After seeing that despicable ad, I had to pitch in some more to get The Doc, @amyactonoh.bsky.social, over the finish line. Would be so proud to have her as my governor!
Today was the first time I got to do outreach, and with a middle school robotics team no less! We chatted about ecology and the challenges facing biodiversity, and got asked really insightful questions! Had so much fun 😊
New paper! Our analysis on the nutritional content of under ice phytoplankton communities is live in @ecologicalsociety.bsky.social Ecosphere! The analysis uses data from the LTER lakes to show that phytos under ice are productive & nutritious! esajournals.onlinelibrary.wiley.com/doi/10.1002/...
Nutritional content of phytoplankton communities under ice
The effects of winter environmental conditions on lake ecology can be highly variable. Ice and overlying snow isolate the water below, impeding exchange of materials among water, atmosphere, and the ...

Labor of love published! We integrated fatty acid database created by @awegalloway.bsky.social with under-ice freshwater phytoplankton data to understand how nutrition available to lake food web shifts seasonally! Under-ice plankton are nutritious! esajournals.onlinelibrary.wiley.com/doi/10.1002/...

An armed man charged at the Democratic candidate for governor in Ohio less than a week ago, and yet Republicans aren't being yelled at to turn down the temperature. The double standard is maddening.

For those keeping score at home: The Ohio GOP Senator who long refused to denounce his MAGA son-in-law who allegedly abused the senator's daughter and granddaughter is a *different Republican* from the Ohio GOP Senator who has long employed a white supremacist who likes to cosplay as Nazis.
EXCLUSIVE: A top staffer to Sen. Jon Husted (R-Ohio) appeared to wear an SS uniform while marching near Nazi flags in photos. He also created a public Spotify playlist called “Tales From Rhodesia," the White-run African colony embraced by white supremacists. Gift link: wapo.st/4xkuEa0
Couldn't agree with this more. I downloaded this document for a reason, Adobe!
As both an academic and a writer, I am repelled by the "this looks like a long document. Would you like me to summarize it for you?" that seems to appear at the top of every pdf viewer now. NO. The *entire point* of good writing (either books or journal papers) is that every sentence has a purpose.
Check out this new computer vision tool for detecting predator prey encounters in video! And see Braden’s rotifer video too
I am so excited to announce that my first first-author, peer reviewed paper was just published in @ecol-evol.bsky.social! The PrED model aims to save researchers time and resources by finding points in their videos where potential predator-prey encounters have occurred. doi.org/10.1002/ece3...

The Predator–Prey Encounter Detection (<fc>PrED</fc>) Model: Detecting Interactions Between Rotifers and Algae Using Computer Vision and Machine Learning
Using a simpler predator-prey pairing of a semi-sessile rotifer and motile algae, the Predator-Prey Encounter Detection (PrED) model aims to streamline and semi-automate video analysis of species int...

BREAKING: OMB PROPOSED RULE IS PAUSED UNTIL DEC 11th. This is a direct result of OUR ACTIVISM! It's a critical step in the right direction AND the fight continues. NOW, it's time to revoke the rule. Email here: fight2win.standupforscience.net/campaign/rev... www.theguardian.com/us-news/2026...

It's awesome to see this come out! It was a pleasure to have helped with this project.
Very excited to share that our Zooplankton International Geospatial (ZIG) data paper is out in @aslo.org LO Letters! We harmonized data across decades from 311 lakes and released it to the wild for folks to dream up their own analyses! doi.org/10.1002/lol2...
1. The new Trump / Kratsios plan for US science appears explicitly designed to destroy US universities. Diverting money to tech donors is probably just a bonus. Gift link.
Trump’s Plan for Science: More Money for A.I., Less for Universities (Gift Article)
Michael Kratsios, President Trump’s science adviser, proposed overhauling how the government funds research. Democrats said Mr. Trump’s actions had weakened science.

My zooplankton scanner is coming along nicely! I did a test run with a Daphnia individual in a drop of water on an Epson Perfection V550 photo scanner and it turned out great. The tray (Pic 2) should hold enough water to prevent that color distortion. Best part is everything came to less than $200

Here at the Reflecting Pool where a big chunk ofTrump's blue paint-apoxie has peeled off the bottom of the pool and is bobbling in the water.
As a physicist I find this hilarious. The angle of the photo is so shallow that it’s almost impossible to see the color of the water; at that angle, in that lighting, the water almost 100% just reflects the sky. So congrats to Dept of Interior for figuring out how to make the water blue, I guess?
they're baghdad bob'ing the reflecting pool btw
Of all the harm this administration has done to US science, today's proposed changes to the way federal grants are awarded and administered is the most damaging yet. The text of the federal register document is impenetrably tedious by design, so here's an excellent summary of what it says.

Recently, for *obvious reasons*, I've been thinking about what it means when anxiety and sadness are caused not by individual predispositions, but by the state of the world itself. This led me to early 19th-c. France and the notion of "mal du siècle" (sickness of the century) aeon.co/essays/young...
This means that hundreds, if not thousands of labs all over the country will close. Tens of thousands of jobs will be lost. This is in defiance of Congress's will and in defiance of good stewardship of the US economy. This is entirely because Russ Vought hates science
Less than 800 NSF grants awarded over the first half of the fiscal year for the entire country. Previous years were already over 2-3k awards by now. It is not particularly overdramatic to say we are seeing the death of federally funded science research in the United States.
