Diversity of social wasps (Hymenoptera: Vespidae) in Cerrado fragments of Uberlândia, Minas Gerais State, Brazil.
Studies of species survey are important to know the available natural resources and to get useful information about the ecological characteristics of a specific area. There are not studies, on this… Expand

Do ant visitors to extrafloral nectaries of plants repel pollinators and cause an indirect cost of mutualism
a b s t r a c t Plants and ants have widespread relationships that are commonly mediated by the offer of extrafloral nectar (EFN) to ants that protect plants against herbivores. However, these… Expand

Conditional outcomes in a neotropical treehopper-ant association: temporal and species-specific variation in ant protection and homopteran fecundity
Abstract We studied the association between the honeydew-producing membracid Guayaquila xiphias and its tending ants in the cerrado savanna of Brazil, during 1992 and 1993. Results showed that ants… Expand

Ant‐Homoptera Interactions in a Neotropical Savanna: The Honeydew‐Producing Treehopper, Guayaquila xiphias (Membracidae), and its Associated Ant Fauna on Didymopanax vinosum (Araliaceae)1
We investigate the ant fauna associated with the Neotropical treehopper, Guayaquila xiphias, on shrubs of Didymopanax vinosum in the cerrado (savanna) of SE Brazil. Treehoppers infested plants at the… Expand

Effect of herbivore deterrence by ants on the fruit set of an extrafloral nectary plant, Qualea
There are many definitions of extrafloral nectaries (EFNs), but those that define EFNs as nectaries that are not involved in pollination (e.g. Fiala & Maschwitz 1991) could be the most simple and… Expand

Influence of extrafloral nectary phenology on ant–plant mutualistic networks in a neotropical savanna
Temporal variation has been one remarkable feature of ecological interactions. In ant–plant mutualism, this variation is widely known, although little is understood about the mechanisms that shape… Expand

Ant-Homoptera interaction: do alternative sugar sources distract tending ants?
aggregations probably explains why ant tending levels remained unchanged in the presence of an alternate sugar source. The current experimental study and available field evidence from cerrado… Expand

Host–parasite interaction between branchiurans (Crustacea: Argulidae) and piranhas (Osteichthyes: Serrasalminae) in the Pantanal wetland of Brazil
Ecological studies of host–parasite interactions in the tropics are generally restricted to descriptive taxonomic aspects. The present study had as its objective identification of the metazoan… Expand

Loss and gains in ant–plant interactions mediated by extrafloral nectar: fidelity, cheats, and lies
All mutualistic plant–animal interactions are mediated by costs and benefits in relationships where resources (from plants) are exchanged by services (from animals). The most common trading coin that… Expand

Individual-Based Ant-Plant Networks: Diurnal-Nocturnal Structure and Species-Area Relationship
Despite the importance and increasing knowledge of ecological networks, sampling effort and intrapopulation variation has been widely overlooked. Using continuous daily sampling of ants visiting… Expand
