1. Sociologia na América Latina: giros epistemológicos e epistêmicos
Resumo Este artigo destaca a emergência de uma sociologia geral na América Latina, organizada a partir de três diferentes perspectivas sociológicas: aquela “sobre” a América Latina, aquela “da” América Latina e aquela “na” América Latina. Estes diversos campos de sentidos foram organizados a partir das leituras intelectuais sobre as brecha

2. No fitness costs are induced by Spiroplasma infections of Aphis citricidus reared on two different host plants
Resumo Pulgões podem abrigar vários simbiontes secundários que alteram características ecológicas importantes, como defesa contra inimigos naturais, tolerância ao calor e utilização da planta hospedeira. Um desses simbiontes secundários, Spiroplasma, é estudado em Drosophila por alterar a razão sexual e interagir com o sistema imunológico do hosp

3. Hematological and biometric traits of tuvira Gymnotus inaequilabiatus (Valenciennes, 1839) (Gymnotiformes: Gymnotidae) from the Brazilian Pantanal
ABSTRACT This study describes the hematological and biometric characteristics of male and female Gymnotus species from the Pantanal, Mato Grosso do Sul state, Brazil. Fifty adult specimens of Gymnotus inaequilabiatus were weighed, measured, and then euthanized. Blood was collected by puncturing the celiac mesenteric vein to determine the hematocrit, hemoglob

4. Influência da agregação larval na história de vida de Ascia monuste orseis (Godart, 1819) (Lepidoptera, Pieridae) / Influence of larval aggregation on life-history traits of Ascia monuste orseis (Godart, 1819) (Lepidoptera, Pieridae)
In insects, the gregarious habit has been shown to improve foraging and defense against predation to both larval and adult stages. Egg clusters could also be beneficial through increased larval hatching. In this study, we tested the hypothesis that egg clusters and larval aggregations of the neotropical butterfly Ascia monuste orseis (Godart, 1819) (Pieridae

5. Evolução e ecologia de tricomas em Bignonieae (Bignoniaceae): estruturas morfológicas de defesa anti-herbivoria? / Evolution and ecology of trichomes in Bignonieae (Bignoniaceae): morphological structures of anti-herbivory defense?
This thesis focused on the evolutionary-ecology of trichomes in the tribe Bignonieae (Bignoniaceae), and in the potential defensive role of these structures against herbivores. More specifically, we characterized four trichome morphotypes found in vegetative plant parts of representatives of the Bignonieae, as well as studied the macro-evolutionary patterns

6. Resource Defense Polygyny by Hetaerina rosea Selys (Odonata: Calopterygidae): Influence of Age and Wing Pigmentation
Current evidence suggests that in Hetaerina damselflies males exhibit lek mating system. In this study, in order to answer if the same occurs in Hetaerina rosea Selys, we manipulated vegetation substrates used as territories and quantified the number of visiting females, males defending territories and fight intensity. We also examined whether body size and

7. Distribuição espacial de espécies arbóreas de cerrado: filogenia e traços de defesa contra herbivoria
A herbivoria deve promover um padrão de distribuição de traços de defesa em espécies de plantas coocorrentes, já que plantas similares são mais vulneráveis a herbívoros especialistas. O conservantismo dos traços é geralmente observado em linhagens de espécies de plantas, e assim, as relações filogenéticas entre as espécies também devem estar

8. Controle hormonal da defesa à herbivoria em tomateiro / Hormonal control of herbivory defense in tomato
Even though the cultivation of tomato has a high economical importance, this culture is classified as being of elevated risk because of it common infestation by pests and diseases. This problem makes this culture greatly dependent of the application of several agrochemicals, which leads to increase in cost of production, environmental damages and also facili

9. Sistemas de acasalamento com defesa territorial : evolução, regras das disputas e seleção de territorios em satirineos neotropicais / Mating systems with territorial defense : evolution, contest rules and territory selection in neotropical satyrine Butterflies
Territorial conflicts in flying insects may be resolved through many different ways. In male butterflies, size, age and motivation are often reported as important determinants of the winning chances. However, the rules used when fighting, the biological context that affects the intensity of agonistic behaviors, and the functional role of male traits in the c

11. Genetic structure and chemical defenses variaton in Brugmansia suaveolens (Solanaceae) / Estruturação genetica e variação de defesas quimicas em Brugmansia suaveolens (Solanaceae)
Populations patchily distributed tend to show high genetic structure and strong micro-evolutionary process evidences. Brugmansia suaveolens (Solanaceae) individuals are restrict to population patches. In this work, the genetic diversity of nine B. suaveolens populations was estimate by means of allozyme electrophoresis (chapter 1). Our results indicate high

12. In silico survey of resistance (R) genes in Eucalyptus transcriptome
A major goal of plant genome research is to recognize genes responsible for important traits. Resistance genes are among the most important gene classes for plant breeding purposes being responsible for the specific immune response including pathogen recognition, and activation of plant defence mechanisms. These genes are quite abundant in higher plants, wit
