Note regular periodicity, and lag by lynx population peaks just after hare peaks
The birth and survival rates of the predators depend on their available food supply—namely, the prey.Predator-prey systems
r - prey growth rate : Malthus law
m - predator mortality rate : natural mortality
a and b predation coefficients : b=ea
e prey into predator biomass conversion coefficient
The time t is measured in months.
