As the Moon eclipsed the Sun on 8 April 2024, birds took note.

Leveraging nature’s own experiment, scientists and the public joined forces to show how different species responded to sudden midafternoon darkness followed by a new “dawn.” Learn more this week in Science: https://scim.ag/48WbhLL

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

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....

An almost full disk is next to a dot, the star Antares. On the next evening, a disk, representing the full moon, is to the lower left of the dot.
