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. Termite assemblages (Blattaria, Isoptera) in two montane forest (Brejo de Altitude) areas in northeastern Brazil
Resumo: Enclaves de floresta úmida de altitude nos domínios da Caatinga, localmente conhecidos como "Brejos de Altitude", estão associados a áreas com mais de 500 m de altitude e às chuvas orográficas. O presente estudo teve como objetivo caracterizar a estrutura da taxocenose de térmitas em duas áreas de Brejo de Altitude localizadas nos municípios

3. Diversidade de cupins (insecta, isoptera) em brejos de altitude: variação espacial, influência de fatores ambientais e similaridade com domínios morfoclimáticos brasileiros.
As estruturas taxonômica e trófica das taxocenoses de cupins foram estudadas em dez áreas de Brejo de Altitude, estabelecidos nos domínios da Caatinga, buscando analisar os padrões de riqueza e distribuição das espécies. Para cada área, foi aplicado um protocolo padronizado de amostragem (30 horas x pessoa), consistindo de cinco parcelas de 5 x 2 m

4. How much can the number of jabiru stork (Ciconiidae) nests vary due to change of flood extension in a large Neotropical floodplain?
The jabiru stork, Jabiru mycteria (Lichtenstein, 1819), a large, long-legged wading bird occurring in lowland wetlands from southern Mexico to northern Argentina, is considered endangered in a large portion of its distribution range. We conducted aerial surveys to estimate the number of jabiru active nests in the Brazilian Pantanal (140,000 km²) in Septembe

5. Efecto de los cortafuegos sobre el ensamble de hormigas (Hymenoptera, Formicidae) en una región semiárida, Argentina
In arid and semiarid regions, the presence of roads or firebreaks can affect microclimatic variables that influence the abundance of soil nesting ants. We studied ant nest density in environments with different soil types (loose and compacted soil), and vegetation cover (shrubland, grassland and bare soil) south of Caldenal, La Pampa, Argentina. We selected

6. 15d-PGJ2 modulates acute immune responses to Trypanosoma cruzi infection
The acute phase of Trypanosoma cruzi infection is associated with a strong inflammatory reaction in the heart characterised by a massive infiltration of immune cells that is dependent on the T. cruzi strain and the host response. 15d-PGJ2 belongs to a new class of anti-inflammatory compounds with possible clinical applications. We evaluated the effects of 15

7. Hyper abundant mesopredators and bird extinction in an Atlantic forest island
Islands can serve as model systems for understanding how biological invasions affect native species. Here we examine the negative effects of mesopredator mammals on bird richness at Anchieta Island, an 826 ha offshore island in the coast of Brazil. Anchieta Island has the highest density of mammals of the entire Atlantic forest, especially nest predators suc

8. ASPECTOS DA BIOLOGIA SOCIAL DA VESPA NEOTROPICAL MISCHOCYTTARUS CONSIMILIS ZIKÁN, 1949 (HYMENOPTERA, VESPIDAE)
Aspects of the social biology of the Neotropical wasp Mischocyttarus consimilis Zikán, 1949 (Hymenoptera, Vespidae) - This work had for objective to study aspects social biology of the Neotropical wasp Mischocyttarus consimilis, of the which specifically understand: 1. colonial phenology; 2. architectonic model of nests and pattern of construction of nests;

9. Level of economic damage for Atta spp. (Hymenoptera: Formicidae) in a forest in the Atlantic Forest of the Vale do Rio Doce, Minas Gerais, Brazil / NÃvel de dano econÃmico para Atta spp. (Hymenoptera: Formicidae) em eucaliptais, em regiÃo de Mata AtlÃntica do Vale do Rio Doce, Minas Gerais.
The production and quality of eucalypt plantations have been studied in areas with different densities of ant nests aimed to regionalize models of estimating economic injury by leaf-cutting ants. The effects of the site and of the eucalyptus genetic material on leaf-cutting ant nests and of their nests on wood production were studied in a eucalyptus plantati

10. Geostatistics in the sequential sampling plan of leaf-cutting ant nests in eucalyptus plantations in the Atlantic forest region / GeoestatÃstica na amostragem sequencial de ninhos de formigas cortadeiras em eucaliptais em regiÃo de mata atlÃntica
One of the basic steps of the integrated pest management is the evaluation of pest population. For this, it is necessary to know how it is distributed on the field. Regarding the leaf-cutting ants, several studies have been developed to investigate their distribution as well as how to sample them adequately, but it is also necessary to improve such studies w

11. Dispersão de sementes por Atta robusta Borgmeier, 1939 (Hymenoptera: Formicidae) na restinga da Ilha de Guriri- ES / Seeds dispersal by Atta robusta Borgmeier, 1939 (Hymenoptera: Formicidae) in restinga forest Guriri Island, Brazil
This thesis characterized the use of fruits and seeds by Atta robusta Borgmeier, 1939, and the effects on the germination, seeds predation and seedlings survival. Fieldwork was carried out in the Guriri Island (1843S, 3945W), São Mateus, Espírito Santo State, Southeast Brazil, from March 2005 to March 2006. A. robusta was foraging 35 species of fruits and

12. Artificial nest predation: application, challenges and perspectives for the tropical areas / Predação de ninhos artificiais: aplicações, desafios e perspectivas para as áreas tropicais
The natural predation of the nests has been suggested as the principal cause to the decline of bird population, acting on the performance and community structure. Due to the difficulty of natural nest localization and monitoring, the artificial nests are used as a fast alternative to check the avian reproductive success. The artificial nest studies are widel
