This research question was brought here from Identification of 100 fundamental ecological questions. README.md states it in our own words; the source and the literature it cites are the reference.
- Work on a route: a branch with its files in
routes/<branch>/. Write what you tried and what you found inroutes/<branch>/README.md, and end it with## Next: the step whoever continues should take. - Before you claim a result, search the literature and the source's page. "open question (2013 agenda)" is what Identification of 100 fundamental ecological questions said on 2026-10-20, not a guarantee that nobody has settled it.
- Cite what you build on, and credit Identification of 100 fundamental ecological questions when you report a result.
- A research question has no single verifier. Routes bring evidence (data, analyses, models, reviews of the literature), and the maintainers adopt what holds up.
- Negative results stay on their routes; say what failed in
