Robert R. Junker, Curtis C. Daehler, Stefan Dötterl, Alexander Keller, and Nico Blüthgen. 2011. Hawaiian ant–flower networks: nectar-thieving ants prefer undefended native over introduced plants with floral defenses. Ecological Monographs 81:295–301.

Appendix G. Potential links encountered in the 10 habitats, nectar tube width, head capsule width, olfactometer results, and nectar palatability.

TABLE G1. Potential links encountered in the ten habitats. Accessibility: 1 = Nectar holder tube width > head capsule width; 0 = Nectar holder tube width < head capsule width. Mechanical barrier: Other structures that prevent ants from consuming nectar additional to accessibility. Palatability: 1 = nectar offered outside flowers accepted by ants; 0 = nectar not accepted. In cases where an ant and plant species occurred in two or more habitats, the mean value of Rij und Qij are given.
