The authors designed a field experiment to test the hypothesis that competitive interactions between the closely related A. segrei (an introduced species) and A. carolinensis (a native species) would cause a change in the perch height of A. carolinensis . What aspects of the experimental design were used to help rule out potentially confounding variables? Select all that apply. Six islands were studied. A. sagrei was introduced on three of the islands, and the other three islands were used for comparison. The perch height of both species was measured multiple times over the three years that scientists conducted the experiment. Islands of three different sizes were selected (2 large, 2 medium, and 2 small) and the same experiment was run on each pair of islands. The non-native species A. segrei was introduced on three islands by the scientists to observe its effect on A. carolinensis . Before A. segrei was introduced on three islands, perch height data of undisturbed A. carolinensis on those islands was collected.
