Resource Dynamics

Under variable resources, large sexual populations initially oscillated strongly but later stabilized toward population-resource equilibrium. Constant resources are fixed at each stage, while variable resources depend on leftovers, regeneration, increment, and population size. Resources limit population growth by increasing mortality when population size exceeds available resources. The resource model directly penalizes survival rather than reproduction when population size exceeds resources. Small variable-resource populations did not stabilize and evolved increased early mortality.
