What will be an ideal response?
In a long term study by the evolutionary biologists Endler and Reznick, they illustrated the effect of predation on life history traits by studying guppies with different predators: cichlids and killifish. The killifish preys mostly on immature, smaller guppies and cichlids pursue mature, larger guppies. They noticed that in river portions with only killifish, the guppies were larger than in
river portions with only cichlids. In an experiment, the researchers put the smaller guppies that had previously lived only with cichlids (which eat large guppies) in a river portion that only had killifish (which eat smaller ones). a. What did they observe over the course of eleven years? b. What do you predict would happen if they performed the opposite experiment and mixed guppies from killifish river portions to a river with only cichlids?
