Introduction
Rodrigo M. Feitosa developed his research experience on systematics, natural history, and conservation of ants (Insecta, Hymenoptera, Formicidae). Current projects include systematic studies of different groups of Neotropical ants, with emphasis on the ectatommine genera. Additional interests include ant surveys in unexplored Neotropical ecosystems, the development of collectiing and processing techniques of ant samples, and the building of an exhaustive database of Brazilian ants.

Apresentamos de forma condensada informações básicas sobre esses temas que a maioria dos mirmecólogos (as pessoas que estudam formigas) devem conhecer. Muita informação importante ficou de fora, mas esse viés foi proposital. Foi a única forma que encontramos para enfatizar as chaves de identificação e os gêneros de formigas da forma que merecem, ma...

Due to their widespread distribution, range of adaptations, local abundance, and species diversity, ants are a major component of terrestrial communities worldwide. However, such high ecological prevalence is not shared among all ant lineages, with four ant genera – Camponotus, Pheidole, Strumigenys, and Crematogaster – accounting for a disproporti...

Uncovering the evolutionary history of the subfamilies Ectatomminae and Heteroponerinae, or ectaheteromorphs, is key to understanding a major branch of the ant tree of life. Despite their diversity and ecological importance, phylogenetic relationships in the group have not been well explored. One particularly suitable tool for resolving phylogeny i...
Article
Despite the historical efforts to list and organize the taxonomic knowledge about the Brazilian ant fauna, the most diverse in the world, several gaps regarding species distribution data and sampling coverage persist. In an attempt to fill some of these gaps, we here apply a scientometric approach to provide an updated overview of the ants of Brazi...
Article
Scientometric investigation and scientific production analysis are essential for science progress. Although a vast number of studies on Brazilian ant diversity have been carried out, a critical analysis of the advances in its scientific production is still missing. We compiled a comprehensive database on ant diversity papers carried out in the Braz...

Article
The division of labor into sterile and reproductive castes in social insects is often reflected in marked morphological differences, which might have played an important role in the remarkable adaptive success of these organisms. Some ant lineages have undergone further morphological differentiation, with the evolution of differences within the wor...

In 1887, Mayr described four species of the ant genus Strumigenys collected in the Brazilian state of Santa Catarina: Strumigenys unidentata, Strumigenys subedentata, Strumigenys denticulata, and Strumigenys crassicornis. All of them were described based on a series of one to several specimens, without designation of a holotype, as usual at that ti...

Ants, an ecologically successful and numerically dominant group of animals, play key ecological roles as soil engineers, predators, nutrient recyclers, and regulators of plant growth and reproduction in most terrestrial ecosystems. Further, ants are widely used as bioindicators of the ecological impact of land use. We gathered information of ant sp...

Monitoring restoration practices is an expensive process, but essential to verifying their success. One way to reduce sampling costs is using biodiversity indicators, a term used for a functional or taxonomic group that is in agreement with another group. The objective of this work was to evaluate the agreement between the richness and composition...

Acrostichum danaeifolium, a Neotropical fern, occurs preferentially in marshy areas or at the margins of lakes and mangroves. Microlepidoptera larvae burrow through the petioles of the fern, preferentially on the non-expanded leaves. The galleries in the petiole create a new microhabitat, harboring a rich fauna of arthropods. The aim of the present...

The diversity of endotherms and ectotherms may be differently affected by ambient temperature and net primary productivity (NPP). Additionally, little is known about how these drivers affect the diversity of guilds of different trophic levels. We assessed the relative role of temperature and NPP in multitrophic guilds of ectothermic (arthropods: an...

In the south of Brazil, grasslands are naturally widespread over two different biomes, the Pampa in the southernmost region and within the Atlantic Forest in the northern portions. The natural grasslands of the state of Paraná comprise a very particular physiognomy composed of two distinct formations: the Campos Gerais and the grasslands of the sou...

Amazonian rainforests, once thought to be pristine wilderness, are increasingly known to have been widely inhabited, modified, and managed prior to European arrival, by human populations with diverse cultural backgrounds. Amazonian Dark Earths (ADEs) are fertile soils found throughout the Amazon Basin, created by pre‐Columbian societies with sedent...

Ants use their mandibles for a wide variety of tasks related to substrate manipulation, brood transport, food processing, and colony defense. Due to constraints involved in colony upkeep, ants evolved a remarkable diversity of mandibular forms, often related to specific roles such as specialized hunting and seed milling. Considering these varied fu...

Tropical ants experience intense intra- and interspecific competition for food sources, which influences their activity pattern and foraging strategies. Even though different ant species can coexist through spatial and temporal niche partitioning, direct competition for food cannot be avoided. Recruitment communication is assumed to help colonies t...

The year 2020 marked the centenary of the birth of the German-Brazilian myrmecologist, Dr. Frei Walter Wolfgang Franz Kempf, O.F.M., (1920-1976), whose remarkable research contributed greatly to the advancement of the taxonomy of Neotropical ants, especially in Brazil. This post is a tribute to mark his centenary and to recognize the relevance of h...

A challenge for studies on the organization of ant assemblages in forest ecosystems is to disentangle the causal effects of species occurrences. The structural and functional attributes of trees can act as environmental filters for ground-dwelling ant species influencing resource availability and the microclimate. The biotic interactions, especiall...

Despite the outstanding diversity and ecological relevance of social insects in most terrestrial ecosystems, current knowledge of these insects in the Atlantic Forest is still somewhat dispersed in literature. In this chapter, we offer an overview covering the origin, evolution, diversity, functional composition, and distribution of all the eusocia...
Article
Almost three centuries since Linnaeus introduced the system of binomial classification[1], thousands of species new to science are still described every year[2]. Any research dealing with living organisms is intrinsically dependent on taxonomy for reproducibility, since misidentifications may affect conclusions[3]. As such, published taxonomic resu...

Habitat loss is a leading cause of extinctions, which may occur even before species are recorded or formally described. On the other hand, limitations in species distribution data and sampling biases can hamper inferences about patterns of species richness that form the basis of conservation strategies. Insects, despite their crucial roles in terre...

Several studies have characterized and delimited subterranean ant assemblages. Soil extraction, one of the methods employed to access this fauna, employs the removal of monoliths. One of the most widely used methods for the extraction of soil sampling is called TSBF (developed by the Tropical Soil Biology and Fertility Programme). This method provi...

The extensive occupation of canopy trees by ants can be attributed to many factors, such as the presence of structures that provide food and shelter. Structures induced by other insects in host plants, like senescent galls, can provide shelter and a nesting place for many species of ants. The main objectives of this work were: (1) to describe the a...
