As part of your Fish & Wildlife job, you measure some populations and find the following: the competitive effect of trout on pike minnows equals 1.25, the competitive effect of pike minnows on trout equals 0, the per capita growth rate of pike minnows equals 0.25, and the per capita growth rate of trout equals 0.5. The carrying capacity of a species equals the number of available nesting sites. Currently, the environment contains 500 nesting sites. You devise a way to introduce artificial nesting, which only pike minnows can use. If you introduce these artificial nesting sites (leaving the trout nesting sites at 500), how many will you need for the pike minnow’s population to grow?
