The contribution of Ch. Darwin to invasion eco logy is discussed. Darwin considered biotic invasions as complex but integral phenomena involving ecological, biogeographical, evolutionary, taxonomic and other aspects, such as patterns of past and present distribution, means and pathways of dispersal (and dispersal limitations), struggle for existence and natural selection, phylogenetic relationships of taxa, environmental factors, and evolutionary changes. All modern hypotheses explaining biotic invasions are evolutionary in their nature. Darwin outlined not one naturalization hypothesis but at least three invasion concepts, which may be considered as precursors of modern theories/hypotheses of biotic invasions. Thus, Darwin established foundations for all following evolutionary and ecological studies of biotic invasions, including several currently debated invasion concepts, such as Escape from Enemies, Empty Niche, Species Richness, and Disturbance hypotheses. It is demonstrated that Dar winian explanations of invasions are based on the balance between biotic/abiotic factors and ecological interactions.
