A FAUNA DE FORMIGAS EM POVOAMENTOS DE EUCALIPTO E MATA NATIVA NO ESTADO DO AMAPÁ Acta Amazonica
OLIVEIRA,Marco Antonio de; DELLA LUCIA,Terezinha M. C.; ARAUJO,Márcio da Silva; CRUZ,Adalton Pinheiro da.
Um levantamento da fauna de formigas em uma área de mata nativa e em três plantações de Eucalyptus de 6, 20 e 106 meses de idade foi conduzido em agosto de 1992. Aamostragem consistiu de 2 transectos de 100 m por área, sendo que ao longo de cada transecto foram dispostas 10 armadilhas pitfall, que permaneceram no campo por 7 dias, após o que, foram substituídas por armadilhas contendo iscas de bolacha, sardinha e açúcar, que permaneceram na área por 1 hora para coleta das formigas. Além disso, para cada área foram feitas coletas manuais sobre o solo, senapilheira, árvores e arbustos por 5 horas não consecutivas.Um total de 121 morfoespécies, distribuídas em 5 subfamílias e 50 gêneros foram coletados. Os índices de Hill calculados indicam que na mata nativa...

Albuquerque,Nicolas Lavour de; Brandão,Carlos Roberto Ferreira.
In the first paper of this series (Albuquerque & Brandão, 2004) we revised the Vezenyii species group of the exclusively Neotropical solenopsidine (Myrmicinae) ant genus Oxyepoecus. In this closing paper we update distribution information on the Vezenyii group species and revise the other Oxyepoecus species-group (Rastratus). We describe two species (Oxyepoecus myops n. sp. and O. rosai n. sp.) and redescribe previously known species of the group [O. daguerrei (Santschi, 1933), O. mandibularis (Emery, 1913), O. plaumanni Kempf, 1974, O. rastratus Mayr, 1887, and O. reticulatus Kempf, 1974], adding locality records and comments on the meagre biological data of these species. We also present an identification key to Oxyepoecus species based on workers.

Abundance and diversity of soil arthropods in olive grove ecosystem (Portugal): effect of pitfall trap type IPB - Escola Superior Agrária
Santos, Sónia A.P.; Cabanas, J.E.; Pereira, J.A..
Soil arthropod biodiversity is an indicator of soil quality and can be studied using pitfall trapping. In this research, olive grove edaphic fauna was assessed at different sampling dates by comparing two different diameters (7 and 9 cm) and three different contents (empty, water and preservative) of pitfall traps in order to determine which type of pitfall trap is more efficient. Considering all pitfall trap types and sampling times, a total of 12,937 individual edaphic arthropods belonging to 11 taxa were recovered. Smaller traps with preservative collected significantly more individuals than the other pitfalls tested. Larger and empty traps collected significantly more spiders and traps with preservative collected more beetles. Smaller and empty traps...

Ant community richness and composition across a gradient from Eucalyptus plantations to secondary Atlantic Forest Biota Neotropica
Suguituru,Silvia Sayuri; Silva,Rogério Rosa; Souza,Débora Rodrigues de; Munhae,Catarina de Bortoli; Morini,Maria Santina de Castro.
Secondary forests and exotic tree plantations are expanding across tropical landscapes. However, our current understanding of the value of these human-dominated forest landscapes for invertebrate biodiversity conservation is still very poor. In this paper, we use the leaf-litter ant fauna to assess invertebrate diversity in one commercially managed Eucalyptus plantation (four years old), two abandoned plantations of different regeneration ages (16 and 31 years), and one neighboring secondary Atlantic Forest in Southeastern Brazil. There was a clear gradient in species richness from the secondary forest to the managed Eucalyptus plantation; richness and diversity peaked in secondary forest and in the older regenerating Eucalyptus plantation. Significantly...

Ant species distribution along a topographic gradient in a "terra-firme" forest reserve in Central Amazonia. Repositório Alice
OLIVEIRA, P. Y. de; SOUZA, J. L. P. de; BACCARO, F. B.; FRANKLIN, E..
Abstract ? In Amazonia, topographical variations in soil and forest structure within "terra-firme" ecosystems are important factors correlated with terrestrial invertebrates' distribution. The objective of this work was to assess the effects of soil clay content and slope on ant species distribution over a 25 km2 grid covering the natural topographic continuum. Using three complementary sampling methods (sardine baits, pitfall traps and litter samples extracted in Winkler sacks), 300 subsamples of each method were taken in 30 plots distributed over a wet tropical forest in the Ducke Reserve (Manaus, AM, Brazil). An amount of 26,814 individuals from 11 subfamilies, 54 genera, 85 species and 152 morphospecies was recorded (Pheidole represented 37% of all...

