Predator prey population cycles
WebAs prey become scarce then the predator population size declines and the cycle starts again. These intuitive dynamics can be captured by one of the simplest mathematical descriptions of a predator–prey interaction: the Lotka–Volterra model … WebThus the predator and prey populations oscillate go in cycles. Starting with a low population of both predator and prey (in the region , ), at first the prey increase while the predators decrease (but not all the way to 0, because trajectories don't meet) until .
