| Description
| - Climate change is predicted to not only cause shifts in the latitudinal and altitudinal distribution of species, but also changes in trophic interactions. Studying changes in herbivory and herbivore and predator pressure along altitudinal gradients may assist our understanding of the complex trophic interactions and their responses to future climate change. As part of the IBISCA-Queensland Project, we tested the hypothesis that ant predation pressure influences the abundance of herbivores which in turn influences herbivory in the understorey of subtropical rainforest and that these relationships are modified by altitude. We used the occupancy of ants at tuna baits as a measure of predation pressure, herbivorous beetles as representatives of herbivores, and the extent of damage to mature leaves as a measure of herbivory. Ant predation pressure was the greatest at 300 m above sea level and declined with increasing altitude but only at ground level. In contrast, ant predation pressure on understorey foliage was not related to altitude and was always much lower than that on the ground. Neither altitude nor ant predation pressure at ground or understorey levels significantly influenced the abundance of herbivorous beetles.
