The ecology and evolution of ant-plant interactions
- V. Rico‐Gray, P. Oliveira
- Environmental Science, Biology

The dynamics of ant-plant interactions are synthesized, including the sources of variation in their outcomes, to provide a better understanding of the unparalleled success of these two remarkable groups, of interspecific interactions in general, and, ultimately, of terrestrial biological communities.
The ecological function of extrafloral nectaries : herbivore deterrence by visiting ants and reproductive output in Caryocar brasiliense (Caryocaraceae)
- P. Oliveira
- Biology
- 1 June 1997
Ant-exclusion experiments with Caryocar shrubs revealed that ants significantly reduce the infestation levels by the butterfly Eunica bechina, the sucking bud Edessa rufomarginata, the bud-destroying fly Prodiplosis floricola and by a stem-galling wasp.
Ants affect the distribution and performance of seedlings of Clusia criuva, a primarily bird‐dispersed rain forest tree

This is the first study to demonstrate the combined effects of ants on the distribution and survival of seedlings of a primarily vertebrate-dispersed plant in a tropical forest.

Interactions between Fungus‐Growing Ants (Attini), Fruits and Seeds in Cerrado Vegetation in Southeast Brazil 1
- I. Leal, P. Oliveira
- Biology
- 1 June 1998
The results indicate that attine-frudseed interactions are particularly conspicuous in the cerrado, suggesting that fungus-growing ants may play a relevant role in fruitlseed biology in this vegetation type.

Foraging ecology of attine ants in a Neotropical savanna: seasonal use of fungal substrate in the cerrado vegetation of Brazil
- I. Leal, P. Oliveira

- 1 November 2000
The results indicate that lower attines present an opportunistic foraging behavior, by collecting items in the vicinity of their nests, and in accordance with the phenology of the cerrado vegetation.
Foraging ecology of the giant Amazonian ant Dinoponera gigantea (Hymenoptera, Formicidae, Ponerinae): activity schedule, diet and spatial foraging patterns
- V. Fourcassié, P. Oliveira
- Environmental Science
- 1 December 2002
The foraging ecology of D. gigantea is compared with other ponerine species living in tropical forests, as well as with other ant groups showing similar behavioural patterns.
