Reining in large for-profit academic publishers and valuing researchers for quality over quantity must be central as we reimagine the future of scholarly publishing.

The fall of a prolific science journal exposes the billion-dollar profits of scientific publishing
One of the 15 publications that put out the most studies globally has been expelled from the indexing system for irregularities. Its publisher, Elsevier, has a 38% profit margin that reached $1.5 billion in 2024

Most ecologists know that they need to account for spatial autocorrelation in analyses. There are other forms of autocorrelation based on composition and phylogeny that similarly need to be included. The talented Toby Tsang shows how to deal with this issue. onlinelibrary.wiley....

Does good policy depend on happiness? Happier places vote for governments that prioritize evidence & science. We need to make people happier. This means investing in education, infrastructure, health care, & a high quality of life. People then feel better about society.

I went back to my hometown of Hearst, ON. While cycling gravel logging roads, after I saw 3 wolves & a bear, I realized there was no major settlement/infrastructure for 800 km ahead of me. There are so few places left on Earth where #nature is larger than humans, we need to ensure they persist.
