All but one species of large birds native to New Zealands tropical forests are now extinct. Numbers of the one surviving species, the kereru (Hemiphaga, novae seelandine), are declining rapidly due to habitat loss, poaching, predation, and interspecies competition that wiped out the other native birds. The keruru is the only remaining dispersal agent for several native tress that produce big seeds and fruits, mainly because it is the only remaining species that can swallow big fruits (left) and expel big seeds whole. One of these trees, the puriri (Vitex lucens), is New Zealands most valued hardwood. Explain, in terms of natural selection, what would happen to puriri trees in New Zealand if the kereru becomes extinct.
Figure 45.10b If the major food source of the seals declines due to pollution or overfishing, which of the following would likely occur? The carrying capacity of seals would decrease, as would the seal population. The carrying capacity of seals would decrease, but the seal population would remain the same. The number of seal deaths would increase but the number of births would also increase, so the population size would remain the same. The carrying capacity of seals would remain the same, but the population of seals would decrease.
