François Pierre La Varenne employed "chouxfleurs" in "Le cuisinier
The Theory of Island Biogeography in the Florida Keys. The islands were fumigated to clear the arthropod populations. Immigration of species onto the island was then observed in a first and second year census. Wilson and Simberloff confirmed that there was an inverse relationship between the number of species on an island and the distance to the source region as predicted in "The Theory of Island Biogeography". MacArthur and Wilson's theory of island biogeography has been widely applied outside of island ecosystems. For microbiota, the theory has been applied to the distribution of ectomycorrihzal fungi on trees, the distribution of bacteria in water-filled treeholes, and
