Imagine two new volcanic islands spring up in the middle of the ocean. Each island is quickly founded by a few individuals of a species of ground-nesting bird that requires very dry land (with little rain) to thrive. The two islands differ in rainfall, one wetter and one drier. Assuming that rainfall determines carrying capacity for these birds, and that rainfall is consistent over time, what might the growth curves for the bird populations look like over many years for the two islands?
