In a community, the species present may be linked directly or indirectly through resources and consumption. More than 90 % of the fixed energy in terrestrial systems is processed autotrophically by plants and thus almost all terrestrial fauna depend on this production. Classically, in systems involving three trophic levels, such as plants, herbivores, and predators, a trophic cascade describes the positive top-down effects of the third trophic level on the biomass, richness, or composition of the producer species (see [1] and references therein). In a more recent and realistic approach, biodiversity is viewed and evaluated in ways that embrace the extrem
