1. Temporal variation in the composition of ant assemblages (Hymenoptera, Formicidae) on trees in the Pantanal floodplain, Mato Grosso do Sul, Brazil
Temporal variation in the composition of ant assemblages (Hymenoptera, Formicidae) on trees in the Pantanal floodplain, Mato Grosso do Sul, Brazil. In this paper we investigate how seasonal flooding influences the composition of assemblages of ants foraging on trees in the Pantanal of Mato Grosso do Sul. During the flood in the Pantanal, a large area is cove

2. Influência do desenvolvimento florestal sobre a comunidade edáfico-epígea de Arthropoda e a mirmecofauna: bases para a bioindicação do processo sucessional na restauração ecológica / The influence of forest development on edaphic and epigeic Arthropod communities and ant fauna: bases for bioindicantion of successional process in ecological restoration
A restauração ecológica visa o estabelecimento de ecossistemas semelhantes aos que originalmente ocupavam uma determinada área que foi degradada. Todavia, os resultados dos esforços envolvidos na restauração e no retorno dos processos ecológicos naturais são difíceis de serem medidos, pois faltam métodos apropriados. Os bioindicadores são ferrame

3. Geographical transition zone of Solenopsis fire ants (Hymenoptera: Formicidae) and Pseudacteon fly parasitoids (Diptera: Phoridae) in the state of São Paulo, Brazil
Solenopsis saevissima (Smith) and Solenopsis invicta Buren are the most abundant and widely distributed fire ants in Brazil. The occurrence of the two fire ant species and of their parasitoids Pseudacteon spp. is described for a climatic and phytophysiognomic transition area in the state of São Paulo. Both fire ant species have a parapatric distribution, ap

4. Do leaf-litter attributes affect the richness of leaf-litter ants?
The search for factors shaping leaf-litter ant communities has received particular attention due to the essential role of these insects in many ecological processes. Here, we aimed to investigate how the number of leaves and leaf morphotypes affect the litter-ant species density at forest edge and interior in an Atlantic Forest remnant in the state of Alagoa

5. Epigean ant communities in Atlantic Forest remnants of São Paulo: a comparative study using the guild concept
Comunidades de formigas epígeas em remanescentes da Mata Atlântica do Estado de São Paulo: um estudo comparativo utilizando o conceito de guildas. As guildas constituem-se em uma valiosa ferramenta ecológica, pois permitem realizar comparações entre ambientes em diferentes condições. As formigas podem ser utilizadas como indicadores ecológicos, prin

6. Partição da diversidade de formigas em uma paisagem fragmentada / Ant diversity partitioning in a fragmented landscape
Forest fragmentation events have been characterized as one of the main threats to biodiversity in modern times, and are the primary cause of species loss in tropical forests. Ants are organisms that present many suitable traits to be used in ecological studies, therefore they are frequently used in fragmentation surveys. However only epigaeic microhabitat ha

7. 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

8. Interações ecológicas em Malpighiaceae no cerrado: compartilhamento de guildas de herbívoros e variações nos resultados da interação formiga-planta / Ecological interactions in Malpighiaceae in the Cerrado: sharing of guilds from herbivores and variations in the results of ant-plant interaction
Ecological interactions represent essential tools for a better understanding of natural communities, having in animal-plant relationships important models for study. For that, become needful phenological analyses of plants, capable of demonstrating the flowering strategies and with it the ways of temporal organization of resources available for herbivores. T

9. Ant community structure in Neotropical savannas: a test of generality contrasting Brazil and Australia / Estrutura de comunidades de formigas em savanas arbóreas tropicais: um teste da generalidade de padrões ecológicos contrastando Brasil e Austrália
The aim of this study was to compare ant community structure between the savannas of Brazil and Australia. The study was conducted in woodland savanna areas nearby Darwin, in northern Australia, and Uberlândia and Caldas Novas in central Brazil. The sampling design consisted of eight 400 m line transects, four in each continent, with eight pitfall traps and

10. Determinants of ant communities in Restinga / Determinantes de comunidades de formigas em restinga
O litoral brasileiro apresenta aproximadamente 9.200 quilômetros de extensão, das quais 5.000 km são ocupados por ecossistema de Restinga. Este ecossistema é um conjunto de formações vegetacionais que se desenvolvem em dunas e cordões arenosos do período Quaternário dentro do domínio da Floresta Atlântica. As espécies de plantas que ocorrem em Re

11. BIODIVERSITY OF LEAF-LITTER ANTS IN THE BODOQUENA MOUNTAIN RANGE NATIONAL PARK MATO GROSSO DO SUL BRAZIL / BIODIVERSIDADE DE FORMIGAS DE SERAPILHEIRA DO PARQUE NACIONAL DA SERRA DA BODOQUENA MS
This study represents the first systematic Formicidae survey in the Bodoquena Mountain Range National Park state of Mato Grosso do Sul - Brazil. We have compared two distinct areas in domain of Deciduals Forests along the Bodoquena mountain range with 10 sites: 5 in the north portion and 5 in the south portion. Our first goal was to describe the leaf-litter

12. RESPOSTAS DA COMUNIDADE DE FORMIGAS (HYMENOPTERA: FORMICIDAE) AO ECÃTONE EUCALIPTO-FLORESTA SECUNDÃRIA EM TRÃS PAISAGENS DE MINAS GERAIS / Responses of ant community (Insecta: Hymenoptera) to the eucalyptus-secondary forest ecotone in three landscapes of Minas Gerais.
The borders or ecotones have deep effects upon the dynamics of species and communities in man-modified landscapes With the amplification of rates of forest clearing and patching many species are exposed to these border habitats The highest exposition to borders influences the individualâs movement through the landscape the interaction among species the trop
