A paper 5y in the making: Climate change could amplify weak synchrony in large marine ecosystems
t.ly/AkuS0

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

A 23% reduction in staff at the EPA and closure of their research program will make it much easier for companies to pollute land, water, and air without being held accountable. This will hurt all of our children and grandchildren. This is very sad to watch. 🧪

a new study found that experienced open source programmers became 19% less efficient when they used AI tools, because they spent more time prompting and reviewing AI generation output than they saved on coding.

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.

Speak up now before it is too late.

Soybeans and sirloin are not incompatible with science.

But a country that only produces soybeans and sirloin is going to run into some recurring, structural problems.

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

📣 Comments can be short. Courts consider them—and scientists with NSF/NIH experience are especially impactful

ELECTION RESULT: A team of city council members in Rolla, Missouri, have been pushing anti-LGTB policies, including a ban on drag shows and book censorship.

Voters just ousted all three of these city councilors who were running for reelection, backing candidates backed by a local LGBT group.

Made a pop dyn lecture for my bio freshmen, and I effectively called discrete-time models "seasonal models".

Because discrete vs continuous time dynamics really differ with nonoverlapping generations. And most of the time generations don't overlap because of seasonality.
