General information

This describes de ant-plant interaction network in the rainforest at the Australian Canopy Crane in Cape Tribulation, Far North Queensland, Australia (16°07' S, 145°27' E, 80 m a.s.l.) and adjacent forests within 5 km radius of the crane site, including patches of open secondary forest. Counts of ant colonies attending extrafloral (EFN) and floral nectaries (FN) are provided, as well as independent abundance estimates for ant colonies based on sugar bait experiment (from Blüthgen and Fiedler 2004). Ants with zero abundance are those not recorded during bait experiments. For plants, number of plant individuals on which any insect were recorded on nectaries given as abundance estimate. Plant life forms: cl = climber, he = herb, sh = shrub, tr = tree, pa = palm. 

Data type

Frequency of interaction was estimated as the number of ant individuals of a particular species collected on a 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.
