--check out the TOC. Excellent submissions in ecosystem ecology (terrestrial, aquatic, marine) are always welcome, so keep us in mind. link.springer.com/journal/1002...

Here's a Limnology starter pack! I am sure I left great people out so tag me so I can add them. go.bsky.app/Qv3DLZ6

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!
