Contribution of microcosm experiments to conservation science
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract Microcosms, or miniature experimental systems, have been used to develop models and theories in ecology. However, their contribution to conservation science is unclear. We explored the application, design, and impact of microcosms in conservation science from 469 systematically identified articles published from 1986 to 2023.
