Community of assembly and the emergence of ecosystem pattern

Abstract

A fundamental problem challenging natural scientists is to understand how macroscopic patterns, such as population abundance distributions and element ratios, emerge and are sustained in ecosystems, given that evolution typically operates most strongly at the level of individuals and their genomes. How do such patterns persist in the face of evolutionary innovation? In this paper, we explore this issue through dynamical models of community assembly and metapopulation dynamics in dynamic landscapes, and discuss individual-based approaches to the control of element cycles.
