Jm. Beckers et Jcj. Nihoul, A SIMPLE 2 SPECIES ECOLOGICAL MODEL EXHIBITING CHAOTIC BEHAVIOR, Mathematical and computer modelling, 21(6), 1995, pp. 3-11
The classical prey-predator model of Lotka-Volterra is revisited. Inst
ead of constant growth rates, a modulated growth rate for the prey is
used. It is shown that in this very simple case, the resulting system'
s evolution may become nonlinearly resonant. This shows that complex b
ehaviour is not necessarily related to complex systems.
