Ant (Dolichoderinae) are known to selectively grow species of epiphytic "Squamellaria" (Rubiaceae) which produce large domatia inside which the ant colonies nest. The ants plant the seeds and the domatia of young seedling are immediately occupied and the ant faeces in them contribute to rapid growth. Similar dispersal associations are found with other dolichoderines in the region as well. Another example of this type of ectosymbiosis comes from the "Macaranga" tree, which has stems adapted to house colonies of "Crematogaster" ants. Many tropical tree species have seeds that are dispersed by ants. Seed dispersal by ants or myrmecochory is widespread and
Carpenter ant an individual carpenter ant to be recognized as a nestmate, it must, as an adult, go through specific interactions with older members of the nest. This process is also necessary in order for the ant to recognize and distinguish other individuals. If these interactions do not occur in the beginning of adult life, the ant will be unable to be distinguished as a nestmate and unable to distinguish nestmates. Recognition allows for the presence of kin-specific interactions, like kin altruism. Altruistic individuals increase other individuals' fitness at the expense of their own fitness. Carpenter ants perform altruistic actions toward their
