Has aquatic science shifted away from population ecology toward other scales? A bibliometric analysis suggests population-focused language peaked around the 2010s and has since declined, while community-focused language has continued to rise. What do others think? rpubs.com/bkraemer/AquaPopCom_v1
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). 🌎🌍🌏
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.
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...
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...

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 esajournals.onlinelibrary.wiley.com/doi/10.1002/...
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....

"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.🚣♀️⛰️🌊
