Explaining the Abundance of Ants in Lowland Tropical Rainforest Canopies
The extraordinary abundance of ants in tropical rainforest canopies has led to speculation that numerous arboreal ant taxa feed principally as “herbivores” of plant and insect exudates. Based onExpand

The role of resource imbalances in the evolutionary ecology of tropical arboreal ants
Abstract In numbers and biomass, ants (Hymenoptera, Formicidae) often dominate arthropod faunas of tropical rainforest canopies. Extraordinary ant abundance is due principally to one or a few speciesExpand

Ecological Studies of Neotropical Ant Gardens
In a census taken in Peru's Manu National Park, 10 epiphytic angiosperms from seven plant families established principally on arboreal carton-ant nests. These "ant gardens" (AGs) were most oftenExpand

Granivory and competition as determinants of annual plant diversity in the Chihuahuan desert
In the Chihuahuan Desert of southeastern Arizona, we monitored the responses of three seasonal classes of annual plants (winter, summer and biseasonal species) to experimental removal of seed-eatingExpand

Granivory in the Chihuahuan Desert : interactions within and between trophic levels
We investigated the effects of Chihuahuan Desert granivores on three seasonal classes of plant resource species, the effects of these resource classes on one another, and the way in whichExpand
