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 sedentary habits. Much is known about the chemistry of these soils, yet their zoology has been neglected. Hence, we characterized soil fertility, macroinvertebrate communities, and their activity at nine archeological sites in three Amazonian regions in ADEs and adjacent reference soils under native forest (young and old) and agricultural systems. |

ABSTRACT We report new records of Gnamptogenys caelata Kempf (1967) and Gnamptogenys minuta (Emery, 1896) from Brazil. We also describe Gnamptogenys piei n. sp. from Southeast Brazil. This distinctive new species is known only from a single worker found in leaf litter from montane forests of the Mantiqueira mountains in Itatiaia National Park, Rio de Janeiro State, Brazil. The specimen was collected at 1991 m above sea level, an infrequent altitude for minuta-group ants, usually more common at lower altitudes. The new species is imaged, compared with other minuta-group species, and an updated identification key for all known species of the minuta-group is included. |

Behavioral studies of birds have reported several functions for active anting. Maintenance of plumage and prevention from ectoparasites are some examples. In this context, anting by males may be of particular importance in a classical lek mating system, where male-male competition is common and individuals with higher fitness may be more successful at attracting of females. In the present note, I describe the anting behavior of White-bearded Manakin (Manacus manacus) and I relate it to lek breeding and feeding (frugivory) habits of the species. Males used up to seven Solenopsis sp. ants. They rubbed each small ant from 4 to 31 times on undertail feathers until the ants were degraded; ants were not eaten. Males then searched for a new ant in the court.... |

Canopies of the locally occurring Amazonian tree species Calophyllum brasiliense. Camb. (Guttiferae, height 10 m) were fogged after dawn on the same day at five adjacent localities in a 20-year-old plantation at the Adolpho Ducke Forest Reserve near Manaus/Brazil, using natural pyrethrum (0.5%, 1.0%, 1.5%), Baythroid (0.3%) and diesel oil, respectively. The 1152 ants collected represented 52 species, 17 genera and five subfamilies. The highest number of ant species was obtained with the synthetic pyrethrum Baythroid 0.3% and with natural pyrethrum 1.5%. About 46% of the total ant species were only collected in the first hour after fogging, and 17% only during the second hour, after trees had been heavily shaken. About 73% of the total ant specimens dropped... |

The genus Pachycondyla is a large group of ants in the Ponerini tribe, known mostly from tropical and subtropical regions. Pachycondyla sennaarensis, the so-called Samsum ant in the Middle East, is distributed throughout the African tropics, Arabian Peninsula and Iran, where it is responsible for many cases of insect-induced dermal lesions and systemic reactions in humans. Populations of P. sennaarensis were studied in two regions of Iran and some aspects of their biology, ecology and medical importance are herein presented. Colonies of P. sennaarensis contain less than 850 workers that live in complicated underground galleries approximately one meter deep. Because of the harsh weather conditions of southern Iran, they can survive only in human disturbed... |

Community of ants that nest in dead twigs on the ground of Central Amazonian forest, Brazil. A total area of 2,880 m² in four forest sites, near Manaus, Brazil, was searched for ant colonies nesting in dead twigs on the ground. An amount of 3,706 twigs (0.5-5 cm in diameter) were gathered, of which only 623 (16.8%) had ants, which is equivalent to a density of 0.22 nests per m². Seventy species have been found. The predominant genera were Pheidole (Westwood), Crematogaster (Lund), and Solenopsis (Westwood). For most species, many of the nests found had only workers and brood, suggesting that colonies either use multiple twigs to nest or do not live exclusively in the twigs, using other types of substrate (e.g., leaf-litter, soil, fruit pods) to nest. Most... |

Resumo: A proliferação de formigas saúvas (Atta spp.) nos agroecossistemas é preocupante, uma vez que causam redução da produtividade ou mesmo inviabilizam a produção agrícola, sendo um grande gargalo para muitos agricultores. Devido à carência de dados mais sólidos na literatura referente a técnicas agroecológicas de controle, vêm sendo testadas algumas práticas no Sítio Agroecológico da Embrapa Meio Ambiente, localizada em Jaguariúna (SP). Esta experiência consiste em um conjunto de medidas, tais como: disponibilizar no entorno outras fontes de alimento para as formigas, cujo ataque não resulte em perdas econômicas; bloqueio físico dos olheiros próximos, para inibir e atrasar o trabalho das formigas; e o uso de extratos repelentes. Neste relato... |

The diet of anuran species is based on a large variety of prey items, which may be related to the availability of prey in the environment. In Amazonia, studies on the diet of anurans have occurred mainly in primary forests. Because forest fragmentation promotes changes in the environment, it is expected that the diet of anuran species will also be affected. Here we describe the diet composition of anurans captured in a forest remnant at Fazenda Amoty, municipality of Plácido de Castro, state of Acre, Brazil. Stomach contents of 34 specimens of Allobates femoralis (Aromobatidae), Adenomera hylaedactyla, Engystomops freibergi (Leptodactylidae), Rhinella sp. (Bufonidae), and Elachistocleis muiraquitan (Microhylidae) had 877 prey items belonging to 19 prey... |

Ants are considered an important group of invertebrates in terrestrial ecosystems, where they participate in important ecological processes between animals and plants, and they are considered good indicators of environmental impacts as well. Although the diversity of ants in the Amazon biome is already relatively well known, the ant fauna in the state of Acre, Brazil is still poorly known. The aim of this study was to carry out a survey of ants in a forest remnant located in the municipality of Plácido de Castro, Acre, using pitfall traps. Thirty-six species of ants were collected from six subfamilies and 18 genera. From the species confirmed, 11 (Cephalotes serraticeps, Gnamptogenys moelleri, Gnamptogenys triangularis, Neoponera apicalis, Neoponera... |

As formigas são consideradas um dos grupos de invertebrados mais importantes dos ecossistemas terrestres, participando de importantes processos ecológicos entre animais e plantas, além de serem indicadas como bons organismos de impactos ambientais. Entretanto, a fauna de formigas do estado do Acre ainda é pobremente conhecida. Neste sentido, o objetivo deste trabalho foi realizar um levantamento de formigas utilizando armadilhas do tipo "pitfall trap" em um remanescente florestal localizado no município de Plácido de Castro, AC. |

This is the first study of isoenzyme variability in the leaf-cutting ants (Myrmicinae, Attini) Acromyrmex heyeri (Forel, 1899) and A. striatus (Roger, 1863) which are common throughout the southern Brazilian state of Rio Grande do Sul. We studied the alloenzyme variability of malate dehydrogenase (MDH), alpha-glycerophosphate dehydrogenase (alpha-GPDH) and amylase (AMY) in 97 colonies of A. heyeri and 103 colonies of A. striatus. Five loci were found for these enzyme systems, one locus (Amy-1) being monomorphic in both species and four loci (Mdh-1, alpha-Gpdh-1, Amy-2, and Amy-4) being polymorphic. For each species there were exclusive alleles for the Mdh-1 and Amy-2 loci and differences were also found in the allele frequencies for the other polymorphic... |
