Sleep pressure causes birds to trade asymmetric sleep for symmetric sleep Avian non-REM sleep can occur symmetrically, with both cerebral hemispheres sleeping deeply, or asymmetrically, with one sleeping lighter than the other. van Hasselt et al. find that during periods of...

Hello 👋

“86% of global deforestation occurring between 2001 and 2022 can be attributed to crop and cattle production.”

The title of the paper might lead people to think that it’s closer to 50%.

I have spent much more time putting out fires in the last 100 days than I have educating students or conducting research to address real-world problems.

Wide view of prairie with manage dropseed clumps.

Dropseed clump initiating growth that survived the March fire, but a large fraction of the clump (its meristems) were killed.

Dropseed clump completely killed by fire. No growth...living clumps show 3-6 inches of growth by now at this site.

Let's talk about the interaction of fire exclusion with the return of fire to #prairie. This bluff prairie in SW WI had not seen fire for at least many decades and was being encroached on by woody vegetation. Low herbaceous plants had been excluded from large portions by excessive thatch. 1/

#WorldWildlifeDay 2025 is here!

To celebrate, we’re highlighting recent #DNABarcoding research that enhances our understanding of wild animals and plants

Today, we’re focusing on 🧬🔬 methods to ID species, with a comparative study on butterflies, bumblebees, and parasitic wasps 🦋🐝.

Look at this Huernia zebrina flower! So amazing and unreal looking, as if made of rubber and belong to an alien world. #iamabotanist #plantjoy 🧪🌱🌸

Flowers that cool themselves: thermal ecology of summer-blooming thistles in hot Mediterranean environments Flower exposure to high temperature reduces the production, viability and performance of pollen, ovules and seeds, which in turn reduces individual fecundity and risks the survival of populations. Aut...

I spent the last five summers sharing the infamous mediterranean heat with 15 species of thistles that flower at that somewhat absurd time of year, seeking to understand (something about) their thermal ecology.

Here are the results. I think all my sweat was worth it.

We are removing the largest and longest-lived animals, which can be detrimental to those species dependent on migration, sociality, and cultural transmission to survive. Paper in Science by @kellerfish.bsky.social et al.: www.science.org/doi/10.1126/...
