2.2.4.1 Density independent model for organisms with discrete breeding season

2.2.4.1 Equation for density independent model for organisms with discrete breeding season

N_t+T=N_t + (T X r X N_t)

N_t=Population size at a particular time.

T=time in years.

r=intrinsic reproductive rate

N_t+T=Population size to the subsequent year

Plotting Nt against time depicts the population changes each year under density independent conditions.

The above Figure shows exponential increase of a population with discrete breeding season (Density independent model for organisms with discrete breeding season).
