Exercise 9

African annual killifish live in temporary pools, where their populations survive the dry season as eggs that lie dormant in the mud, developing and hatching only when the pools fill each wet season. In contrast, the guppy, a common aquarium fish, lives in populations consisting of mixed-age classes in which reproduction occurs year-round. Which model of population growth, exponential or geometric, would be most appropriate for each of these fish species?
