Darwin's theory was strongly founded on the geographic distances traveled by migrating species, or occupied by their populations. A theory of "island biogeography" was introduced in 1967, further elaborating on importance of the distances traveled, or areas occupied by populations. A specialized field of "landscape ecology" concerns patches of habitat, and distances between them, along with movement corridors, or barriers to movement. With all of these, the individuals that move about and successfully reproduce in the population
