Oxygen supply through the tracheolar–muscle system does not constrain insect gigantism - Nature New evidence suggests that diffusive oxygen transport through the tracheolar–muscle system is not the limiting factor on insect body size.

Seems like a pretty important result; title says it all.

Braided rivers look chaotic, but their food webs tell a different story.
Using stable isotopes, we found that fish, birds, and spiders connect resources across huge spatial scales — revealing hidden structures that help stabilise these dynamic ecosystems.

I've finally got around to curating a selection of films about the #climate crisis 🎥

There's lot of mediocre climate films out there, but for me these stand out head & shoulders above the rest 🎞️

They make excellent resources for classrooms, lecture halls, or community cinema's 🎬
