For the metapopulation of Daphnia in Scandinavian freshwater pools, which situation would be most likely to result in maintenance of the metapopulation, rather than its extinction?
A) Immigrants increase the genetic diversity of pools, slightly increasing r.
B) Years of drought decrease the average size of all pools.
C) Small pools “wink off” and are not repopulated by dispersal from larger pools.
D) The pools are mostly small, and there is no dispersal among them.
E) Dispersal among pools is infrequent, and many pools reach zero density.

Natural selection favors DDT-resistant mosquitoes that are already present in a population when DDT exposure occurs. Competition for limited resources causes mosquitoes to migrate to geographical areas that have richer supplies of DDT. A population of 1.492 finches is intróduced to a rainforest.
