“…Most of the available data on the impact of wildfire have been collected in the subtropics. Forest fires in the subtropics have been studied in relationship to communities of Hymenoptera (Potts et al 2003;Ratchford et al 2005;Tizón et al 2010;Cruz-Sánchez et al 2011;Mateos et al 2011;Arnan et al 2013;Lázaro-González et al 2013), Coleoptera and Lepidoptera (Elia et al 2012).…”

Forest fire remains among the most controversial topics in nature conservation. Here, we address changes in abundance and species composition of the bee and wasp community following a temperate forest crown fire that led to nearly complete defoliation and dieback of trees within 2 years. We found a highly dynamic community of 252 bee and wasp species (representing 18.8 % of total bee and wasp species known from the Czech Republic) that utilized 1-7-year-old burned forest stands. Species richness in the burned forest stands was significantly higher than that recorded in nearby forest that had been unaffected by any recent fire. The unburned forest hosted only 88 species. We found 42 red-listed species, of which 40 were present in the burned forest, while only 12 were present in the control forest. Numerous early-and late-responding species were detected, but maximum species diversity was reached 3 years after the fire. Only 7 of the total of 261 species were limited to the forest that was unaffected by any recent fire. A management regime that supported the presence of bare sand and heather patches, and removal of all but solitary pine trees, was found to be insufficient to support the full spectrum of forest fire-dependent species. This was mainly due to the absence of charred or decaying dead wood, which is otherwise utilized by numerous redlisted cavity adopters that are absent in the surrounding cultural landscape. Retaining part of the charred trunks is suggested as a novel post-fire conservation measure.

“…This result is directly related to modifications to the microclimate, which have mainly occurred due to the change in land use and loss of vegetation cover due to human settlements and agricultural and livestock activities (Halfter, 2011). When the physical environment is completely modified, the soil temperature increases, and humidity is lost; these changes lead to an increase in certain species, with numerical abundance in the colonies because they have high physiological tolerance to extreme and wideranging climates that are widespread (Rojas-Fernández, 2001;Tizón et al, 2010).…”

This investigation involved analyzing 77 publications, 6 national biological collections and an international collection and determining the myrmecological diversity of Tamaulipas, which consists of 195 species that belong to 60 genera, with 410 records in the state. The genera with the highest species richness were Camponotus Mayr (Formicinae), Pheidole Westwood (Myrmicinae) and Neivamyrmex Borgmeier (Dorylinae), with 17, 15 and 12 species, respectively. The ant fauna of Tamaulipas consists of 95% native species and 5% exotic species. The investigation determined that 25 municipalities had been sampled, and Gómez Farías, Victoria and Jaumave stood out with the highest number of ant species records; however, 18 municipalities that provide opportunities to increase the knowledge of Formicidae remain unexplored.

“…The disturbance indicator group could be considered a good management tool if the biology of the species that composes it was widely known. In this work, the group was made by grouping species or genera whose response to disturbances is documented (Folgarait, 1998;Tizón et al, 2010;Fuster, 2014;Villalba et al, 2014;Arcusa, 2016). In this way, it was possible to monitor the increase of these species and estimate the time of resilience.…”

Acacia melanoxylon is an invasive species of the mountain grassland of the southeastern part of the Buenos Aires province, Argentina. Fires are a natural disturbance, characteristic of the area, and favor the germination of this invasive plant. However, they are used as the first step in management systems for the Acacia species. Moreover, the use of ants in monitoring programs is very scarce for Argentina. The objectives of this work are: 1) to analyze the response and resilience capacity of native and invaded sites by A. melanoxylon after a fire for controlling this invasive species; 2) to detect groups of ants considered to be indicators of the recovery phase subsequent to the burning; and 3) to apply the concept of groups of disturbances, proposed by Roig and Espadaler, as an effective tool for monitoring. The sampling design consisted of three replicates of 10 pitfall traps for each environment, native and invaded. Ant species were grouped into functional groups, trophic guilds, and disturbance groups. The fire did not generate significant changes in the richness and abundance of ants in the mountain grassland. However, it generated a positive effect on the sites invaded by Acacia during the first year after the fire. The groups of minimum specialists of vegetation and the dominant Dolichoderinae are considered good bioindicators. Finally, the disturbance indicators can be considered reliable management tools if the biology of the species that compose it is known beforehand.

“…Soil compaction and cattle paths (the most important disturbance factors within the Zapotitlan Valley) may have a negative effect on the ant community, because soil compaction caused by cattle may prevent ants from building their nests underneath the soil surface and/or may destroy the nests already built by ants (Tizón et al, 2010). Moreover, disturbance factors have an indirect effect on ant behavior.…”

Abstract. Ants have been used as indicators of disturbííííance, because of their fast response to environmental changes. However, it is not well defined which disturbance factors are associated with specific changes on the ant community. We evaluated the effect of disturbance on the ant community in a xeric community from central Mexico. Two sites with contrasting levels of disturbance were chosen based on a quantitative index. We compared ant abundance, ant diversity and the main disturbance factors affecting the ant community. Also, we identified the bioindicator species of ants and the feeding guilds. Soil compaction and cattle paths were the most important factors of disturbance within the study sites. These factors probably affect the community of ants by preventing them from colonizing the surrounding vegetation as well as from nesting in the soil. Ant diversity was lower in the disturbed site than in the conserved one. Four ant species were identified as bioindicators of disturbance. Although functional diversity did not differ between sites, the guild of granivore ants was the most affected by soil compaction. This is of great importance because the foraging patterns of granivore ants determining the structure and other aspects of the plant community.

“…This allows for colonies to expand given a large supply of food resources, with colony growth ultimately restricted by local colony density and intraspecific competition (Taber 1998, MacMahon et al 2000. Harvester ants provide significant ecosystem services such as increased soil aeration via nest construction, altered plant species distribution through seed predation, and nutrient accumulation within and around their nest site (MacMahon et al 2000, Tizón et al 2010, Vieira-Neto et al 2016, Luna et al 2018. In addition to their ecosystem services, harvester ants are the main food source for the threatened Texas horned lizard (Phrynosoma Environmental Entomology, 52(3), 2023, 510-520 https://doi.org/10.1093/ee/nvad025 Advance Access Publication Date: 5 April 2023 Research cornutum) (Lombardi et al 2020).…”

With an increase in human population over the past 30 years, regional land use in south Texas has shifted from grassland and shrubland to a peri-urban matrix. Despite this shift from natural areas to more anthropogenically modified habitats, native red harvester ants (Pogonomyrmex barbatus) have maintained nest sites within parts of these matrices. To determine which habitat characteristics in a peri-urban landscape may play a role in red harvester ant nest site selection, we mapped the location of nests in 2020 and 2021. We then evaluated nest presence and absence relative to elevation, percentage of surrounding impervious surfaces, distance to roadways, and tree canopy cover (using NDVI). For a sub-sample of the study site, we also measured soil moisture and estimated the potential foraging area per colony with Voronoi tessellation. We found that nests were clustered together near high human-use areas such as athletic fields, lawns, sidewalks, and railroad tracks. Nests were more likely to be found in areas with higher elevation and lower tree canopy cover, with no impact from surrounding impervious surfaces or soil moisture. In fact, many nests were observed immediately adjacent to roadways and in paved parking lots. Red harvester ants are highly adept at nesting in disturbed, urbanized matrices, but still appear to be constrained by certain environmental factors like shading, potential flood risk (elevation), and access to food resources (foraging area).
