This study was done in the Central
Amazonian rainforest, north of Manaus, Amazonas, Brazil from June
through August in 1990. The main objectives were to quantitatively
describe the ant-myrmecophyte matrix, to search for patterns of
compartmentalization, and to compare the results from the ant-plant
system with those from other mutualistic systems.
The authors recorded their data by
counting the number of visits of each ant species to each plant
species. Data are presented as an interaction frequency matrix, in
which cells with positive integers indicate the frequency of
interaction between a pair of species, and cells with zeros indicate no
