The population density of a particular insect species was determined to be 15,000 adults per hectare in the summer of 1996, 21,000 adults per hectare in the summer of 1997, and 29,400 adults per hectare in the summer of 1998.

What would you expect the insect population to be in the summer of 2000, assuming no change in λ?

dN/dt = rN (K-N/K ) The logistic equation above is used to describe the rate of change of a population, N, with time, t, Where r is the intrinsic rate of increase and K is the carrying capacity. What is value of per capita growth rate when population size is 200 individuals? ( K= 400, r =.25)
