Parapatric and parapatry are terms from biogeography, referring to organisms whose ranges do not significantly overlap but are immediately adjacent to each other; they only occur together in the narrow contact zone, if at all. Such organisms are usually closely related (e.g. sister species), their distribution being the result of parapatric speciation.
