"Is plastic pollution getting worse?" It's the question we get asked more than any other. After 15 years of data from Lord Howe Island, we finally have a straight answer. 🧵 🔗 agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Meta-analysts ask researchers to share reusable data, but are we leading by example? Great work by @shreyadimri.bsky.social, @asanchez-tojar.bsky.social & more. Of 81 meta-analyses, 68% shared data, only 15% shared code, and none reported a risk-of-bias assessment. ecoevorxiv.org/repository/v...

Flikk admiring the work of the Swedish army (in 1567) at Domkirkeodden in Hamar. After burning the building and bishops palace the ruins were «recycled» by locals. In 1998 a huge glass dome (the biggest in Europe) was placed over the remains to protect it from the weather (& presumably those locals)

Why do so many ecological systematic reviews cite PRISMA but not the CEE Guidelines? Are we teaching reporting standards but not conduct standards? Curious to hear from editors, reviewers and those teaching synthesis in ecology. #EvidenceSynthesis

I can't stress enough how disrespectful it is when colleagues in the Global North publish papers about our realities without a single author from the region. It's not "just data." Context matters. Interpreting our realities through your own framework isn't just exclusionary, it's weaker science.

This looks useful. A typical meta-analysis in ecology mixes experiments with observational studies, mixes coefficients with different controls and therefore different causal meanings. I would not normally say "hey the folks in medicine are doing it right, imitate them" but in this case maybe
