Evolution of resource cycling in ecosystems and individuals.

Given a fixed amount of resources, this leads to resource cycles. We find that the shortest cycle dominates the ecological dynamics, and over evolutionary time ...

Evolution as an ecosystem process: insights from genomics

Evolution both generates and maintains the biodiversity of global ecosystems, and as such is a fundamental ecosystem process (Holt 1995; Matthews et al. 2011; ...
