Non-neutral community dynamics: empirical predictions for ecosystem function and diversity from linearized consumer–resource interactions

Summary, in English

A general model of linearized species interactions, essentially Lotka–Volterra theory, applied to questions of biodiversity has previously been shown to be a powerful tool for understanding local species–abundance patterns and community responses to environmental change for a single trophic level. Here this approach is extended to predict community composition and responses to environmental changes in trophically structured systems. We show how resource and consumer species richness and their relative abundances vary with the means and variances in enrichment level and strengths of intra- and interspecific interactions. Also demonstrated are the responses of local resource and consumer species richness to the global species pools at both trophic levels, as well as the covariation with net resource productivity. These predictions for resource and consumer specific responses to changes in environmental enrichment and global biodiversity are directly testable
