Davidson et al. (1989)

General information

This study took place in 1985 and 1986, during September, October, and November. The authors surveyed variation in the ant associates of eight myrmecophytes of the tropical moist forests of western Amazonia.

Data type

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 interaction.
