Microclimatic Patterns in the Army Ant Bivouac

Abstract

which varied with the habitat. The species associated with cantaloupe changed in kind and number as decomposition progressed. Forty-eight species were shown to be attracted to cantaloupe. Fish was like cantaloupe in that it underwent a definite course of decay in each habitat and that the associated species changed in kind and number as decomposition progressed. Seventy-seven species were shown to be attracted to fish. A comparison of the species of arthropods shown to be attracted to fish and cantaloupe in each habitat with those shown to be attracted to the same materials in the other habitats shows that Habitats I and II had more species in common than any other two habitats. Similarly Habitat III was more closely related to I and II than to IV, but had more species in common with IV than did I and II. Of the four habitats, Habitat IV had fewest species and the smallest percentages of these in common with other habitats. When all 444 species collected during the study
