Q1. An ecologist studying desert plants performed the next experiment. She staked out two identical plots that included a few sagebrush plants and numerous small annual wildflowers. She found the same five wildflower species in similar numbers in both plots. Then she enclosed one of the plots with a fence to keep out kangaroo rats, the most general herbivores in the area. After two years, four species of wildflowers were no longer present in the fenced plot, but one wildflower species increased dramatically. The unfenced control plot had not changed significantly in species composition. Using concepts discussed what do you think happened?
