Registration is open for the 2026 Global Lake Ecological Observatory Network (GLEON) All-Hands’ Meeting taking place at Lake Banyoles, Spain from August 30 - September 4, 2026! Participation support for students/ECRs is available through the Freshwater Futures Fellowship (deadline April 24). 🌎🌍🌏

Just in case you had any doubts that ChatGPT is still hallucinating.

😂😂😂😂😂😂😂😂😂😂

Quick experiment: Please take a moment and ask ChatGPT in conversation mode (use voice) how many "R's" there are in the word "strawberry." Comment here what answer it gives.

After two years of focusing my aquatic ecology class almost entirely on lakes, I’m excited to expand into stream ecology this year. We will compare and contrast depth gradients in lakes with elevation gradients in a nearby stream which climbs from 312 m to 659 m, all within just 3 km of campus.

Seasons and seasonality in lakes: A synthesis amid global change Seasonality in environmental conditions plays a fundamental role in shaping lake ecosystems. However, patterns of seasonality vary worldwide, and these patterns are shifting over time amid global cha...

In aquatic ecology, what is “spring”? A calendar date, a daylength threshold, or the moment lake ice melts? Led by @aslewis.bsky.social , we show how seasonal definitions fundamentally shape our understanding of climate change impacts on waterbodies. dx.doi.org/10.1002/lol2...

Fundamentals of Data Visualization A guide to making visualizations that accurately reflect the data, tell a story, and look professional.

@kjhealy.co makes some of the best open free online guides to data visualization #datavis. I’ve always loved and used clauswilke.com/dataviz/ in my teaching and research, but this one looks even simpler and more user-friendly. Definitely worth checking out.

Data Visualization A Practical Introduction

A black-and-white xkcd-style comic. Two stick figures stand talking. One says, “Lake classification is second nature to us limnologists, so it’s easy to forget that the average person probably only knows one or two trophic states.” The other replies, “And mixing regimes, of course.” A caption below reads: “Even when they’re trying to compensate for it, experts in anything wildly overestimate the average person’s familiarity with their field.

This @gleonetwork.bsky.social workshop series is aimed at limnologists but it's open to all. We are targetting PhD students and postdocs across the environmental sciences.

Poster for 90 minute workshop on HOW TO DESIGN BETTER EXPERIMENTS, by Mridul Thomas & Ravi Ranjan. Details: September 23rd 16:00 CEST ; 14:00 UTC Description: Experimental designs can make or break an experiment. A good experiment has a clear goal and efficiently uses experimental resources to achieve that goal. In this workshop, we will review what experiments are for, basic and advanced principles of designing experiments, and how to use simulations to evaluate designs before actually doing the experiment. We’ll do a moderate amount of coding in R and so experience with this would be helpful but is not required. We intend to have small-group discussions to help participants develop their own experiments, and encourage participants to think of a specific question they would like to answer with an experiment.

@raviranjan.bsky.social & I are teaching a free online workshop with on experimental design for environmental scientists on the 23rd.

We'll focus on using simulations to evaluate how well different experimental designs help achieve your goals.

Clarifying the trophic state concept to advance macroscale freshwater science and management For over a century, ecologists have used the concept of trophic state (TS) to characterize an aquatic ecosystem's biological productivity. However, multiple TS classification schemes, each relying on....

It takes patience to have a conversation about definitions as a collaboration begins... but it is important!
"Trophic state" in lakes is one of those concepts! It really makes a difference which definition we use... @mishafredmeyer.bsky.social

Analog US spy satellite images from the 1960s are revealing unexpected surprises—this time, it's penguin poop! So, what does the poop tell us in our latest preprint? Work lead by Martynas Bielinis, @drmichellelarue.bsky.social, myself, and Catalina Munteanu

Back in my happy place: sending more fully equipped students out to explore lakes in the Black Forest—waters which, to my knowledge, have never been touched by aquatic ecologists. Let the discoveries begin. 🛶🧪🌲

"Absolute teaching bliss" ☺️ is sending two bachelors students in a kayak to collect the first ecological data in over 70 years from a lake so protected, swimming and boating are off-limits. With special permission granted, they’re experiencing something virtually no living human has experienced.🚣‍♀️⛰️🌊

Replies to criticisms of my posts on ChatGPT & the environment Why I used 3 Wh, and why I don't say "Every Watt-hour matters"

Here is the response to reviewers: andymasley.substack.com/p/replies-to...

"If you're already trying to live low-impact—recycling, avoiding plastic, limiting flights—here’s a chance to make a meaningful tech choice that aligns with those values. LLMs aren't evil by default, but they’re energy-intensive, and we need to ask whether the benefits we get justify their costs."
