Ecology

Facilitation: When there us facilitation, earlier colonizing species facilitate the growth of future species in some way. If there was a removal of earlier colonizing species, then the species that they facilitate may have a harder time existing. Inhibition: When inhibition is taking place earlier colonizing species are inhibiting the growth of future species. If the earlier successional species are removed, then the species that they were inhibiting would be more likely to grow. Tolerance: If neither inhibition or facilitation are occurring then tolerance is occuring. This means that species are tolerating condition. Their survival depends more on their life history strategies than on facilitation or inhibition of earlier species. Thus, if earlier successional species were removed, then only species that can tolerate the ecological conditions will survive there.
