- Interesting summary to reflect on “what’s the point” of science, and how the publication system will interfere on the science we need.
- I enjoyed Carl Bergstrom's @carlbergstrom.com talk today @unswbabs.bsky.social on the current 'Peer review meltdown' phenomenon. Misery loves company, so I was glad to find out I'm not the only editor struggling to find reviewers. Carl et al. have narrow it down to a few factors including ->
- Reposted by Helena VallicrosaWhat if plant N & P cycles aren’t as linked as we thought?🤔Our new @journalofecology.bsky.social paper shows that global change decouples them, challenging existing asumptions & showing the need 2 incoporate this decoupling into models to predict global change responses doi.org/10.1111/1365...

- Reposted by Helena VallicrosaDo you define trees as either needle- or broad-leaved? Are you doing this correctly?