Ant species (Hymenoptera, Formicidae) from the seasonally dry tropical forest of northeastern Brazil: a compilation from field surveys in Bahia and literature records Rev. Bras. entomol.
Ulysséa,Mônica A.; Brandão,Carlos R. F..
Ant species (Hymenoptera, Formicidae) from the seasonally dry tropical forest of northeastern Brazil: a compilation from field surveys in Bahia and literature records. The Caatingas occur predominantly in northeastern Brazil and comparatively it is the biome that received less attention than any other ecosystem in Brazil, representing the region where invertebrate groups are less known. We present here the first list of ant species of the Caatingas, compiling information from the literature, from a study of samples preserved in alcohol in the Laboratory of Entomology (Universidade Estadual de Feira de Santana), and from a field survey conducted in Milagres, Bahia, submitting standardized 1-m² samples of the leaf-litter to Winkler extractors. Summing all...

Antibacterial properties of contact defensive secretions in neotropical Crematogaster ants J. Venom. Anim. Toxins incl. Trop. Dis.
Quinet,Y; Vieira,RHSF; Sousa,MR; Evangelista-Barreto,NS; Carvalho,FCT; Guedes,MIF; Alves,CR; de Biseau,JC; Heredia,A.
Crematogaster ants use their contact venoms to compete with other ants. Although those venoms are used primarily as repellent and toxic secretions, they may have other functions. The present study aimed to test the antibacterial property of abdominal venom of three neotropical Crematogaster ant species (C. distans, C. pygmaea and C. rochai) against gram-negative (Escherichia coli and Pseudomonas aeruginosa) and gram-positive (Enterococcus faecalis and Staphylococcus aureus) bacteria. Sterile filter paper was soaked with C. distans, C. pygmaea or C. rochai crude venom and placed on an agar dish that was inoculated with bacterial suspensions. The agar dish was incubated overnight at 37ºC and examined for zones of growth inhibition. For each tested venom and...

Arthropod recolonization in the restoration of a semideciduous forest in southeastern Brazil Neotropical Entomology
Pais,Mara P; Varanda,Elenice M.
The use of arthropods for monitoring habitat changes has grown widely in the last decades. In Brazil, however, most of the studies in restored areas have involved only vegetation changes. The present study aimed at investigating recolonization patterns of epigeic arthropods in recently restored sites of semideciduous forests in southeastern Brazil. We compared the community structure of adjoining sites 5, 17, 29 and 36 months old with that at a nearby forest remnant (reference site). We also determined the most abundant species and looked for ecological indicator species of each site age. Arthropods were sampled using pitfall traps, and their assemblages were described and compared with multi- and univariate statistical methods. Species abundance and...

As formigas como indicadores biológicos do impacto humano em manguezais da costa sudeste da Bahia Neotropical Entomology
Delabie,Jacques H.C.; Paim,Valéria R.L. de M.; Nascimento,Ivan C. do; Campiolo,Sofia; Mariano,Cléa dos S.F..
Os manguezais são comuns ao longo dos estuários da costa Atlântica do Brasil. Embora a diversidade de plantas seja baixa, esse ecossistema suporta uma fauna diversa, oferecendo diferentes tipos de recursos para numerosos organismos não aquáticos. Muitos insetos habitam as áreas de manguezal e, entre estes, numerosas espécies de formigas exclusivamente arbóreas. Na maior parte das áreas do mundo onde ocorrem, os manguezais vêm sofrendo altos níveis de impacto humano e isso é particularmente evidente no Sudeste da Bahia, onde ocorre o tradicional extrativismo de caranguejos e peixes, aterramento com fim de exploração imobiliária e corte de lenha. A comunidade de formigas de 13 manguezais com diferentes níveis de antropização foi estudada na costa sudeste da...

Attractiveness of copperleaf-based bait to leaf-cutting ants Ciência Rural
Nagamoto,Nilson Satoru; Barbieri,Rafael Forti; Forti,Luiz Carlos; Cardoso,Sandra Regina de Sousa; Moreira,Sinara Maria; Lopes,Juliane Floriano Santos.
Leaves of copperleaf (Acalypha spp.) are greatly accepted by leaf-cutting ants and therefore used to maintain colonies in the laboratory. In order to determine the attractive potential of granulated bait of Acalypha wilkesiana leaves versus citrus pulp, currently used in commercial baits, an evaluation was performed, by using the leaf-cutting ant Atta sexdens rubropilosa as model. The handmade non-toxic baits contained powder (90% w/w) of either citrus pulp or A. wilkesiana were offered simultaneously in the foraging arena until the total loading of one of them. Results showed that copperleaf baits are less attractive than the citrus ones, which invalidates the viability of the substitution.

Avaliação rápida da diversidade de formigas em sistemas de uso do solo no sul da Bahia Neotropical Entomology
Braga,Danielle L; Louzada,Júlio N C; Zanetti,Ronald; Delabie,Jacques.
We aimed to compare the soil ant diversity in different land use systems from Atlantic Forest area, in Southern Bahia state, Brazil. The ants were sampled in 16 sites: two primary forest sites (un-logged forest); three young secondary forests (<8 years old); three intermediate secondary forests (8-20 years old); three old secondary forests (&gt;20 years old); three Eucalyptus grandis plantations (3-7 years old), and two introduced pastures. Each site was sampled in three sampling points 15 m apart, and distant over 50 m from the site edge. In each sampling point we gathered the litter from a 1 m² and extracted the ants with Winkler extractors during 48h. We found 103 ant species from 29 genera and eight subfamilies. The five richest genera were...
