1. Interação trófica entre Podisus nigrispinus e Supputius cincticeps (Heteroptera: Pentatomidae) / Trophic interaction between Podisus nigrispinus and Supputius cincticeps (Heteroptera: Pentatomidae)
Prey may be more or less consumed by control biologic agents and presents three kinds of interspecific interactions, (1) synergism, increase of mortality of prey comparing to each natural enemy independently, when the foraging of one species facilitates the capture of pest by another natural enemies. (2) Total mortality of the pest to natural enemies equals

2. Interação entre Cylindrospermopsis raciborskii e Microcystis aeruginosa: implicações no crescimento de culturas e na produção de microcistinas / Interaction between Cylindrospermopsis raciborskii and Microcystis aeruginosa: implications in cultures growth and microcystins production
Cyanobacteria play important ecological role in many terrestrial and aquatic ecosystems. However, they become a public health problem when synthesize secondary toxic compounds, known as cyanotoxins, which may act on several organisms. Impacted aquatic systems favor their growth and these microorganisms can become dominant due to mechanisms that confer them a

3. Germinação, competitividade com a cultura da soja e resposta biológica a aplicações de glyphosate para plantas de trapoeraba (Commelina benghalensis L.) / Germination, competitiveness with the soybean crop and biologic response to glyphosate applications of Bengal dayflower plants (Commelina benghalensis L.)
In areas where the herbicide glyphosate is used frequently, populations of the weed Bengal dayflower (Commelina benghalensis) have been selected, due to the species tolerance to the action of that herbicide. This way, the use of alternative management is necessary, which are dependent upon deep knowledge on species biology; as well as, the efficient chemical

4. Contribuições da história e filosofia da ciência para o ensino da evolução biológica
The present study has as its most important goal to identify and discuss aspects in relationship to the comphrension of Biological Evolution. The presentation of subject has been distorted and the public, in general, has had influences on its understanding. Some authors made researches on the understanding of such subject with some students of High School, i

5. Spatial pattern analysis of trees of four forest communities in southeastern Brazil, using Ripleys K function. / Análise dos padrões espaciais de árvores em quatro formações florestais do estado de São Paulo, através de análisses de segunda ordem, como a função K de Ripley.
Tree spatial patterns are influenced by abiotic and biotic environment. Among the main abiotic factors are topography, light, nutrients, soil and water availability. Among biotic factors are density-dependent processes, as intraespecific and interespecific competition, herbivory, pathogens, phenology and seed dispersion. Investigation of tree spatial pattern
