Match the scenarios described to the main kind of isolating mechanism that they illustrate. In each case, viable hybrid zygotes can be produced between the species in the laboratory by artificial insemination, but hybrids between them are rarely or never encountered in nature. Two insect species live in the same region, but they feed and mate on different species of plants. A. Habitat isolation B. Copulatory isolation C. Hybrid inviability Two lizard species live in the same region, but one mates in the evening just after dusk and the other mates in the morning around dawn. Two frog species live in the same region, but hybrids between them have mating calls that neither the hybrids nor individuals of the parent species respond to. D. Mechanical isolation E. Sexual isolation F. Gametic isolation G. Behavioral sterility Two snail species live in the same region, but one coils in the opposite direction from the other, so mating does not occur even if courtship is initiated. H. Temporal isolation
