Biol 2260 population dynamics and growth - 22/09/16. Geometric and exponential population growth population growing at maximum rate produce characteristic j-shapes curve due to density dependence some populations grow geometrically, others exponentially. : average number of offspring left by an individual during one time interval. If you have three years, you would cube it. Exponential growth dn/dt = rmaxn : this form of the equation for exponential population growth expresses the rate of population change as a product of rmax and n nt. = n0ermax1 :the integrated for of the equation for population growth calculates population size. Invasive species: colonization after the glaciers retreated. Conditions for exponential growth for exponential growth you need: favourable environments and low population densities. Slowing of exponential growth: when the population size is less than predicted by the exponential model, then it suggests that the population has slowed.
