Rather overshadowed by his more famous Nobel laureate father Svante Arrhenius, a chemist, Olof Arrhenius nevertheless made at least one important discovery for which he continues to be known. In 1921 he published the results of an analysis in which he counted the number of species occurring in different-sized plots and then set the results to a mathematical formulation, thereby deriving the species-area relation (one of the many uses of which includes the design of protected areas). Arrhenius worked in other areas as well, publishing a total of over two hundred articles on subjects as widely varied as soil science, sugar beet cultivation, plant growth, history of science, and metals corrosion.
