Consequences of Ratio-dependent Predation for Steady-state Properties of Ecosystems'

  title={Consequences of Ratio-dependent Predation for Steady-state Properties of Ecosystems'},
  author={Lev R. Ginzburg},
Ratio-dependent and prey-dependent models of trophic interactions make very different predictions about the steady-state (equilibrial) properties of ecosystems, such as the response of equilibrium abundance and biomass of organisms in each trophic level to increased primary productivity or nutrient input. Prey-dependent heory predicts alternating positive, negative, and zero responses of trophic levels to increased productivity, whereas ratio-dependent theory predicts proportional increase in… CONTINUE READING
