Abstract
Community ecology is the study of interactions between species in a food web in a particular ecosystem. Early community ecology studies were often descriptive and focused on detailing how species interacted with each other. Within the last few decades community ecology has shifted to a more experimental nature, especially in aquatic systems that were amenable to experimentation or natural perturbations (Paine 1969; Carpenter et al. 1985; Estes et al. 2004). Through experiments, researchers showed the counterintuitive effects of species changes on the structure of entire food-webs. For example, the freshwater lake experiments of Carpenter (1985) showed dramatic effects of predator
