| description | Extrafloral nectaries (EFNs) and hemipteran honeydew are liquid food rewards (FRs) that encourage ant visitation in many plant families in a wide variety of habitats. In this study we explored the diversity, distribution and interactions of exudate-gathering ants at three different liquid food rewards: nectar from EFNs on Croton sarcopetalus and honeydew from the aphids Aphis spiraecola and Dysaphis foeniculus on Eupatorium hookerianum (Asteraceae) and Foeniculum vulgare (Apiaceae) respectively. For each FR we measured ant diversity and performed quantitative and qualitative comparisons among ants associated with the FRs. In addition, a linear regression was performed to test for possible associations between aphid and ant abundances in the case of honeydew FRs. Eight out of the 23 ant species found fed on both nectar from EFNs and honeydew from aphids, four of which fed at all FRs. Two ant species visited both aphid species and 13 were found exclusively at either one of the FRs. Brachymyrmex brevicornis was the most abundant ant species and Pheidole sp.2 had the greatest occurrence. Both ant species diversity and richness were higher at EFNs of C. sarcopetalus. Regressions showed positive significant association between ants and aphids abundances both on E. hookerianum and F. vulgare. We can conclude that the three liquid food rewards compared here showed modest similarity in their ant fauna. Furthermore, there was selectiveness of ants towards EFNs of C. sarcopetalus, which might be due to food source attributes rather than co-evolutionary factors. |

Los nectarios extraflorales (NEFs) y el melado excretado por hemípteros son fuentes de alimento (FsA) que favorecen la participación de hormigas en las interacciones mutualistas que establecen con las plantas y/o hemípteros. El objetivo de este trabajo fue estudiar, en una zona serrana del centro de la provincia de Córdoba, Argentina, la diversidad, distribución e interacción de hormigas melívoras en tres FsA diferentes: néctar de NEFs de Croton sarcopetalus (Euphorbiaceae) y melado de Aphis spiraecola y Dysaphis foeniculus en Eupatorium hookerianum (Asteraceae) y en Foeniculum vulgare (Apiaceae), respectivamente. En cada FA se contabilizaron e identificaron los áfidos y hormigasmelívoras presentes. Se obtuvo la riqueza y abundancia de hormigas y se calcularon los índices de diversidad de Shannon-Wiener y Sorenson (cualitativo y cuantitativo) para comparar las comunidades de hormigas en las diferentes FsA. Por último se realizó una regresión lineal entre la abundancia de áfidos y la abundancia de hormigas melívoras en las dos últimas FsA mencionadas, para determinar si las variables estaban asociadas. De las 23 especies de hormigas registradas, ocho (34.8%) se alimentaron tanto en NEFs como en las colonias de áfidos, de las cuales 4 spp. (17.4%) fueron encontradas simultáneamente en las tres fuentes. Además, dos especies de hormigas visitaron ambas especies de áfidos y 13 especies visitaron exclusivamente alguna de las FsA. Brachymyrmex brevicornis fue la especie más abundante, mientras que Pheidole sp.2 registró la mayor ocurrencia. Tanto la diversidad como la riqueza de especies de hormigas fue mayor en NEFs de C. sarcopetalus. Se encontró una relación positiva significativa entre la abundancia de áfidos y la abundancia de hormigas melívoras tanto sobre E. hookerianum como sobre F. vulgare. Podemos concluir que las tres FA estudiadas mostraron una similitud modesta en su fauna de hormigas. Además se observó selectividad por parte de las hormigas hacia los NEFs de C. sarcopetalus, que podría deberse a las características de la fuente de alimento más que a factores co-evolutivos.
