Joint effects of resource supply and resource types on properties of population dynamic models

We explored how the resource supply ratio affected the critical parameters including species’ intrinsic growth rate and interaction strength in phenomenological models, and consequently the population dynamics.We fitted the Lokta-Volterra model and the Reciprocal model to simulated population dynamics generated by mechanistic consumer-resource models with known underlying ecological processes.We investigated how the predictive abilities of phenomenological models change with the speed of resource dynamics relative to consumer dynamics in one consumer-one resource system via simulation experiments.
