So excited that this work is finally out in the world! An example of working with practitioners to develop a mathematical model that can provide insight into the usefulness of management methods for coral reef health in the region.

How do you know whether or not your conservation monitoring program is helping you to deliver outcomes? We have made a checklist of 15 distinct reasons - some more directly connected to outcomes than others.

A study I'm proud to have contributed to, led by @katehelmstedt.bsky.social @matthholden.bsky.social @hugepossum.bsky.social! The study pushes for people to explicitly consider for what purpose they are pursuing environmental monitoring, and gives 15 example reasons.

I gave a keynote talk to the Pennsylvania Academy of Science on Friday. Over 100 STEM undergrads from small colleges and universities from across the state, gathered in the Capital.
I talked about the economic, aesthetic, and humanitarian impact of science. And I showed this slide.

Reality check: coral restoration won’t save the world’s reefs
~ Without coral reefs, the world would be a much poorer place. So when corals die or become damaged, many people try to restore them. But the enormity of the task is growing as the climate keeps warming.

Reality check: coral restoration won’t save the world’s reefs
New research examined coral restoration projects worldwide to calculate what it would actually cost to bring back what’s already been lost.

🚨BREAKING. From a program officer at the National Science Foundation, a list of keywords that can cause a grant to be pulled. I will be sharing screenshots of these keywords along with a decision tree. Please share widely. This is a crisis for academic freedom & science.

The logical conclusion is - we need to reduce “human pressure levels” to save the world’s coral reefs.

New preprint out w @colebrookson.bsky.social where we use a model to explore when coral restoration is a practical method of coral reef mgmt! Spoiler alert - paying attention to human pressure levels is 🔑, if they're too high, restoration attempts are unlikely to promote long-lasting healthy reefs!
