报告摘要: A PDE-ODE coupled dynamic model is proposed to describe the asymmetric competition for light and nutrients between producers in a poorly mixed pelagic habitat and producers in a well-mixed benthic habitat. Several basic ecological reproductive indices are rigorously derived for pelagic producers and benthic producers by analyzing nonnegative steady-state solutions. The possible scenarios of the asymmetric competition are explicitly formulated. The numerical bifurcation diagrams show that the environmental parameters affect the asymmetric competition and cause the regime switch between pelagic and benthic producers. The results reveal the role of spatial heterogeneity of pelagic producers and some characteristics of the asymmetric resource competition.
