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

Proceedings of the National Academy of Sciences (PNAS), a peer reviewed journal of the National Academy of Sciences (NAS) - an authoritative source of high-impact, original research that broadly spans...

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. 🧪

EPA eliminates research and development office as it begins thousands of layoffs

The Environmental Protection Agency said Friday it is eliminating its research and development arm and reducing agency staff by thousands of employees.

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.

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.

(inflation adjusted $-s below)

NSF, NASA and NIH budgets per year, inflation adjusted from 2000-2025 along with the proposed cuts. NSF includes research component only. Massive cuts across all sectors, well below support spanning 25 years.

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

🚨 A new rule would let career scientists like NSF/NIH program officers be replaced by political appointees

Already 14,000+ public comments, deadline is Friday

📣 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.
