Abstract: Many studies have shown that ant communities respond to changes in the environment. However some questions remain unanswered. What ant functional groups dominate different types of ecosystems? What groups succeed one another? Are there trends in the succession of ant communities in relation to vegetation succession? To answer these questions, data analysis of studies from six ecosystems, viz. tropical rain forest, montane forest, temperate forest, desert, subtropical grassland, tropical bushland, was performed. I showed that each habitat had different dominant functional groups. In tropical rain forests, Opportunist and Tropical Climate Specialist functional groups thrived in young, disturbed vegetation. These two groups were succeeded by Cryptic Species, Generalized Myrmicinae and Specialized Predator groups during vegetation succession. Sigmoidal mathematical models best described the decline and growth of these two communities, respectively. I was able to demonstrate this pattern of succession within a secondary tropical rain forest in Singapore.
