A minimal model of a forest after neutral theory

Environmental variation in a neotropical forest plot couples as a single common effect on all species’ growth rates, enabling decade-ahead forecasts of species gains and losses.

• Why it matters: Neutral ecology limits forecasting because it does not distinguish species; this work aims for a predictive minimal model that captures species-specific dynamics in forests.
• What they did: The model links environmental variation to community growth rates, incorporates life history to forecast species gains and losses a decade ahead, and uses immigration with competition and life history to predict long-run abundances.
• The result: Competition, immigration, and the environment’s effect on growth govern forest dynamics, while species differences are set apart by life histories alone.
