Removing lianas from trees resulted in a 35% reduction in ant species richness, primarily limiting broad-ranging specialist predators. Connecting trees with ropes mitigated the loss of ant species observed following liana removal. Lianas also provide nest sites for arboreal ants; however, addition of nest sites had little effect on ant communities in trees with and without lianas. These results suggest that anticipated increases in liana abundance in tropical forests will likely increase local ant species richness and shift ant species composition. Photo credit: Benjamin J.
