“…Overall, ant species richness in our study was low compared to other grassland areas in the Pampa biome in southern Brazil (Rosado et al 2013), in the Brazilian Cerrado (Andrade et al 2007) and in tropical savannas in Africa (Parr et al 2004) and Australia (Andersen 1991;Gunawardene & Majer 2005), but it was similar to that found in a semi-natural grassland in Japan (Hosoishi et al 2015) and higher than that found in other grasslands in southern Brazil (Diehl et al 2005), in grasslands in northeastern Argentina (Calcaterra et al 2010) and in the Grand River Grassland in the USA (Moranz et al 2013). The low vegetational complexity along with high altitudes and low temperatures in this region, especially in winter, when frost occurs with some frequency and snow also sometimes occurs, seem to be the key factors influencing species richness in these highland fields.…”

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.

“…High predation levels by ants are observed during warm weather (Weseloh 1988; Ennis & Philpott 2019), as cold conditions reduce foraging (Rosado et al . 2013). Also, wasps generally increase foraging activity during these seasons (Kasper et al .…”

“…During dry–warm conditions, ant species occurrence increases (Ennis & Philpott 2019) but seems to be reduced in cold conditions (Rosado et al . 2013). Thus, there is a dynamic process in the neotropical climate where alterations of dry–wet conditions affect not only butterfly ecology but also natural factors of mortality.…”

Season and weather affect the mortality of immature stages ofAscia monusteorseis(Lepidoptera: Pieridae) caused by natural factors

In this study, we evaluated the causes of mortality in immature stages of Ascia monuste orseis Godart 1918 (Lepidoptera: Pieridae) over each of four seasons, for 2 years, on an experimental cabbage plot using life tables. We addressed two key questions: (1) Do the mortality rates caused by a factor vary by season? And (2) how does the local weather contribute to such variation? We identified five causes of mortality (failure, pathogens, parasitism, predation and rainfall) that together tended to be higher during wet–warm conditions with values up to 94%. However, each cause and its mortality rate varied among seasons. Failure was observed in all stages and tended to increase during cold conditions with a negative relationship with air temperature and relative humidity and positive for precipitation. Larval and pupal predation increased during warm conditions and was positively associated with both air temperature and relative humidity. Conversely, in seasons with intense precipitation, pupal predation was reduced and had a negative relationship. Rainfall caused mortality of eggs and larvae, mostly during intense events, and egg mortality also showed a positive and significant association with precipitation. Larval parasitism was low, and pathogens were noted in larvae and pupae, but we did not find variation by season for these factors. Our results indicate that mortality caused by failure, predation and rainfall on immature stages of A. monuste orseis can vary among seasons and appear to be related to local weather. These findings improve our comprehension of how local weather affects the immature stages of a neotropical pest and the associated mortality factors.

“…litter is significant in the maintenance of species diversity and richness (Magura et al, 2000). Depending on issues at hand, both Families thus have the potential to be used as environmental indicators due to their close abundance, diversity and close relation with habitat quality, (Peck et al, 1998;Magura et al, 2000;Andersen et al, 2002;Raino, 2012;Rosado et al, 2013). Determination of the use of these insect as indicators, however, needs further assessment over longer term to ascertain their sensitivity to change as well as their response to these changes within specific environments (Peck et al, 1998).…”

Heterogenous agroecosystems have the capacity to maintain high insect diversity despite alterations due to human activities. The distribution of carabid beetles and ants within a variety of habitat mosaics was monitored at two climatically distinct locations. Both insect Families were monitored to compare community similarities between habitats, within and between the two sampling locations. Species occurrences were significantly different between the two locations (p<0.05), with distinct patterns of distribution, resulting in high dissimilarity between locations and habitats sampled. While the lowveld had highest populations and diversity of both ants and carabid beetles in unmanaged habitats, the middleveld had high carabid beetle diversity in managed habitat and populations in unmanaged habitat, while ant populations and diversity were highest in an unmanaged habitat. Although the two locations had no carabid beetle species in common, they had a few ant species in common. Due to their abundance, diversity and relation to management, both insect Families have the potential to be used as indicators in the locations assessed..
