Biodiversity/Evolution

Are there any examples of the competitive exclusion principle

how species diversity can affect the ecosystem’s stability At the regional scale diversity increases because of introduction of new species, although work in our lab comparing invasions and extinctions in coastal ecosystems has shown that the composition of the biota has changed in important qualitative ways. Specifically, scientist find that extinctions occur mainly at the level of high-order predators and other carnivores, whereas invasions are dominated by species at lower trophic levels like suspension feeders and detritivores.
