Conditional outcomes in a neotropical treehopper-ant association: temporal and species-specific variation in ant protection and homopteran fecundity
TLDR
This is the first study to simultaneously demonstrate conditionality in ant-derived benefits related to both protection and fecundity in an ant-tended Membracidae, and the first to show the combined action of these effects in the same system.
Diversity of social wasps (Hymenoptera: Vespidae) in Cerrado fragments of Uberlândia, Minas Gerais State, Brazil.
TLDR
The diversity of species found in fragments of the cerrado region in Uberlândia, MG, and their temporal distribution showed that in order to carry out a wasp survey, a combination of different collection methodologies seems to be more appropriate.
Influence of extrafloral nectary phenology on ant–plant mutualistic networks in a neotropical savanna
TLDR
It can be concluded that the phenology of EFNs is one effective mechanism shaping the temporal variation of two properties of an ant–plant interaction network.
Loss and gains in ant–plant interactions mediated by extrafloral nectar: fidelity, cheats, and lies
TLDR
It is proposed that ant–EFN bearing plant interactions serve an excellent and unique model to test the “Geographic Mosaic Theory” of coevolution providing a more clear view of how evolution has structured these plant–animal ecological networks.
Effect of herbivore deterrence by ants on the fruit set of an extrafloral nectary plant, Qualea
TLDR
The role of EFNs acting against herbivores is still under discussion, and plants bearing EFNs may account for up to 31% of the woody individuals and 25% in the cerrado community of Brazil (Oliveira & Oliveira-Filho 1991).
Individual-Based Ant-Plant Networks: Diurnal-Nocturnal Structure and Species-Area Relationship
TLDR
It is observed that diurnal and nocturnal ant-plant networks exhibited the same pattern of interactions: a nested and non-modular pattern and an average level of network specialization, and it is possible that in some cases processes shaping mutualistic networks formed by protective ants and plants may be underestimated by diurnal sampling alone.
Ant‐Homoptera Interactions in a Neotropical Savanna: The Honeydew‐Producing Treehopper, Guayaquila xiphias (Membracidae), and its Associated Ant Fauna on Didymopanax vinosum (Araliaceae) 1
TLDR
Investigation of the ant fauna associated with the Neotropical treehopper, Guayaquila xiphias, on shrubs of Didymopanax vinosum in the cerrado (savanna) of SE Brazil finds 21 ant species harvesting honeydew at G. xiphia aggregations, far greater than that reported for any other ant‐homopteran system.
Ant-Homoptera interaction: do alternative sugar sources distract tending ants?
TLDR
The current experimental study and available field evidence from cerrado vegetation do not support the prediction that ants would neglect honeydew-producing homopterans in the presence of extrafloral nectaries.
Differences among ant species in plant protection are related to production of extrafloral nectar and degree of leaf herbivory
TLDR
