Titre | Random interactions and high-dimensionality in ecology |
Résumé | Natural ecosystems exhibit astounding richness. This suggests that we treat them as many-variable interacting systems, but is there any evidence to support this perspective? I will discuss possible footprints of high-dimensionality, including phase-transitions, and thermodynamic variables which determine the systems large-scale behavior. The latter are found in a wide range of accepted models in the field. Then, Ill present a theory for how interactions organize to allow many species to coexist. Data from plant-competition experiments confirms the theoretical predictions, providing evidence for high-dimensionality in that ecosystem. |
