Chapter 11 The Organization of Species Communities Summary

Ants coexist with many other species, and frequently these disparate species are organized into species communities. Frequently, species are found to be in direct competition with each other for resources. Ants commonly compete with other closely related ant species for nest sites, food, and foraging grounds. Competition strategies vary widely among species. Several types of competition are discussed.

General biological theory regarding competition, the role of dominant species, and conditions for species coexistence are discussed and applied to ants. Niche and density specialization are considered. Size differentiation and caste polymorphism are considered as factors in competition. Appeasement of competing species is discussed. Species-specific examples are provided for all strategies discussed.

Some interesting field studies on specific enemy identification are enumerated and summarized; "...at least some ant species have evolved defensive maneuvers directed in...
