“…Considering the growing need for inventories to fill knowledge gaps about the diversity of places that need to be given conservation prior-ity, regional species lists are an important tool (Castro et al, 2018;Demétrio et al, 2017;Vicente et al, 2018). The primary data generated by the inventory of animal and plant species are very important in decision-making regarding environmental conservation management.…”

Piauí, a Brazilian Northeast state, has been considered one of the most important regions for the presence of new taxa in ants globally, especially considering the ecosystems’ diversity formed by the transition of the three biomes in the state, the Cerrado, Caatinga and the Atlantic Forest. Despite the recent increase in studies of ant diversity in the Neotropical region, Piauí still represents a major knowledge gap regarding its ant fauna. Therefore, this study aimed to increase the knowledge about the ant fauna of the state by generating a list of species with data obtained from the literature, online repositories and collection expeditions to the Serra da Capivara and Serra das Confusões National Parks. A total of 152 species in 52 genera and nine subfamilies were registered from 24 localities in Piauí. Fifty-eight out the 152 species recorded represent new records for the state, eight are new records for the Brazilian Northeast Region, and one consists of a new record for the country. Eleven species are here recognized as new for science. Considering the field expeditions carried out here, this work represents the first standardized study for the ant fauna of Piauí. The species list presented considerably exceeds the current number of species registered for the state so far. From the present 48 records, the number of species for Piauí raises to more than 150 with a tendency to increase with the accomplishment of future field endeavors and advances in the study of the local ants.

“…For Colombia, a total of 43 species of army ants were previously reported, thirteen of them in the department of Amazonas (Pérez et al 2009, Castro et al 2018, Fernández et al 2019, Palacio 2019. Our sampling brings the number of species to 44 in Colombia and 17 for Amazonas.…”

“…Previous studies have described the army ant diversity in the Colombian Amazon region. For example,Castro et al (2018) sampled 71 sites in thirteen municipalities and three departments (Caquetá, Putumayo and Amazonas), covering a wide altitudinal range in the Andean-Amazon transition zone, and reported four species of army ants (C. andicola, Eciton hamatum, L. praedator and Neivamyrmex cf. hetschkoi).…”

Amazonian indigenous territories as reservoirs of biodiversity: The army ants of Santa Sofia (Amazonas – Colombia)

The Amazon basin is undergoing processes of global change that threaten one of the planet’s greatest sources of biological and cultural richness. Among different conservation strategies, indigenous reserves play a key role by reducing the impact of factors such as the deforestation caused by the expansion of the agricultural frontier. Despite the demonstrated importance of these indigenous territories, there is a lack of studies evaluating their contribution to the regional diversity in Colombia, especially for invertebrate groups. By surveying indigenous territories for the first time in the Amazonas department, we investigated the army ant fauna inhabiting different land use types: forests; “chagras” in different stages of regeneration; and pastures. In a sampling plot that represents just 0.0014 % of the department’s area, four genera and eight army ants species were recorded, representing 47 % of known species in the Amazonas department and 18 % in Colombia. Our sampling revealed three new records for the department and Neivamyrmex diana as a new record for the country. Mature forests harbored six species, while the chagras system retained up to five species. Notably, when placing our results in a national context, we revealed several country regions and departments (e.g., Córdoba, Sucre, Vaupés) that presented limited or no information on army ant diversity. Our results provide justification for the continuous evaluation, monitoring and conservation of indigenous reserves, based not only on their demonstrated cultural and ancestral importance but to their potential to retain high biodiversity.

“…Despite the fact that the lowest soil macrofauna richness and density were observed in the degraded pasture, the soil engineers (Isoptera, Formicidae and Oligochaeta) exhibited higher densities that the other taxonomic groups. Formicidae are usually very abundant in deforested areas [38,93,94], with many species commonly reported in agricultural and urban ecosystems [95]. Earthworms are resistant towards degraded soils [31,61] and can change soil physical properties and biogeochemical processes [96].…”

Soil Quality Restoration during the Natural Succession of Abandoned Cattle Pastures in Deforested Landscapes in the Colombian Amazon

Successional processes in abandoned pastures in the Amazon region have been well-documented for the floristic component; however, soil succession has been poorly studied. This study assessed the physical, chemical and biological responses of soils in the Amazon region during the natural succession process in two main landscapes of the Colombian Amazon. Soil data on soil physico–chemical (bulk density, macroaggregates, pH and minerals) and biological (soil macrofauna) composition were evaluated along chronosequence with four successional stages: (i) degraded pastures, (ii) young (10–20-year-old), (iii) middle-age (25–40-year-old) and (iv) mature forests, in two different landscapes (hill and mountain). Individual soil variables and a synthetic indicator of soil quality (GISQ) were evaluated as tools for natural succession monitoring. The results corroborated the negative impact that cattle ranching has on Amazon soils. After 10 years of natural succession, the physico–chemical and biological soil components were widely restored. Less soil compaction and organic carbon occurred in older successional stages. Soil macrofauna richness and density increased along the chronosequence, with an evident association between the macrofauna composition and the macroaggregates in the soil. None of the individual soil properties or the GISQ indicator discriminated among natural succession stages; therefore, new soil quality indicators should be developed to monitor soil quality restoration in natural successions.
