The Lotka-Volterra predator-prey model with foraging-predation risk trade-offs
Original language description
This article studies the effects of adaptive changes in predator and/or prey activities on the Lotka-Volterra predator-prey population dynamics. The model assumes the classical foraging-predation risk trade-offs: increased activity increases population growth rate, but it also increases mortality rate. The model considers three scenarios: prey only are adaptive, predators only are adaptive, and both species are adaptive. Under all these scenarios, the neutral stability of the classical Lotka-Volterra model is partially lost because the amplitude of maximum oscillation in species numbers is bounded, and the bound is independent of the initial population numbers. Moreover, if both prey and predators behave adaptively, the neutral stability can be completely lost, and a globally stable equilibrium would appear.
Czech name
Vliv adaptivního chování na Lotka-Volterrův model dravce a jeho kořisti
Czech description
V práci se studuje klasický model populační dynamiky dravce a jeho kořisti za předpokladu, že kořist i dravec maximalizují svoji fitness. Model předpokládá, že zvýšení aktivity vede k vyššímu příjmu potravy a současně k vyššímu riziku predace. Model predikuje, že adaptivní chování vede k částečné či úplné stabilizaci Lotka-Volterrovy populační dynamiky.
