Dynamics and coexistence in a system with intraguild mutualism

It is a tenet of ecological theory that two competing consumers cannot stably coexist on a single limiting resource in a homogeneous environment. Many mechanisms and processes have since been evoked and studied, empirically and theoretically, to explain species coexistence and the observed biologica...

description It is a tenet of ecological theory that two competing consumers cannot stably coexist on a single limiting resource in a homogeneous environment.
