Across 36 species, population dynamics vary a lot across space. Often this is because populations span environmental gradients; losing gradients could cause large-scale population declines

Okay I know I've got a bunch of bug needs among my followers, and y'all need to see this one LOOK AT IT
This is a painted grasshopper nymph (Poekilocerus pictus). Gorgeous.
Yes, it’s real. I caught and released an adult one of these in Arondizuogu, Nigeria once. 😃 My cousin said it looked like a masquerade and I’ve thought of them like that ever since.

How bad will it be? Catastrophic.
Proposed cuts to #NSF, #NIH, and #NASA will set the US R&D landscape back 25 yrs+, cause economic and job loss now, and undermine innovations to come.
But, this is the WH's *proposed* budget.

How do ecological communities respond to pulse perturbations (e.g. storms, wildfires)? We have a solid theory for stable fixed points, but what about cycles, transients, or chaos? In this preprint, we introduce a unified framework for these nonequilibrium cases. 1/7
