Ecological succession is the reason why different types of ecosystems either disappear, or they are born new within a specific environment. Some frog species have left the ancestral aquatic habitat and ventured into terrestrial and arboreal ones. Although researchers have long acknowledged that variation among species influences the surrounding environment, only recently has evidence accumulated for the ecological importance of variation within species.
