1. Foraging behavior of two egg parasitoids exploiting chemical cues from the stink bug Piezodorus guildinii (Hemiptera: Pentatomidae)
Abstract: Several parasitoids attacking the same host may lead to competition. Adult parasitoids’ abilities to find, parasitize and defend hosts determine resource’s retention potential. In soybean, two egg parasitoid species, Telenomus podisi and Trissolcus urichi (Hymenoptera: Platygastridae), compete on the egg masses of Piezodorus guildinii (Hemipter

3. Forage sorghum-legumes intercropping: effect on growth, yields, nutritional quality and economic returns
ABSTRACT Cereal-legumes intercropping is among the most economical and effective agronomic strategies to boost forage biomass production, nutritional quality and monetary returns. This review synthesizes the research findings on how intercropping affects productivity, quality, competitiveness and economic viability of sorghum-legumes mixed, row and strip int

4. Isolation of Salmonella spp. in cattle egrets (Bubulcus ibis) from Fernando de Noronha Archipelago, Brazil
Abstract The growth of the population of cattle egrets (Bubulcus ibis) in the archipelago of Fernando de Noronha constitutes a threat to public health and biological diversity because of their competition with and predation on native species and the possibility of transmission of pathogens to human beings, livestock and native wildlife. The aim here was to s

5. OUTDOOR CULTIVATION OF Scenedesmus obliquus BR003 IN STIRRED TANKS BY AIRLIFT
ABSTRACT: The use of microalgae as a source of raw material for biofuel production has been highly targeted. Compared to other biological options for the capture and use of CO2, microalgae crops have the following advantages: high productivity, lack of competition with feed and food-based products, use of unproductive and non-arable land, and allowance of th

6. Interaction of β-Carbolines with DNA: Spectroscopic Studies, Correlation with Biological Activity and Molecular Docking
Quantitative interaction of twelve β-carboline derivatives with calf thymus deoxyribonucleic acid (ctDNA) using spectroscopic techniques was evaluated. The values of the binding constants (Kb) obtained for the complexes formed with the ctDNA ranged from 3.30 × 102 to 1.82 × 106 mol L−1, being the β-carbolines with the N,N-dimethylaminophenyl group at p

7. Identification of genes expressed by Cryptococcus gattii during iron deprivation
Cryptococcus neoformans and C. gattii are pathogenic yeasts that cause life-threatening diseases in humans and animals. Iron is an essential nutrient for virtually every organism as it functions as a cofactor in numerous essential enzymatic reactions. In the literature, the competition for iron between microbes and mammalian hosts during infection is well do

8. Intra annual seed production and availability of two morphotypes of Brosimum rubescens taubert in forests of the Colombian Amazon
We assessed the reproductive phenology, production, and availability of seeds for two morphotypes of Brosimum rubescens Taub. (Moraceae), locally known as black palosangre (BP) and white palosangre (WP) during an annual cycle in a 20-ha mega plot located in a primary forest at the El Zafire Biological Station, in the Colombian Amazon. We found that 87% and 4

9. Biomass production and nitrogen cycling in mixed plantation with Eucalyptus genotypes and Acacia mangium / Produção de biomassa aérea e ciclagem de nitrogênio em consórcio de genótipos de Eucalyptus com Acacia mangium
As plantações de eucalipto ocupam 20 milhões de hectares em solos altamente intemperizados. Plantações consorciadas de eucalipto com acácia têm potencial de melhorar a produtividade do povoamento, em relação às respectivas plantações homogêneas, através do efeito facilitador da fixação biológica de N pelas árvores de acácia. O objetivo foi

10. A função do agendamento entre duas olimpíadas: os jogos olímpicos de Beijing e do Rio de Janeiro
Today, China is a country well known and unknown, a big nation of Asia and the most populous of the Earth. However, although have a history dating back thousands of years, China is also an unknown country for most of the world. But because of the Olympic Games of 2008, China became famous. In this study, propose to discuss the origin of the games what the wo

12. Bioecologia e competição de duas espécies de parasitoides neotropicais (Hymenoptera: Braconidae e Eulophidae) de Liriomyza sativae Blanchard, 1938 (Diptera: Agromyzidae) / Bioecology and competition of two neotropical parasitoid species (Hymenoptera: Braconidae and Eulophidae) of Liriomyza sativae Blanchard, 1938 (Diptera: Agromyzidae)
We studied the biology of two species of parasitoids associated with Liriomyza sativae Blanchard, 1938 in the state of Rio Grande do Norte (RN), Brazil: the koinobiont larval-pupal parasitoid Opius (Gastrosema) scabriventris (Hymenoptera: Braconidae) and the larval idiobiont parasitoid Chrysocharis vonones (Hymenoptera: Eulophidae). The following parameters
