This chapter discusses the role of biotic areas in biogeography. A biotic area consists of homologous area relationships expressed by more than one monophyletic group that inhabits a common place and/or a designated endemic area. Relationships among biotic areas are recognized as area homologs and area monophyly. An area homolog is the smallest unit of meaningful cladistic relationship among areas. The chapter illustrates methods for discovering area homologies and area monophyly. Area homology is found by comparing area homologs among endemic areas to discover area monophyly or geographical congruence. Area homology, or area monophyly, is discovered when different areagrams are compared and their area homologs corroborate those of other areagrams.Less

Systematic biogeography, the discovery of classification of regions based on biotic area homologies, is a newly emerging method of biogeography that bridges phylogenetic and distribution patterns. This chapter reviews the history of area classification as it relates to the development of comparative biogeography, and introduces the notion of area relationship, known as area homology, which forms the basis of geographical congruence or area monophyly. The chapter focuses on the application of a systematic biogeography to demonstrate biotic area homology, and then explores mechanisms or processes that may have given rise to general patterns or expressions of area relationships.Less
