Geographic Spread of Gnamptogenys triangularis (Hymenoptera: Formicidae: Ectatomminae)
Gnamptogenys triangularis (Mayr), native to the forests of South and Central America, is a predatory ant that feeds on millipedes. In its native range, this species is known from Buenos Aires, Argentina (38.1°S) in the south to Costa Rica (10.4°N) in the

A new putative species in the Ectatomma ruidum complex (Formicidae: Ectatomminae) produces a species-specific distress call [PDF]
Social insects communicate by using chemical, visual, tactile, and acoustic signals, including stridulations. Ectatomma ruidum is a mainly Neotropical ant species complex that has faced strong divergence at the genetic level; the species have a highly ...

Ecological change and conflict reduction led to a social circulatory system in ants. [PDF]
Behavioral innovations can be ecologically transformative for lineages that perform them and for their associated communities. Many ecologically dominant, superorganismal, and speciose ant lineages use mouth-to-mouth social regurgitation behavior ...

Morphological traits, such as size and shape, may reflect a combination of ecological and evolutionary responses by organisms. Ants have been used to evaluate the relationship between the environment and species coexistence and morphology. In the present

Temporal polyethism, life expectancy, and entropy of workers of the ant Ectatomma vizottoi Almeida, 1987 (Formicidae: Ectatomminae) [PDF]
We investigated the changes in the behavioral repertoire over the course of life and determined the life expectancy and entropy of workers of the ant Ectatomma vizottoi.

Extrafloral nectar as entrée and elaiosomes as main course for ant visitors to a fireprone, mediterranean-climate shrub. [PDF]
Thousands of flowering plants produce both extrafloral nectaries on their leaves and seeds with nutrient‐rich appendages. Their possible interaction was examined in an Australian shrub here and shown that their co‐presence serves to attract ants to the plant throughout the year that then take the seeds from the plant to their nests during the flowering

The role of body mass in limiting post heat-coma recovery ability in terrestrial ectotherms. [PDF]
Under global warming, animal species show shrinking body size responses to heat. We found that heat‐comatose ants were suffering high predation pressure and thus were ecologically dead. Ants with small mass, however, were more thermal resilient and likely to recover from heat‐coma as compared to larger species, providing an explanation for the decrease
