“…The effects of fire on insects and other arthropods can operate through a variety of mechanisms, and at different temporal and spatial scales. For instance, fire can have an immediate effect through direct mortality (Bock & Bock 1990), reducing species abundance (Andersen & Müller 2000;Sanders 2004) or on foraging activity (Araújo et al 2004). Fire is considered an important disturbance on ant communities in areas of fire regime, such as savannas across the world (Andersen & Müller 2000;Hoffmann 2003;Parr et al 2004).…”

“…This could sometimes happen in our survey, but most of the times we found that the activity ceased completely during the warmest hours of the day. Garcia (1997) in A. sexdens rubropilosa and Araujo et al (2004) in A. bisphaerica also noted a decline or a cessation of foraging activity in the warmest period of the day during the dry season and, at least for A. sexdens rubropilosa, a concomitant increase in excavation activity. We found a significant correlation between the level of activity of A. capiguara and air temperature.…”

The objective of this study was to investigate the seasonal change in the pattern of foraging activity in the leaf-cutting ant Atta capiguara and to provide an estimate of the annual herbivory rate of its colonies. We surveyed at least once a month during 12 months, the foraging activity of two colonies located in a pasture of central Brazil. Each survey consisted in counting the number of ants exiting and returning (laden or unladen) to their nests during 10 min every hour during 24 h. The air temperature and relative humidity were noted at the beginning of each survey. Independent of the season, the colonies presented two peaks of foraging activity, one small peak at the beginning of the day and another peak at the end of the day. During the dry season, the diurnal activity ceased almost completely between 10:00 and 16:00. The proportion of ants returning to the nest laden with a leaf fragment was also lower than during the humid season. Activity rhythm depended significantly on both air temperature and humidity: foraging activity peaked when the temperature was around 25°C and relative humidity around 66 %. Based on the statistical model used to describe the activity rhythm, we estimated that over a period of 1 year, the total dry biomass of vegetation collected by the two colonies studied was, respectively, 25.16 kg for the bigger nest, and 11.69 kg for the smaller one, or an equivalent of 104.83-kg and 48.71-kg fresh biomass, respectively.

“…This species was recorded only once in the pitfall traps in the unburned areas, but nests were often detected in unburned areas. The immediate mortality of colonies of an Acromyrmex species that builds nests on the soil surface occurs in uncontrolled fires in reforested areas (Araújo et al ). The absence of leaf‐cutting ants in the burned areas in our study area may be due to the soil dryness caused by greater sunlight exposure, which can hinder the development of the symbiotic fungus.…”

Fire is frequently used in the management of pastures in southern Brazil, but its effects on ground‐dwelling ant communities in Brazilian subtropical grasslands is still poorly understood. Here, we compared ant species richness and composition between periodically burned and unburned areas in native grasslands of the Atlantic Forest biome. In total, we found 35 epigeic ant species in burned and unburned areas. There was slightly higher species richness in burned than in unburned areas, independent of the sampling period (season). There was a significant difference in richness over the sampling period (season effect). Species composition varied significantly between the areas, in which nine species (26%) occurred only in burned areas, eight (23%) occurred only in unburned areas, and 18 (51%) occurred in both. Four species showed a significant preference for burned sites (Camponotus crassus, Linepithema humile and two undetermined species of Pheidole and Solenopsis). Although this study did not separate fire effects on ground‐dwelling ant communities (due to sampling design), it provides new information regarding subtropical native grasslands that can be used as a baseline for future studies.
