1. The effects of two abundant ant species on soil nutrients and seedling recruitment in Brazilian Atlantic Forest
ABSTRACT Ants can influence soil fertility and the spatial distribution of seeds, with possible effects on seedling recruitment. The ant species Pachycondyla striata Fr. Smith, 1858 and Odontomachus chelifer (Latreille, 1802) co-occur in many forest areas in the Neotropics. We assessed soil fertility and seed bank structure in soil samples close and distant

2. Solution Inhibitory of Ant Nest (Myrmecodia Pendans) Extract on the Formation of Plaque in Children with Early Childhood Caries
Abstract Objective: To evaluate the effectiveness of gargling the solution of ant nest extract against plaque formation in children who experience Early Childhood Caries (ECC) when used as a mouthwash. Material and Methods: This study uses a pretest-posttest design with a control group. Thirty children with ECC, which were divided into three groups, namely

3. Peptidomic investigation of Neoponera villosa venom by high-resolution mass spectrometry: seasonal and nesting habitat variations
Abstract Background: Advancements in proteomics, including the technological improvement in instrumentation, have turned mass spectrometry into an indispensable tool in the study of venoms and toxins. In addition, the advance of nanoscale liquid chromatography coupled to nanoelectrospray mass spectrometry allows, due to its high sensitivity, the study of ve

4. First report of two species of scarab beetles (Coleoptera, Scarabaeidae) inside nests of Azteca cf. chartifex Forel (Hymenoptera, Formicidae) in Brazilian Amazonian Rainforest
ABSTRACT We report for the first time the occurrence of two species of scarab beetles, Phileurus carinatus declivis Prell, 1914 (Scarabaeidae: Dynastinae) and Cyclidius elongatus (Olivier, 1789) (Cetoniinae: Cremastocheilini) inside nests of Azteca cf. chartifex Forel, 1896, a neotropical arboreal ant species. This report indicates that these two beetle spec

5. Dynamics of the restoration of physical trails in the grass-cutting ant Atta capiguara (Hymenoptera, Formicidae)
ABSTRACT Dynamics of the restoration of physical trails in the grass-cutting ant Atta capiguara. Leaf-cutting ants of the genus Atta build long physical trails by cutting the vegetation growing on the soil surface and removing the small objects they find across their path. Little is known on the dynamics of trail construction in these ants. How much time do

6. Senescent stem-galls in trees of Eremanthus erythropappus as a resource for arboreal ants
Senescent stem-galls in trees of Eremanthus erythropappus as a resource for arboreal ants. Members of the dipteran families Tephritidae and Cecidomyiidae are inducers of stem-galls in Eremanthus erythropappus (DC.) MacLeish (Asteraceae), a tree common in the state of Minas Gerais, Brazil. When senescent, these galls become available to other organisms, such

7. Parasitoids of the endangered leafcutter ant Atta robusta Borgmeier in urban and natural areas
Parasitoids of the endangered leafcutter ant Atta robusta Borgmeier in urban and natural areas. Hosts of parasitoids in urban areas may suffer from a double threat of habitat destruction by urbanization and parasitism pressure. Moreover, the parasitoids themselves might be at risk if they are specialists. Here, we studied whether Atta robusta (Hymenoptera, F

8. Nível de dano econômico para formigas-cortadeiras em função do índice de produtividade florestal de eucaliptais em uma região de Mata Atlântica
The production and quality of eucalyptus plantations have been studied in areas with different densities of ant nests, being important to estimate losses caused by leaf-cutting ants. The effects of leaf-cutting ant on wood production in differents productivity sites were studied in eucalyptus plantations in the region of Atlantic Forest, Minas Gerais State,

9. Relocation of Croton sonderianus (Euphorbiaceae) seeds by Pheidole fallax Mayr (Formicidae): a case of post-dispersal seed protection by ants?
Although seed dispersal by ants might reduce seed predation near the parent plants, predation on discarded seeds clustered on nest refuse piles may reduce any initial benefit provided by seed removal. Here we examine the fate of Croton sonderianus seeds that were discarded by Pheidole fallax Mayr ants on their nest refuses in caatinga vegetation of northeast

10. Multiple queens in founding colonies of the neotropical ant Pachycondyla striata smith (Formicidae: Ponerinae)
In social insects, the typical mode of colony foundation occurs when a single queen is inseminated by a male and establishes a new colony, although we can find interspecific and intraspecific variations in queen number and queen-mating frequencies in a single colony. This study aimed to verify the queen number in Pachycondyla striata (Smith) colonies and to

11. Polietismo e expectativa de vida em operárias de Atta laevigata / Polyethism and lifespan in Atta laevigata workers
Age polyethism is the change in activities carried out by members of a colony during its life. Older individuals have lower future value to the colony, so it would be better for the colony if they could perform more dangerous tasks outside the nest and not return to its interior. Thus, the risk of bringing pathogens into the colony is reduced, protecting int

12. Efeitos da sazonalidade pluviomÃtrica sobre a diversidade e a composiÃÃo de uma assemblÃia de formigas (Hymenoptera: Formicidae) em uma Ãrea de caatinga / Effects of seasonal rainfall on diversity and composition of an assemblage of ants (Hymenoptera: Formicidae) in a caatinga
Presence of water is a determinant factor for food sources and/or nest sites availability, and is therefore potentially important for terrestrial invertebrate communities, particularly for those with fixed/perennial nests and that live in environments marked by strong rainfall seasonality. The aim of this work was to obtain informations about the seasonal pa
