摘要

This paper provides a brief review of the biogeographic concepts of the renowned Swedish bio-geographer, zoologist, and limnologist Sven Petrus Ekman (1876-1964). He was the author of the first systematized treatise on historical marine biogeography (Ekman, 1935, 1953), in which he formulated the concept of the relict nature of contemporary tropical biotas derived from the Paleogene biota of the Tethys. Ekman (1915, 1920, 1935) proposed a biogeographic definition of the term "relict": a species (or genus, etc.) is relic to a region if it is isolated here from the main center of distribution and if its presence can only be explained by the fact that either it or its ancestral form were left behind under different environmental conditions than at present.
